STRONG EARTHQUAKE IN IZU ISLANDS, JAPAN; ENHANCED ACTIVITY IN GREECE

 

EARTHQUAKE SUMMARY FOR NOVEMBER 29, 2021

 

The strongest earthquake of the day was an M 6.4-6.6 in the Izu Islands southeast of Honshu, Japan. It was widely felt in Honshu due to its deep focus. NEIC reported intensity IV in Chiba, Shizuoka, and II-III in Kanagawa Prefectures. This follows a strong earthquake in the Bonin Islands two days ago and may indicate a period of active seismicity in this area for the next several weeks. This event is at the eight node (135 degrees) from the M 7.5 earlier in the day in northern Peru and may have been promoted by energy from that source. This is the strongest earthquake in the Izu Islands within about 200 km of this epicenter in the past 30 years. An M 6.5-6.6 hit about 250 km to the north of this on August 12, 2009 with events of M 6.4 in the Izu Islands on August 11, 1992 and October 23, 2006. Forecast 138994 had expected today's activity within about 100 km was likely at the end of November. This epicenter is also located at 103 degrees from the Guerrero, Mexico earthquake of September 8, 2021 (M 7.1) and at the sixth node (60 degrees) from the Vanuatu earthquake of October 2 (M 7.3) and was probably promoted by energy from those sources.

A moderate earthquake of M 4.9 was widely felt in the Dodecanese Islands of Greece today. NEIC reported maximum intensity IV in Aylos Kirikos, Ino Siros, Kusadasi and II-III in Neon Karlovasion, Samos, Khios, Khorion, Ios and in Turkey at Bodrum, Mugla, Izmir, Kusadasi, Ayhdin and Urla, Izmir. This epicenter is located at 103 degrees from the M 7.5 in Peru which occurred yesterday and had been expected as a far-field aftershock in the previous issue of this report as:

 

"Far field triggering from Peru is not expected to be strong. The antipode is at 4N 104E north of an active zone south of Sumatra where some enhanced seismicity is expected in coming days. The 103 degree distance passes through eastern Europe, Turkey, Eastern Africa, New Zealand, and the Komandorsky Islands north of Kamchatka. These areas may also see some enhanced activity but a major earthquake in these areas triggered from Peru is unlikely at this time." (November 29, 2021)

 

This is the strongest earthquake in the Dodecanese Islands within about 200 km of this epicenter since August 7, 2021 when an event of M 5.1 occurred. An M 7.0  about 100 km southwest of this occurred in the Dodecanese Islands on October 30, 2020. These may be regional aftershocks of that mainshock. Forecast 138968 had expected enhanced regional seismicity in this area was likely at the end of November. This activity, in addition to being at 103 degrees from Peru is also at that distance from the M 7.0 in Guerrero, Mexico of September 8; the M 8.1 in the South Sandwich Islands of August 12, 2021 and was probably promoted by energy from those sources.

The strongest activity in or near the U.S. or Canada today continued in the northern Gulf of California. The strongest events in this swarm today were an M 4.7 and 4.6. This is the strongest earthquake in this region in at least a year following an M 4.6 on November 24, 2021 and appears to confirm that this swarm is accelerating. The M 4.7 occurred within a couple of minutes of local solar noon and was probably promoted by high tidal stresses at this hour. It was followed by a strong series of local aftershocks. Forecast 138998 had expected today's activity was likely  within about 25 km around November 27. This activity is located near the seventh node (51 degrees) from the M 7.5 in Peru yesterday. This summary had expected enhanced seismicity in this area was likely following that event as:

 

 

"It is of some interest to note that this area (northern Gulf of California) is located at the 7th node (51.4 degrees) from the M 7.5 in Peru and may see a change in seismicity related to energy from that source in coming days." (November 28-29, 2021)

A swarm of light earthquakes of M 3.9-4.0 occurred off the west coast of South Island, New Zealand today. These may be related to the M 7.5 in Peru yesterday as they occurred at 105 degrees from that epicenter and had been expected as far-field activity following it (see above). This epicenter is located at 102-105 degrees from strong earthquakes recently in Peru, the Alaska Peninsula and Guerrero, Mexico and may have been promoted by energy from those sources.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MAJOR EARTHQUAKE HITS THE AMAZON IN NORTHERN PERU

 

EARTHQUAKE SUMMARY FOR NOVEMBER 28, 2021

 

A major earthquake of M 7.5 damaged sections of northern Peru today. NEIC reported it was felt with damaging intensity VIII in Peru at Barranca, Yantzaza Zamora, Ecuador,  Chachapoyas; VII in Roja, San Martin; VI in Moyobambo, Lamas, Jaen, Cajamarca, Sauce, V in Bagua Grande Amazonas and at Zamora, Ecuador. Reuters reported the quake was felt throughout much of Peru as far as Lima and destroyed at least 75 homes with 200 others damaged and 81 uninhabitable. But no deaths were reported with this earthquake which hit a remote area of the Amazon. At least four persons were injured in the quake  which also damaged seven places of worship; two shopping centers and businesses. While power was out to much of the area, online networks reported stretches of road blocked by landslides. In Jalca Grande in Chachopoyas province, the tower of the local church collapsed. This appears to be the culmination of the enhanced seismicity in northern South America which has been detailed in previous issues of this summary as:

 

 

"A moderate earthquake of M 5.1 was felt in northern Peru today. NEIC reported maximum intensity IV in Lamas, San Martin. This continues the elevated seismicity in northern Peru and Ecuador which has been occurring in the past several days. These events are generally located about 103 degrees from the M 7.3 in Vanuatu of October 2, 2021 - the last major earthquake in the world and could indicate regional stress preceding a stronger event in Peru or Ecuador. Other strong earthquakes in the past two weeks at or near 103 degrees from the October 2 Vanuatu mainshock have occurred as an M 6.2 in Nicaragua on November 9;  an M 6.0 in the South Indian Ocean of November 15; an M 6.0 south of Africa on October 26; an M 6.0 in the South Sandwich Islands of November 1; an M 5.8 in Guatmala on November 18;i and M 5.4 in El Salvador on November 23 and has included all earthquakes of M>=5.8 in the western hemisphere in the past month.

Other areas near 103 degrees from Vanuatu such as the Missouri and Oklahoma/Kansas in central U.S. have seen lesser but significant seismic enhancement during this period. This is the strongest earthquake in northern Peru within about 150 km of this epicenter since an M 8.0 on May 26, 2019 about 150 km to the northeast of today's epicenter and may be a regional aftershock of that mainshock. Forecast 138904 had expected today's activity around November 23." (November 27, 2021)

 

Today's earthquake in Peru is at 104-105 degrees from the M 7.2 in Vanuatu of October 2, 2021, the last major earthquake in the world. It is also the strongest earthquake in the world since an M 8.1 on August 12, 2021 in the South Sandwich Islands and an M 8.2 in the Alaska Peninsula or July 29, 2021, four months ago. The only earthquake of larger magnitude within about 300 km of today's epicenter in the past 30 years was an M 8.0 about 200 km southeast of this  on May 26, 2019. Earthquakes of M 7.4-7.5 hit within about 300 km on February 22, 2019 and September 26, 2005. When the M 8.0 occurred in May, 2019, this summary noted the 103 triggering distance as:

 

"In recent issues of this summary seismic enhancement of unusual earthquakes near 103 degrees from the M 7.5 in New Britain has been detailed. With the M 8.0 in Northern Peru yesterday, this dynamic is likely to change encouraging promoted seismicity near 103 degrees from that epicenter in the coming days." (May 27, 2019)

 

The earthquake in May, 2017 also occurred, like that today, on the 22nd day of  the lunar month.

 

A possible regional foreshock occurred in Ecuador on November 23 with M 4.9.

This summary noted this event at the time as:

 

"An earthquake of M 4.9 in Ecuador today was widely felt and caused minor damage and disruption. NEIC reported maximum intensity V in Ecuador at Otavalo, IV in Qujito, Sanglqui, and Cayambe and II-III in Cotacachi, Santo Domingo, Tena and Pasto. The only earthquakes in Ecuador within about 200 km of this epicenter in the past year with M>=4.9 occurred on June 14 and 15, 2021 - both with M 4.9. Stronger earthquakes 300-400 km to the southeast have since occurred in Ecuador including an M 6.1 on July 30, 2021. Forecast 138626 had expected today's activity within about 100 km was likely around November 19. This activity is at 105 degrees from the M 7.2 in Vanuatu of October 2 and may have been promoted by energy from that source." (November 24, 2021)

 

Far field triggering from Peru is not expected to be strong. The antipode is at 4N 104E north of an active zone south of Sumatra where some enhanced seismicity is expected in coming days. The 103 degree distance passes through eastern Europe, Turkey, Eastern Africa, New Zealand and the Komandorsky Islands north of Kamchatka. These areas may also see some enhanced activity but a major earthquake in these areas triggered from Peru is unlikely at this time.

 

The activity in the northern Gulf of California and Baja California was somewhat reduced today with three  events of M>=4 in the area. It is of some interest to note that this area is located at the 7th node (51.4 degrees) from the M 7.5 in Peru and may see a change in seismicity related to energy from that source in coming days. Much of today's activity occurred near local solar midnight and may have been enhanced by tidal stresses. Forecast 138998 had expected continuing activity in this area in late November.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

SOUTH AMERICAN SEISMIC ENHANCEMENT CONTINUES

 

EARTHQUAKE SUMMARY FOR NOVEMBER 27, 2021

 

An M 5.1 was widely felt in Central Peru today. NEIC reported it was felt with maximum intensity V in Lima with IV in San Luis, Muacho, Mala, Lima, Matucana and III in Santa Maria, Huaral, Nicolas de Pierola, and Chica, Peru. This continues strong seismicity in the area of northern and central Peru as noted in the previous issue of this report:

 

"A moderate earthquake of M 5.1 was felt in northern Peru today. NEIC reported maximum intensity IV in Lamas, San Martin. This continues the elevated seismicity in northern Peru and Ecuador which has been occurring in the past several days. These events are generally located about 103 degrees from the M 7.3 in Vanuatu of October 2, 2021 - the last major earthquake in the world and could indicate regional stress preceding a stronger event in Peru or Ecuador." (November 26-27, 2021)

 

This activity expanded down the South American subduction zone today with moderate quakes of M 4.7-4.8 in Chile at Atacama and La Araucania. Moderate earthquakes were also felt in the Lima, Peru and areas of central and southern Peru today. The earthquake of M 5.1 in Central Peru today was expected within about 100 km around November 26 in forecast 139104. The only earthquake of larger magnitude within about 200 km of this epicenter in the past year was an M 5.8 about 100 km to the southeast on June 23, 2021. This epicenter is at 102 degrees from the M 7.3 in Vanuatu of October 2 and may have been promoted by energy from that source.

A moderate earthquake of M 5.3 also shook regions of eastern New Guinea PNG today with NEIC reporting maximum intensity V in Popondetta Oro and II-III in Port Moresby and  Milne Bay, PNG. An M 5.4 preceded this event to the east in the North Solomon Islands, PNG. It was felt with maximum intensity V in Buin and III in Arawa, Solomon Islands. This epicenter is far to the south of the normal seismicity in this area. The last event of M>=5.4 within about 200 km of this epicenter was an M 5.5 about 100 km to the north on August 20, 2015. The last of significantly larger magnitude was an M 6.0 on June 29, 1999. Forecast 138911 had expected regional seismic enhancement was likely around November 26.

The strongest earthquake in the U.S. or Canada today was an M 4.3 in Northern Alaska. It was followed by an aftershock of M 3.8. NEIC reported this earthquake of M 4.3 in Northern Alaska was felt with intensity II-IV in the area(s) of Northern Alaska at Venetie and Bettles Field. The last earthquake with M>=4.3 within about 200 km of this epicenter was an M 4.4 on May 11, 2018. Forecast 139094 had expected today's event was likely to the north in the active zone near the north shore of Alaska most likely to occur around November 26.

The strongest earthquake in the U.S. or Canada outside Alaska today occurred as an M 4.0 off the coast of northern California. NEIC reported it was felt in Northern California with intensity II in McKinleyville and Eureka. A series of light aftershocks followed the M 3.4-4.0 mainshock. This activity occurred near local solar midnight and may have been promoted by high tidal stresses which maximize near this hour. The last activity of larger magnitude in this area off the coast of northern California occurred June 4, 2021 when an M 5.9 hit about 100 km north of today's epicenter. No intervening aftershocks of M>=4.0 have occurred since then. Forecast 139049 had expected today's activity within about 30 km was likely around November 30.

An unusually large M 4.4 shook the area of northern Sicily, Italy today. NEIC reported this earthquake of M 4.4 in Sicily, Italy was felt with intensity III-IV in the area(s) of Sicily, Italy. This does not appear to be related to the ongoing eruption of Etna on Sicily. It is the strongest earthquake within about 100 km of this epicenter since a similar M 4.4 on October 24, 2020. The last earthquake of larger magnitude in this area was an M 4.5 on October 14. 2015. Forecast 138985 had expected today's event was likely in this area around November 27. This epicenter is at 102-103 degrees from the M 7.1 in Molucca of August 11 and the M 8.1 in the South Sandwich Islands of August 12 and may have been promoted by energy from those sources.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

SEISMICITY NEAR 103 DEGREES FROM VANUATU ENHANCED

 

EARTHQUAKE SUMMARY FOR NOVEMBER 26, 2021

 

A moderate earthquake of M 5.1 was felt in northern Peru today. NEIC reported maximum intensity IV in Lamas, San Martin. This continues the elevated seismicity in northern Peru and Ecuador which has been occurring in the past several days. These events are generally located about 103 degrees from the M 7.3 in Vanuatu of October 2, 2021 - the last major earthquake in the world and could indicate regional stress preceding a stronger event in Peru or Ecuador. Other strong earthquakes in the past two weeks at or near 103 degrees from the October 2 Vanuatu mainshock have occurred as an M 6.2 in Nicaragua on November 9;  an M 6.0 in the South Indian Ocean of November 15; an M 6.0 south of Africa on October 26; an M 6.0 in the  South Sandwich Islands of November 1; an M 5.8 in Guatmala on November 18;i and M 5.4 in El Salvador on November 23 and has included all earthquakes of M>=5.8 in the western hemisphere in the past month. Other areas near 103 degrees from Vanuatu such as the Missouri and Oklahoma/Kansas in central U.S. have seen lesser but significant seismic enhancement during this period. This is the strongest earthquake in northern Peru within about 150 km of this epicenter since an M 8.0 on May 26, 2019 about 150 km to the northeast of today's epicenter and may be a regional aftershock of that mainshock. Forecast 138904 had expected today's activity around November 23.

The strongest earthquakes felt in the world today were of M 5.3 and M 5.3 in the region of Tonga and Samoa. NEIC reported these earthquakes were felt with intensity IV in Samoa at Apia and Tafatafa and Tulaele and in American Samoa with lesser intensity. Forecasts 138841 and 139109 had expected today's event within about 150 km was likely around November 19-26. This activity is located at 103 degrees from the M 7.2 in Haiti of August 14 and from the M 8.1 in the South Sandwich Islands of August 12 and may have been promoted by energy from those sources.

The strongest earthquake in the world today was an M 5.7 in the Bonin Islands, Japan. It may have lightly felt in southern Honshu, Japan. This is the strongest earthquake in the Bonin Islands within about 200 km of this epicenter sinc an M 5.8 on July 30, 2020. The last event of M>=6 in this region was an M 6.1 on September 20, 2016 more than five years ago. Forecast 138994 had expected this activity in this are was likely around November 23. This earthquake is located at 104 degrees from the M 7.2 in Guerrero, Mexico of September 8 and may have been promoted by energy from that source.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG QUAKES SHAKE INDIA AND SOLOMON ISLANDS

 

EARTHQUAKE SUMMARY FOR NOVEMBER 25, 2021

 

The strongest earthquake in the world today was an M 6.2 on the Myanmar-India border. NEIC reported it was felt with maximum intensity VIII in North Vanlaiphai, India; VII in Rangamali, Bangladesh and Champhal, Mizoram, India and VI in Lunglei and Serchhip, and V in Alzaei and Mamit, Mizoram, India and in Bangladesh at Ranguna and Bandarban with IV in Saiha, Mizoram, India. The press reported light to moderate regional damage with this earthquake. This is the strongest earthquake within about 250 km of this epicenter since an M 6.9 on April 13, 2015 and an M 6.8 on November 11, 2012. In the past 30 years similar earthquakes also hit the region on June 15, 1992 and January 5, 1991. Forecast 138958 had expected today's activity in this area was likely around November 25. This epicenter is located at 101 degrees from the M 8.1 in the Kermadec Islands of March 4, 2021 and may have been promoted by energy from that source.

An M 6.0 was also widely felt in the Solomon and Santa Cruz Islands today. NEIC reported maximum intensity VI was felt in the Solomon Islands at Lala, Temptu amd III in Guadalcanal and II in Sola and Luganville, Vanuatu. The mainshock occurred near local solar midnight and may have been promoted by strong tidal stresses. It was followed by a series of moderate aftershocks including those of M 4.9, 4.7 and 4.4 among others. The mainshock of M 6.0 is the strongest earthquake within about 200 km in the Santa Cruz Islands since an M 6.0 on August 20, 2019. The last in the Santa Cruz Islands of larger magnitude was an M 7.0 on July 18, 2015. Last year an M 6.6 hit south of this in northern Vanuatu on May 12, 2020. Forecast 139116 had expected today's activity within about 50 km was likely at the end of November. This epicenter is at the fifth node (72 degrees) from the M 8.2 in the Alaska Peninsula of July 29, 2021 and may have been promoted by energy from that source.

A M 5.8 also occurred in the Fiji Islands east of southern Vanuatu today.  This earthquake was not reported felt in this remote epicentral area. It appears to be the second strongest aftershock to date of the M 7.3 which hit the region on October 2, 2021, the last major earthquake in the world. The strongest aftershock was an M 6.9 on October 9, 2021. Forecast 139131 had expected major enhancement in this aftershock zone was likely within about 50 km of today's epicenter around November 24.

An unusually larger M 3.1 was lightly felt in the region near Godbout, Quebec in the St. Lawrence Valley region today. The most recent earthquake in the St. Lawrence Valley of equal or larger size occurred nearly a year ago on December 28, 2020 with M 3.4. An event about 300 km to the southwest of today's epicenter occurred with M 3.3 on May 17, 2021. Forecasts 139030 and 139037 had expected today's activity within about 15 km was likely between November 24 and 28.

The swarm of earthquakes in the northern Gulf of California continued today with elevated levels of seismicity. Earthquakes of M 4.5, 4.4 and 4.4 were the largest in the group today. This series began with the new moon in early November and has continued off-and-on daily since that time. The largest earthquakes to date in this swarm were an M 4.6 on November 24 and an M 4.5 on November 3, 2021. Forecast 138998 had expected enhanced regional seismicity within about 25 km of today's activity was likely around November 27.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKE SHAKES TAIWAN

 

EARTHQUAKE SUMMARY FOR NOVEMBER 24, 2021

 

The strongest earthquake in the world today occurred in Taiwan with M 5.2.

CWB reported this earthquake was felt with intensity III in Hualien, II in Yilan, Taipei and Nantou and I in Miaoli, Chiayi, Changhua, Yunlin, Hsinchu Counties, Taiwan. This appears to be the strongest aftershock of an M 6.2 which occurred about 75 km northwest of this epicenter a month ago on October 24, 2021. Forecast 138954 had expected today's event was likely around November 24  within about 100 km of this epicenter.

The strongest earthquake in the U.S. or Canada today was an M 4.0 off the coast of Oregon. It was reported lightly felt in Eugene, Oregon. It is part of a sequence of events in this region over the past four days following the full moon of November 19 and was probably promoted by high tidal stresses. The strongest earthquakes in this swarm were an M 4.6 on November 20 and an M 4.4 on November 21. An M 3.1 hit the area on November 23. Forecast 139051 had expected today's activity within about 25 km was likely around November 24.

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

M 4.9 SHAKES SAN DIEGO, CALIFORNIA; MODERATE QUAKES SHAKE FIJI

 

EARTHQUAKE SUMMARY FOR NOVEMBER 23, 2021

 

The largest earthquake in the U.S. or Canada today was an M 4.9 in the area south of San Diego, California. This event appears to have been widely felt in San Diego, California. It is probably an extension of the strong series southeast of this in Baja and the northern Gulf of California which began in early November. It is the strongest earthquake within about 100 km south of San Diego since an M 4.9 on October 16, 2005 more than 15 years ago. Forecast 139002 had expected the area would seen enhanced seismicity within this area around November 26. A major earthquake - the Superstition Hills quake occurred 34 years ago today on November 24, 1987 in the area east of this epicenter, (see history section).  This activity is at 107 degrees from the M 7.1 in the Molucca Sea of August 11 and may have been promoted by energy from that source.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKE SHAKES EL SALVADOR

 

EARTHQUAKE SUMMARY FOR NOVEMBER 22, 2021

 

The strongest earthquake in the world today was an M 5.4 in the area off the southern coast of El Salvador. NEIC reported maximum intensity IV in El Salvador at Acajutla and II-III in Sonsonate, Antiguo Cuscatlan, San Salvador, Sensuntepeque an din Guatemala at Palin and Santa Catarina Pinula. This is the strongest earthquake felt in El Salvador since an M 5.9 and 5.6 on May 12, 2021 about 50 km north of today's epicenter. The M 5.4 today may be an aftershock of those events in May. It occurred within minutes of local solar midnight and may have been promoted by high tidal stresses which maximize near this hour. Forecast 138932 had expected today's event within about 100 km of this epicenter was likely around November 24.

A moderate earthquake of M 4.5-4.6 was widely felt in the Dominican Republic today. NEIC reported maximum intensity V in the Dominican Republic at Villa Bisono and Licey al Medio; IV in Puerto Plata, Sosua and II-III in Maimon, Montellano, Santiago and at Altamira, Puerto Rico, Santiago. This is the largest earthquake within about 150 km of this epicenter in nearly a year - since an M 4.6 on October 19, 2020. The last of significantly larger magnitude in this area was an M 5.2 on September 23, 2018. Forecast 138948 had expected today's event in this region was likely around November 27.

The volcanic eruption of Cumbre Viejo, Canary Islands continued at high levels today. The strongest earthquake today was an M 4.7 the second highest magnitude in the current eruption of two months duration. Other moderate earthquakes of M 4.3, 4.2 and 4.2 were also recorded along with many of smaller magnitude. The lava flows from this eruption have now formed a new delta as they  pour into the sea. Forecast 138954 had expected today's activity in the Canary Islands was likely to continue through late November.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKE SHAKES DOMINICAN REPUBLIC

 

EARTHQUAKE SUMMARY FOR NOVEMBER 21, 2021

 

A moderate earthquake of M 4.5 was widely felt in the Dominican Republic today. NEIC reported maximum intensity V in the Dominican Republic at Villa Bisono and Licey al Medio; IV in Puerto Plata, Sosua and II-III in Maimon, Montellano, Santiago and at Altamira, Puerto Rico, Santiago This is the largest earthquake within about 150 km of this epicenter in nearly a year - since an M 4.6 on October 19, 2020. The last of significantly larger magnitude in this area was an M 5.2 on September 23, 2018. Forecast 138948 had expected today's event in this region was likely around November 27.

The largest earthquake in the world today was an M 5.2 in the continuing aftershock sequence following the M 8.1 of August 12, 2021. The last aftershock of M>=5.2 was an M 5.2 on November 12 at this same epicenter. Forecast 138886 had expected today's activity in the South Sandwich Islands was likely around November 17.

The strongest earthquake in the U.S. or Canada today was an M 4.4 off the coast of Oregon. A similar event of M 4.6 occurred in the area on November 20 and was  noted in this summary as:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.6 off the Coast of Oregon. NEIC reported it may have been felt in Oregon in Coos Bay, Salem, and Portland and in Kirkland, Washington. This is the strongest earthquake off the coast of Oregon within about 200 km of this epicenter since an M 5.4 on April 29, 2021.  Today's event appears to have been promoted by the lunar eclipse and full moon today as it occurred in a area and near a longitude where strong seismic enhancement had been expected (in previous issues of this summary as:

 

"The full moon arrived at 08:58 UT on November 19, 2021. Longitudes which were sub-solar at this time are located at sub-solar (local solar noon) at this hour near 45 East in the east  and at local solar midnight at 135 West longitude.  This continues the likely tidal triggering with the new Moon of November and in the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 16-23, 2021). This is a partial lunar eclipse, the longest of the century and will continue for up to 3.5 hours. In North America it is likely to cast a red rusty glow on the moon. Since the sun-earth-moon alignment is nearly exact during eclipses this will likely increase the intensity of tidal stresses and related seismicity near the time of the eclipse." (November 16-21, 2021)

 

Forecast 138778 had expected enhanced seismicity within about 50 km of today's epicenter was likely in mid-November." (November 19-20, 2021)

A pair of light earthquake of M 2.6 and M 2.4 were widely felt in Virginia and Tennessee today. NEIC reported the M 2.6 was felt with maximum intensity IV in Nickelsville  with II-III in Virginia at Abingdon, Bristol, Meadowview, Lebanon and in Tennessee at Bristol, Bluff City and Blountville.  Three earthquakes of M>=2.6 have been felt in Virginia in the past year - an M 2.6 on September 27;

an M 2.9 on February 12 and an M 2.6 on February 4, 2021. Forecasts 138984 and 138714 had expected this activity was likely between November 14 and 22. This activity is at 104 degrees from the M 8.1 of August 12 in the South Sandwich Islands and may have been promoted by energy from that source.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKE SHAKES AZERBAIJAN

 

EARTHQUAKE SUMMARY FOR NOVEMBER 20, 2021

 

A strong earthquake was felt today as an M 5.1 in Azerbaijan. NEIC reported it was felt with maximum intensity V in Azerbaijan at Samaxi, IV in Deveci, Goycay, and II-III in Sumqayit, Baku, Kesla and Parsabad. A similar M 5.1 hit northern Azerbaijan on January 2, 2021 but the last event of larger magnitude was an M 5.3 on June 5, 2018 about 200 km to the north west of today's epicenter. The last earthquake in the area within about 200 km of significantly larger magnitude was an M 5.3 on August 1, 2016. Forecast 138757 had expected regional enhancement of seismicity in the area was likely around November 18. Today's event occurred near the longitude of maximum tidal stress with the full moon of November 19 and was probably promoted by stresses associated with that alignment as noted in previous issues of this summary:

 

"The full moon arrived at 08:58 UT on November 19, 2021. Longitudes which were sub-solar at this time are located at sub-solar (local solar noon) at this hour near 45 East in the east  and at local solar midnight at 135 West longitude.  This continues the likely tidal triggering with the new Moon of November and in the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 16-23, 2021). This is a partial lunar eclipse, the longest of the century and will continue for up to 3.5 hours. In North America it is likely to cast a red rusty glow on the moon. Since the sun-earth-moon alignment is nearly exact during eclipses this will likely increase the intensity of tidal stresses and related seismicity near the time of the eclipse." (November 17-21, 2021)

 

This earthquake is located at 142 degrees from the M 8.1 in the Kermadec Islands of March 4 and at 101 degrees from the M 7.2 in Haiti of August 14 and may have been promoted by energy from those sources.

The strongest earthquake of the day was an M 5.9 in the northern Kermadec Islands, New Zealand. It was not reported felt in this remote area. This is the strongest earthquake within about 200 km of this epicenter since an M 6.3 on August 31, 2021. Both of these area aftershocks of the M 8.1 Kermadec mainshock of March 4, 2021. Forecast 138872 had expected enhanced seismicity in this area was likely around November 19.

A strong earthquake of  M 5.7 also occurred today in Vanuatu. NEIC reported it was felt with intensity IV in Vanuatu at Luganville, and Norsup. This is the strongest earthquake within about 200 km of this epicenter since an M 6.9 in Vanuatu on August 18, 2021 and may be a regional aftershock of that mainshock. Forecast 138851 had expected this activity within about 50 km was likely in mid-November. This earthquake is located at 105 degrees from the M 8.1 in the South Sandwich Islands of August 12 and may have been promoted by energy from that source.

The strongest activity in or near the U.S. or Canada today occurred in the  swarm in the northern Gulf of California. This continues similar activity in the region which has been ongoing throughout November. The largest of today's events was an M 4.4 which occurred near local solar midnight and may have been promoted by strong tidal stresses. Forecast 138731 had expected continued enhanced seismicity in this area was likely in mid-November.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKES SHAKE VANUATU AND MINDANAO, PHILIPPINES

 

EARTHQUAKE SUMMARY FOR NOVEMBER 19, 2021

 

An earthquake of M 5.4 was felt widely in Mindanao, Philippines today. NEIC reported maximum intensity IV in Southern Mindanao at Mayo and Pundaguitan and II-III in Nabuntura, Davao, Maltia, Digos, Padada. Brasilisa. A foreshock of M 5.1 was felt with intensity II-III in Pundaguitan and Bato, Southern Mindanao. This is the strongest earthquake in Mindanao within about 150 km of this epicenter since an M 7.1 hit the same area on August 11, 2021. This is probably the strongest regional aftershocks of that event since mid-August.  Forecast 138612 had expected today's activity was likely within about 100 km around November 20.

An M 5.6 was also felt with intensity II-III in Vanuatu today. NEIC reported it was felt in Vanuatu at Isangel, We Iles and Fayaoue Iles, New Caledonia. This is the strongest earthquake within about 200 km of this epicenter in Vanuatu since an M 6.1 on January 8, 2021 and an M 5.6 on March 29, 2020. Forecast  138851 had expected today's event in this area was likely around November 19.

The strongest earthquake in the U.S. or Canada today was an M 4.6 off the Coast of Oregon. NEIC reported it may have been felt in Oregon in Coos Bay, Salem, and Portland and in Kirkland, Washington. This is the strongest earthquake off the coast of Oregon within about 200 km of this epicenter since an M 5.4 on April 29, 2021.  Today's event appears to have been promoted by the lunar eclipse and full moon today as it occurred in a area and near a longitude where strong seismic enhancement had been expected (in previous issues of this summary as:

 

"The full moon arrived at 08:58 UT on November 19, 2021. Longitudes which were sub-solar at this time are located at sub-solar (local solar noon) at this hour near 45 East in the east  and at local solar midnight at 135 West longitude.  This continues the likely tidal triggering with the new Moon of November and in the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 16-23, 2021). This is a partial lunar eclipse, the longest of the century and will continue for up to 3.5 hours. In North America it is likely to cast a red rusty glow on the moon. Since the sun-earth-moon alignment is nearly exact during eclipses this will likely increase the intensity of tidal stresses and related seismicity near the time of the eclipse." (November 16-21, 2021)

 

Forecast 138778 had expected enhanced seismicity within about 50 km of today's epicenter was likely in mid-November.

An unusual earthquake of M 3.4 also shook regions of eastern Montana today.

This event occurred within about 30 minutes of local solar noon and was probably enhanced by strong tidal stress changes with the full moon. This area of eastern Montana has been active in the past four months with an M 4.1 on July 6, 2021 and an M 3.5 on October 6, 2021, the first such activity within about 150 km of today's epicenter since an M 4.0 on August 22, 2009. The only event in the past 30 years within about 100 km of today's epicenter with M>=3.4 was an M 3.6 on December 23, 1991. Forecast 138793 had expected activity in this region was likely in mid-November. Forecast 138486 had anticipated enhanced seismicity in northern Colorado in this time period.

A moderate earthquake of M 5.2 was also felt in eastern Turkey today. NEIC reported this earthquake of M 5.1 in Eastern Turkey was felt with intensity II-III in the area(s) of Eastern Turkey with IV in Erzurum at Horasan, Erzurum and II in Trabazon. Also reported in Batumi Ajaria, Georgia. It was located near the longitude of maximum tidal stress from the full moon today and occurred several hours into that eclipse and was probably enhanced by those stresses. An event of M 5.4 hit about 200 km southeast of this on June 25, 2021 but the last event within about 150 km of this epicenter of M>=5.2 2as an M 5.9 on June 14, 2020 and an aftershock of M 5.4 on June 15, 2020, Forecast 138750 had expected enhanced seismicity in this area around November 18.

An unusual M 4.6 earthquake in Rajasthan, India may also have been enhanced by tidal effects. This event occurred near local solar midnight in an area where longitudinal seismic enhancement was considered likely (see above). This is the strongest earthquake in Rajasthan, India within about 200 km of this epicenter since an M 4.6 on November 9, 2010 - the only other such quake  in this area of equal or greater magnitude in the past 30 years at least. Forecast 138680 had expected today's event in this area was likely around November 20.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG EARTHQUAKE SHAKES NEW IRELAND

 

EARTHQUAKE SUMMARY FOR NOVEMBER 18, 2021

 

Seismicity continued today at strong levels around the world. Among these were an M 5.8-5.9 in Guatemala and an M 6.5 earthquake, the strongest event in the world since early October when an M 7.2 occurred in the Vanuatu/Loyalty Islands region in the area of New Ireland, Papua New Guinea. It was likely promoted by high tidal stresses associated with the full moon/eclipse today as noted in previous issues of this summary:

 

"The full moon will arrive at 08:58 UT on November 19, 2021. Longitudes which area sub-solar at this time are located at sub-solar (local solar noon) at this hour near 45 East in the east  and at local solar midnight at 135 West longitude.  This continues the likely tidal triggering with the new Moon of November and in the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 16-23, 2021). This is a partial lunar eclipse, the longest of the century and will continue for up to 3.5 hours. In North America it is likely to cast a red rusty glow on the moon. Since the sun-earth-moon alignment is nearly exact during eclipses this will likely increase the intensity of tidal stresses and related seismicity near the time of the eclipse." (November 16-18, 2021)

 

The strong earthquake of M 6.5 was felt today in the region of New Ireland, PNG. This event was felt with intensity II-III in New Britain in Rabaul, Panguna, North Solomons, Namatanai, New Ireland, Kimbe, Kavieng and Port Morescy, Papua New Guinea. An aftershock of M 5.4 was felt with intensity IV in Panguna North Solomons, Papua New Guinea.

 

Today's earthquake occurred within about half an hour of local solar midnight and was preobably promoted by high tidal stresses associated with the full moon/eclipse today. The area saw several moderate foreshocks yesterday which were noted in this summary in the previous issue as:

 

 

"The strongest earthquake in the world today outside the America's was an M 5.2 in the area of New Ireland. This event was probably promoted by the current geomagnetic storm as it lies near the geomagnetic equator. This region including Indonesia as seen a series of strong earthquake associated with the previous geomagnetic storm and could see another strong event in this region with the current geomagnetic storm. Forecast 138630 had expected this event within about 150 km was likely around November 17. This epicenter is at the fifth node (72 degrees) from the M 8.1 in the Alaska Peninsula of July 29 and was probably promoted by energy from that source." (November 17-18, 2021)

An earthquake of M 5.9 also occurred in Guatemala today. NEIC reported this earthquake was felt with intensity V in Guatemala at Tiquisate; IV in Iztapa, Villa Canales, Santa Catarina, Villa Nueva and San Jose Pinula with lesser shaking at Guazacapan, San Miguel, Antigua Guatemala, and Santa Catarina Pinula.

Aftershocks of M 4.7 and 4.5 were also felt lightly in Guatemala in Antigua Guatemala and Mejicanos, San Salvador, El Salvador. The last earthquake of M>=6 in Guatemala and within about 150 km of today's epicenter occurred on May 30, 2019 with M 6.6. Four earthquakes of M 5.8-5.9  have hit the region in the past two years, the last of which was an M 5.9 about 100 km to the southeast on May 12, 2021. Today's activity occurred within about one hour of local solar noon, and was probably promoted by high tidal stresses associated with today's full moon and eclipse. Forecasts 138651 and 138654 had expected today's activity in Guatemala was likely around November 18-19.

The strongest earthquake in the U.S. or Canada today was an M 5.2 in the Andreanof Islands, Aleutians, Alaska. It was reported by NEIC to have been felt with intensity II in Adak, Alaska. The last earthquake within about 200 km of this epicenter occurred about 100 km to the west of today's epicenter on September 24, 2021 with M 6.1. It occurred near local solar midnight and was probably promoted by the new moon tidal stresses today. At the time of the September event its coincidence with the full moon was emphasized as:

 

"Note that this epicenter is at the exact longitude where tidal stresses were expected to maximize with this full moon. The Andreanof Islands earthquake today is the strongest in that region since an M 5.6 on February 19, 2021 and an M 6.1 on January 3, 2021 - the only such activity in the past year." (September 24-25, 2021)

 

Forecast 138796 had expected today's event in this area was likely around November 15.

The strong eruption of Cumbre Viejo, La Palma, Canary Islands, Spain continued at high levels today with major lava production  in this two-month eruption. The strongest earthquake in the area today was an M 4.8, the second strongest of the eruption - an M 4.9 occurred on November 3. The M 4.8 today occurred within several minutes of local solar midnight and was probably promoted by the full moon and eclipse today. Forecast 138412 expected this activity in the Canary Islands was likely to continue in mid-November.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

DEEP FOCUS QUAKE SHAKES ARGENTINA; MODERATE QUAKE IN SAN FRANCISCO, CALIFORNIA

 

EARTHQUAKE SUMMARY FOR NOVEMBER 17, 2021

 

Global and regional seismicity was at considerably higher levels today. While no strong earthquakes were recorded, moderate and widely felt earthquakes occurred in many areas including an M 4.0 in San Francisco, California and an M 5.5 under Central Argentina. This activity is probably related to tidal stresses associated with the full moon and lunar eclipse coming tomorrow and the two-day geomagnetic storm current in progress. These had been previously noted in this summary as:

 

"The full moon will arrive at 08:58 UT on November 19, 2021. Longitudes which area sub-solar at this time are located at sub-solar (local solar noon) at this hour near 45 East in the east  and at local solar midnight at 135 West longitude.  This continues the likely tidal triggering with the new Moon of November and in the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 16-23, 2021). This is a partial lunar eclipse, the longest of the century and will continue for up to 3.5 hours. In North America it is likely to cast a red rusty glow on the moon. Since the sun-earth-moon alignment is nearly exact during eclipses this will likely increase the intensity of tidal stresses and related seismicity near the time of the eclipse." (November 16-18, 2021)

 

and

 

"The geomagnetic field saw disturbed conditions today. The AP level was 12.  High latitude geomagnetic field also saw disturbed conditions with AP 18. This continues the moderate geomagnetic disturbance which began November 16 and could bring enhanced seismicity near the geomagnetic equator or at high latitudes in the next couple of days." (November 17-18, 2021)

 

A moderate earthquake of M 3.9-4.0 shook most of the San Francisco, California area today. It was reported by NEIC with intensity IV in Danville, San Ramon, Diablo, Castro Valley, Dublin, Castro Valley, Alamo and Clayton among others. An aftershock in the San Francisco Bay area of California of M 2.7 was felt with intensity II-III in Danville, San Ramon, Dublin, Castro Valley, Pleasanton, Walnut Creek and Boraga among others. The press reported only minor damage was associated with this earthquake and there were no reported major damage or casualties. This earthquake occurred within minutes of local solar noon, a time when tidal stresses maximize and was probably promoted by these stresses. It is also located near the longitude of maximum stress with the current full moon (see above). It is also near the antipode of an M 6.0 which occurred in the southern Indian Ocean on November 15. This summary had noted this relation (the Indian Ocean quake was at 37.6S, the San Francisco quake at 37.8N) when the Indian Ocean occurred as:

 

"A strong earthquake M 6.0 also occurred today in the southwest Indian Ridge directly south of the Iranian epicenters.  It was preceded by an M 5.3 foreshock and followed by aftershocks of M 4.5 and 4.7. None of this activity was reported felt in this remote area. The first of these occurred near local solar midnight and may have been promoted by high tidal stresses which maximize near this hour.

The antipode of this activity is off the coast of San Francisco, Central California and could help promote enhanced seismicity in that region of California in the next several days." (November 15, 2021)

 

Today's event in San Francisco also occurred near the height of the current geomagnetic storm and may have been promoted by stresses associated with that.

 

The last earthquake of larger magnitude than M 3.9 in the area of San Francisco was an M 4.5 on October 15, 2019 and an M 4.3 on July 16, 2019. An earthquake of M 3.9 hit near this epicenter on June 29, 2021. Forecast 138703 had expected today's activity within about 10 km was likely around November 15. This epicenter is at 102-103 degrees from the M 7.2 in the Mindanao, Philippines of August 11 and was probably promoted by energy from that source.

The largest earthquake felt in the U.S. or Canada today was an M 4.0 in southeastern Missouri. NEIC reported it was felt with maximum intensity V in Missouri at Poplar Bluff, Fairdealing, and Fisk, Holcomg, Clarkton, Neelyville, Oxly with IV in Williamsville, Ellsinore, Grandin, Wappapello, and II-III in Mill Spring, Greenville, and Broseley. It was also felt lightly throughout most of the southern United States as far as New Mexico and Florida with moderate shaking in Mississippi, Arkansas, Kentucky, Tennessee, Indiana, Illinois.

This is the strongest earthquake in Missouri within about 100 km of this epicenter since an M 4.2 more than 27 years ago on February 5, 1994. The only other event of M>=4 in the region in the past 30 years of similar magnitude was an M 3.9-4.0 on April 2, 2015 about 150 km southeast of today's epicenter. Forecasts 138718 and 138719 had expected today's activity within about 100 km was likely in mid-November. This epicenter is at 102-103 degrees from the M 8.2 in the Kermadec Islands of March 4 and was probably promoted by energy from that source.

A deep focus earthquake of M 5.5 occurred under Santiago del Estero, Argentina today. NEIC reported it was felt with intensity II in Santiago del Estero, San Pedro, Jujuy, and Buenos Aires, Argentina and in Santiago, Chile. The last earthquake within about 300 km of today's epicenter occurred as an M 6.0 pm December 24, 2019. Earthquakes of M 5.5-5.6 hit in this region on January 23, 2020 and March 25, 2018. Forecast 138853 had expected today's event within about 50-100 km was likely around November 15. This event is located at 103 degrees from the M 7.2 in Vanuatu of early October and was probably promoted by energy from that source.

An earthquake of M 3.9 shook the U.S. Virgin Islands today. NEIC reported it was felt with intensity II in Saint Thomas, Virgin Islands. This continues a series of similar earthquakes over the past two months. The only one of significantly larger magnitude in the Virgin Islands in this time period was an M 4.8 in southern Puerto Rico on October 8, 2021. An M 4.4 also occurred on June 18 in the Virgin Islands. This is near the antipode of a moderate earthquake in Western Australia of M 5.3 on November 13 as noted at the time of that event in this summary:

 

"Today's event in Australia follows a series of moderate earthquake in the region of Puerto Rico, the Dominican Republic and Haiti including an M 4.9 yesterday. Some additional enhancement may be seen in this area in the next several days." (November 13-14, 2021)

 

Forecast 138657 had expected today's seismic enhancement was likely in this area around November 17.

The strongest earthquake in the world today outside the America's was an M 5.2 in the area of New Ireland. This event was probably promoted by the current geomagnetic storm as it lies near the geomagnetic equator. This region including Indonesia as seen a series of strong earthquake associated with the previous geomagnetic storm and could see another strong event in this region with the current geomagnetic storm. Forecast 138630 had expected this event within about 150 km was likely around November 17. This epicenter is at the fifth node (72 degrees) from the M 8.1 in the Alaska Peninsula of July 29 and was probably promoted by energy from that source.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

UNUSUAL QUAKE SHAKES EASTERN CHINA

 

EARTHQUAKE SUMMARY FOR NOVEMBER 16, 2021

 

 

An unusual earthquake of M 5.0 occurred today in the Yellow Sea of China. NEIC reported maximum intensity V in Jiangsu with lesser shaking in Shanghai, China.  This is the strongest earthquake within about 300 km of this epicenter since an M 5.6 about 300 km to the southeast of this epicenter on November 9, 1996. It is the strongest event within about 200 km of this epicenter since an M 5.5 about 200 km to the north occurred on January 22, 1992. Forecast 138470 had expected today's event to the northwest was likely in early November. This epicenter is at 146 degrees from the M 8.2 in the South Sandwich Islands of August 12, 2021 and may have been promoted by energy from that source.

The earthquake in the Yellow Sea occurred shortly after an M 5.2 in Taiwan to the south of this epicenter. CWB reported this earthquake was felt with intensity III in Yilan and Hualien, II in Taipei, Taoyuan, Hsnichu, Taichung, Nantou, Keelung, and I in Hsinchu, Miaoli, Changhua, Yunlin, Chiayi Counties, Taiwan. This was the strongest earthquake located in the world today. Forecasts 138687 and 138691 had expected today's earthquake in Taiwan was likely in mid-November.

An earthquake of M 3.9 followed an M 4.0 in Hawaii today. NEIC reported these events were felt with intensity II-III in Hawaii in Naalehu, Captain Cook, and Kailua Kona. These followed an M 3.8 earlier in the day which NEIC reported was felt with maximum intensity IV in Pahala and II-III in Naalehu, Hawaii National Park, Captain Cook Volcano, Mountain View, Hilo, Kealakekua, Keaau and Paauilo. The strongest of these occurred within minutes of local solar midnight, a time when tidal stresses maximize and was likely promoted by tidal stresses. The last  earthquake in the current eruption of Kilauea Volcano of M>=4 was an M 4.3 aftershock of an M 6.2 on October 10, 2021. Forecast 138655 had expected today's activity was likely around November 17.

The strong eruption of Cumbre Viejo, La Palma, Canary Islands continued with elevated intensity today. Strong lava eruption threw lava and bombs high into the air. This eruption which has been occurring for at least two months, appears to be intensifying with more damage likely before the eruption ceases. The largest earthquake in this area today was an M 4.2 but the number of events of lesser magnitude was up considerably over the last several days. Forecast 138412 had expected continued enhanced seismicity in this area in mid-November.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG QUAKES DEADLY, DAMAGING IN SOUTHERN IRAN

 

EARTHQUAKE SUMMARY FOR NOVEMBER 14, 2021

 

Strong earthquakes occurred today in southern Iran. These events of M 6.3 and 6.4 (Iran Seismological Center)  were strongly felt in Iran. NEIC reported the mainshocks were felt with intensity VI in Bandar Abbas; VI in Gheshm, Minab; V in Giroft, IV in Hasab,  Bam, Iran and in Khawr Fakkan, United Arab Emirates and lesser intensity in Ras Al Khaiman and Uyman, UAR. Aftershocks of M 4.6 were also felt lightly. These events were felt in the countries of Bahrain, Saudi Arabia, Iran, Oman, Pakistan, Qatar, Afghanistan and the United Arab Emirates. They were located in the Hormozgan Province, Iran. This area saw several foreshocks yesterday and were noted in this summary as:

 

 

"Moderate earthquakes of M 4.3 and 4.6 occurred in southern Iran today. These were lightly felt in their epicentral areas. The M 4.6 occurred within minutes of local solar midnight and the M 4.3 was near local solar noon suggesting either tidal or geomagnetic triggering which is maximized at this hour. These events occurred near the longitude of maximum tidal  stress with the last new moon as noted in previous issues of this summary:

 

"The new moon will arrive at 21:15 UT on November 4. Longitudes which are near local solar midnight are located near 45 East while those at local solar noon with this new moon are near 135 West longitudes. In the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 1-7, 2021)." (November 1-9, 2021)

 

Forecast 138688 had expected this enhanced activity was likely in mid-November within about 100 km of these epicenter. Stronger activity in the area is possible in the next several days." (November 13-14, 2021)

 

The mainshocks today were reported by Reuters News to have killed at least one person, who was struck by a falling electric pole during the quake, and to have injured at least 47 on first report. Many buildings were destroyed in the quake.

 

The last earthquake in this area of Iran within about 300 km of this epicenter occurred about 350 km to the northeast of this with M 6.6 near Bam, Iran on December 26, 2003. Earthquakes of larger size also occurred with M 6.6 on March 4, 1999; March 14, 1998 and November 6, 1990. Forecast 138688 had expected today's activity within about 100 km was likely around November 15. This activity is located the fourth node (90 degrees) from the activity in the Alaska Peninsula of July 27, 2021; at 147 degrees from the M 7.2 in Mexico of September 8, 2021 and at 107 degrees from the M 8.1 in the South Sandwich Islands of August 12 and may have been promoted by energy from those sources.

A strong earthquake M 6.0 also occurred today in the southwest Indian Ridge directly south of the Iranian epicenters.  It was preceded by an M 5.3 foreshock and followed by aftershocks of M 4.5 and 4.7. None of this activity was reported felt in this remote area. The first of these occurred near local solar midnight and may have been promoted by high tidal stresses which maximize near this hour.

The antipode of this activity is off the coast of San Francisco, Central California and could help promote enhanced seismicity in that region of California in the next several days. The only earthquake of larger magnitude within about 300 km of this epicenter which has seen an earthquake of M>=6 in the past 30 years saw an event of M 6.2 on January 11, 2004.  Forecast 138875 had expected activity in this region was likely around November 14, 2021. This epicenter is located at 101-102 degrees from the M 7.2 in Vanuatu of October 2, 2021 and at the seventh node (51 degrees) from the M 8.1 in the South Sandwich Islands of August 14, 2020 and may have been promoted by energy from those sources.

The strongest seismicity near the U.S. or Canada today continued in the northern Gulf of California. This continue elevated seismicity in the region which began in early November. The strongest earthquake in this series today was an M 4.5. Two other earthquakes of M>=4.5 have occurred in this swarm - both of M 4.5 on November 3 and 5. This is the largest magnitude in this area in at least a year. Forecast 138721 had expected enhanced seismicity in this area was likely between November 12 and 16.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE EARTHQUAKE SHAKES WESTERN AUSTRALIA

 

EARTHQUAKE SUMMARY FOR NOVEMBER 13, 2021

 

An earthquake of M 5.3 was widely felt in northwestern Australia today. NEIC reported maximum intensity IV in Port Hedland, and II-III in Roebourne, Karratha, Broome, Geraldton and Albany, Western Australia. This is the strongest earthquake within about 300 km in at least 30 years. The only regional earthquake of larger magnitude in this time occurred about 350 km to the northeast of this with M 6.6 on July 14, 2019. At the time this summary noted in this regard:

 

"A strong M 6.6 earthquake was located off the coast of western Australia today.

NEIC reported it was felt with maximum intensity V in Broome, and IV in Port Hedland. Karratha and Darwin, Western Australia and within about 1500 km of the epicenter. This is an area where strong tropical cyclones often make landfall in Australia. This summary has previously linked these events to increased antipodal seismicity in the northern Caribbean. Today's event is antipodal to the Virgin Islands and Puerto Rico." (July 14, 2019)

 

Today's event in Australia follows a series of moderate earthquake in the region of Puerto Rico, the Dominican Republic and Haiti including an M 4.9 yesterday. Some additional enhancement may be seen in this area in the next several days. Today's epicenter in Australia is located at the seventh node (51 degrees) from the M 7.2 in Vanuatu of October 2 and 103 degrees from the M 8.2 in the Alaska Peninsula of July 29 and was probably promoted by energy from those sources.

Moderate earthquakes of M 4.3 and 4.6 occurred in southern Iran today. These were lightly felt in their epicentral areas. The M 4.6 occurred within minutes of local solar midnight and the M 4.3 was near local solar noon suggesting either tidal or geomagnetic triggering which is maximized at this hour. These events occurred near the longitude of maximum tidal stress with the last new moon as noted in previous issues of this summary:

 

"The new moon will arrive at 21:15 UT on November 4. Longitudes which are near local solar midnight are located near 45 East while those at local solar noon with this new moon are near 135 West longitudes. In the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 1-7, 2021)." (November 1-9, 2021)

 

Forecast 138688 had expected this enhanced activity was likely in mid-November within about 100 km of these epicenter. Stronger activity in the area is possible in the next several days.

A series of moderate-sized earthquakes also occurred under the Atlantic Ocean today. These were located at epicenters symmetric with the equator with an M 4.9 in the northern Mid-Atlantic in the Reykjanes Ridge and in the south with two of M 5.1 in the South Sandwich Islands (at 57.8N and 57.8S respectively). A series of moderate earthquakes also occurred in the Southern Mid-Atlantic with M 5.2, 5.2 and 5.0. The largest of these - the M 5.2 in the Southern Mid-Atlantic occurred within minutes of local solar midnight and was probably promoted by high tidal stesses which maximize near this hour. Forecasts 138883 had expected this activity around November 12. The event in the Reykjanes Ridge had been anticipated in forecast 138806 to occur within about 50 km of this epicenter around November 17. The quakes in the South Sandwich Islands was within about 100 km of that expected in forecast 138886 which was expected around November 15. The event in the southern mid-Atlantic Ridge was at the fifth node (72 degrees) from the Haiti M 7.2 of August 14, 2021 and may have affected by energy from that source.

The strongest seismicity near the U.S. or Canada continued today in the swarm in the northern Gulf of California. Events of M 4.3, 4.1 and 4.1 were registered in this area today. This swarm has been ongoing since the major X-flare and following geomagnetic storm of early November. Forecast 138731 had expected today's activity was likely within about 10 km around November 12.

A light earthquake hit the region of Los Angeles, California today with M 2.1

EMSC reported this earthquake of M 2.1 in Los Angeles, California was felt with intensity II-III in the area(s) of California a San Dimas, Duarte,   NEIC reported intensity II-III in Ponoma, San Dimas, Walnut, La Verne and Diamond Bar, California. This earthquake occurred simultaneously with the beginning of solar flare 4800 of C1.2. This was the strongest solar of the day. Earthquakes which are triggered instantly by Solar Flare Effects (SFE) can indicate epicenters which are at considerable stress and may be ripe for a larger earthquake in the near future. Forecast 138738 had expected this epicenter would likely be active around November 12.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE EARTHQUAKES SHAKE TURKEY AND HAITI

 

EARTHQUAKE SUMMARY FOR NOVEMBER 12, 2021

 

An earthquake of M 4.8 was widely felt in western Turkey today. NEIC reported this event was felt with maximum intensity VI in Turkey at Doganyol, Malatya and with IV in Cyprus with lesser shaking in Elazig, Turkey. The last earthquake within about 200 km of this epicenter with M>=4.8 occurred December 27, 2020 with M 5.5. The largest earthquake within about 100 km of this epicenter in the past two years was an M 5.6 on August 4, 2020. Today's event may be an aftershock of that earthquake. Forecast 138749 had expected enhanced seismicity in this area was likely in mid-November.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKES SHAKE MID-ATLANTIC IN ICELAND, SOUTHERN ATLANTIC

 

EARTHQUAKE SUMMARY FOR NOVEMBER 11, 2021

 

A series of three moderate earthquake shook the area under the Atlantic Ocean today. These occurred as an M 5.7 in the Southern Mid-Atlantic; an M 5.2 in Iceland and an M 5.3 and 4.6 in the South Sandwich Islands.

 

The strongest earthquake felt in the world today was an M 5.1 in southwestern Iceland. NEIC reported maximum intensity IV in Iceland at Vestmannaeyhar and Kopavogur with III in Hvolsvollur, Hella, Selfoss, Sudurland, Reykjavik and Grundarfjorfur. This event at a high latitude may have been promoted by the recent strong geomagnetic storm, one of the strongest in the past 15 years. It occurred where an ongoing volcanic eruption has been occurring for months and may change the nature of that eruption near Reykjavik. This is the strongest earthquake since an M 5.3 on March 14, 2021, part of an aftershock series of an M 5.6 on October 20, 2020 and February 24, 2021. This activity occurred about 150 km northwest of today's event. It was the first such activity in this area since an M 5.1 on January 8, 2015. Forecast 138823 had expected this event in this region was likely around November 13.

The strongest earthquake recorded today was an M 5.7 in the Southern Mid-Atlantic Ridge near the geomagnetic equator. It was probably enhanced by the recent geomagnetic storm and effects from tides as it occurred within  minutes of local solar midnight, a time when such tidal stresses maximize. This is the strongest earthquake within about 300 km of this epicenter in at least 30 years. A series of three events of M 5.7 hit the area about 300 km south of this in 2013, 2010 and 1999. Forecast 138883 had expected activity in this area with enhanced magnitude was likely around November 12 to the north.

A moderate earthquake of M 5.2 and 4.6 also occurred near local solar midnight in the South Sandwich Islands. This continues a strong swarm in that region which has been ongoing for more than a month. These earthquakes were not felt in the region. Forecast 138886 had expected today's activity was likely around November 15.

The strongest earthquake in the U.S. or Canada today was an M 3.9 in Southern Alaska. The last earthquake within about 100 km of this epicenter in Southern Alaska occurred as an M 4.0 on August 14, 2021. Similar events in the past year occurred on March 22 and February 18, 2021. Forecast 138546 had expected today's event around November 9 within about 50 km of this epicenter.

The largest earthquake in the vicinity of the U.S. or Canada today was an M 4.3 in the northern Gulf of California where a strong swarm has been occurring over the past week. This swarm has been gradually increasing over the past week. Earthquakes of M 4.5 and 4.3 occurred in the area on November 3 and 5. Forecast 138731 had expected enhanced seismicity in this area within about 10 km around November 12.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG QUAKES HIT RYUKYU ISLANDS, JAPAN, PAPUA NEW GUINEA

 

EARTHQUAKE SUMMARY FOR NOVEMBER 10, 2021

 

The strongest earthquake of the day today was an M 6.6 in the southern Ryukyu Islands east of Taiwan. NEIC reported maximum intensity IV in Okinawa at Hirara, and Ishigaki and II-III in Tomigusuku, Naha, Nishihara, Chatan, Okinawa, Hasbaru, Yomitan, and in Hualien, Taiwan. CWB reported today's event was lightly felt with intensity II in Changhua and I in Chiayi, Nantou, Yunlin, Taichung, Taitung, Taoyuan, Taipei, Yilan and Hualien Counties, Taiwan. This is the strongest earthquake in the world in the past month. An M 6.9 aftershock hit the Alaska Peninsula on October 11, 2021 and an M 7.3 and M 6.9 hit areas east of the Loyalty Islands an Vanuatu in early October, 2021. This summary had expected strong global activity around November 10 in previous issues as:

 

 

"... history suggests that a major earthquake is likely in the next several days. In general, strong geomagnetic storms see major earthquakes at the time of the storm's commencement or about 4-5 days later as the ionospheric ring currents at high latitude and about 10 degrees from the geomagnetic equator reemerge after the disturbance. This often includes a strong to major  earthquake. At this time such an event appears most likely near the geomagnetic equator or at high latitudes around November 8-10, 2021." (November 5, 8, 2021)

 

and

 

"While many areas are subject to geomagnetic and solar flare triggering, the most likely areas to see a strong quake at this time should be near solar noon or local solar midnight at the time of sudden commencement or shortly after strong X-flares. Areas that consistently trigger with major geomagnetic storms include Indonesia and Japan, Peru and northern Chile, Greece and Turkey  and occasionally the western edge of the North American tectonic plate." (October 29, 2021)

 

To date, areas which has shown strong or major earthquakes since the geomagnetic storm began included Peru, Turkey, Indonesia and Japan. These areas may continue to see enhanced seismicity in the next two days." (November 9-10, 2021)

 

 

This is the first earthquake within about 200 km of this epicenter in the area southeast of the Ryukyu Islands in at least 30 years. Earthquakes about 400 km to the northeast  and about 300 km to the southwest of this epicenter occurred on February 25, 2010 (M 7.0) and May 3, 1998 (M 7.5). Forecasts 138424 and 138687 had expected this activity was likely in early November. This epicenter is at the third node (120 degrees) from the M 7.2 in Mexico of September 8 and may have been promoted by energy from that source.

An earthquake of M 6.0 also occurred near the geomagnetic equator today in  the region of Papua New Guinea in Indonesia. This continues a series of earthquake of this size in Indonesia which has accompanied the recent geomagnetic storm. BMG reported this event with M 6.1 was felt with light to moderate intensity throughout much of southwestern New Guinea. This is the strongest earthquake within about 200 km of this epicenter since an M 6.6 on October 12, 2012

 more than nine years ago. Forecasts 138382 and 138643 had expected enhanced seismicity in this area in association with the geomagnetic storm was likely between November 4 and 12.

An earthquake of M 5.1 also occurred today in the North Mid-Atlantic Ocean near the Azores. NEIC reported it was felt with intensity II-III in the Azores at Horta and Angra. This may have been promoted by effects associated with the passage of Tropical Storm Wanda over the area in the past several days. Forecasts to the north of this occurred in the past three days as reported earlier in this summary:

 

Moderate earthquakes of M 5.0 and 4.1 hit the region of the Azores Islands, Portugal today. It was not reported felt in this remote area. It is likely that this event was triggered by the passage of Tropical Storm Wanda over this epicenter at the time of the earthquake. This had been noted in previous issues of this summary as a possibility as:

 

"TS    WANDA    2021-11-07  00:00 UT  40.2N   33.5W   40 kts  Central Northern Atlantic

 

Tropical Storm Wanda continued today in the central northern Atlantic with winds up to  40 kts. It is expected to track to the north over the next three days and not to greatly impact regional seismicity. Some enhanced seismicity may occur in the Northern Mid-Atlantic Ridge in association with this storm however." (November 6-9, 2021)

 

Forecasts 138452 and 138725 had expected these events were likely around November 12-14 within about 100 km of these epicenter.

The eruption of Cumbre Viejo volcano on La Palma, Canary Islands, brought new fears of a tsunami with that eruption today. Lava flows reached the sea and some lava was now eruption beneath the ocean. This could raise the possibility of a tsunami with this eruption as has been feared for some time. A tsunami could be generated by a massive flank eruption but is unlikely to have much impact in the Americas. The strongest earthquake in the Canary Islands associated with this eruption  today was an M 4.7, the strongest to date since an 4.9 on November 2 and events of M 4.7 on October 23 and October 26.

The strongest earthquake in the U.S. or Canada today was an M 4.7 in the Rat Islands, Aleutians, Alaska. It was not reported felt in this remote area. The last earthquake of larger magnitude in the Rat Islands was an M 5.1 on October 23, 2021 and this may be an aftershock of that event. Forecast 138810 had expected today's activity was likely around November 12 within about 100 km of this epicenter.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

QUIET DAY IN SEISMICITY MAY PRECEDE INCREASED ACTIVITY

 

EARTHQUAKE SUMMARY FOR NOVEMBER  9, 2021

 

It was a relatively quiet day in global seismicity today. The strongest earthquakes in the world today was an M 5.0 in Java, Indonesia. This event in Java is at the antipode of an M 4.3 in Northern Colombia. These may have been promoted by the geomagnetic storm which has now concluded. But the major triggering from this storm is still likely in the next day as noted in previous issues of this summary:

 

 

"... history suggests that a major earthquake is likely in the next several days. In general, strong geomagnetic storms see major earthquakes at the time of the storm's commencement or about 4-5 days later as the ionospheric ring currents at high latitude and about 10 degrees from the geomagnetic equator reemerge after the disturbance. This often includes a strong to major earthquake. At this time such an event appears most likely near the geomagnetic equator or at high latitudes around November 8-10, 2021." (November 5, 8, 2021)

 

and

 

"While many areas are subject to geomagnetic and solar flare triggering, the most likely areas to see a strong quake at this time should be near solar noon or local solar midnight at the time of sudden commencement or shortly after strong X-flares. Areas that consistently trigger with major geomagnetic storms include Indonesia and Japan, Peru and northern Chile, Greece and Turkey  and occasionally the western edge of the North American tectonic plate." (October 29, 2021)

 

To date, areas which has shown strong or major earthquakes since the geomagnetic storm began included Peru, Turkey, Nicaragua (on the western edge of the North American Plate0, Indonesia and Japan. These areas may continue to see enhanced seismicity in the next two days.

 

 

NEIC reported the earthquake of M 5.0 in Java, Indonesia was felt with intensity II-III in the area(s) of Java, Indonesia in Palabuhanratu (IV), Bogor, Depok, Tangerang (IV), Jakarta and Yogyakarta. The earthquakes south of Java were forecast in #138376 to occur within about 100 km in this area in early November. This epicenter is at 103 degrees from the M 8.2 in the South Sandwich Islands of August 12 and was probably promoted by energy from that source.

The strongest earthquake in the U.S. or Canada outside Alaska today was an M 3.6 off the coast of British Columbia, Canada. It was not reported felt in this remote area. The last event of M>=3.6 reported in this area by NEIC was an M 4.3 on December 25, 2020 and a year ago on November 11, 2020. Forecast 138527 had expected this event was likely around November 8 within  about 25 km of this epicenter.

An M 3.9 also occurred in the Fox Islands, Alaska today. It was not reported felt in this remote area. This is apparently an aftershock, the strongest  to date, of an M 5.2 which hit about 50 km from this epicenter on November 4. Forecast 138529 had expected today's event within about 100 km was likely around November 10.

The strong swarm in the northern Gulf of California also continued today. Maximum earthquake size in the area today reached M 4.1. This series began in earnest with the geomagnetic storm and has continued off and on throughout November, 2021. As in previous days, most of the larger events in this swarm today occurred near local solar midnight and noon and were probably promoted by tidal stresses which maximize near this hour. Forecast 138459 had expected today's activity which appears to be migrating to the southeast, around November 9.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG EARTHQUAKES SHAKE NICARAGUA

 

EARTHQUAKE SUMMARY FOR NOVEMBER  8, 2021

 

A series of moderately strong and strong earthquake rattled areas of Nicaragua

and Costa Rica today. The strongest of these was an M 6.2 which was felt with intensity VI in El Crucero, Managua and V in San Juan del Sur Rivas, Diriamba Carazo, Mandame, Granada, Nicaragua and in La Cruz Guanacaste, Costa Rica. It was also felt with intensity IV in Ticuantepe, Managua and III in El Jicaro, Nueva Segovia, San Rafael del Sur, Catarina Masaya and Granada, Nicaragua.

Foreshocks of M 5.8 and M 5.7 were similarly felt in Nicaragua with maximum  intensity VI in Rivas, and Dinamba Carazo, Nicaragua and V in Liberia, Guanacaste, Costa Rica. It is likely that the geomagnetic storm of the past several days helped trigger today's earthquakes in Nicaragua which is near the equator as reported  in previous issues of this summary:

 

"the geomagnetic storm, the strongest in the world since AP reached 76 on August 26, 2018. The last time high latitude AP exceeded 100 was September 8, 2017 when high latitude AP was 110. This geomagnetic storm was accompanied by the M 8.2 in eastern Mexico on the same date. Today's storm may enhance global seismicity for the next several days especially at high latitude and near the geomagnetic equator." (November 2-7, 2021)

 

and

 

"... history suggests that a major earthquake is likely in the next several days. In general, strong geomagnetic storms see major earthquakes at the time of the storm's commencement or about 4-5 days later as the ionospheric ring currents at high latitude and about 10 degrees from the geomagnetic equator reemerge after the disturbance. This often includes a strong to major earthquake. At this time such an event appears most likely near the geomagnetic equator or at high latitudes around November 8-10, 2021." (November 5, 2021)

 

 

It is also likely that this event was promoted by stresses associated with Tropical  Storm Terry (18E) as reported in previous issues of this summary:

 

"Tropical Depression 18E (Tropical Storm Terry) continued west of Costa Rica with winds up to 40 kts. This storm may enhance seismicity in Costa Rica and Panama as it moves away from that area." (November 2-6, 2021)

 

Reuters reported there was no major damage associated with today's earthquakes.

These epicenters are also located near the antipode of the last event of M 6.2 in the world - the M 6.2 in Nias, Sumatra, Indonesia of November 1, 2021 and may have been promoted by focused energy from that source.

 

An M 6.5 hit about 200 km northwest of today's epicenter on September 22, 2021, but the last event within about 200 km in Nicaragua was an M 6.6 on April 11, 2014. Forecast 138499 had expected today's activity within about 50 km was likely around November 7.  This event is located at 143 degrees from the

M 7.1 in Mindanao, Philippines of August 11, 2021 and may have been promoted by energy from that source.  It is also is located at the fifth node (72 degrees) from the M 8.2 in Alaska Peninsula of July 29 and at 102 degrees from the

M 7.2 in Vanuatu of October 2, 2021 and may have been promoted by energy from those sources.

A regional foreshock hit the area north of Nicaragua in the area off the coast of El Salvador with M 4.5 earlier in the day. This event occurred within minutes of local solar noon and was probably enhanced by tidal stresses which maximize near this hour. Forecast 138401 had expected today's event within  about 100 km was likely around November 5.

 

NEIC reported this earthquake of M 4.5 in El Salvador was felt with intensity II-III in the area(s) of El Salvador at Antiguo Cuscatlan, San Salvador and Seneuntepeque.

An earthquake of M 5.1 was also widely felt in Central Turkey today. NEIC reported it was felt with maximum intensity V in Turkey at Konya and IV in Seydisehir, Isparta, Antalya and II-III in Alanya, Incesu, Larnaca, Cyprus, Istanbul, and in Ahwaz and Tehran, Iran. This was probably promoted by high tidal stresses with the latest new moon. The seismic forecast for this new moon had placed the area of maximum stress near the longitude of today's event (32 East longitude) as:

 

"The new moon  arrived at 21:15 UT on November 4. Longitudes which were near local solar midnight are located near 45 East while those at local solar noon with this new moon are near 135 West longitudes. In the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 1-7, 2021)." (November 2-7, 2021)

 

A building in eastern Turkey in Malatya province collapsed about the time of this earthquake, but it is not expected to have been caused by shaking related to this event. Workers are searching the building for survivors. The last earthquake of M>=5.1 within about 200 km of today's epicenter was an M 5.3 about 200 km southwest of this epicenter on December 5, 2020. Forecast 138477 had expected seismic enhancement in Turkey east of this epicenter around November 8. This event is located at 144 degrees from the M 7.2 in Vanuatu of October 2, 2021 and may have been promoted by energy from that source.

The strongest seismicity near the U.S. or Canada today continued in the northern

 Gulf of California. Earthquakes of M 4.2, 4.1, 4.0 and 3.9 hit the area today slightly more powerful than the events yesterday. Much of this activity occurred near local solar noon and was likely promoted by high tidal stresses which maximize near this hour. Forecast 138459 had expected this seismic enhancement was likely around November 9.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKE IN SOUTH SANDWICH ISLANDS

 

EARTHQUAKE SUMMARY FOR NOVEMBER  7, 2021

 

An earthquake of M 5.1 occurred today in the South Sandwich Islands at a high latitude. It was probably promoted by the current geomagnetic storm. It was not reported felt in this remote area. This was the strongest earthquake located in the world today. But seismic enhancement is expected near the geomagnetic equator and at high latitudes in the next several days. Forecast 138607 had expected today's event was likely within about 100 km around November 9. This summary had expected high latitude seismic enhancement at this time as:

 

"The geomagnetic field saw disturbed conditions today. The AP level was 13.  High latitude geomagnetic field saw active conditions with AP 23. This continues the geomagnetic storm, the strongest in the world since AP reached 76 on August 26, 2018. The last time high latitude AP exceeded 100 was September 8, 2017 when high latitude AP was 110. This geomagnetic storm was accompanied by the M 8.2 in eastern Mexico on the same date. Today's storm may enhance global seismicity for the next several days especially at high latitude and near the geomagnetic equator." (November 5-7, 2021)

The strongest earthquake in the U.S. or Canada today was an M 3.5 aftershock  in Southern Idaho.  NEIC reported this earthquake of M 3.2-3.5 in Southern Idaho  as felt with intensity II-III in the area(s) of Southern Idaho at Stanley.  Earthquakes of this size are not uncommon in the aftershock zone of the M 6.5 of March 31, 2020, the last such event was an M 3.6 on November 4. Forecast 138494 had expected enhanced seismicity in this area was likely around November 7.

A moderate earthquake of M 4.1 hit the region of the Azores Islands, Portugal today. It was not reported felt in this remote area. It is likely that this event was triggered by the passage of Tropical Storm Wanda over this epicenter at the time of the earthquake. This had been noted in previous issues of this summary as a possibility as:

 

"TS    WANDA    2021-11-07  00:00 UT  40.2N   33.5W   40 kts  Central Northern Atlantic

 

Tropical Storm Wanda continued today in the central northern Atlantic with winds up to  40 kts. It is expected to track to the north over the next three days and not to greatly impact regional seismicity. Some enhanced seismicity may occur in the Northern Mid-Atlantic Ridge in association with this storm however." (November 6-7, 2021)

An earthquake of M 4.3 also shook the region of Haiti today and was accompanied by a series shocks of M>-3.4. This is the strongest aftershock of the M 7.2 of August 14, 2021 in Haiti since mid-August. Forecast 138410 had expected today's event within about 15 km was likely around November 6.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG EARTHQUAKE IN MOLUCCA SEA, INDONESIA

 

EARTHQUAKE SUMMARY FOR NOVEMBER  6, 2021

 

The strongest earthquake in the world today was an M 6.0-6.2 in the Molucca Sea, Indonesia. NEIC reported it was felt with maximum intensity VI in Sulawesi at Mobagu with V in Gorantalo, IV in Tomohon, and Poso, Sulawesi and III in Manado, and Luwuk, Sulawesi. BMG reported this earthquake with M 6.2 was felt with intensity IV-V in Bolaang Mongondow Timur; III-IV in Kotamobagu, III in Bolaang Mongondow, Talibu, Gorontalo, Bitung and II-II in Manado and Tomohon, Molucca, Indonesia. This continues a series of strong earthquakes in Indonesia which began with the major geomagnetic storm which continued today. This summary had noted this storm as:

 

"The geomagnetic field saw disturbed conditions today. The AP level was 13.  High latitude geomagnetic field saw active conditions with AP 23. This continues the geomagnetic storm, the strongest in the world since AP reached 76 on August 26, 2018. The last time high latitude AP exceeded 100 was September 8, 2017 when high latitude AP was 110. This geomagnetic storm was accompanied by the M 8.2 in eastern Mexico on the same date. Today's storm may enhance global seismicity for the next several days especially at high latitude and near the geomagnetic equator." (November 5-7, 2021)

 

The last earthquake in the Molucca Sea within about 200 km of today's epicenter

with M>=6 was an M 6.1 on January 19, 2020. The last of significantly larger magnitude was an M 6.8 about 200 km southwest of today's epicenter on April 12, 2019, Forecast 138380 had expected today's activity to the southwest was likely around November 3.

A moderate earthquake of M 5.2-5.5 was also felt around Cook Strait, New Zealand today. NEIC reported maximum shaking IV in Picton, South Island with II-III in Tankaka, Matueka, Opunake, Nelson, Richmond, Kapanga, Stratford, Blenheim and Wanganui. GEONET reported this earthquake was felt with moderate intensity in Cook Strait and Southern North Island. 13109  people reported feeling this event; 6407 with weak intensity; 5709 with light shaking; 916 moderate; 50 strong; 2 with severe and 15 with extreme shaking. An M 4.8 hit the Cook Strait on October 12, 2021, the largest in the area in the past year. The last earthquake in the Cook Strait area of M>=5.2 was an M 5.6 on May 24, 2020 and prior to that an M 5.4 on January 5, 2017. Forecast 138602 had expected today's activity was likely in early November.

A series of moderate earthquakes of M 5.4 occurred at high latitudes and near the geomagnetic equator today. These were probably promoted by the ongoing geomagnetic storm. They occurred at a high latitude in the South Sandwich Islands at a somewhat unusual epicenter. Several events of M 5.4 also occurred near the geomagnetic equator in Tonga and Fiji as well as the M 6.0-6.2 in Molucca, Indonesia. ,

 

The earthquake in the South Sandwich Islands of M 5.4 is the strongest since an M 5.5 on August 29, 2021. These are aftershocks of an M 6.9 at this epicenter on August 16, 2021. Forecast 138607 had expected enhanced seismicity in this area in early November.

 

NEIC reported the earthquake of M 5.3 in Tonga was felt with intensity II-III in the area(s) of Tonga at Ohonua Eua.

The earthquakes of M 5.4 and 5.4 in the eastern Tonga Islands are also located near the geomagnetic equator. The last such activity in Tonga of equal or greater  magnitude occurred October 19 (M 5.6) and September 20, 2021 (M 5.8).  These events had been expected in this area by forecast 138586 within about 150 km in early November.

An unusual earthquake of M 2.5 shook areas of Alabama, Mississippi and Georgia (U.S.) today. NEIC reported maximum intensity IV in Eutaw, Alabama and Biloxi, Mississippi with lesser shaking in Gainesville and Carrolton, Alabama and in Rome and Marietta, Georgia.  An earthquake of M 2.6 last occurred within about 100 km of this epicenter on October 15, 2020. Forecast 138211 had expected enhanced regional seismicity in this area in late October or early November.

The strongest activity near the U.S. or Canada today continued in the northern Gulf of California. The largest of these, an M 3.9 occurred within minutes of local solar midnight and was probably promoted by high tidal stresses which maximize near this hour. Forecast 138459 had expected today's activity was likely to continue in early November.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

MODERATE QUAKES CONTINUE NEAR GEOMAGNETIC EQUATOR

 

EARTHQUAKE SUMMARY FOR NOVEMBER  5, 2021

 

A moderate earthquake of M 5.2 occurred in northern Peru near the geomagnetic equator today. NEIC reported it was felt with intensity IV in Pura, Peru at Sechura, Paita, Suilana, Pura and II-III in La Union, Santa Rosa, Jaen, San Luis and Mala, Lima. This is the strongest earthquake in this seismic transition period of the day. This is the strongest earthquake within about 200 km in northern Peru since an M 5.2 on March 7, 2019. The last such event of larger magnitude was an M 5.3 on April 2, 2017. The last of significantly larger magnitude in the area was an M 6.3 on March 15, 2014. Forecast 138372 had expected today's activity to the east was likely in northern Peru around November 6.

The region of Indonesia took a break from strong seismicity today. Moderately strong to strong earthquakes have hit the area daily since the current geomagnetic storms began. The region is located near the geomagnetic equator and is ideally located to experience strong seismic triggering with flares and

 geomagnetic storms. The strongest earthquake in the area today was an M 5.1 in Sulawesi. This activity had been expected in forecast 138347 around November 5.

 

NEIC reported this earthquake of M 5.1 in Sulawesi, Indonesia was felt with intensity II-IV in the area(s) of Poso and Palu, Sulawesi, Indonesia.

An unusual earthquake of M 4.6 was felt today in the area of Mozambique. NEIC reported maximum intensity IV in Chimolo Manica and Beira Sofala, Mozambique and II-III in Zimbabwe at Mutare and Mufoko. This is the strongest earthquake within about 200 km of this epicenter in Mozambique since an M 5.4 on December 22, 2018 and an M 5.6 on June 24, 2017. Forecast 138582 had expected today's event within this area was likely around November 10. This epicenter is at 144 degrees from the M 8.2 in the Alaska Peninsula event of July 29 and was probably promoted by energy from that source.

The swarm of earthquake in the northern Gulf of California continued today with increased intensity. The largest events in the region today occurred near local solar noon with M 4.6 4.5, 4.2 and 4.3 and with an M 4.3 near local solar midnight. These may have been promoted by the strong geomagnetic storm yesterday and the new moon tidal stresses of November 4. The last event in this region of larger magnitude occurred with M 5.2 on April 6, 2019. Forecast 138459 had expected enhanced seismicity in the area with events up to M 4.6 was likely around November 4.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONGEST HIGH LATITUDE GEOMAGNETIC STORM IN 15 YEARS MAY BRING STRONG EARTHQUAKES

 

EARTHQUAKE SUMMARY FOR NOVEMBER  4, 2021

 

The expected major geomagnetic storm occurred today. This was noted in this

and previous summaries as:

 

"The geomagnetic field saw severe storm conditions today. The AP level was 69.  High latitude geomagnetic field also saw severe storm conditions with AP 131. This geomagnetic storm, the strongest in the world since AP reached 76 on August 26, 2018. The last time high latitude AP exceeded 100 was September 8, 2017 when high latitude AP was 110. This geomagnetic storm was accompanied by the M 8.2 in eastern Mexico on the same date. Today's storm may enhance global seismicity for the next several days especially at high latitude and near the geomagnetic equator." (November 4-5, 2021)

 

The last time high latitude AP exceeded 120 was on December 15, 2006 when it hit AP 120 with global AP at 104. The earthquake in 2006 was followed several days later by an M 7.0 in Taiwan. The last time the AP disturbance at high latitudes exceeded today's index of 131 was on September 11-12 (AP 131 and 136). The storm in September, 2005 was accompanied by an M 7.7 in New Ireland and an M 6.4 in the Nias region of Indonesia. This history suggests that a major earthquake is likely in the next several days. In general, strong geomagnetic storms see major earthquakes at the time of the storm's commencement or about 4-5 days later as the ionospheric ring currents at high latitude and about 10 degrees from the geomagnetic equator reemerge after the disturbance. This often includes a strong to major  earthquake. At this time such an event appears most likely near the geomagnetic equator or at high latitudes around November 8-10, 2021.

 

Today's geomagnetic storm reached maximum of Kp 8-9 around 09:00 and 16:00 UT. Maximum index for Kp is 9-10 so this is among the strongest geomagnetic storms likely at any time.

 

The strongest earthquake in the world today was an M 5.5-5.9 off the west coast of South Island, New Zealand. NEIC reported it was felt with intensity II in Invercargill, Southland. GEONET reported this earthquake was felt by 19 people, 13 with weak shaking and 6 with light intensity. This event appears to have been triggered by the geomagnetic storm which was near it's maximum at the time it occurred. The last event of M>=5.5 within about 200 km of today's epicenter was an M 5.8 on November 24, 2018 while the last of M>=5.9 was an M 6.6 on July 11, 2017. Forecast 138603 had expected enhanced seismicity in this area in early November. This earthquake, like an M 4.9 in western Honshu, Japan is located at 103-105 degrees from the M 7.1 in Guerrero, Mexico of September 8, 2021 and was probably promoted by energy from that source.

The second strongest earthquake of the day was an M 5.3 in the Maug Islands of northern Marianas. This appears to be an aftershock of an M 5.5 which hit the area on June 21, 2021. This earthquake occurred at the height of the geomagnetic storm today and is located near the geomagnetic equator and was probably promoted by that storm. Forecast 138402 had expected today's event in the northern Marianas was likely around November 3.

An earthquake of M 4.5 was felt in Colombia today. NEIC reported it was felt with maximum intensity IV in Colombia at Tumaco and II-III in Barbacoas, and Popayan. This epicenter is near the antipode of the M 6.1 in Nias, Indonesia of November 1 and was probably promoted by focused energy from that source. Forecast 138351 had expected this activity in early November.

The strongest earthquake in the U.S. or Canada today was an M 5.2 in the Fox Islands, Aleutians, Alaska. NEIC reported it was felt with intensity II in Alaska at Unalaska and Atka. This earthquake occurred near local solar midnight as the geomagnetic storm commenced at high latitudes. It is likely it was triggered by effects from that storm. The last earthquake of M>5.2 in the Fox Islands within about 200 km of this epicenter occurred nearly a year ago on December 1, 2020 following an M 5.5 the day before on November 30, 2020. Forecast 139530 had expected today's earthquake in the Fox Islands was likely around November 4.

An M 4.7 also occurred in the Alaska Peninsula aftershock zone and accompanied the maximum of the geomagnetic storm. It is likely it was triggered by effects from that storm. This is the strongest aftershock within about 200 km to date of the M 6.9 which occurred at this epicenter on October 11, 2021 - itself an aftershock of the M 8.2 on July 29, 2021. Forecast 138522 had expected today's event was likely around November 6.

The strongest earthquakes near the U.S. today outside Alaska continued in the northern Gulf of California. In the previous issue of this summary it had been reported in this regard:

 

 

“Much of today's strongest activity occurred near local solar midnight and local solar noon and may have been promoted by strong tidal stresses with the new moon  as described in this and previous issues of this report:

 

"The new moon will arrive at 21:15 UT on November 4. Longitudes which are near local solar midnight are located near 45 East while those at local solar noon with this new moon are near 135 West longitudes. In the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 1-7, 2021)." (November 1-3, 2021)

 

Forecast 138459 had expected today's activity was likely within about 50 km around November 4. This area often also sees enhanced seismicity with strong geomagnetic storms and most of today's largest earthquakes occurred near the maximum of today's storm.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

SEISMIC ENHANCEMENT CONTINUES IN INDONESIA; CANARY ISLANDS

 

EARTHQUAKE SUMMARY FOR NOVEMBER  3, 2021

 

The strongest earthquake in the world today was an M 5.8 in Ceram, Indonesia. BMG reported it was felt with intensity V in Sawai; IV in Wahai; III in Ambon and Masohi and Saparua, Indonesia. This continues a strong activation of the region of Indonesia which has accompanied the current geomagnetic storm. Indonesia is located on the geomagnetic equator and is often activated during such storms. The last earthquake within Seram, Indonesia within about 200 km of today's epicenter with M>=5.7 occurred on June 15, 2021 and September 25, 2019 with M 5.9 and M 6,5 respectively.  Forecasts 138101 and 138365 had expected today's event within about 100 km was likely between October 27 and November 4.

A moderate earthquake of M 4.9 hit the Cumbre Viejo volcanic area of La Palma Island, Canary Islands today. This is the strongest earthquake in the Canary Islands in the current eruptions. The only earthquake in the Canary Islands with M>=4.9 in the past 30 years was an M 5.4 on December 27, 2013. The eruption continued with strong intensity with lava flows and eruptions. This eruption began in mid-September and continues at a higher level of activity than previously. Forecast 138412 had expected enhanced seismicity in the Canary Islands was likely around November 3.

The strongest earthquake in the U.S. or Canada today was an M 4.1 in Northern California. NEIC reported this earthquake of M 4.1 in Northern California was felt with intensity II-III in the area(s) of Northern California at Laytonville, Leggett, Covelo, Willits, Mendocino, Ukiah, Red Bluff, Anderson, Eureka and McKinley. The last earthquake with M>=4.1 within about 50 km of this epicenter was an M 4.2 about 50 km to the south on August 19, 2020 and an M 4.3 on April 29, 2019. The last - and only earthquake in the area in the past 30 years - of significantly larger magnitude in the area was an M 4.8 on April 18, 2007.

Forecast 138437 had expected today's activity within about 25 km was likely around November 5.

The swarm of moderate and light earthquakes continued today in the region of the northern Gulf of California. NEIC reported the largest event in this swarm to date, an M 4.5 which occurred today, was felt with intensity II in Puerto Penasco, Sonora, Mexico. The M 4.5 is the strongest earthquake in this swarm since an M 4.7 on April 1, 2021 and an M 5.2 on April 6, 2019. Activity in this area often increases with strong geomagnetic storms such as has been occurring over the past several days as described in this summary:

 

"The geomagnetic field saw active conditions today. The AP level was 21.  High latitude geomagnetic field saw disturbed conditions with AP 14. This geomagnetic storm, the strongest since AP reached 45 on October 12  may enhance global seismicity for the next several days especially at high latitude and near the geomagnetic equator.." (November 2-4, 2021)

 

Much of today's strongest activity occurred near local solar midnight and local solar noon and may have been promoted by strong tidal stresses with the new moon  as described in this and previous issues of this report:

 

"The new moon will arrive at 21:15 UT on November 4. Longitudes which are near local solar midnight are located near 45 East while those at local solar noon with this new moon are near 135 West longitudes. In the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 1-7, 2021)." (November 1-3, 2021)

 

Forecast 138459 had expected today's activity was likely within about 50 km

around November 4.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

The strongest earthquake in the U.S. or Canada today was an M 4.4 in the area off the coast of northern California. NEIC reported it was felt with maximum intensity IV in northern California at Ferndale, Rio Dell, Redcrest; II-III in Petrolia, Hydes, Fortuna, Carlotta, Loleta, Myers Flat and Eureka.

 

NEIC reported this earthquake of M 3.4 off the coast of Northern California  was felt with intensity II-III in the area(s) of Northern California in Rio Dell, Portuna, Loleta, Eureka, Penn Valley. This activity may have been enhanced by high tidal stesses associated with NEIC reported an aftershock of M 3.4 off the coast of Northern California  was felt with intensity II-III in the area(s) of Northern California in Rio Dell, Portuna, Loleta, Eureka, Penn Valley.  the coming new moon as noted in this and previous issues of this summary:

 

"The new moon will arrive at 21:15 UT on November 4. Longitudes which are near local solar midnight are located near 45 East while those at local solar noon with this new moon are near 135 West longitudes. In the east these include Turkey and Iran while in the west they include the west coast of North America including eastern Alaska and western Canada and oceanic areas west of Washington and Oregon States. These are the most likely areas to experience seismicity brought on by tidal stresses with this new moon. Other areas may also see tidal triggering but it is expected to be moderate during the next week (November 1-7, 2021). (November 1-3, 2021)

 

The last earthquake of significantly larger magnitude in this region off the coast of California was an M 5.1 on July 18, 2021 but similar events of M 4.4-4.5 occurred on July 21 and September 9, 2021. Forecasts 138503 and 138244 had expected today's activity in late October or early November.

Moderate earthquakes of M 4.0, 4.0, 4.0 and 4.3 also continued today in the northern Gulf of California and in Baja California. This continues activation of the area which accompanied the major solar activity of the past several days and the following geomagnetic storm which continued today. This activity had been noted on October 31 in this summary as:

 

"After several days of quiet, the series of moderate earthquake in the northern Gulf of California re-ignited today with at least 9 earthquake of M>=3.4 in the region today. This began within a few minutes of local solar midnight with an M 3.6 with a second series beginning at local solar noon, 12 hours later. This is an area which reacts strongly to solar flare effects and often shows enhanced seismicity in association with strong solar and geomagnetic storms and this is probably the case in this re-activation. The M 3.9 is the strongest event except for an M 4.4 on September 27, 2021 in nearly two years - since December 2019." (October 30, 2021)

 

Forecast 138459 had expected today's activity was likely around November 4.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.

STRONG EARTHQUAKE SHAKES NIAS, SUMATRA, INDONESIA

 

EARTHQUAKE SUMMARY FOR NOVEMBER 1, 2021

 

The strongest earthquake in the world today occurred on the equator in Nias, Indonesia. It was reported by NEIC to have been felt with maximum intensity IV in Guning Stoli, Sumatra and II-III in Sibolga, Banda Aceh. BMG gave this event M 6.2 and noted it was felt with intensity III-IV in Sumatra at Nias Barat, Nias Selatan, Mentawai,Nias Utara, III in Aceh Singkil, II-III in Gunung Sitoli and II in Pak Pak Barat. This event, on the equator, appears to have been promoted by the strong geomagnetic storm of the past day. This summary had expected such seismicity with this geomagnetic storm in previous issues as:

 

"The geomagnetic field saw minor storm conditions today. The AP level was 20.  High latitude geomagnetic field also saw quiet conditions with AP 24. This geomagnetic storm, the strongest since AP reached 45 on October 12  may enhance global seismicity for the next several days especially at high latitude and near the geomagnetic equator." (October 31-November 1, 2021)

 

The last earthquake of M>=6.2 within about 200 km of this epicenter was an M 6.6 on May 14, 2021 and an M 6.1 on April 19, 2021 following more than 13 years of quiet at this magnitude level (since 2008) in the area. Forecasts 138357 and 138096 had expected this activity in late October or early November. This earthquake is near 103 degrees from the M 8.2 in the South Sandwich Islands of August 12, 2021 and was probably promoted by energy from that source.

A moderate earthquake of M 5.0 shook the area of Anguilla, Leeward Islands in the northeastern Caribbean today. NEIC reported it was felt with intensity II-III in Anguilla; in Guadeloupe at Saint-Barthelemy, Marigot; in the Netherland Antilles at Golden Rock, Phillipsburg, Princess Quarter, Little Bay, Cul De Sac, Low Lands, Sint Maarten and in Codrington, Barbuda and Antigua. This is the strongest earthquake within about 150 km of this epicenter since an M 5.2 on February 9, 2018 and an M 5.2 on December 24, 2017. Forecasts 138392 and 139142 had expected this earthquake was likely between October 26 and November 5.

An earthquake of M 5.4 also shook the area between the Loyalty Islands and New Caledonia today. This continues a re-activation of the area which began October 31 with events of M 4.9-5.0  on October 31 and November 1, 2021. The last  earthquake of larger magnitude within about 150 km of this epicenter in the Loyalty Islands was an M 5.7 on June 23, 2021. These are regional aftershocks of the M 7.7 on February 10, 2021.  Forecasts 138578 and 138316 had expected this activity in late October or early November.

 

NEIC reported this earthquake of M 5.4 in the Loyalty Islands was felt with intensity II-III in the area(s) of the Loyalty Islands in Vanuatu at Isangel Tafea (IV).

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

For most events there are two listings. The first line is the observed event starting with "O:" for Observed. There follows the date, month and year, the time in UT hours:minutes:seconds, the latitude and longitude, the given magnitude and the reporting agency followed by the geographic location. The second line starts with "P:" This is the forecast event as forecast in our summaries normally more than a month in advance. Magnitudes may vary in response to updated seismic watches and daily variations due to tidal and other influences. This line has the forecast date, month and year, the forecast number, latitude, longitude and forecast magnitude range.  This is followed by a comparison between the forecast and the event. The comparison includes letters A-D. The first is number of days difference from predicted (A:up to 2, B3-5; C:6-10; D:more than 10), Difference in latitude (A:up to 1 degree; B:1-2 degrees; C:2-4 degrees; D:more than 4 degrees); longitude (same comparison as with latitude); magnitude (A: within forecast range; B: higher than forecast range; C: lower than forecast range; D: no comparison possible). The last letter is a stand in for a future comparison which needs to be done statistically after a large number of forecasts have been made. In previous data, an excellent match is generally AAAAA; a good match as one or two B's; a fair match has several B's and C's and a poor match is one which contains a number of C's or D's.
