STRONG QUAKES CONTINUE IN INDONESIA

 

EARTHQUAKE SUMMARY FOR NOVEMBER 14, 2023

 

The current seismic enhancement in Indonesia continued today with two strong earthquakes - an M 6.1 south of Sumatra and an M 5.9 in Papua New Guinea.

 

The strongest earthquake in the world today was an M 6.1 south of Sumatra and India in the South Indian Ocean. It was not reported felt in this remote area.

 

The earthquake in the South Indian Ocean of M 6.1 was not reported felt in this area. It occurred near local solar noon and was probably promoted by tidal stresses with the new moon which maximize near this hour. This is the strongest earthquake within about 300 km of this epicenter in the South Indian Ocean in at least 35 years. Comparable events occurred about 400 km northeast of today's epicenter with M 6.4 on November 29, 1999 and 24 year ago on November 15, 1999 with M 7.0.

The strongest earthquake felt in the world today was an M 5.9 in Papua New Guinea. NEIC reported it was felt with intensity III-IV in Papua at Finschhafen.

This is the strongest earthquake within about 200 km of this epicenter since an M 6.3 on April 19, 2023. Events of  M 6.7 and M 6.9 hit about 250 km northwest of today's epicenter on October 7, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 6.9 in Papua New Guinea.

It was followed by an M 6.7 and several moderate events of M>=5. An M 5.1 aftershock was felt in Madang and Port Moresby, Papua New Guinea. Other events in the series were not initially given intensities by NEIC however some felt data comes from Madang, PNG. No tsunami was reported as this epicenter is inland near the coast." (October 7, 2023)

 

Forecast 158010 had expected this event was likely within about 100 km of this epicenter around November 17.

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 7.1 in the area of the Banda Sea, November 8, 2023, where promoted seismicity is considered likely.

 

Today's projected seismicity map follows for the coming week.

 

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.

GLOBAL SEISMIC ENHANCEMENT WITH NEW MOON

 

EARTHQUAKE SUMMARY FOR NOVEMBER 13, 2023

 

Global seismicity today showed an increase in larger events including an M 6.0

southwest of the area of Sumatra, Indonesia; an M 5.7 in the Kermadec Islands, New Zealand and an M 6.1 in Papua New Guinea, Indonesia. The seismic forecast for the time around this new moon had read:

 

"The new moon arrived on November 13, 2023 at 09:27 UT.  Longitudes at local solar noon were near 37 East while those at local solar midnight are near 143 West longitude. These include Hawaii and areas of eastern Alaska and western Canada and to a lesser extent areas off the coast of Oregon and California while in the east they include Eastern Turkey where an M 7.7 hit on February 6, 2023 as well as Ethiopia and areas off southern Africa. These and surrounding areas are the most likely to see tidally enhanced seismicity at this time. A moderate to large aftershock is possible in Turkey at this time." (November 10-14, 2023)

 

The strongest earthquake in the world today was an M 6.1 in Papua New Guinea. NEIC reported it was felt with intensity IV in Rabaul, PNG. This occurred within about 1.5 hours of the new moon and may have been promoted by tidal stresses with that alignment (see above). It continues strong sequence of moderate earthquakes in the region which was addressed in the previous issue of this summary as:

 

"The strongest earthquake in the world today was an M 5.8 in Papua New Guinea. BMG reported iit was felt with intensity IX in Lerch, Jayapura, Papua; IV in Station Senggi, Keerom, Papua and III in Kaureh, Airu, in Keerom at Waris, Arso, Senggi, Web, Towe, Arso Barat, Yalfi, Kaisenar in Pengusingan Binting at Borne, Aboy, Batani, Murkim, Mofinop, Teiraplu, Nongme; in Yalukimo at Ubalihi, Talambo, Endomen, Kona and in Yalimo at Benawa. In the previous issue of this summary this activity was addressed as:

 

"The strongest earthquake in the world today was an M 5.9 in New Ireland.  This is the strongest earthquake in New Ireland since an M 6.0 on March 7, 2023.

At the time this summary noted:

 

 

"A series of moderately large to strong earthquakes occurred today with the full moon a possible trigger for this seismicity. A second promoter was the current geomagnetic storm. This can be seen as the larger events today occurred in three categories. Category 1 was the most active and followed the geomagnetic equator around the earth. Events of M 6.0 hit near the geomagnetic equator today in Mindanao, Philippines (M 6.0-6.2), New Britain (M 6.0) and the Solomon Islands (M 6.0) with lesser magnitude in the Molucca Sea (M 5.4), Andaman Islands (M 4.9), Central Peru (M 4.7) and Turkey (M 4.5, 4.7). Category 2 events occurred at high latitudes and included, among others,

 

... The last earthquake of M>=6 in the New Ireland region within about 250 km of today's epicenter was an M 6.3 on November 30, 2021." (November 11, 13, 2023, March 7, 2023)

 

Forecast 158010 had expected today's activity within about 25 km was likely around

November 15, 2023.

The earthquake in the South Indian Ocean of M 6.1 was not reported felt in this area. It occurred near local solar noon and was probably promoted by tidal stresses with the new moon which maximize near this hour. This is the strongest earthquake within about 300 km of this epicenter in the South Indian Ocean in at least 35 years. Comparable events occurred about 400 km northeast of today's epicenter with M 6.4 on November 29, 1999 and 24 year ago on November 15, 1999 with M 7.0.

An earthquake of M 5.7 also occurred today near the time of the new moon and local solar midnight in the Kermadec Islands. It was not reported felt in this remote region. This may be an aftershock of an M 6.1 northeast of this epicenter on October 23, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 6.1 in the Kermadec Islands. It was preceded by an M 5.1 foreshock and followed by an M 4.5 which followed near local solar noon while the M 6.1 occurred near local solar midnight. It is likely that this activity was promoted by tidal stresses which maximize near these times. The last earthquake in the Kermadec Islands of M>=6 occurred as an M 6.6 on September 8, 2023." (October 23, 2023)

 

Forecast 158234 had expected today's event in this region was likely around November 13.

An M 4.6 also occurred today in the border region of Turkey and Iran. NEIC reported this earthquake of M 4.6 in Azerbaijan was felt with intensity II-III in the area(s) of Azerbaijan in Sharur City. EMSC reported this earthquake of M 4.8 on the Turkey-Iran border  was felt with intensity II-III in the area(s) of on the Turkey-Iran border in Iran at Maku, Seyah Cheshmeh, and in Turkey at Dogubauazit, iand in Armenia at Yerevan, Prroshyan and K'anak'erravan.

This is at the maximum tidal stress longitude (see above) with today's new moon and was probably promoted by tidal stresses. Forecast 158124 had expected this activity was likely within about 200 km of this epicenter around November 17.

To the east of the event in Turkey, an M 5.3 occurred near the time of the new moon in Tajikistan. The last earthquake of equal or larger magnitude in  Tajikistan was an M 5.3 on October 2, 2023 but the last of larger magnitude was an M 5.8 on March 22, 2023. At the time this summary noted:

 

 

"... tidal triggering of seismicity had been expected in this and previous issues of this summary with this new moon ...

 

An M 5.9 also occurred in Tajikistan today. NEIC reported it was felt with intensity V in Choruh-Dairon, Tajikistan with maximum intensity VI in Sulukfu, Os, Kyrgyzstan with IV in Khujand, Matcha, Kofarnihon, Dushanbe, Navabadski, Tajikistan and III in Bekobod, Taskent, Uzbekistan. NEIC reported the aftershock of M 4.5 in Tajikistan was felt with intensity II-III in the area(s) of Uzbekistan at Tashkent and Salor. While this epicenter is about 400 km northwest of the  7.2 in Tajikistan of February 23, 2023, it is likely related to regional stress redistribution related to that mainshock. The M 5.8 occurred within about an hour of local solar midnight and was probably also promoted by strong tidal, geomagnetic and GRB effects which maximized near this hour." (March 23, 2023)

 

Forecast 158089 had expected today's event in Tajikistan was likely within about

100 km around November 15.

 

NEIC reported this earthquake of M 5.3 in Tajikistan was felt with intensity II-III in the area(s) of Tajikistan.

The strongest earthquake in the U.S. or Canada today was an M 4.4 in the eastern Andreanof Islands, Aleutians, Alaska. NEIC reported it was felt with intensity IV in Atka, Alaska. Recent earthquakes in the eastern Andreanof Islands of larger magnitude included an M 5.0 on November 3 and an M 6.4-6.7 on October 16, 2023. At the time of the November 3 event this summary noted:

 

 

"The strongest earthquake in the U.S. today was an M 5.0 in the Aleutians near Atka, Alaska where it was lightly felt. An M 6.5-6.7 hit about 200 km west of this on October 16, 2023 but this is the strongest earthquake within 200 km of this epicenters in the Andreanof Islands since an M 5.1 on January 26, 2023." (November 3, 2023)

 

Forecast 158169 had expected today's event was likely within about 25 km of

this epicenter around November 12, 2023.

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.

MODERATELY STRONG QUAKES CONTINUE IN NEW GUINEA

 

EARTHQUAKE SUMMARY FOR NOVEMBER 12, 2023

 

 

The strongest earthquake in the world today was an M 5.8 in Papua New Guinea. BMG reported it was felt with intensity IX in Lerch, Jayapura, Papua; IV in Station Senggi, Keerom, Papua and III in Kaureh, Airu, in Keerom at Waris, Arso, Senggi, Web, Towe, Arso Barat, Yalfi, Kaisenar in Pengusingan Binting at Borne, Aboy, Batani, Murkim, Mofinop, Teiraplu, Nongme; in Yalukimo at Ubalihi, Talambo, Endomen, Kona and in Yalimo at Benawa. In the previous issue of this summary this activity was addressed as:

 

"The strongest earthquake in the world today was an M 5.9 in New Ireland.  This is the strongest earthquake in New Ireland since an M 6.0 on March 7, 2023.

At the time this summary noted:

 

 

"A series of moderately large to strong earthquakes occurred today with the full moon a possible trigger for this seismicity. A second promoter was the current geomagnetic storm. This can be seen as the larger events today occurred in three categories. Category 1 was the most active and followed the geomagnetic equator around the earth. Events of M 6.0 hit near the geomagnetic equator today in Mindanao, Philippines (M 6.0-6.2), New Britain (M 6.0) and the Solomon Islands (M 6.0) with lesser magnitude in the Molucca Sea (M 5.4), Andaman Islands (M 4.9), Central Peru (M 4.7) and Turkey (M 4.5, 4.7). Category 2 events occurred at high latitudes and included, among others,

 

... The last earthquake of M>=6 in the New Ireland region within about 250 km of today's epicenter was an M 6.3 on November 30, 2021." (November 11, 2023, March 7, 2023)

 

Forecast 158010 had expected today’s activity within 25 km around November 15.

Other moderate activity in the Papua region of Indonesia also continued in  swarms north of New Guinea (including an M 5.3) and in Molucca (but at a reduced rate in this aftershock zone of the M 7.1 of November 8. Forecasts 158020 and 158014 had expected the activity in Papua was likely in mid-November within about 100 km of today's events.

The strongest earthquake in the U.S. or Canada today was an M 4.6 in the Fox Islands, Aleutians, Alaska. NEIC reported it was lightly felt in Akutan, Alaska.

This follows a similar M 4.5 near this epicenter of November 12, 2023. At the time (in the previous issue of this summary) it was noted as:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.5 in the Alaska Peninsula/Unimak Island, Alaska. NEIC reported it was lightly felt in the area of Sand Point, Alaska. An M 4.5 was also located in Alaska today in the Fox Islands, Aleutians. It was not reported felt in that remote area. The M 4.5 in the Fox Islands is the largest within about 150 km of that epicenter since an M 4.5  on July 30 while the event in the area south of Alaska last saw an M 4.5 or greater event  within about 150 km of today's epicenter on March 7, 2023 (M 4.5). Forecasts 158185 and 158167 had expected today's activity in these region was likely around November 12-13." (November 12, 2023)

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 7.1 in the area of the Banda Sea, November 8, 2023, where promoted seismicity is considered likely.

 

Today's projected seismicity map follows for the coming week.

 

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 IN SOUTHWEST PACIFIC

 

EARTHQUAKE SUMMARY FOR NOVEMBER 11, 2023

 

The southwest Pacific continued to see the world's strongest seismicity today.

Moderately large events occurred in New Ireland (PNG) with M 5.9; as aftershocks

in the Banda Sea (M 5.7) and in Vanuatu (M 5.5). These areas are near the geomagnetic equator and may have been promoted by the strong geomagnetic storm of the past several days as noted in previous issues of this summary:

 

"... this is the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term." (November 8-9, 2023)

 

The strongest earthquake in the world today was an M 5.9 in New Ireland.  This is the strongest earthquake in New Ireland since an M 6.0 on March 7, 2023.

At the time this summary noted:

 

 

"A series of moderately large to strong earthquakes occurred today with the full moon a possible trigger for this seismicity. A second promoter was the current geomagnetic storm. This can be seen as the larger events today occurred in three categories. Category 1 was the most active and followed the geomagnetic equator around the earth. Events of M 6.0 hit near the geomagnetic equator today in Mindanao, Philippines (M 6.0-6.2), New Britain (M 6.0) and the Solomon Islands (M 6.0) with lesser magnitude in the Molucca Sea (M 5.4), Andaman Islands (M 4.9), Central Peru (M 4.7) and Turkey (M 4.5, 4.7). Category 2 events occurred at high latitudes and included, among others,

 

... The last earthquake of M>=6 in the New Ireland region within about 250 km of today's epicenter was an M 6.3 on November 30, 2021." (March 7, 2023)

Aftershocks of the M 7.1 in the Banda Sea of November 8 also continued today with the maximum event of M 5.7 having been forecast in 158000 to occur in mid-November. This summary has covered this sequence extensively including in the previous issue as:

 

"The strongest earthquakes in the world today were an M 5.9 and M 6.2 aftershock in the Banda Sea region of Indonesia. BMG reported they were felt with intensity III in Maluku Tengah at Banda and II in Tanimbar at Wer Maktian, Tanimbar, Yaru, Wuar Labobar, Kormomolin, Niruamas, molu Maru; in Seran at Pulau Gorom, Wakate, Pulau Panjang, Teor, Gorom Timur and in Maluku at Damer. The M 6.2 was felt with intensity III in Maluku, Tanimbar and II in Seram, Ambon, Tual. This activity is aftershocks of the M 7.1 of November 8 in the Banda Sea." (November 11, 2023)

A moderately strong earthquake in the world also occurred today as an M 5.5 in Central Vanuatu. NEIC reported this earthquake was felt with intensity II-III in the area(s) of Central Vanuatu in Port-Vila and in Vila Shefa. A series of moderate to large earthquakes have occurred in Vanuatu since Tropical Cyclone hit the area in late October. This included an M 5.7 in southern Vanuatu on November 5; and M 5.6 in northern Vanuatu on October 28 and an M 6.0 in Southern Vanuatu on October 29. At the time of these events this summary noted the coincidence with the passage of TC Lola as:

 

 

"The strongest earthquakes in the world today were an M 6.0 and M 5.6 in Southern Vanuatu. NEIC reported it was felt with intensity VI in Vanuatu at Isangel and III in Vila Shefa with II-III in New Caledonia at We Iles, and Noumea. This was likely promoted by the passage of a strong Tropical Cyclone (Lola) through the area over the past several days as noted in previous issues of this summary:

 

"Tropical Cyclone Lola (01P) continued over central  Vanuatu today with winds up to 35 kts. This system is moving to the south and west. Some increases in seismicity in Vanuatu likely with this storm including a possible strong regional earthquake in the next three days." (October 25-28, 2023)

 

Today's M 6.0 in southern Vanuatu is the strongest since events of M 6.0-6.1 on September 28 and September 21, 2023." (October 28, 2023)

 

Forecasts 157950 had expected today's activity in Vanuatu was likely around November 7-9.

The strongest earthquake in the U.S. or Canada today was an M 4.5 in the Alaska Peninsula/Unimak Island, Alaska. NEIC reported it was lightly felt in the area of Sand Point, Alaska. An M 4.5 was also located in Alaska today in the Fox Islands, Aleutians. It was not reported felt in that remote area. The M 4.5 in the Fox Islands is the largest within about 150 km of that epicenter since an M 4.5  on July 30 while the event in the area south of Alaska last saw an M 4.5 or greater event  within about 150 km of today's epicenter on March 7, 2023 (M 4.5). Forecasts 158185 and 158167 had expected today's activity in these region was likely around November 12-13.

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.

IMMINENT ERUPTION IN ICELAND?

 

EARTHQUAKE SUMMARY FOR NOVEMBER 10, 2023

 

An imminent eruption is possible in the area near Reykjavik, Iceland.  Earthquakes today included an M 5.0 and 5.1 in the region of Grindavik, Iceland. This town of about 3500 has been ordered evacuated due to the likelihood of this eruption. EMSC reported these events were felt with strong intensity in Mosfellsbaer, Kopavogur, Keflavik, Suournesjabaer, Seltjarnarnes, Reykjavik, among others. This continues the current series of eruptions which began in 2021 - part of a sequence that occurs with about 700 year intervals and can last as long as 100 years. In this area of Iceland this involves motions between the North American tectonic and the European tectonic plates. Initial lava flows can be up to 100 feet per minute – faster than walking pace. There area some infrastructure near the site of this imminent eruption include the town of Grindavik several km away and a power plant and roads which could be damaged in an eruption. Several roads were actually reported damaged near Grindavik today by earthquakes.

 

Following is a listing of events in this Iceland swarm today of M>=4.0. A more  detailed listing of events of M>=3.5 can be found in the EUROPE section of this summary.

 Forecast 158195 had expected today's activity in Iceland was likely around November 12. The last earthquakes in Iceland with M>5.2 occurred in March and April 2021 and on October 20, 2020 (M 5.0). At the time this summary noted:

 

 

"An M 5.6 earthquake in Iceland today was accompanied by a series of lighter shocks. The mainshock was reported felt in southwestern Iceland with intensity V in Keflavik and IV in Harnarfjordur, Gardabaei, Alflanes, Kopavogur, Seltjarnarnes, Reykajik, Grundarhverfi and III in Mosfellsbaer, and Vogar.

This earthquake occurred within minutes of local solar noon and was likely promoted by high tidal stresses of the new moon which maximize near this time. This is the strongest earthquake in southern Iceland within about 200 km of this epicenter since an M 6.3 more than 12 years ago on May 29, 2008. Other such events occurred in 1998 and 2000. It is likely that this was triggered by energy from the Alaska Peninsula quake of M 7.5 yesterday combined with high tidal stresses and by the geomagnetic storm of the past day."

An unusually large M 5.0 also shook the area of the Dominican Republic today. NEIC reported it was felt with maximum intensity up to VI in Las Matas de Santa Cruz. The mainshock was preceded by an M 3.6 in the Mona Passage. EMSC reported strong intensity in the Dominican Republic at San Fernando de Monte Cristi, Cana Chapeton, Mao, Moncion, Amima, Imbert, Pignon, Haiti, Santiago de los Caballeros, Puerto Plata, Santiago among others. Earthquakes of M 5.0 hit in the Dominican Republic on February 1, 2023 and June 14, 2021 but the last event in the area within about 200 km of today's epicenter occurred on September 23, 2018 with M 5.2 and an M 5.1 on January 23, 2012. At the time of the M 5.2 in September 23, 2018 this summary noted:

 

 

"An earthquake of M 5.2 also shook the Dominican Republic near local solar midnight today. NEIC reported it was felt with intensity V in Montellano, Jarabacoa, La Vega and IV in the Dominican Republic in Sabana Grande de Boya, Las Terrenas, Villa Vazquez, Sabaneta, Moncion, San Jose de las Matas, Villa Gonzalez, Palmar Arriva, Santiago, Sosua, Moca, Jamao al Norte, Mayaguez, Puerto Rico, Santo Domingo, El Carril, Nagua, Cotui, Bonao, San Francisco e Macoris, Tireo, Gaspar Hernandez, Saint-Raphael, Baitoa, Puerto Plata, Altimira, Luperon, Mao, and Villa Elisa. It was probably promoted by tidal stresses associated with the full moon which maximized near this hour. The last earthquake in the Dominican Republic within about 150 km of today's epicenter with M>=5.2 was an M 5.5 on January 5, 2012 and is the second strongest regional aftershock to date since January, 2010 when an M 7.0 killed hundreds of thousands in the area." (September 23, 2018)

 

The mainshock of M 5.0 occurred within minutes of local solar noon and may have been promoted by tidal stresses which maximize near this hour.

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 world today was an M 6.0 in the Banda Sea, Indonesia. BMG reported it was felt with intensity III in Maluku at Banda, Tanimbar in Molu Maru, Tanimbar, Wer Tamrian, Maktian, Yaru, Wuar Labobar, Kormomolin, Nirumas; and II in Seram Bagian at Wakate, Pulau, Teor. This activity is aftershocks of the M 7.1 in the Banda Sea of November 8 as noted in this summary in the previous issue of this summary:

 

 

"The strongest earthquake in the world today was an M 6.7 in the Banda Sea of Indonesia. This event was also felt in northern Australia at Darwin. BMG reported the mainshock of M 7.1 was felt with intensity up to V in the Tanimbar Islands. BMG reported this activity in the Tanimbar region was felt with intensity IV in Bandaneira, III in Maluku Tengah, Banda, Maluku Tenggara, at Kecil, Manyeuw, Hoat Sorbay, in Tanimbar at Tanimbar Selatan, Selaru, Wer Tamrian, Wer Maktian; in Seram Bagian in Maluku Barat Daya and in Kota Tual and many other communities experienced lesser shaking. No tsunami was observed or expected with this event." (November 9, 2023)

 

Today's M 6.0 occurred within minutes of local solar noon and was probably

promoted by strong tidal stresses which predominate at this hour. Forecast 158000 had expected today's activity was likely around November 12.

An earthquake in Eastern New Guinea also occurred today in Eastern New Guinea, PNG. NEIC reported these earthquakes of M 5.4 and M 5.0 in New Guinea were felt with intensity up to V in the area(s) of New Guinea in Madang.  EMSC reported moderate shaking in Madang, Papua New Guinea. This is probably an aftershock of an M 6.7 on October 7, 2023. At that time this was described in this summary as:

 

 

"The strongest earthquake in the world today was an M 6.9 in Papua New Guinea.

It was followed by an M 6.7 and several moderate events of M>=5. An M 5.1 aftershock was felt in Madang and Port Moresby, Papua New Guinea. Other events in the series were not initially given intensities by NEIC however some felt data comes from Madang, PNG. No tsunami was reported as this epicenter is inland near the coast." (October 7, 2023)

 

Forecast 158011 had expected today's event was likely within about 50 km around November 13.

Otherwise it was a quiet day in global seismicity. Earthquakes of M 5.1 and M 5.2 occurred in central Vanuatu and in Peru. These may have been promoted by strong tidal stresses as the event in Peru occurred within minutes of local solar noon and the M 5.1 in Vanuatu occurred near local sols midnight, both times when tidal stresses maximize. Forecast 157950 had expected enhanced seismicity in central Vanuatu within about 50 km of today's event was likely in early November while the event in Northern Peru of M 5.1 had been anticipated in forecast 158012 to occur within 100 km of this epicenter around November 11.

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 5.2 in the Mentone  area of Texas. It was reported with intensity up to VI in Mentone, Texas and with moderate shaking in Carlsbad, New Mexico an in Fabens, El Paso, Texas among others.

 

This event was probably promoted by well injection of waters following fracking and extraction of oil and gas in the region. This may also have been promoted by geomagnetic effects associated with the current geomagnetic storm and/or by tidal stresses associated with the upcoming new moon as described in this issue in previous summaries as:

 

 

"The new moon will arrive on November 13, 2023 at 09:27 UT.  Longitudes at local solar noon are near 37 East while those at local solar midnight are near 143 West longitude. These include Hawaii and areas of eastern Alaska and western Canada and to a lesser extent areas off the coast of Oregon and California while in the east they include Eastern Turkey where an M 7.7 hit on February 6, 2023 as well as Ethiopia and areas off southern Africa. These and surrounding areas are the most likely to see tidally enhanced seismicity at this time. A moderate to large aftershock is possible in Turkey at this time." (November 7-8, 2023)

 

A series of minor aftershocks followed the M 5.2 in western Texas today and continued throughout the day. The M 5.2 is the strongest earthquake in Texas since an M 5.4on December 16, 2022 about 200 km northeast of this epicenter and an M 5.4 on November 16, 2022 which began the sequence of events in this region of the Permian Basin of Texas. At the time this summary noted:

 

 

 

"The strongest earthquake in the U.S. or Canada today was an 5.3-5.4 in western Texas. NEIC reported it was felt with maximum intensity V in Texas at Barstow, and in Jal, New Mexico with intensity IV in Texas at Wink, Pecos, Salt Flat and III in Mentone, Loving, Pyote, Van horn among others. It was followed by an aftershock of M 4.1 in Western Texas. NEIC reported it was felt with maximum intensity V in Pecos, Texas and IV in Odessa, Texas. Lesser intensity of II-III was reported felt in New Mexico at Carlsbad, Eunice, Artesia, Hobbs and in Texas at Fort Davis, Coyanosa, Odessa, Fort Stockton, among others and may have been felt as far as Oklahoma. An M 3.8 aftershock was also felt in western Texas and New Mexico today. NEIC reported maximum intensity IV in El Paso, Texas with III in Canutillo, Texas and in New Mexico at Carlsbad and Lovington. The M 3.8 was preceded by a swarm of events of M 2.9, 3.5, 2.8... felt in the same area of Texas and New Mexico. The last earthquake within about 250 km of today's epicenter with magnitude greater than or equal to M 5.3 in Texas was an M 5.7 about 200 km to the southeast of today's epicenter (on April 14, 1995) . That was the only such regional earthquake in western Texas in at least 35 years." (November 17, 2022)

 

Forecast 157830 had expected today's event within about 50 km of this epicenter was likely around November 8. The mainshock parameters are listed below. A listing of events of M>=2 today can be found under the "ROCKY MOUNTAINS" section of this summary.

Several moderate earthquakes and a number of minor ones occurred today in the current series in Iceland. The largest of today's events were of M 4.5 and 4.6.

They were reported by EMSC to have been felt with moderate intensity in Iceland in the Reykjavik area at Grindavik, Reykjanesbaer, Reykjavik, Seltjarnarnes,   These events were probably promoted by strong geomagnetic stresses associated with the current geomagnetic storm at high latitudes as noted in previous issues of this report:

 

"The geomagnetic field saw major storm conditions today. The AP level was 40.  High latitudes  saw major storm conditions with AP 51. Middle latitudes were at minor storm conditions with AP 27. This is the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term.." (November 6-7, 2023)

 

Five events of M>=4.1 were reported today in this area. Most of this activity occurred within an hour of local solar midnight and may have been promoted by tidal stresses which maximize near this hour. There is a possibility that this will lead to larger events and/or a continuation of the eruption that began in 2021 after about 700 years of non-eruptive activity. Forecast 157925 had expected today's activity within about 100 km was likely around November 7.

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 AND MAJOR QUAKES HIT BANDA SEA WITH GEOMAGNETIC STORM

 

EARTHQUAKE SUMMARY FOR NOVEMBER  7, 2023

 

 

The strongest earthquakes in the world today were a pair of strong to major earthquakes of M 6.7 and 7.1 in the Banda Sea, Indonesia. NEIC reported it was felt with maximum intensity III in the Banda Sea, Indonesia area. The mainshock of M 7.1 was preceded about a minute early by a foreshock of M 6.7 which was felt in the area with maximum intensity VI. These events were also felt in northern Australia at Darwin. BMG reported the mainshock of M 7.1 was felt with intensity up to V in the Tanimbar Islands. BMG reported this activity in the Tanimbar region was felt with intensity IV in Bandaneira, III in Maluku Tengah, Banda, Maluku Tenggara, at Kecil, Manyeuw, Hoat Sorbay, in Tanimbar at Tanimbar Selatan, Selaru, Wer Tamrian, Wer Maktian; in Seram Bagian in Maluku Barat Daya and in Kota Tual and many other communities experienced lesser shaking. No tsunamis were observed or expected with these events. A moderate foreshock hit the region yesterday and was reported in this summary as:

 

 

"The strongest earthquake near the geomagnetic equator in Indonesia today was an M 5.2 in the Banda Sea.  EMSC reported this earthquake of M 5.2 in Banda Sea, Indonesia was felt with intensity II-III in the area(s) of Banda Sea, Indonesia in Dili, Timor. BMG reported intensity III-IV in Timur, Alor, Nusa, Tengara, Maluku, Tengah Selatan, among others. This follows a relatively quiet period in Indonesia over the past week and probably is the first salvo of enhanced seismicity in the area with the major geomagnetic storm of yesterday and today (see above). The last earthquake of M>=5.2 in the Banda Sea area was an M 5.8 on September 23, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 5.8 in the Banda Sea, Indonesia at a deep focus. NEIC reported it was felt in East Timor at Dili in Dili and Dare and in northern Territory, Australia with IV in Howard Springs, Katherine and II-III in Coonawarra, Darwin, Humpty Doo-MacMinns Lagoon. This is the largest earthquake within about 200 km of this epicenter since an M  5.9 on August 29, 2023, and an M 6.2 on May 24, 2023. A major M 7.6 hit near today's epicenter on January 9, 2023. This may be an aftershock of that mainshock." (November 7, 2023, September 23, 2023)

 

The strongest earthquake within about 250 km of today's earthquake in Indonesia with M>=7.1 occurred on January 9, 2023 with M 7.6. At the time this summary noted:

 

“When a similar M 7.5-7.6 hit at deep focus near today's Indonesian epicenter

on January 27, 2006 this summary noted in this regard:

 

"A major earthquake initially given magnitude of M 7.7 occurred today in the Banda Sea region of Southern Indonesia south of Ambon, Moluccas. Data on the NEIC website indicates that this event was felt with maximum intensity V at Dili, East Timore and with intensity III in northwestern Australia at Darwin, Howard Springs and Humpty Doo-MacMinns Lagoon and with lesser intensity at Jabiru and Palmerston, Australia nearly 900 km to the southeast of this epicenter. Press accounts on Associated Press indicate that the earthquake was felt strongly on Ambon, the capital of Maluku province. Residents of Ambon ran out of homes to higher places in fear of  a tsunami. The quake was also felt with lesser intensity at Bali, Sorong and in south Sulawesi province, Indonesia. Residents also fled their homes about 440 km to the south in East Timor. There were no immediate reports of serious damage or casualties. The earthquake hit at a depth of about 350 km and there is no danger of a major tsunami from earthquakes which occur at such depths and do not propagate to the surface. Some local landslide tsunamis may occur, but in this case the shaking on the surface was probably not sufficient to trigger these. Strong earthquakes of M 7.5-8.5 have hit the area in 1963, 1950, 1948, 1938, 1917-1918 and 1899. Like most of the other large events in the past month, this epicenter is located at the Core-mantle Shadow Zone Boundary (MSZB) from the strong M 7.4 which hit the South

Atlantic on Jan. 2, 2006." (January 9, 2023)

 

Other major earthquake in the past 10 years occurred at intermediate focal depths of 100-400 km with M 7.3 on December 29, 2021 and June 24, 2019. Today's event is the strongest shallow focus earthquake in the area of M>=7.1 in at least 30 years (an M 7.3 at 77 km depth occurred near today's epicenter on December 20, 1992.  Most large earthquakes in this region in the past 35 years have occurred in the months of November through January (7 of 9 of M>=7.1). This suggests some seasonal trigger is likely - perhaps related to El Nino events and water loading.

 

Today's mainshocks occurred near local solar noon and may have been promoted by tidal and/or geomagnetic stresses with the current geomagnetic storm which maximize near this hour. The M 7.1 is the strongest earthquake in the world since a similar M 7.1 on August 28, 2023 in the area of Java and Bali. Events of slightly larger magnitude in the past half year occurred with M 7.2 in the Fox Islands on July 16, 2023 and in the Tonga region with M 7.2 on June 15, 2023.

 

Forecast 157725 had expected today's Banda Sea activity was likely within about 10-100 km of these epicenter most likely around November 6.

An unusual earthquake of M 4.5 hit northern Norway today. EMSC reported it was felt with light to moderate intensity in Norway at Meloy, Glomfjord,eipa, Mo i Rana, Nesna, Bodo, Vefsn. This is the strongest earthquake in Northern Norway within about 250 km of this epicenter since an M 4.7 on December 20, 1997. No earthquakes of larger magnitude have occurred in this area in the past 30 years. A series of events in January, 1992 about 100 km northeast of today's epicenter in Northern Norway occurred with M 4.6, 4.6 and 4.8.

 

Today's earthquake occurred near local solar midnight and may have been promoted by tidal stresses. This earthquake epicenter is located at 103 degrees from the M 7.1 in the Banda Sea and may have been promoted by energy from that source. A similarly located event today occurred as an M 4.1 in the Istanbul region of Turkey.

An M 5.3 in Southern Xinjiang, China was followed by a series of moderate  aftershocks.  NEIC reported this earthquake of M 5.3 in Xinjiang, China was felt with intensity II-III in the area(s) of Xinjiang, China in Tumxuk.  EMSC reported the mainshock was felt with moderate intensity in Kyrgyzstan at Cholpon-Ata and in Kazakhstan at Almaty, Pervomayka. EMSC an aftershock of M 4.8 was felt with moderate intensity in Issyk Kul, Kyrgyzstan and Almata, Kazakhstan. The mainshock occurred within minutes of local solar midnight and may have been promoted by tidal and geomagnetic effects associated with the current geomagnetic storm. Today's M 5.3 is the strongest recorded in southern  Xinjiang, China within about 200 km of today's epicenter since an M 5.3 on  July 2, 2022 and a similar M 5.3 on May 9, 2020 but the last event in the area of significantly larger magnitude in the past 10 years was an M 6.0 on January 19, 2020.

 

Forecast 157867 had expected today's events in this region were likely within about 100 km around November 8, 2023.

Other moderately strong earthquake, perhaps related to the current geomagnetic storm occurred with M 5.4, 5.5 and 4.7 in the Solomon Islands and as an M 5.0 in the Northern Mariana Islands, both about 10 degrees from the geomagnetic equator as anticipated at this time following the major geomagnetic storms of November 4-7. These were probably felt in the Guadalcanal region. Forecast 157949 had expected this Solomon Island regional activity in early November.

The strongest earthquake in the U.S. or Canada today was an M 4.4 in the Rat Islands, Aleutians. This event was not reported felt in this remote area. An M 5.1 hit the Rat Islands about 200 km east of today's epicenter on November 5, 2023 but the last event within 200 km of equal or greater magnitude was an M 5.7 about 150 km east of this epicenter on June 8, 2023. At the time this summary noted in this regard:

 

 

"The strongest earthquake in the world today was an M 5.7 in the Rat Islands, Aleutians, Alaska. NEIC reported a report of VII intensity in the area generally light intensity II-III in this remote epicentral area.

The mainshock was followed by aftershocks of M 4.6, 4.2 and 4.6 which were not felt. This is the strongest earthquake in the Rat Islands since an M 6.3 on December 14, 2022 and an M 6.3 a year ago on June 4, 2022." (June 8, 2023)

 

Today's event occurred within minutes of local solar midnight and may have been promoted by strong tidal stresses and/or geomagnetic storm which effects maximize near this hour.

 

Forecast 157913 had expected today's event in the Rat Islands within about

50 km of the epicenter was likely around November 5.

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.

GEOMAGNETIC STORM CONTINUES; BEGINS TO ENHANCE EQUATORIAL SEISMICITY

 

EARTHQUAKE SUMMARY FOR NOVEMBER  6, 2023

 

The strongest earthquake in the world today was an M 5.5 in the Central Mid-Atlantic Ridge. It was not felt in this remote area. This event occurred near local solar noon - a time when geomagnetic and tidal stresses maximize.  It coincided with a major geomagnetic storm as reported in this and the previous issue of this summary as:

 

"The geomagnetic field saw major storm conditions today. The AP level was 40.  High latitudes  saw major storm conditions with AP 51. Middle latitudes were at minor storm conditions with AP 27. This is the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term.." (November 6-7, 2023)

 

This event, near the geomagnetic equator is likely to have been promoted by the current geomagnetic storm. A series of moderate earthquakes also occurred near the geomagnetic equator today in Indonesia an area which is likely to experience enhanced seismicity in the next several days with this storm.

 

Today's event is the strongest within about 200 km in this area of the Mid-Atlantic as an M 6.2 on October 9, 2022. The only other such event in the area in the past five years was an M 5.7 on September 1, 2021.

 

Forecast 157727 had expected today's event in the Central Mid-Atlantic was likely around November 10.

The strongest earthquake near the geomagnetic equator in Indonesia today was an M 5.2 in the Banda Sea.  EMSC reported this earthquake of M 5.2 in Banda Sea, Indonesia was felt with intensity II-III in the area(s) of Banda Sea, Indonesia in Dili, Timor. BMG reported intensity III-IV in Timur, Alor, Nusa, Tengara, Maluku, Tengah Selatan, among others. This follows a relatively quiet period in Indonesia over the past week and probably is the first salvo of enhanced seismicity in the area with the major geomagnetic storm of yesterday and today (see above). The last earthquake of M>=5.2 in the Banda Sea area was an M 5.8 on September 23, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 5.8 in the Banda Sea, Indonesia at a deep focus. NEIC reported it was felt in East Timor at Dili in Dili and Dare and in northern Territory, Australia with IV in Howard Springs, Katherine and II-III in Coonawarra, Darwin, Humpty Doo-MacMinns Lagoon. This is the largest earthquake within about 200 km of this epicenter since an M  5.9 on August 29, 2023, and an M 6.2 on May 24, 2023. A major M 7.6 hit near today's epicenter on January 9, 2023. This may be an aftershock of that mainshock." (September 23, 2023)

 

Forecast 157725 had expected today's event in Banda about 150 km northeast of today's epicenter was likely around November 6.

A moderate aftershock occurred today with M 5.3 in the area of Nepal. This earthquake follows an M 5.6 in Nepal of November 3, 2023, the largest aftershock to date in the area. Forecast 157547 had expected enhanced seismicity in this region in late October or early November, 2023. 

 

NEIC reported this earthquake of M 5.3 in Nepal was felt with intensity up to IV in the area(s) of Nepal in Dailekh. EMSC reported moderate shaking in Nepal at Dailekh, Birendranagar, Baliya, Nanpara, Butwal, Pokhara, Bharatpur, Kirtipur, Manmaiju, Kathmandu,  and in India at Patna, Bihar, Noida, Haldwani, Gorakhpur,  Gonda, Lucknow.

The strongest earthquake in the U.S. or Canada today was an M 4.1 in the Kodiak Island area of Alaska. NEIC reported this earthquake of M 4.1 in the Alaska Peninsula was felt with intensity II-III in the area(s) of the Alaska Peninsula in Larson Bay. The last earthquake of M>=4 in the Kodiak Island area was an M 4.5 on January 25, 2023. Several light foreshocks of today's events hit the area on October 21 and 22, 2023 with M 3.1 and 3.0. Forecast 157921 had expected today's earthquake in the area was likely around November 4, 2023.

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 GEOMAGNETIC STORM MAY ENHANCE GLOBAL SEISMICITY

 

EARTHQUAKE SUMMARY FOR NOVEMBER  5, 2023

 

A strong geomagnetic storm hit the earth today. This storm is the strongest recorded since April 24, 2023. It is likely to dampen global seismicity over the next two days and then to increase the size of events after that as reported in this summary:

 

"The geomagnetic field saw major storm conditions today. The AP level was 57.  High latitudes  saw major storm conditions with AP 58. Middle latitudes were at minor storm conditions with AP 30. This is the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term." (November 6, 2023)

 

The strongest earthquake in the U.S. or Canada today was an M 5.1 in the Rat Islands, Aleutians, Alaska. It was not reported felt in this remote area. This event occurred near local solar midnight and was probably promoted by the strong geomagnetic storm today (see above) which maximized at high latitudes near this hour. This is the strongest earthquake in the Rat Islands since an M 5.7 on June 8, 2023. At the time this summary noted in this regard:

 

"The strongest earthquake in the world today was an M 5.7 in the Rat Islands, Aleutians, Alaska. NEIC reported a report of VII intensity in the area generally light intensity II-III in this remote epicentral area. The mainshock was followed by aftershocks of M 4.6, 4.2 and 4.6 which were not felt. This is the strongest earthquake in the Rat Islands since an M 6.3 on December 14, 2022 and an M 6.3 a year ago on June 4, 2022. At that time this summary noted in this regard: 

 

"The event of M 6.3 in the Rat Islands was not reported felt in this remote area. This is the strongest earthquake in the Rat Islands since an M 6.4 on April 2, 2019. These appear to be aftershocks of the M 7.9 that hit about 50 km southeast of today's epicenter on June 23, 2014. Today's event occurred near local solar noon and was likely promoted by high tidal stresses which maximize near this hour. It may also have been promoted by the recent geomagnetic storm." (June 8, 2023, June 5, 2022)

 

Forecast 157913 had expected today's M 5.1 was likely within about 50 km around

November 8.

The strongest earthquake in the world today occurred in southern Vanuatu with M 5.7. It continues elevated seismicity in this area associated with the passage of major Tropical Cyclone Lola at the end of October as reported in this summary on October 28:

 

"The strongest earthquakes in the world today were an M 6.0 and M 5.6 in Southern Vanuatu. NEIC reported it was felt with intensity VI in Vanuatu at Isangel and III in Vila Shefa with II-III in New Caledonia at We Iles, and Noumea. This was likely promoted by the passage of a strong Tropical Cyclone (Lola) through the area over the past several days as noted in previous issues of this summary:

 

"Tropical Cyclone Lola (01P) continued over central  Vanuatu today with winds up to 35 kts. This system is moving to the south and west. Some increases in seismicity in Vanuatu likely with this storm including a possible strong regional earthquake in the next three days." (October 25-28, 2023)

 

Today's M 6.0 in southern Vanuatu is the strongest since events of M 6.0-6.1 on September and September 21, 2023. At the time this summary noted in this regard:

 

 

The strongest earthquake of the day in the world was an M 6.1 in northern Vanuatu. NEIC reported it was felt with intensity IV in Luganville, Sanma, Vanuatu. This may be an aftershock of an M 6.5 which occurred on August 16, 2023. At the time this summary noted in this regard:

 

"The strongest earthquake in the world today was an M 6.5 in northern Vanuatu. The mainshock was reported by NEIC to have been felt with intensity VII in Vanuatu at Sola Torba and IV in Sanma at Port Olry and Luganville and possibly in the Solomon Islands and New South Wales, Australia. The mainshock was preceded by an M 5.2 regional foreshock several hours earlier. That event was

felt with intensity III in Luganville, Sanma, Vanuatu. An aftershock of M 4.3 was felt with intensity IV in Port Olry, Sanma, Vanuatu. The mainshock within minutes of local solar midnight and most likely was promoted by tidal stresses with the new moon which was completed within hours of the occurrence of this earthquake.

 

...

 

Today's event of M 6.5 is the largest in northern Vanuatu since an M 7.0 about 150 km south of this epicenter on January 8, 2023. The last within 100 km at this magnitude level was an M 6.6 on January 15, 2019. (October 28, 2023, September 21, 2023, August 16, 2022)

 

Forecast 157968 had expected today's event within about 50 km was likely  around November 2.

Unusual earthquakes of M 3.6 in Portugal and M 4.3 in Albania occurred in Europe today. At higher latitudes these may be related to immediate effects of today's geomagnetic storm. The last earthquake in Portugal within about 200 km of today's epicenter with M>=3.6 was an M 3.8 on September 15, 2023. No earthquakes of larger magnitude than this have been recorded in this area in the past three years.

 

EMSC reported this earthquake of M 3.8 in Portugal was felt with intensity II-III in the area(s) of Portugal in Silves, Monchique, Portimao, 

 

The earthquake in Portugal had been expected within about 150 km between November 3 and 7 in forecast 157814.

The last earthquake of equal or larger magnitude than M 4.3 in Albania was an M 4.4 and 4.8 on March 23, 2023 about 100 km southeast of today's epicenter. That earthquake was also closely associated with a strong geomagnetic storm. At the time this summary noted:

 

"An unusually large earthquake of M 4.8-4.9 also occurred shortly after the GRB in Albania. This is the largest earthquake in Albania since an M 5.5 on January 9, 2022." (March 23, 2023)

 

 

NEIC reported today's earthquake of M 4.3 in Albania was felt with intensity II-III in the area(s) of Albania in Cerrik.  EMSC reported it was lightly felt in Albania at Paper, Cerrik, Elbasan, Berzhite, Sinaballaj, Tirana, Farka e Madhe, Paskuqan, Kutalli, Kruje and Durres among others.

 

The earthquake in Albania had been expected within about 50 km around November 5  in forecast 157889.

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.

MODERATELY STRONG EARTHQUAKE DEADLY IN NEPAL

 

EARTHQUAKE SUMMARY FOR NOVEMBER  3, 2023

 

 

An earthquake of M 5.6-6.4 hit the region of Nepal today. Initial reports indicated that at least 157 were killed and 170 injured in the Jajarkot area of western Nepal. Many buildings and houses collapsed during the earthquake which was felt as far as New Delhi, India.  It is expected that many more were killed in the quake but are yet unaccounted for in the Kathmandu region of Nepal. In some villages more than 90% of the houses were destroyed. The Indian Center for Seismicity reported it with M 6.4 at 18:02:54 UT (CENC reported M 5.9 at 18:02:54 UT) was felt with intensity up to VIII and in India at Pithoragarh, Uttarakhand and Uttar Pradesh. NEIC reported this earthquake of M 5.6 in Nepal was felt with intensity II-III in the area(s) of Nepal in Jumla (VI) and Pokhara, Kaski.  EMSC reported VIII in Nepal at Musikot, Birendranagar, VII in Dhangadhi, Tansen, IV-VI in Pokhara, Karahiya, Sunwal, Basti, India among others. NEIC reported it was felt with maximum intensity VIII (with damage) in Amargadhi, Nepal and with II in Nepal and Dhangadhi, Nepalganj, Banke, Dailekh and in Uttaranchal, India at Pithoragarh, Bageshwar, Bhowali, Haldwai cum Kathgodam, Nainital. This earthquake occurred within minutes of local solar midnight and may have been promoted by tidal stresses which maximize near this hour. When an M 5.3 foreshock occurred in Nepal on October 22, 2023 this summary noted (on November 1, 2023):

 

 

"A series of moderate earthquakes also occurred today in the area from Nepal to

Iran. This area saw the maximum lunar eclipse of October 28 as reported in previous issues of this summary:

 

"The full moon arrived on October 28, 2023 at 20:24 UT. Longitudes which were near local solar midnight at this time are near 50 East while those at local solar noon are near 130 West. In the east these include areas of Iran and the horn of Africa and in the east much of western North America including the area from California north to British Columbia and southeastern Alaska. These are the areas most likely to see tidally enhanced seismicity within a week of this full moon. This full moon is nearer the earth with high tidal stresses and will be accompanied by a lunar eclipse. This is a partial eclipse which will be fullest in the area of Yemen and Ethiopia at local midnight. It will also be visible in eastern U.S. at moonrise and throughout most of Africa, Asia and Europe maximizing in western Afghanistan, Iran, and the Gulf of Aden and Ethiopia. The eclipse will maximize at 20:15 UT. The last Saros series lunar eclipse occurred on October 17, 2005. It occurred within days of the M 7.5 in Pakistan and India of October 8, 2005 which killed more than 100,000 people. Earthquakes nearer the eclipse time included strong events in the Marshall Islands, Sumatra, Southern California, Western Turkey, Taiwan (M 7.0), Tokyo, Japan (M 6.6) and Fiji.  A strong earthquake is likely to accompany or to follow several days after the eclipse in this region. This is the 11th lunar eclipse in the Pharos series which began in 1843." (October 24-30, 2023)

 

The activity in India near Nepal continued elevated activity in that region of the past several days which included an M 5.3 on October 22, 2023 and an M 5.7 on October 3, 2023. This was reported at the time as:

 

 

"A moderately strong earthquake of M 5.7 hit the region of Nepal today. NEIC reported it was felt with maximum intensity VIII (with damage) in Amargadhi, Nepal and wiht II in Nepal and Dhangadhi, Nepalganj, Banke, Dailekh and in Uttaranchal, India at Pithoragarh, Bageshwar, Bhowali, Haldwai cum Kathgodam, Nainital. A foreshock of M 4.9 about 30 minutes before the mainshock was felt with intensity V in Nepal at Dhangadhi, Birendranagar, and in Uttaranchal, India at Nainital, and in Uttar, Pradesh, in Bareli, Lakhimpur, Rudraprayag, Moradabad, and Auras. NEIC reported an aftershock of M 4.8 in  Uttaranchal, India was felt with intensity II-III in the area(s) of  Uttaranchal, India in Kotdwara. A similar M 5.7 hit this region of Nepal on January 24, 2023 and today's activity may be considered aftershocks of that but a stronger M 6.3-6.6 hit the region on November 8, 2022. At the time of the event in January, 2023 this summary noted:

 

"The strongest earthquake felt in the world today was an M 5.6-5.7 in Nepal. NEIC reported it was felt with maximum intensity V in Dipayal, Doti, Nepal with IV in Kichha, Uttaranchal, India. Intensity II-III was also felt in Nepal in Tansen, Palpa, and Pokhara, Kashi. In India this earthquake was felt with intensity II-III in Uttaranchal at Almora, Clement Town, and in Uttar Pradesh at Lakhnau, Cawnpore, Dankaur and Ghaziabad among other communities. EMSC reported light to moderate shaking in Nepal at Simikot, Birendranagar, Dhangadhi, Kohalpur, Kanchanpur, Pokhara, and in India at Pithoragarh, Almora, Haldwani, Pilibhit, Bhikia Sain, Shahjahanpur among other communities. This is the strongest earthquake in Nepal within about 200 km of this epicenter since an M 6.0 on September 25, 2008 and an M 6.2 on April 7, 2005 and July 11, 2004, the only such events in Nepal in the past 35 years.  " (October 3, 2023, January 24, 2023)

 

An M 5.6 hit Nepal a year ago on November 8, 2022 about the same time of day as today's event of M 4.1. It is likely further moderate to large earthquakes will occur in Nepal in the coming week." (November 1, 2023)

 

Forecast 157590 had expected today's event within about 250 km was likely around October 28.

The strongest earthquake in the U.S. or Canada today was an M 4.6 in the Near Islands, Aleutians, Alaska. It was not reported felt in this remote area. The last earthquake of equal or larger magnitude in the Near Islands was an M 4.8 on May 20, 2023, the only such previous event in the area during 2023. Forecast 157913 had expected today's earthquake within about 150 km was likely arond November 5.

An M 4.0 also occurred west of Los Angeles, California today.  EMSC reported this earthquake of M 4.0 in Southern California was felt with intensity II-III in the area(s) of Southern California in Ojai, Santa Paula, Saticoy, Ventura, Camarillo, Oxnard, Channel Islands Beach, Carpinteria, Simi Valley, Santa Susana, Santa Barbara, Goleta, La Canada Flintridge among others. This earthquake occurred within minutes of local solar noon and was probably promoted by tidal stresses which maximize near this hour. It is the largest earthquake within about 100 km of this epicenter since an M 5.1 on August 20, 2023.

At the time this summary noted:

 

 

"This series began near local solar noon and may have been promoted by tidal stresses which maximize near this hour. An M 3.4 shook this area to the north on August 17, 2023 with the new moon within minutes of local solar noon and was probably promoted by tidal stresses from the new moon of August 16" (August 20, 2023)

 

Forecast 157839 had expected this event was likely about 50 km to the northeast of today's epicenter in early November, 2023.

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 world today was an M 5.2 in Northern Greece.

NEIC reported this earthquake of M 5.1 in Northern Greece was felt with intensity III-IV in the area(s) of Northern Greece in Prokopi.  EMSC reported this earthquake of M 5.1 in Northern Greece was felt with intensity III-IV in the area(s) of Northern Greece in Limni, Nea Artaki, Chalkida, Malakonta, Plaka Dilesi, Istiaia among others. The last earthquake of M>=5.2 within about 200 km of this epicenter in Greece was an M 5.2 on October 8, 2022. At the time this summary noted:

 

 

"An M 5.2 earthquake was widely felt in Greece today. It was felt with intensity IV in Greece in Esfina, Calaxidion, Delfoi, Arakhova, Diakopton, Lekhaion, Isthmis Korinthia, Kineta (V), with III in Kirra, Fokis and Korinthos according to data from NEIC. This is the strongest earthquake in Greece within about 150 km of this epicenter since an M 5.5 on February 17, 2021 and an M 5.2 on January 12, 2021. The last earthquake in this area of M>5.5 was an 6.4 on June 8, 2008." (October 8, 2022)

Today's projected seismicity map follows for the coming week.

 

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 ATACAMA, CHILE AND FIJI

 

EARTHQUAKE SUMMARY FOR OCTOBER 31, 2023

 

The strongest earthquake of the day was an M 6.6 in the region of Atacama, Chile. NEIC reported it was felt with maximum intensity VII in Atacama NEIC also reported it was felt with intensity VI in Copiapo with IV in Diego de Almagro and in La Serena, Coquimbo, Chile. An earthquake of M 5.4 preceded today's M 6.6 on October 26 and an M 5.9 on September 15, 2023. At the time this summary noted: At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 5.7-5.9 in the area off the coast of Atacama, Chile.  GUC reported this earthquake was felt with intensity  III in  Atacama at Copiapo, Tierra Amarilla and Caldera, Chile. This earthquake occurred with the new moon within about an hour of local solar noon and was probably promoted by tidal stresses associated with that alignment as described in previous issues of this summary:

 

Two strong earthquakes of M 5.9-6.0 struck the Atacama area of Central Chile today. They were felt with maximum intensity IX (local damage) at Vallenar; V in Vicuna and Ovalle, Coquimbo and IV in Coquimbo at Coquimbo, Copiapo, and IV in Valparaiso at Vina del Mar and Quilpue, Chile. ... The last earthquake of M>=6 within about 200 km of today's activity was a series on September 1, 2020 including events of M 6.8, 6.5 and 6.3 and prior to that an M 6.9 on November 11, 2015." (September 15, 2023, July 4, 2021, April 4, 2023)

 

Forecasts 157954 and 157681 had expected today's activity in Atacama, Chile was likely within about 50 km at the end of October or early November.

An M 6.5 occurred about an hour earlier than the event in Chile in the region of the Fiji Islands. NEIC reported it was lightly felt in Fiji at Levuka. It is likely that the Chile earthquake was triggered by seismic energy from this event in Fiji. Surface waves from Fiji - about 96 degrees away from Chile would have arrived about a hour later in Chile and could have helped trigger the Chilean event. Recent seismic activation of the Fiji region has included an M 5.5 on October 28 and an M 5.5 on October 23 and 22. At the time this summary noted:

 

"The strongest earthquake in the world today was an M 5.5 in the Fiji Islands. It was not reported felt in this remote area. The last earthquake in the Fiji Islands with equal or larger magnitude was an M 5.7 on September 5. The last within about 200 km of today's epicenter was an M 6.0 on July 24, 2023. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 6.0 in Tonga. This appears to break the current global seismic lull. As it occurred at a deep focus, it was not felt on the surface. It follows enhancement in the region

 

...

 

The last earthquake within about 200 km of today's epicenter in Fiji occurred on April 28, 2023 with M 6.6.  Further enhanced seismicity is likely in the Tonga/Fiji/Vanuatu area over the next several days with this regional seismic enhancement." (July 24, 2023)

 

Further regional enhancement is expected following today's earthquake" (October 23, 2023)

 

Forecasts 157947 and 157676 had expected today's event within about 50 km  at the end of October or early November, 2023.

An unusual earthquake of M 5.1 also occurred today in Sudan.  NEIC reported this earthquake of M 4.8 in Sudan was felt with intensity II-III in the area(s) of southern Sudan in Juba. This is the largest earthquake within about 200 km of this epicenter in Sudan since an M 5.4 on March 29, 1991. Two major earthquakes of M 7.2 and M 7.1 hit this region about 150 km north of today's epicenter on  May 20, 1990 and May 24, 1990. The history section of this summary described these events as:

 

"Some buildings were damaged in the Juba, Sudan area. Also some damage in the Mayo area, Uganda. Felt in the Nakura area, Kenya and to the north." (May 20, 2023)

 

Forecast 157712 had expected enhanced seismicity in this area was likely around November 2, 2023.

A series of moderate earthquakes also occurred today in the area from Nepal to Iran. This area saw the maximum lunar eclipse of October 28 as reported in previous issues of this summary:

 

"The full moon arrived on October 28, 2023 at 20:24 UT. Longitudes which were near local solar midnight at this time are near 50 East while those at local solar noon are near 130 West. In the east these include areas of Iran and the horn of Africa and in the east much of western North America including the area from California north to British Columbia and southeastern Alaska. These are the areas most likely to see tidally enhanced seismicity within a week of this full moon. This full moon is nearer the earth with high tidal stresses and will be accompanied by a lunar eclipse. This is a partial eclipse which will be fullest in the area of Yemen and Ethiopia at local midnight. It will also be visible in eastern U.S. at moonrise and throughout most of Africa, Asia and Europe maximizing in western Afghanistan, Iran, and the Gulf of Aden and Ethiopia. The eclipse will maximize at 20:15 UT. The last Saros series lunar eclipse occurred on October 17, 2005. It occurred within days of the M 7.5 in Pakistan and India of October 8, 2005 which killed more than 100,000 people. Earthquakes nearer the eclipse time included strong events in the Marshall Islands, Sumatra, Southern California, Western Turkey, Taiwan (M 7.0), Tokyo, Japan (M 6.6) and Fiji.  A strong earthquake is likely to accompany or to follow several days after the eclipse in this region. This is the 11th lunar eclipse in the Pharos series which began in 1843." (October 24-30, 2023)

 

The activity in India near Nepal continued elevated activity in that region of the past several days which included an M 5.3 on October 22, 2023 and an M 5.7 on October 3, 2023. This was reported at the time as:

 

 

"A moderately strong earthquake of M 5.7 hit the region of Nepal today. NEIC reported it was felt with maximum intensity VIII (with damage) in Amargadhi, Nepal and wiht II in Nepal and Dhangadhi, Nepalganj, Banke, Dailekh and in Uttaranchal, India at Pithoragarh, Bageshwar, Bhowali, Haldwai cum Kathgodam, Nainital. A foreshock of M 4.9 about 30 minutes before the mainshock was felt with intensity V in Nepal at Dhangadhi, Birendranagar, and in Uttaranchal, India at Nainital, and in Uttar, Pradesh, in Bareli, Lakhimpur, Rudraprayag, Moradabad, and Auras. NEIC reported an aftershock of M 4.8 in  Uttaranchal, India was felt with intensity II-III in the area(s) of  Uttaranchal, India in Kotdwara. A similar M 5.7 hit this region of Nepal on January 24, 2023 and today's activity may be considered aftershocks of that but a stronger M 6.3-6.6 hit the region on November 8, 2022. At the time of the event in January, 2023 this summary noted:

 

"The strongest earthquake felt in the world today was an M 5.6-5.7 in Nepal. NEIC reported it was felt with maximum intensity V inDipayal, Doti, Nepal with IV in Kichha, Uttaranchal, India. Intensity II-III was also felt in Nepal in Tansen, Palpa, and Pokhara, Kashi. In India this earthquake was felt with intensity II-III in Uttaranchal at Almora, Clement Town, and in Uttar Pradesh at Lakhnau, Cawnpore, Dankaur and Ghaziabad among other communities. EMSC reported light to moderate shaking in Nepal at Simikot, Birendranagar, Dhangadhi, Kohalpur, Kanchanpur, Pokhara, and in India at Pithoragarh, Almora, Haldwani, Pilibhit, Bhikia Sain, Shahjahanpur among other communities. This is the strongest earthquake in Nepal within about 200 km of this epicenter since an M 6.0 on September 25, 2008 and an M 6.2 on April 7, 2005 and July 11, 2004, the only such events in Nepal in the past 35 years.  " (October 3, 2023, January 24, 2023)

 

An M 5.6 hit Nepal a year ago on November 8, 2022 about the same time of day as today's event of M 4.1. It is likely further moderate to large earthquakes will occur in Nepal in the coming week. Forecast 157521 had expected today's activity in Nepal was likely in late October.

The strongest earthquake in the U.S. or Canada today was an M 4.0 in the Kenai Peninsula, Alaska. The M 4.0 is the strongest earthquake in the Kenai Peninsula since an M 4.8 on April 10, 2023 and an M 5.4 on March 19, 2023. At the time this summary noted in this regard:

 

"The strongest earthquake in the U.S. or Canada today was an M 4.6-4.8 in Kenai, Alaska. NEIC reported it was felt with intensity II-III in Alaska at Kenai, Anchorage, Sterling, among others.  This is the strongest earthquake in the Kenai Peninsula since an M 5.4 about 200 km southwest of this on March 19, 2023. At the time this summary noted:

 

 

"The last earthquake of larger magnitude within about 200 km of today's event  occurred about 50 km south of today's epicenter on January 24, 2016 with M 7.1 and prior to that an M 6.2 on July 29, 2015. Both of these events were associated with strong solar outbursts. Today's earthquake occurred within minutes of local solar noon (like the M 7.2 in Northern California yesterday) and was likely promoted by strong tidal and geomagnetic stresses which maximize near this hour." (April 10, 2023, December 21, 2021)

 

 

NEIC reported this earthquake of M 3.0 in Kenai Peninsula, Alaska was felt with intensity II-III in the area(s) of Kenai Peninsula, Alaska in Homer, Anchor Point.  NEIC reported this earthquake of M 4.0 in Southern Alaska was felt with intensity II-III in the area(s) of Southern Alaska in Point Possession (IV),   Today's earthquake occurred near local solar noon and may have been promoted by tidal stresses which maximize near this hour.

A light earthquake of M 2.5 hit the Mount Hood area of Oregon today. This may be related to volcanic activity at this northwestern U.S. volcano. The last earthquake of M>=2.5 in the Mount Hood area was an M 2.5 on October 18, 2021 and an M 4.0  on June 6, 2021. At the time this summary noted:

 

 

"An unusually large M 3.9-4.0 earthquake shook the Mount Hood area of Oregon today. NEIC reported intensity IV in Oregon at Government Camp, Rhododendron, and Cascake Locks, Oregon with III in Mount Hood, Parkdale, Welches, Brightwood, Hood River,  Sandy, Mosier and Estacada. It was followed by aftershocks of M 2.1 and 2.4 and may represent subterranean volcanism in the area. The only earthquake in the past 30 years in the Mount Hood area of Oregon with M>=4 was an M 4.5 on June 29, 2002." (June 6, 2021)

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 JAMAICA

 

EARTHQUAKE SUMMARY FOR OCTOBER 30, 2023

 

 

A moderately strong earthquake of M 5.4-5.5 shook much of the island of Jamaica today. NEIC reported maximum shaking with intensity VIII in Jamaica at Mona, Kingston, Above Rocks, Saint Catherine; VI in Kingston, Half Way Tree, Constant Spring an dHope Bay, Portland and V in Port Antonio, Stony Hill, Gordon Town and Anotto Bay, Saint Mary, Saint Andrew. It was reported felt as far as Montego Bay, Saint James, Jamaica and in Santiago de Cuba, Cuba. This is the strongest earthquake in Jamaica within about 200 km of this epicenter since an M 5.8 on January 17, 2017.  At the time of this event this summary noted:

 

"The largest earthquake in the world today was an M 5.8-5.9 in Cuba. This event was reported felt with intensity VI in Guisa, Cuba and II in Guantanamo. In Jamaica intensity IV was felt in Ocho Rios and II-III in Spaldings, Half Way Tree, Saint Andrew, and Montego Bay, Saint James. The last earthquake within about 200 km of this epicenter with M>=5.8 was an on May 25, 1992 with M 6.8, a month before M 7.5 in Landers, Southern California. Forecast 104360 had expected this earthquake was possibly around January 20 to the west of this epicenter. Cuba is not a highly seismic area and the occurrence of this event at this time may be related to the general activation of the northern Caribbean" (January 17, 2017)

 

Two moderate earthquake have occurred in Jamaica in the past three years - an M 4.3 on September 22, 2023 and an M 4.6 on April 15, 2023.

 

Today's event may have been promoted by a tropical cyclone nearby as noted in this summary:

 

"A tropical cyclone may be forming south of the Puerto Rico in the Caribbean. This system is currently located near 17N 67W and likely to track to the west. Some effect on regional seismicity in the area from Puerto Rico to Jamaica and later in Central America is expected with this system which NHC expects could become a Tropical Depression in the next two days with 30% likelihood." (October 30-31, 2023)

 

Forecast 157775 had expected today's event to the northeast was likely in early November.

A moderate earthquake of M 4.6 also occurred in the Dominican Republic north of Jamaica today. The last earthquake of equal or larger magnitude in the Dominican Republic was a similar M 4.6 on March 13, 2023 but the last event of larger magnitude in the Dominican Republic occurred on February 1, 2023. At the time this summary noted:

 

 

"A moderate earthquake of M 5.0 shook regions of the Dominican Republic today. NEIC reported maximum intensity V in the Dominican Republic at Matanzas, Pizarrete, San Cristobal, IV in Bani, Sabana Buey (VI), Bajos de Haina, El Carril, San Jose de Ocoa and Santo Domingo with lesser shaking throughout most of the Dominican Republic.

Local news reported it initially with M 5.3-5.6. It occurred on the Enriquillo-Plantain Garden fault south of Santo Domingo and was most strongly felt from Barahona to Santo Domingo and Santiago. It was also felt as far as the Bahamas, Turks and Caicos Islands, Haiti and Puerto Rico. Widespread panic accompanied the earthquake and some businesses evacuated employees. Structural damage was reported in three schools in the Matanzas area. This included cracks and fallen plaster and ceiling tiles. Classes were suspended for the day. The last earthquake with M>=5.0 in the Dominican Republic and within about 200 km of today's epicenter was an M 5.2 about 200 km northwest of this epicenter on September 23, 2018. The last similar event was an M 5.1 on July 7, 2012 - an aftershock of an M 5.5 on January 5, 2012." (February 1, 2023)

 

Forecast 157513 had expected today's event was likely within about 75 km around October 28.

The strongest earthquake in the U.S. or Canada today was an M 4,3 north of the Fox Islands in the Pribilof Islands. It was not reported felt in this remote area. The only event reported by NEIC in the past year was an M 4.8 on September 27, 2023. Before that an M 4.7 occurred on October 26, 2022. Forecast 157905 had expected regional seismic enhancement was likely in early November, 2023.

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 MAY PRECEED ENHANCED GLOBAL SEISMICITY

 

EARTHQUAKE SUMMARY FOR OCTOBER 29, 2023

 

It was a relatively quiet day in global seismicity today. Several factors favor an increase in global seismicity over the next several days. This increased seismicity is likely to include several large earthquakes near the geomagnetic equator or at high latitudes. These include lingering effects of the full moon and lunar eclipse of October 28 as well as effects associated with the strong geomagnetic storm which peaked today with high latitudes showing a major storm with AP 49 today and 86 yesterday. This is the strongest geomagnetic storm at high latitudes in more than a year – since AP reached 91 on September 4, 2022. Expected seismicity related to this storm was reported in this summary as:

 

"The geomagnetic field saw minor storm  conditions today. The AP level was 28.  High latitudes  saw major storm conditions with AP 49. Middle latitudes were at active conditions with AP 21. The strong storm at high latitudes is likely to enhance seismicity in that region and most of the rest of the world - especially near the geomagnetic equator - in the next several days." (October 30, 2023)

 

The strongest earthquake today in the U.S. or Canada was an M 4.2 in the eastern Andreanof Islands, Aleutians, Alaska. It was not reported felt in this remote area. The last event of stronger magnitude in the eastern Andreanof Islands was an M 4.5 on August 6, 2023. Forecast 157634 had expected today's event within about 50 km was likely around October 30.

The strongest earthquake in the world today was an M 5.1 in the northern Mid-Atlantic Ridge. The last earthquake within about 200 km of this epicenter with equal or greater magnitude was an M 5.6, 5.2 and 5.1 about 150 km north of this on June 23, 2023. At the time this summary noted:

 

 

"The strongest seismicity in the world today was a series of moderate to moderately strong events in the Northern Mid-Atlantic Ridge. The largest of these was M 5.6 but others of M 5.2, 5.1 and 5.0 were also recorded. These events were not reported felt in these epicentral areas. This swarm began within minutes of local solar noon with an M 5.0 and 4.5 and were probably promoted by strong tidal stresses which maximized at this hour. Two earthquakes have been recorded within about 300 km of today's events with M>=5.6 in the past 35 years - an M 5.6 on August 31, 2011 and an M 5.9 on March 28, 2021." (June 23, 2023)

 

Today's event also occurred within several minutes of local solar noon and was likely promoted by strong tidal stresses which maximize near this hour.

 

Forecast 157614 had expected today's event within about 100 km was likely in late October.

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 6.9 in the area of New Guinea October 7, 2023, where promoted seismicity is considered likely.

Today's projected seismicity map follows for the coming week.

 

 

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 VANUATU QUAKE TRIGGERED BY TROPICAL CYCLONE LOLA

 

EARTHQUAKE SUMMARY FOR OCTOBER 28, 2023

 

The strongest earthquakes in the world today were an M 6.0 and M 5.6 in Southern Vanuatu. NEIC reported it was felt with intensity VI in Vanuatu at Isangel and III in Vila Shefa with II-III in New Caledonia at We Iles, and Noumea. This was likely promoted by the passage of a strong Tropical Cyclone (Lola)through the area over the past several days as noted in previous issues of this summary:

 

"Tropical Cyclone Lola (01P) continued over central  Vanuatu today with winds up to 35 kts. This system is moving to the south and west. Some increases in seismicity in Vanuatu likely with this storm including a possible strong regional earthquake in the next three days." (October 25-28, 2023)

 

Today's M 6.0 in southern Vanuatu is the strongest since events of M 6.0-6.1 on September and September 21, 2023. At the time this summary noted in this regard:

 

 

“The strongest earthquake of the day in the world was an M 6.1 in northern Vanuatu. NEIC reported it was felt with intensity IV in Luganville, Sanma, Vanuatu. This may be an aftershock of an M 6.5 which occurred on August 16, 2023. At the time this summary noted in this regard:

 

"The strongest earthquake in the world today was an M 6.5 in northern Vanuatu. The mainshock was reported by NEIC to have been felt with intensity VII in Vanuatu at Sola Torba and IV in Sanma at Port Olry and Luganville and possibly in the Solomon Islands and New South Wales, Australia. The mainshock was preceded by an M 5.2 regional foreshock several hours earlier. That event was

felt with intensity III in Luganville, Sanma, Vanuatu. An aftershock of M 4.3 was felt with intensity IV in Port Olry, Sanma, Vanuatu. The mainshock within minutes of local solar midnight and most likely was promoted by tidal stresses with the new moon which was completed within hours of the occurrence of this earthquake.

 

...

 

Today's event of M 6.5 is the largest in northern Vanuatu since an M 7.0 about 150 km south of this epicenter on January 8, 2023. The last within 100 km at this magnitude level was an M 6.6 on January 15, 2019. (September 21, 2023, August 16, 2022)

 

Forecasts 157677, 157682 and 157678 had expected today's activity in Vanuatu was likely in late October.

Several aftershocks in western Afghanistan also occurred today. NEIC reported these earthquakes of M 5.0 and M 4.8 in Western Afghanistan were felt with intensity IV-VI in the area(s) of Western Afghanistan in Herat at Karokh (VI) and Herat (IV) and in Taibad, Khorasan Iran and Kabul, Afghanistan. The strongest of these - the M 5.0 occurred within minutes of the maximum full moon and eclipse today and was probably promoted by tidal stresses associated with  that alignment as noted in previous issues of this summary:

 

"The full moon will arrive on October 28, 2023 at 20:24 UT. Longitudes which are near local solar midnight at this time are near 50 East while those at local solar noon are near 130 West. In the east these include areas of Iran and the horn of Africa and in the east much of western North America including the area from California north to British Columbia and southeastern Alaska. These are the areas most likely to see tidally enhanced seismicity within a week of this full moon. This full moon is nearer the earth with high tidal stresses and will be accompanied by a lunar eclipse. This is a partial eclipse which will be fullest in the area of Yemen and Ethiopia at local midnight. It will also be visible in eastern U.S. at moonrise and throughout most of Africa, Asia and Europe maximizing in western Afghanistan, Iran, and the Gulf of Aden and Ethiopia. The eclipse will maximize at 20:15 UT. The last Saros series lunar eclipse occurred on October 17, 2005. It occurred within days of the M 7.5 in Pakistan and India of October 8, 2005 which killed more than 100,000 people. Earthquakes nearer the eclipse time included strong events in the Marshall Islands, Sumatra, Southern California, Western Turkey, Taiwan (M 7.0), Tokyo, Japan (M 6.6) and Fiji.  A strong earthquake is likely to accompany or to follow several days after the eclipse in this region. This is the 11th lunar eclipse in the Pharos series which began in 1843." (October 23-24, 2023)

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 IN SOUTHEASTERN ALASKA WITH FULL MOON, LUNAR ECLIPSE

 

EARTHQUAKE SUMMARY FOR OCTOBER 27, 2023

 

 

A series of earthquakes occurred today in southeastern Alaska. The largest of these were of M 5.1 and M 5.3. NEIC reported it was felt with maximum intensity IV in Alaska at Haines and Hoonah and II-III in Skagwaym Elfin Cove, Douglas, Juneau, Sitka, and Angoon and in Whitehorse, Yukon, Canada and Fraser Lake, British Columbia, Canada and perhaps as far as Anchorage and Beaver, Alaska nearly 1000 km to the north. Aftershocks were felt with intensity II-III in Southeastern Alaska at Elfin Cove, Douglas, Juneau and in Whitehorse, Yukon, Canada. It is likely these events were promoted by tidal stresses with today's full moon and eclipse as noted in previous issues of this summary as:

 

"The full moon will arrive on October 28, 2023 at 20:24 UT. Longitudes which are near local solar midnight at this time are near 50 East while those at local solar noon are near 130 West. In the east these include areas of Iran and the horn of Africa and in the east much of western North America including the area from California north to British Columbia and southeastern Alaska. These are the areas most likely to see tidally enhanced seismicity within a week of this full moon. This full moon is nearer the earth with high tidal stresses and will be accompanied by a lunar eclipse. This is a partial eclipse which will be fullest in the area of Yemen and Ethiopia at local midnight. It will also be visible in eastern U.S. at moonrise and throughout most of Africa, Asia and Europe maximizing in western Afghanistan, Iran, and the Gulf of Aden and Ethiopia. The eclipse will maximize at 20:15 UT. The last Saros series lunar eclipse occurred on October 17, 2005. It occurred within days of the M 7.5 in Pakistan and India of October 8, 2005 which killed more than 100,000 people. Earthquakes nearer the eclipse time included strong events in the Marshall Islands, Sumatra, Southern California, Western Turkey, Taiwan (M 7.0), Tokyo, Japan (M 6.6) and Fiji.  A strong earthquake is likely to accompany or to follow several days after the eclipse in this region. This is the 11th lunar eclipse in the Pharos series which began in 1843." (October 23-24, 2023)

 

Today's event in southeastern Alaska is the strongest within about 250 km of this epicenter since an M 6.2 and 5.3 on May 1, 2017 followed by aftershocks of M 5.6 and 5.7. At the time this summary noted in regard to this series:

 

" ... The only moderate seismicity in this year (2017) in the area prior to today occurred on January 16 with M 4.1 and 4.3. An M 6.2 hit the are 17 years ago on January 6, 2000. The M 6.3 in this region today is the strongest within about 200 km of this epicenter since an M 6.7 on July 1, 1973. Other events of M>=6.3 were recorded on July 10, 1958 (M 7.9); February 3, 1944 (M 6.4); October 24, 1927 (M 7.1); January 18, 1901 (M 7.1) and in September, 1899 (M 8.6). A strong aftershock is considered likely since it has been 44 years since the last such event in the region." (May 1, 2017)

 

Forecast 157646 had expected today's activity within about 25 km was likely

in late October between October 22 and 28, 2023.

A light M 2.9 in Northern California south of the San Francisco Bay area occurred following the M 5.1 in SE Alaska and may have been triggered by it. The California quake was reported by NEIC to have been felt with intensity II-III in San Jose, Santa Clara, Los Gatos, Mountain View, Boulder Creek, Walnut Creek and San Francisco. This activity occurred during a minor geomagnetic storm in conjunction with the full moon and lunar eclipse today and was probably promoted by stresses associated with those two factors. The last earthquake in San Francisco of similar size was an M 3.6 on December 17, 2022. At the time this summary noted:

 

 

"Today's event of M 3.6 is the strongest within the San Francisco Bay area of

California within about 50 km of this epicenter since an M  M 4.1 on June 2, 2022 and prior to that an M 3.9 on June 20, 2021 and an M 4.5 on October 15, 2019. At the time of the last such event on June 2, 2022, this summary noted:

 

 

"An earthquake of M 4.2 also shook the region of San Francisco, California today. NEIC reported maximum intensity IV in Sulsun City with intensity III throughout most of the rest of the San Francisco Bay area including at Concord, Benicia, Pittsburg, Birds Landing, and Pleasant Hill among others. This is the strongest earthquake in the San Francisco Bay area of California since an M 4.5 on October 15, 2019 and prior to that, events of M 4.2-4.3 on July 16, 2019 and January 4, 2018. The last earthquake of significantly larger magnitude in the San Francisco Bay area was an M 6.0 in the Napa area on August 24, 2014. These are the only events of M>=4.2 in the San Francisco area in the past 13 years." (December 17, 2022, June 2, 2022)

 

Forecast 157538 had expected today's activity in  San Francisco was likely within about 50 km in late October.

NEIC reported earthquakes of M 3.4 and M 4.2 in Central California were felt with intensity II-III today in the area(s) of Central California in Topaz,  Coleville (IV), Bridgeport, Markleeville, South Lake Tahoe, and in Nevada in Wellington, Smith, Gardnerville, Minden, Yerington and Glenbrook among others.  An aftershock of M 2.8 was felt with intensity III in Gardnerville, Nevada. The last earthquake within about 100 km of this epicenter in Central California with equal or greater magnitude was an M 4.5 on August 8, 2022. These are aftershocks of an M 6.0 of July 8, 2021. In August, 2022 this summary commented:

 

 

"The M 4.4-4.6 on the border between Central California and Nevada today occurred within minutes of local solar noon and was probably promoted by high tidal/geomagnetic effects which maximize near this hour as well. NEIC reported it was felt with intensity II-III in California at Topaz, Coleville, Gardnerville, Markleeville, Bridgeport and in Nevada at Wellington, Smith, Gardnerville, Minden among others. NEIC reported aftershocks of M 2.5-3.5 in Central California were felt with intensity II-III in the area(s) of  in Carson City, Nevada. The M 4.4-4.6 is the strongest aftershock of the M 6.0 which shook the area on July 8, 2021 since that date.  Forecasts 145565 and 145563 had expected today's activity within about 25 km of this epicenter in early August." (August 8, 2022)

 

Forecast 157536 had expected today's activity was likely within about 30 km

around October 26.

A major swarm of moderate earthquakes occurred off the coast of Chiapas, Mexico today. Most of these followed an M 4.7 mainshock but a foreshock of M 4.1 was also recorded. The total solar eclipse of October 14 was visible in Chiapas around 17:15 UT and may have helped trigger today's activity. A series of foreshocks began shortly after the solar eclipse and included an M 5.0 on October 21 and an M 4.9 on October 20, 2023. These may be regional aftershocks of an M 6.3 in Chiapas which occurred on July 14, 2023.  Forecast 157493 had expected today's activity within about 100 km was likely around October 29.

The strongest earthquakes in the world today continued the seismic activation of the Southwestern Pacific region. These occurred with M 5.5 in the Solomon Islands and another of M 5.5 in the Fiji region where several moderate size

earthquakes have occurred in the past few days including an M 5.5 on October 23 and an M 5.5 on October 22. This is an active region and is likely to see additional event of strong magnitude through the end of October. Forecast 157687 had expected today's event within about 50 km was likely around October 25.

"A moderate earthquakes also shook the region of Guadalcanal, Solomon Islands today where NEIC reported it was felt with intensity IV in Honiara. This appears to be an aftershock of an M 6.1 of May 21, 2023. At the time this summary noted in this regard:

 

 

"A strong M 6.1 was also felt in the Solomon Islands today. NEIC reported it was felt with intensity V in the Solomon Islandsa at Kirakira Makira and Ulawa and in Honiara, Guadalcanal. This is part of a regional enhancement of seismicity following the M 7.7 and 7.2 events in the Loyalty Islands of the past two day which occurred about 15 degrees south east of this epicenter in the Solomon Islands. Today's event of M 6.1 is the strongest in the Solomon Islands within about 200 km since an M 6.3 on January 27, 2020 and an M 6.5 on September 9, 2018." (May 28, 2023, May 21, 2023)

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.

FULL MOON BRINGS ENHANCED SEISMICITY TO OCEAN RIDGES

 

EARTHQUAKE SUMMARY FOR OCTOBER 26, 2023

 

The full moon and lunar eclipse will arrive on October 28 as noted in this and previous summaries:

 

"The full moon will arrive on October 28, 2023 at 20:24 UT. Longitudes which are near local solar midnight at this time are near 50 East while those at local solar noon are near 130 West. In the east these include areas of Iran and the horn of Africa and in the east much of western North America including the area from California north to British Columbia and southeastern Alaska. These are the areas most likely to see tidally enhanced seismicity within a week of this full moon. This full moon is nearer the earth with high tidal stresses and will be accompanied by a lunar eclipse. This is a partial eclipse which will be fullest in the area of Yemen and Ethiopia at local midnight. It will also be visible in eastern U.S. at moonrise and throughout most of Africa, Asia and Europe maximizing in western Afghanistan, Iran, and the Gulf of Aden and Ethiopia. The eclipse will maximize at 20:15 UT. The last Saros series lunar eclipse occurred on October 17, 2005. It occurred within days of the M 7.5 in Pakistan and India of October 8, 2005 which killed more than 100,000 people. Earthquakes nearer the eclipse time included strong events in the Marshall Islands, Sumatra, Southern California, Western Turkey, Taiwan (M 7.0), Tokyo, Japan (M 6.6) and Fiji.  A strong earthquake is likely to accompany or to follow several days after the eclipse in this region. This is the 11th lunar eclipse in the Pharos series which began in 1843." (October 24-27, 2023)

 

This is accompanied by a moderate geomagnetic storm today. The two probably

helped promoted enhanced global seismicity - especially in Oceanic areas - adding about 0.5 magnitude units to the largest events. Moderately strong earthquakes were recorded with an M 5.9 in the area west of Macquarie Island and nearby an M 5.6 in the Balleny Islands area. These were not felt. The Balleny Islands event is antipodal to the increase is Icelandic seismicity today – which also continued unabated. Today's high latitude seismicity was likely  also promoted by a moderate geomagnetic storm with AP of 29 at high latitudes.

The earthquake of M 5.6 in the Balleny Islands was the largest within about

250 km of the epicenter since an M 5.8 on August 23, 2022. An earthquake of M 5.9 also hit the Balleny Islands about 350 km from today's event on July 6, 2023 also in conjunction with enhanced seismicity in Iceland as reported in this summary at the time:

 

 

"The volcanic swarm of earthquakes in Iceland continued today near Reykjavik where many of the moderate quakes in this swarm were felt today. A volcanic warning has been issued by Icelandic authorities as more than 2000 light to moderate quakes have occurred in this region in the past two days.

...

 

 

The strongest earthquake of the day occurred near the antipode of the tremors in Iceland. This event of M 5.9 in the Balleny Islands was not reported felt in this remote epicentral area. This event occurred simultaneously with Solar Flare 7970, the strongest solar of the day and was probably promoted by Solar Flare Effects (SFE) associated with that flare." (July 6, 2023)

 

Today's event in the Balleny Islands occurred two minutes after the start of Flare 7800 and may have been promoted by SFE from the flare (See Flare listing below).

 

The M 5.9 in the Macquarie Island area is the largest within about 250 km of that event since an M 6.1 on March 20, 2021. At the time this summary noted:

 

"The last earthquake in the Macquarie Islands within about 300 km of today's epicenter with M>=6.1 occurred on February 27, 2018 wih M 6.1, The last of larger magnitude was an M 6.6 on October 9, 2012." (March 20, 2021)

An earthquake of high latitudes also occurred today in the Komandorsky Islands of Russia with M 5.9. This is the strongest earthquake in the Komandorsky Islands since an M 6.0 on September 20, 2022, the only such event in the past 3 years. At the time this summary noted:

 

 

"The strongest earthquake in the world today was an M 6.0 in the Komandorsky Islands, Alaska. It may have been lightly felt as far as Alaska. The last earthquake of larger magnitude than M 6.0 in the Komandorsky Islands occurred as an M 6.6 to the west of today's event on March 16, 2021." (September 20, 2023)

 

The earthquake in the Komandorsky Is, as well as those in the Balleny and Macquarie Island region today were at the sixth node (60 degrees) from the M 6.8 in New Guinea of October 7 and may have been promoted by energy from that source. Forecast 157638 had expected today's event in the Komandorsky Islands within about 25 km was likely around October 27.

An M 5.1 occurred today in Eastern Iran.  NEIC reported this earthquake of M 5.1 in Southern Iran was felt with intensity II-III in the area(s) of Southern Iran in Birdjand, Khorasan.  This occurred within minutes of local solar midnight and was probably promoted by the full moon of October 26 which will maximize over this epicenter (see Tidal forecast in this summary). Forecast 157544 had expected today's event to the northeast was likely around October 21.

Enhanced seismicity also continued today in the southwestern Pacific today. This included an M 5.6 in Tonga and an M 5.2 in the Loyalty Islands south of Vanuatu. This event was probably promoted by Tropical Cyclone Lola, a major storm which was passing through this area when this event occurred as noted in this and previous issues of this summary:

 

"Tropical Cyclone Lola (01P) continued over central  Vanuatu today with winds up to 35 kts. This system is moving to the south and west. Some increases in seismicity in Vanuatu likely with this storm including a possible strong regional earthquake in the next three days." (October 24-26, 2023)

 

Forecasts 157675 had expected the event in Tonga was likely in late October while forecast 157682 had expected the event in the Loyalty Islands was likely around October 27.

The strongest earthquake in the U.S. or Canada today was an M 4.1 near Hudson Bay in the Clyde River area of Nunavut, Canada. This is the largest earthquake in this region within about 200 km of this epicenter since an M 4.5 on November 19, 2022 and an M 4.3 on September 26, 2021. In the past 15 years there have been 10 events in this region of M>=4.1 - most - 7 of the 10 have occurred in the period August through November suggesting a seasonal bias, perhaps related to melting ice.

 

Forecast 157661 had expected enhanced activity in this area was likely around October 28.

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 6.9 in the area of New Guinea October 7, 2023, where promoted seismicity is considered likely.

 

Today's projected seismicity map follows for the coming week.

 

 

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.
