MODERATELY STRONG QUAKE SHAKES CENTRAL CHILE WITH RENEWED GEOMAGNETIC STORM

 

EARTHQUAKE SUMMARY FOR AUGUST 17, 2022

 

A moderately strong earthquake of M 5.3-5.5 occurred in Central Chile today. This event in O'Higgins, Chile was felt with maximum intensity IV in Machali, Rancagua, Graneros, O'Higgins and in Metropolitana at Paine, Puente Alto, Talagante with lesser shaking in El Monte, San Bernardo, Rengo. GUC reported this earthquake was felt with  VI in   Santiago at Maipu, Puente Alto, San Bernardo, San jose de Maipo; V in Buin, Calera de Tango, Cerrilos, El Monte, La Reina, Las Condes, Macul, Maria Pinto, Melipilla, Nunoa, Paine, Penalolen, Pudahuel, Quilicura, San Juaquin, Santiago, Talagante,  in O'Higgins with maximum intensity V in Rancagua, Pichilemu, Navidad, Chimbarongo, La Estrella, Machali, Mostazal; in Maule and Nuble with V in Hualane, II in Chillan and Ninhue, in Valparaiso with V in Casablanca, Valparaiso; and Coquimbo with IV in Illapel, Chile. This is the strongest earthquake within about 200 km of this epicenter in Central Chile since an M 5.5 more than a year ago with an M 5.5 on April 22, 2021. The last event of larger magnitude in this area was an M 5.8 on January 24, 2021 and an M 6.8 on August 1, 2019. Today's event may be a regional aftershock of the M 6.8 in 2019.  Forecasts 145959 and 145960 had expected today's seismic enhancement in central Chile was likely in mid-August. It occurred near local solar midnight and immediately followed the maximum of a severe geomagnetic storm as noted in this summary as:

 

"The geomagnetic field saw stormy conditions today. The AP level was 31. High latitudes also saw  active conditions with AP 17. A strong geomagnetic storm is likely in the next two days bringing fresh seismic enhancement.  A major solar flare with this activity could trigger a major earthquake at this time. A series of three M-class solar flares occurred today possibly leading to enhanced geomagnetic activity in the next several days and induced seismicity at that time.  These are the largest M-class flares recorded by SWPC since July 16, a month ago." (August 17-18, 2022)

An earthquake of M 5.6 also occurred about 10 degrees south of the geomagnetic equator in Indonesia today. It occurred at a deep focal depth and was not reported felt on the surface.  Like activity in the area over the past day, this was probably related to the current geomagnetic storm as noted in previous issues of this summary:

 

"Following strong geomagnetic storms, in the several days after they settle down, ring currents set up at about 10 degrees either side of the geomagnetic equator. These ring currents induce telluric electric currents in the earth below them. These, in turn, change the electrical environment in these areas and help to enhance seismicity in these areas. Global seismicity today showed this pattern. A series of moderately large to large earthquakes today occurred near 10 degrees from the geomagnetic equator. These events of M 5.7-5.9 are of a magnitude, location and timing suggesting they were promoted by this induction effect. They occurred as an M 5.9 in Papua New Guinea; an M 5.7 in the Molucca Sea of Indonesia and an M 5.8 and 5.9 in central Vanuatu. Triggering of this type is expected to continue for another day with strong earthquakes possible, especially in the southwest Pacific during the next several days." (August 15, 2022)

 

 

Forecast 145743 had expected today's event within about 200 km was likely between August 16 and 20. This event is at 146 degrees from the M 6.8 in Argentina of May 10, 2022 and may have been promoted by energy from that source.

Seismicity off the eastern coast of Honshu, Japan continued at elevated levels today. This is probably related to the geomagnetic storm today as had been noted in the previous issue of this summary:

 

"The strongest seismicity in the world today occurred in the region of the Kuril Islands and the Izu Islands, Japan. The Kuril Islands saw an M 5.4 and aftershocks of M 5.0, 4.9 and 4.8 while the Izu Islands event was M 5.3. These are areas which often see enhanced seismicity at times of high solar/geomagnetic activity." (August 17, 2022)

 

 

NEIC reported the earthquake of M 5.1 in Honshu, Japan was felt with intensity II-III in the area(s) of Honshu, Japan in Miyagi, Ibaraki, Chiba, Saitama Prefectures.  NEIC reported the earthquake of M 4.8 in Southeastern Honshu, Japan was felt with intensity II-III in the area(s) of Southeastern Honshu, Japan in Ibaraki and Tokyo Prefectures. Forecasts 145833 and 145847 had expected this activity in mid-August. This event is at 144 degrees from the M 7.2 in Southern Peru of May 26, 2022 and may have been promoted by energy from that source.

The strongest earthquake in the U.S. or Canada today was an M 3.8 in the Yukon Territory of Canada. It was not reported felt in this remote epicentral area. The last earthquake within about 200 km of this epicenter of M>=3.8 occurred on  October 29, 2021 with M 3.9 and June 11, 2021 with M 3.8.  Forecasts 145928 and 145929 had expected today's event in the Yukon Territory was likely around August 16-18.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

MAJOR GEOMAGNETIC STORM AND SOLAR FLARE MAY BRING STRONG TO MAJOR EARTHQUAKE

 

EARTHQUAKE SUMMARY FOR AUGUST 16, 2022

 

SWPC expected a major to severe geomagnetic storm today or August 18. This summary has noted the potential of such storms in this and previous issues of this summary as:

 

"The geomagnetic field saw quiet conditions today. The AP level was 5. High latitudes also saw  quiet conditions with AP 4. A strong geomagnetic storm is likely in the next two days bringing fresh seismic enhancement.  A major solar flare with this activity could trigger a major earthquake at this time. A series of three M-class solar flares occurred today possibly leading to enhanced geomagnetic activity in the next several days and induced seismicity at that time.  These are the largest M-class flares recorded by SWPC since July 16, a month ago.

 

and

 

The geomagnetic field is expected  to see  minor storms August 17, severe storms August 18 and major storms August 19. Solar activity is expected to be at quiet levels August 17-19 with a slight chance (30%) of an M-class flare and 10% chance of an X-class flare.  SWPC expects a proton storm with 10% likelihood likely towards the end of this period." (August 15-17, 2022)

 

A strong flare (#3800) of class M5.0 occurred at 07:52-08:05 UT today. This is the strongest flare recorded by SWPC since an M5.3 on May 4, 2022. Seismicity which may have been affected by SFE from this flare occurred about 30 minutes later as an M 5.0 in the Loyalty Islands and about an hour later at the anti-solar longitude at the time of the flare (122 W) as an M 3.1 in British Columbia. 

 

The strongest seismicity in the world today occurred in the region of the

Kuril Islands and the Izu Islands, Japan. The Kuril Islands saw an M 5.4 and aftershocks of M 5.0, 4.9 and 4.8 while the Izu Islands event was M 5.3. These are areas which often see enhanced seismicity at times of high solar/geomagnetic activity. The last earthquake within about 150 km of the Kuril Islands epicenter with M>=5.4 occurred as an M 5.6 on December 5, 2019 while the Izu Islands saw a series of moderate events of M 5-5.7 in late July and early August, 2022. Forecasts 145867 and 145832 had expected this activity within about 50 km was likely in mid-August. The activity in the Kuril Islands is at 144 degrees from the M 6.8 in Argentina of May 10 and may have been promoted by energy from that source.

The strongest earthquake in the U.S. or Canada today was an M 5.0-5.2 in the Alaska Peninsula. It was not reported felt in this epicentral area. The area had been expected to see enhanced seismicity at this time due to its antipodal position from an M 5.3 south of Africa on August 14, 2022. At the time this summary commented in this regard as:

 

"A moderate earthquake of M 5.3 was recorded south of Africa today. This event is near the antipode of recent activity in the Alaska Peninsula and may promoted enhanced seismicity in that region." (August 14, 2022)

 

This is the strongest earthquake in the Alaska Peninsula within about 150 km of this epicenter since an M 5.3 on February 20, 2022, the only larger aftershock in the area since the M 6.9 on October 11, 2011.  Forecast 145897 had expected today's event in this area was likely around August 14.

An earthquake of M 4.4 also occurred off the coast of northern California today. It was not reported felt in this area. The last earthquake within about 100  km of this epicenter with M>=4.4 occurred on June 4, 2021 (M 5.9 and 4.7) about 50 km northeast of today's epicenter.  Forecast 145884 had expected a moderate event within about 50 km of this epicenter around August 20.

NEIC reported these earthquakes of M 3.0 and M 2.5 in Maine were felt with intensity II-III in the area(s) of Maine in Jonesboro, Columbia Falls, Addison and Jonesport. A series of events hit this region east of Bar Harbor on August 11-13, 2022. This summary noted at the time:

 

"A series of light earthquakes occurred today east of Bar Harbor, Maine with M 3.1, 2.8 and 2.2.  Two earthquakes of M 2.8 and M 3.1 hit southeastern Maine today. NEIC reported they were felt with intensity II-III in Jonesboro, Columbia Falls, Machias and Addison. The M 3.1 is the strongest earthquake within about 100 km of this epicenter since an M 3.3 on February 2, 2016 and an aftershock to the north on February 9, 2016. This activity was probably promoted by high tides with today's full moon. Forecasts 145628 and 145871 had expected his activity within about 50 km of these epicenters was likely between August 5 and 13." (August 12, 2022)

 

This activity is at the sixth node (60 degrees) from the M 7.2 in southern Peru of May 26, 2022 and may have been promoted by energy from that source.

An earthquake of M 3.8 occurred in western Texas today. NEIC reported it was felt with intensity IV in Texas at Rotan, Loraine and II in Snyder and Anthony.  This epicenter is about 200 km to the east of the recent series of events near Pecos, Texas at 103 and 104 West longitudes and continues a growing number of events near this epicenter in recent days. This could indicate a new and potentially important addition to current Texan seismicity. Today's event of M 3.8 is the strongest within about 100 km of this epicenter since an M 4.0 on September 20, 2019. The area became active in September 11-12. 2011 with events of M 4.3 and 4.5 following foreshocks of M 3.8 on March 13, 2011 and August 8, 2010 (M 3.4). Forecast 145836 had expected today's event in this region was likely around August 19. This activity is at 101-102 degrees from the Loyalty Islands event of M 7.0 of March 31 and may have been promoted by energy from that source.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

MODERATE QUAKE IN ATLANTIC ON QUIET DAY

 

EARTHQUAKE SUMMARY FOR AUGUST 15, 2022

 

Following several days of active seismic conditions associated with the recent

geomagnetic storm, global seismicity today was at relatively quiet levels. The strongest earthquake of the day was an M 5.3 in the Central Atlantic near Ascension Island. This is the strongest earthquake in the region within about 300 km since an M 5.5 on June 11, 2022 and the second strongest  in the area in the past two years. Forecast 145751 had expected today's event in this area was likely around August 18.

The strongest earthquake felt in the world today was an M 5.2-5.4 in southern Mindanao, Philippines. NEIC reported it was felt with maximum intensity VI in Digos, V in Southern Mindanao in Biao, Kidapawan, Bulatukan, IV in Buayan, Bato, Ula and II-III in Davao and Koronadal. This may be a regional aftershocks of the M 5.4 about 150 km northeast of this on August 2, 2022 and the M 5.8 about 250 km west of today's epicenter on August 13. Forecast 145488 expected today's activity in mid-August.

The strongest earthquake in the U.S. or Canada today was an M 3.9 in the Fox Islands, Aleutians, Alaska. It was not reported felt in this remote area. This appears to be an aftershock of the M 4.6 in the Fox Islands which occurred August 13. That event was noted in this summary at the time as:

 

 

"The strongest earthquake in the U.S. or Canada today was an M 4.6 in the Fox Islands, Aleutians, Alaska. It was not reported felt in this remote area. An M 4.9 hit this area on August 1, 2022. These are probably aftershocks of an M 6.8 within about 25 km of today's epicenter which occurred on January 11, 2022.  Forecast 145904 had expected today's seismic enhancement was likely around August 13."

Light earthquakes continued today in the unusual swarm east of Bar Harbor, Maine. This series began on August 11, 2022 and was noted in this summary as:

 

"A series of light earthquakes occurred today east of Bar Harbor, Maine with M 3.1, 2.8 and 2.2.  Two earthquakes of M 2.8 and M 3.1 hit southeastern Maine today. NEIC reported they were felt with intensity II-III in Jonesboro, Columbia Falls, Machis and Addison. The M 3.1 is the strongest earthquake within about 100 km of this epicenter since an M 3.3 on February 2, 2016 and an aftershock to the north on February 9, 2016. This activity was probably promoted by high tides with today's full moon. Forecasts 145628 and 145871 had expected his activity within about 50 km of these epicenters was likely between August 5 and 13." (August 12, 2022)

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 7.0 in Luzon, Philippines July 27, 2022,  where promoted seismicity is considered likely.

 

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 SEISMICITY EXPANDS IN SOUTHWESTERN PACIFIC

 

EARTHQUAKE SUMMARY FOR AUGUST 14, 2022

 

Strong earthquakes continued near the geomagnetic equator in the southwestern Pacific Ocean area today. This included an M 6.4-6.6 in the southern Kermadec Islands of New Zealand and an M 6.4 in the Loyalty Islands/New Caledonia area south of Vanuatu. This had been expected in the previous issue of this summary as:

 

"Following strong geomagnetic storms, in the several days after they settle down, ring currents set up at about 10 degrees either side of the geomagnetic equator. These ring currents induce telluric electric currents in the earth below them. These, in turn, change the electrical environment in these areas and help to enhance seismicity in these areas. Global seismicity today showed this pattern. A series of moderately large to large earthquakes today occurred near 10 degrees from the geomagnetic equator. These events of M 5.7-5.9 are of a magnitude, location and timing suggesting they were promoted by this induction effect. They occurred as an M 5.9 in Papua New Guinea; an M 5.7 in the Molucca Sea of Indonesia and an M 5.8 and 5.9 in central Vanuatu. Triggering of this type is expected to continue for another day with strong earthquakes possible, especially in the southwest Pacific during the next several days." (August 14, 2022)

 

The strongest earthquake in the world today was an M 6.4-6.6 in the Kermadec Islands, New Zealand. It may have been felt lightly as far as North Island, New Zealand. This is the second strongest earthquake in the world in the past month following an M 7.0 in Luzon, Philippines on July 27. An M 6.6-6.8 also occurred in the Easter Island region on July 12, 2022 and an M 7.2 hit southern Peru on May 26, 2022, the last such events in the past three months. Today's event of M 6.6 is the strongest earthquake within about 200 km of this epicenter in the southern Kermadec Islands since an M 7.4 on June 18, 2020 and an M 6.9 on September 10, 2018 and an M 6.8 on December 9, 2008.

 

Forecasts 145716 and 145967 had expected this activity within about 25 km  was likely around August 9-14.

A strong earthquake of M 6.1 also occurred today in the area of the Loyalty Islands. NEIC reported it was felt in New Caledonia at Noumea Sud. The last earthquake in the world of M>=6.2 occurred on July 27, 2022 with M 6.2 on July 27, 2022 in Argentina and an M 7.0 on July 27, 2022 in Luzon, Philippines. The only other event of M>=6.2 in the world in the past month was an M 6.4 in the West Chile Rise on July 15, 2022. The last earthquake in the Loyalty Islands of M>=6.2 was an M 6.4 on May 26, 2022. Major event of M 6.9 and 7.0 occurred in this area on March 30 and 31, 2022 and these may be aftershocks of those event.  Forecast 145951 had expected today's activity was likely within about 100 km of this around August 14-18.

An unusual earthquake of M 4.1-4.8 occurred west of Portugal and the Strait of Gibraltar today. NEIC reported it was felt lightly in Portugal in Algarve at Lagos, Aloufeira, Portimac, Almandi and in Pombal, Centro Portugal. The last earthquake of M>=4.7 within about 250 km of this epicenter was an  M 4.8 on December 16, 2013 and an M 4.7 on April 22, 2010. The last of significantly larger magnitude was an M 5.5 on December 17, 2009. The largest earthquake in the area  in the past 30 years was an M 5.9-6.0 on February 12, 2007. This epicenter is near the antipode of the M 6.6 in the Kermadec Islands which occurred earlier in the day and may have been promoted by focused energy at the antipode of that earthquake. Forecast 145824 had expected today's earthquake in this area was likely around August 15.

The strongest earthquake in the U.S. or Canada today was an M 5.2. It was not reported felt in this remote epicentral area. This is the strongest earthquake in the Rat Islands since an M 6.3 near this epicenter on June 4 and is probably an aftershock of that event. Forecast 145910 had expected a moderate quake in the Rat Islands within about 100 km  of this epicenter was likely around August 14-18.

A moderate earthquake of M 5.3 was recorded south of Africa today. This event is near the antipode of recent activity in the Alaska Peninsula and may promoted enhanced seismicity in that region. Forecast 145974 had expected increased seismicity in this region south of Africa was likely around August 13.

A moderately strong earthquake was also recorded in southern Qinghai, China today with M 5.5. It was not initially reported felt but was likely damaging in the epicentral area. Reports from this area of China are often delayed by several days, so check later for damage reports. The epicenter is in  a lightly populated plateau and there were no local reports of damage from this earthquake. This is the strongest earthquake within about 200 km of this epicenter since an M 5.7 on March 19, 2021 and an M 5.9 on October 17, 2016. No events of M>5.9 have been recorded in the area in the past 30 years.  Forecast 145858 had expected regional seismic enhancement north of this epicenter in mid-August.

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.

ENHANCED SEISMICITY AT 10 DEGREES FROM GEOMAGNETIC EQUATOR

 

EARTHQUAKE SUMMARY FOR AUGUST 13, 2022

 

Following strong geomagnetic storms, in the several days after they settle down, ring currents set up at about 10 degrees either side of the geomagnetic equator. These ring currents induce telluric electric currents in the earth below them. These, in turn, change the electrical environment in these areas and help to enhance seismicity in these areas. Global seismicity today showed this pattern. A series of moderately large to large earthquakes today occurred near 10 degrees from the geomagnetic equator. These events of M 5.7-5.9 are of a magnitude, location and timing suggesting they were promoted by this induction effect. They occurred as an M 5.9 in Papua New Guinea; an M 5.7 in the Molucca Sea of Indonesia and an M 5.8 and 5.9 in central Vanuatu. Triggering of this type is expected to continue for another day with strong earthquakes possible, especially in the southwest Pacific during the next several days.

 

 

The strongest earthquake in the world today was an M 5.9 in Papua New Guinea. NEIC reported it was felt with intensity IV in PNG at Lae, Morobe, Kainantu, Eastern Highlands and II-III in Madang and Port Moresby. This event occurred near local solar midnight near the geomagnetic equator and was probably promoted by stresses associated with the Full moon of August 12 and the current geomagnetic storm. This is the strongest earthquake in eastern New Guinea within about 200 km of this epicenter since an M 6.0 on February 13, 2021 and an M 6.3 on October 8, 2020.  Forecast 145748 had expected seismic enhancement in this area was likely around August 12.

An earthquake of M 5.7 was also felt near the geomagnetic equator today in the area of the Molucca Sea, Indonesia. NEIC reported it was felt with intensity II in Bitung, Sulawesi. The Molucca Sea is highly seismic. The last event in the area within about 150 km of this epicenter with M>=5.7 occurred on April 5, 2022 with M 5.9.   Forecasts 145485 and 145731 had expected today's event within this area was likely around August 10-14.

Earthquakes of M 5.9 and M 5.8 also were felt in central Vanuatu today. NEIC reported it was felt with intensity V in Luganville, Sanma, and Vila Shefa, Vanuatu. This earthquake  of M 5.8 occurred within minutes of local solar midnight near the geomagnetic equator and was probably promoted by stresses associated with the full moon and the current geomagnetic storm. The last earthquake with M>=5.9 in Central Vanuatu within about 200 km of this epicenter occurred on April 9, 2022 with M 6.3 but more recent earthquakes in the area occurred with M 5.8 on April 17 and July 14, 2022. Forecast 145947 had expected this activity within about 100 km was likely around August 16-18.

An M 4.9-5.0 shook regions of western Turkey today. NEIC reported it was felt with maximum intensity IV in Aydin and Izmir, Turkey at Kusadasi, Selcuk, Soke, Seferihisar and II-III in Menderes, and in Samos, Greeece at Vathi, Kokkarion and Pithagorio. This is the strongest earthquake in this area within about 200 km of this epicenter since an M 5.1 on November 30, 2021 and an M 5.7 on August 1, 2021. These may be aftershocks of an M 7.0 which hit the area on October 30, 2020. At the time this summary noted in this regard:

 

 

 

"A major earthquake occurred in the Dodecanese Islands of Greece west of Turkey today with M 7.0 A moderate tsunami was reportedly slammed into coastal areas of Turkey and islands of Greece according to local news sources. The tsunami deluged the city of Izmir, Turkey with surging seawater which inundated the city with debris and caused a major recession of the water revealing ocean bottom. Other areas visited by the tsunami included the Greek islands of Ikaria, Kos, Samos and Seferihisar. Tsunami warnings were issued for the area. At least 20 buildings collapsed in Izmit, Turkey and the Dodecanese Islands and 20 were initially reported killed by the quake and one was drowned by the tsunami, but these tolls are expected to rise. Among the destroyed buildings was the Church of the Virgin Mary in Karlovasi. Two others were killed on Samos Island, Greece. At least 790 people were reported injured in the quake and tsunami. The tsunami caused many to flee inland. Relief operations are in effect by a series of Mediterranean countries including Israel, Azerbaijan, France, Turkey and Greece, NATO and the European Union. This is the first earthquake in the region of Greece which caused such extensive damage and deaths since an M 6.6 in the Aegean Sea in July 21, 2017. This follows an electric shock from the sun several hours earlier. It also coincides with planetary alignments with the sun, earth and Uranus and with Mars, Earth and Venus which are perpendicular to each other. But the main tidal stresses leading to the promotion of this earthquake are probably those associated with the full moon which arrives today as noted in previous issues of this summary as:

 

"The full moon will arrive on October 31 at 14:49 UT. Longitudes which are sub-solar at this time are near 40 West and 140 East. These include the central Atlantic in the west and Japan and much of the eastern Pacific Rim from Kamchatka to New Guinea in the east. These areas may see moderate seismic enhancement over the next seven days to enhanced tidal stresses but other tidally stressed areas may also see increased seismicity at this time."  (October 30, 2020)

 

The mainshock in Greece occurred within about an hour of local solar noon, a time when tidal stresses are maximized.

 

and with the continuing geomagnetic storm as:

 

"This is the strongest disturbance in the  geomagnetic field since September 28.  Strong disturbances in the geomagnetic field can help promote seismicity and may do so at high and low latitudes with this storm." (October 25-29, 2020, October 31, 2020)

 

Note that this earthquake in October, 2020 was also associated with a strong geomagnetic storm and the full moon.

 

Forecasts 145801 and 145853 had expected today's activity was likely within about 100 km around August 14-15.

The strongest earthquake in the U.S. or Canada today was an M 4.6 in the Fox Islands,  Aleutians, Alaska. It was not reported felt in this remote area. An M 4.9 hit this area on August 1, 2022. These are probably aftershocks of an M 6.8 within about 25 km of today's epicenter which occurred on January 11, 2022.  Forecast 145904 had expected today's seismic enhancement was likely around August 13.

The last earthquake in Alabama within about 100 km of this epicenter was an M 2.2 on December 11, 2021 and an M 2.6 on November 1, 2020. But today's event at M 2.7 is the strongest in this area since an M 3.1 on May 10, 2020.  Forecast 145849 had expected today's activity in this region was likely around August 14.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

MODERATE EARTHQUAKE SHAKES LIBYA AND EGYPT

 

EARTHQUAKE SUMMARY FOR AUGUST 12, 2022

 

An unusual earthquake of M 5.3 ocurred in Libya today.  NEIC reported this earthquake of M 5.2-5.3 in Libya was felt with intensity II-III in the area(s) of Libya in Bednghazi and al-Marj and possible in Egypt.  This is the strongest earthquake within about 300 km of this epicenter in Libya in at least 30 years. Recent earthquakes within about 200 km to the north in the region of Crete, Cyprus, Greece and the Mediterranean Sea have most recently occurred on May 20, 2020 (M 5.7) and in February, 2008. These occurred about 300 km northeast of today's epicenter. Forecast 145817 had expected today's activity in the region of Crete, Greece was likely around August 12.

The strongest earthquake in the world today was an M 5.8 in the Moro Gulf, Mindanao, Philippines.  NEIC reported maximum intensity VI in Dalumangoob, Muslim, Mindanao and V in Mindanao at Limulan, Labunga, Sinolon and Gandiangan with lesser shaking in Mindanao at Cotqabato, Koronadal, Ozamiz, Mahayag and Buayan. This is the strongest earthquake in the Moro Gulf, Mindanao since an M 6.4 on August 1, 2020 but unlike that event at a deep focus, today's was at a shallow focus of 16 km depth. Forecast 145488 had expected today's event was likely within about 100 km of this epicenter was likely around August 10.

The earthquake in Mindanao was preceded two hours earlier by an M 5.1

in Panay, Philippines.  NEIC reported this earthquake of M 5.1 in Panay, Philippines was felt with intensity II-III in the area(s) of Panay, Philippines in San Jose, San Miguel Iloilo, Western Visayas. These events occurred near local solar noon and were probably promoted by strong tidal stresses with the new moon. Forecast 145771 had expected today's event within about 100 km was likely around August 17.

An earthquake of M 4.6 occurred today south of Tokyo, Japan. This event occurred as Tropical Storm Meari passed through the area. It is likely that this event was promoted by stresses associated with this storm. This had been expected in this summary as:

 

"Tropical Storm Meari (09W) continued in the North Pacific Ocean south of Honshu, Japan today with winds up to 45 kts. It is expected to track to the north and east passing over southeastern Honshu in the next several days. Enhanced seismicity is likely in this region while this storm passes through the region."

The swarm of earthquakes east of Bar Harbor, Maine continued today. This is an

unusual swarm which was noted in the previous issue of this summary as:

 

 

"A series of light earthquakes occurred today east of Bar Harbor, Maine with M 3.1, 2.8 and 2.2.  Two earthquakes of M 2.8 and M 3.1 hit southeastern Maine today. NEIC reported they were felt with intensity II-III in Jonesboro, Columbia Falls, Machias and Addison. The M 3.1 is the strongest earthquake within about 100 km of this epicenter since an M 3.3 on February 2, 2016 and an aftershock to the north on February 9, 2016. This activity was probably promoted by high tides with today's full moon. Forecasts 145628 and 145871 had expected his activity within about 50 km of these epicenters was likely between August 5 and 13." (August 12, 2022)

The strongest earthquakes in the U.S. or Canada today occurred off the coast of

Oregon with an M 3.9 far off the coast and an M 3.9 nearer to the coast.  These events occurred near local solar midnight and local solar noon and were probably promoted by high tidal stresses with the new moon of August 12 which maximized near these hours. Forecasts 145885 and 145884 had expected this activity within about 50 km was likely in mid-August.

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 7.0 in Luzon, Philippines July 27, 2022,  where promoted seismicity is considered likely.

 

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 EXPECTED SEISMIC ENHANCEMENT

 

EARTHQUAKE SUMMARY FOR AUGUST 11, 2022

 

The full moon today was accompanied by an M 5.4 in the South Sandwich Islands and an M 4.2-4.6 in western Texas. Both these areas have shown consistent triggering of seismicity at times of lunar-solar tidal alignments at full and new moon - activity which is likely related to these high earth tides as detailed in many previous issues of this summary.

 

The strongest earthquake in the world today was an M 5.4 in the South Sandwich Islands. This was not reported felt in this remote area. This is the strongest

earthquake in the South Sandwich Islands since a similar M 5.4 on June 29, 2022. That event also occurred with high tides related to the new moon of that date. Today's event occurred within several hours of the full moon alignment as noted in this and previous issues of this summary as:

 

"The full moon will arrive at 01:36 UT on August 12, 2022. Longitudes which are anti-solar at this time are near 20 West and those at sub-solar (local solar noon) are near 160 East longitude. These include Iceland and areas of the mid-Atlantic and western Europe in the west and Kamchatka, Kurils, Vanuatu and areas of the southwestern Pacific. These areas are most likely to see tidal triggering during the next week including the possibility of a strong associated earthquake at high latitudes and/or near the geomagnetic equator. These are most likely near local solar noon or midnight but tidal triggering is diffuse and can affect seismicity throughout many portions of the world." (August 9-12, 2022)

 

Forecast 145977 had expected today's event within about 100 km was likely around August 13.

The strongest earthquake in the U.S. or Canada today was an M 4.2-4.6 in Western Texas. This event occurred within minutes of local solar midnight in an area which often triggers with new and full moon alignments. The strongest earthquake in the area in recent years was an M 5.0 on March 26, 2020 - associated with the new moon of March 24, 2020. The only other event in this region in the past 30 years of larger magnitude then M 4.5-4.6 occurred on July 21, 2022 with M 4.9. An earthquake of M 5.0 also hit the area on January 2, 1992. Events of M 4.6 and 4.3 also hit the area on June 1, 2022 with the new moon of May 30, 2022. Forecast 145836 had expected today's activity was likely around August 13 within about 50 km of today's epicenter. On July 22, 2022 this summary noted:

 

"The most active area of the U.S. or Canada today was Western Texas. This is an active area and often shows tidally promoted seismicity. A series of three earthquake of M 3.0 hit the area today near local solar midnight. Earthquakes of this size in this region are common. The last of M>=3 in the region was an M 3.4 on July 16, 2022." (July 20-21, 2022)

 

An earthquake of M 4.6 hit this region of western Texas on March 25, 2022, the strongest previously in the past two years. The last earthquake in Texas of equal or larger magnitude than M 4.7 was recorded by NEIC on March  26, 2020 but the only event of significantly larger magnitude in Texas in the past 30 years was an M 5.7 on April 14, 1995 about 150 km southeast of today's epicenter." (July 22, 2022)

 

NEIC reported the mainshock was felt with intensity IV in Pecos, Texas and II-III in New Mexico in Carlsbad, Roswell, Alamogordo and Ruidoso.

A series of light earthquakes occurred today east of Bar Harbor, Maine with M 3.1, 2.8 and 2.2.  Two earthquakes of M 2.8 and M 3.1 hit southeastern Maine today. NEIC reported they were felt with intensity II-III in Jonesboro, Columbia Falls, Machias and Addison. The M 3.1 is the strongest earthquake within about 100 km of this epicenter since an M 3.3 on February 2, 2016 and an aftershock to the north on February 9, 2016. This activity was probably promoted by high tides with today's full moon. Forecasts 145628 and 145871 had expected his activity within about 50 km of these epicenters was likely between August 5 and 13.

An M 3.5 also occurred north of the Bar Harbor, Maine epicenter several hours earlier. Earthquakes Canada reported it was lightly felt in this epicentral area. The only event within about 100 km of this epicenter with M>=3.5 in the past 30 years was an M 4.2 on November 27, 2012. Forecast 145628 had expected this activity within about 50 km was likely around August 9.

 

NEIC reported this earthquake of M 3.5 in Quebec, Canada was felt with intensity II-III in the area(s) of  Hauterive, Quebec.

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 SWARM IN HOKKAIDO, JAPAN

 

EARTHQUAKE SUMMARY FOR AUGUST 10, 2022

 

The strongest seismicity in the world today was a series of moderate quakes in the Hokkaido region of northern Japan. They were lightly felt in Hokkaido and Aomori Prefectures. The strongest of these - an M 5.1 was preceded 17 minutes earlier by an M 4.8 foreshock. These events occurred near local solar midnight and may have been promoted by geomagnetic or tidal effects which maximize near this hour. The latest earthquake within about 200 km of this epicenter with M>=5.1 occurred as an M 5.9 at intermediate focus on July 2, 2022 but this event  Forecast 145623 had expected this activity was likely within about 200 km in early August.

An earthquake of M 5.1 also continued the series of moderate to large earthquakes in the South Sandwich Islands region today. This is a bit removed from the typical aftershock zone being about 150 km northeast of the most recent moderate quakes in the area. The last earthquake in the area within about 150 km of this epicenter with M>=5.1 occurred as an M 5.3 on May 19, 2022.   Forecast 145723 had expected today's event within about 25 km was likely around August 6.

An unusual earthquake of M 2.7 also occurred today in Southern Idaho. NEIC reported this earthquake of M 2.7 in Wyoming was felt with intensity II-III in the area(s) of Wyoming in Alta, Wilson and in Idaho at Driggs, Tetonia. This is the strongest earthquake within about 100 km of this epicenter since an M >=2.7 was an M 3.1 on December 30, 2019.  Forecast 145652 had expected this event within about 50 km was likely around August 10.

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 7.0 in Luzon, Philippines July 27, 2022,  where promoted seismicity is considered likely.

 

 

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.

HIGH LATITUDE AND GEOMAGNETIC EQUATOR SEISMICITY WITH GEOMAGNETIC STORM

 

 

EARTHQUAKE SUMMARY FOR AUGUST 9, 2022

 

Moderate earthquakes continued on the geomagnetic equator today with continuing geomagnetic storms as noted in this summary:

 

"The geomagnetic field saw storm conditions today. The AP level was 19. High latitudes also  saw  major storm conditions with AP 45. This should break the current lull in global seismicity and bring about more active conditions at high latitudes and near the geomagnetic equator over the next several days. This is the strongest geomagnetic storm in the past four months - since AP reached 38  on April 14, 2022 with high latitude AP 56 on that date. If a major flare occurs, a strong to major earthquake is possible at this time." (August 9, 2022)

 

 

The strongest earthquake felt in the world today was an M 5.6 in the Banda Sea, Indonesia. It may have been felt lightly in the Northern Territory of Australia. NEIC reported this earthquake was felt with intensity II-III in the area(s) of  Coonawarra, Darwin and Howard Springs.  This epicenter is located near the geomagnetic equator and was probably promoted by geomagnetic effects from the geomagnetic storm which was near maximum at the time of this earthquake. Forecast 145510 had expected today's event within about 25 km was likely around August 6.

An M 5.7 in Aisen, Chile was not reported felt. This is the largest aftershock to date of the M 6.4 in Aisen, Chile of July 15. That event occurred about 50 km east of today's epicenter. Today's event at high latitude was probably  promoted by the current geomagnetic storm which was at maximum near the time of this earthquake. This activity as well as an M 5.1 in the West Chile Rise to the west of this epicenter is located at 144 degrees from the M 7.0 in Luzon, Philippines of July 27 and was probably promoted by energy from that source.

Enhanced seismicity continued in the western U.S. and Canada today with the continuing geomagnetic storm. While light aftershocks continued in central California and in the Vancouver region of British Columbia, the strongest earthquake in the U.S. or Canada was an M 4.6 in the central Fox Islands, Aleutians, Alaska. This earthquake is the strongest within about 150 km of this epicenter since an M 5.2 about 100 km east of this on June 2, 2022 and an M 4.8 on January 11, 2022. Forecast 145658 had expected activity within about 50 km of this epicenter was likely in early August.

An M 4.3 was also recorded today off the coast of Northern California and Oregon. NEIC reported this earthquake of M 4.3 off the coast of Oregon  was felt with intensity II-III in the area(s) of  Oregon in Brookings. An M 5.9 hit this region on June 4, 2021 about 100 km north of today's epicenter. This may be the strongest regional aftershock to date of that event. Forecast 145640 had expected today's event within about 25 km was likely around August 6.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

WESTERN NORTH AMERICA SHAKES AMIDST GEOMAGNETIC STORM

 

EARTHQUAKE SUMMARY FOR AUGUST 8, 2022

 

The geomagnetic storm which began August 7, 2022 continued unabated today. It has been noted in this summary as:

 

"The geomagnetic field saw minor storm conditions today. The AP level was 24. High latitudes also  saw minor to major storm conditions with AP 42. This should break the current lull in global seismicity and bring about more active conditions at high latitudes and near the geomagnetic equator over the next several days. If a major flare occurs, a strong to major earthquake is possible at this time." (August 7-8, 2022)

 

and

 

"The geomagnetic field saw storm conditions today. The AP level was 31. High latitudes also  saw  major storm conditions with AP 48. This should break the current lull in global seismicity and bring about more active conditions at high latitudes and near the geomagnetic equator over the next several days. This is the strongest geomagnetic storm in the past four months - since AP reached 38  on April 14, 2022 with high latitude AP 56 on that date. If a major flare occurs, a strong to major earthquake is possible at this time." (August 8, 2022)

 

Today's storm was accompanied by a pair of unusual moderate earthquakes in western U.S. and Canada - of M 4.6-4.7 in the Vancouver Island, BC area of Canada and on the California-Nevada border region.

 

 

The M 4.6-4.7 in the Vancouver Island area was followed by a series of light aftershocks. It was probably felt lightly in the epicentral area but this has not been reported at this time. It occurred within half an hour of local solar midnight and was probably promoted by tidal/geomagnetic effects which maximize near this hour. This is the strongest earthquake in the Vancouver Island area within about 150 km of this epicenter near Port Alice, BC since an M 5.4 on July 22, 2020. Continuing activity about 200 km to the northwest of this saw events of M 4.6 on June 13, 2022 and April 23, 2022.  Forecast 145650 had expected today's activity was likely within about 50 km around August 7.

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. This activity occurred at 101 degrees from the M 7.0 in Luzon, Philippines of July 27 and may have been promoted by energy from that source.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

GEOMAGNETIC STORM BRINGS RENEWED SEISMICITY TO HIGH LATITUDES

 

EARTHQUAKE SUMMARY FOR AUGUST 7, 2022

 

A moderately strong geomagnetic storm occurred today as noted in this summary:

 

"The geomagnetic field saw minor storm conditions today. The AP level was 24. High latitudes also  saw minor to major storm conditions with AP 42. This should break the current lull in global seismicity and bring about more active conditions at high latitudes and near the geomagnetic equator over the next several days. If a major flare occurs, a strong to major earthquake is possible at this time." (August 7-8, 2022)

 

This storm was accompanied by an increase in seismicity at high latitudes and near the geomagnetic equator as expected.  The strongest earthquake in the world today was an M 5.8-5.9 east of the Kuril Islands. NEIC reported this earthquake of M 5.8 was felt with intensity IV in the area(s) of  Kurilsk, Russia.  This is the strongest earthquake in the world since events of M 6.2 and 6.1 in northern Chile on July 27 and 28, 2022 and the M 7.0 in Luzon, Philippines on July 27, 2022, both of which were probably promoted by strong tidal stresses with the new moon of that date.  The M 5.8-5.9 in the Kuril Islands was the strongest within about 200 km of that epicenter since an M 7.0 north of this on February 13, 2020 and prior to that an M 5.9 on November 28, 2015. A slightly smaller event hit near this epicenter with M 5.7-5.8 on March 2, 2021. Forecast 145624 had expected this event was likely around August 5. Like much of today's enhanced seismicity, this event occurred near the height of today's geomagnetic storm near local solar midnight and was probably promoted by tidal and geomagnetic effects.

An earthquake of M 5.6 also occurred today in New Britain, PNG.  NEIC reported this earthquake of M 5.6 in New Britain, PNG was felt with intensity II-III in the area(s) of New Britain, PNG in Rabaul. This epicenter is near the geomagnetic equator and was probably promoted by energy from the geomagnetic storm. It is the strongest earthquake within about 150 km of this epicenter since an M 6.1 on April 13, 2022 and an M 5.7 on December 9 and June 8, 2021.  Forecast 145499 had expected today's event to the south in New Ireland was likely around August 7.

The strongest earthquake in the U.S. or Canada today occurred in the Unalaska, Aleutians, Alaska area. NEIC reported this earthquake of M 4.6 in Alaska was felt with intensity II-III in the area(s) of Alaska at Unalaska.  This is the strongest earthquake within about 150 km of this epicenter since an M 5.3 on August 1, 2022 and an M 5.2 on June 8, 2022 after half a year of quiet in the area.  It occurred at the maximum of today's geomagnetic storm when Kp was 6 and was probably promoted by that storm.  Forecast 145661 had expected today's event within about 10 km of this epicenter was likely around August 7.

A moderate M 3.9 quake occurred today in western Texas and was followed by a series of light aftershocks. It occurred near local solar midnight during the height of the geomagnetic storm today and was probably promoted by tidal and geomagnetic effects. Forecast 145594 had expected this activity was likely around August 8.

 

NEIC reported this earthquake of M 3.9 in Western Texas was felt with intensity II-III in the area(s) of Western Texas in Pecos.

Another earthquake that occurred near the height of the geomagnetic storm was an M 4.8 in the Southern Mid-Atlantic Ridge. This event occurred near local solar noon near the geomagnetic equator. Similar events hit within about 200 km of this epicenter on February 10, 2022 and June 25, 2021. Forecast 145458 had expected this event was likely within about 100 km at the end of July or in early August.

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 7.0 in Luzon, Philippines July 27, 2022,  where promoted seismicity is considered likely.

 

 

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.

LIGHT TO MODERATE QUAKES SHAKE SOUTHERN PUERTO RICO

 

EARTHQUAKE SUMMARY FOR AUGUST 6, 2022

 

A series of light to moderate earthquakes shook the region of southern Puerto Rico today. NEIC reported these earthquakes of M 4.2, 4.7 ... in Puerto Rico were felt with intensity II-III in the area(s) of Puerto Rico  at Ensenada (IV), Guayanilla, Yauco, San German, Ponce, Cabo Rojo, Ponce. This area is at 144 degrees from the M 7.0 in the northern Philippines Luzon Island of July 27. In addition to moderately large quakes in Honduras and Nicaragua in the past several days at this distance from Luzon, several preliminary swarms since then have suggested the possibility of enhanced seismicity in this region at this time as noted in previous issues of this summary:

 

 

"A sequence of light earthquakes also occurred today in eastern Puerto Rico. This area often shows strong seismic enhancement early in August, probably related to renewed strong weather events in the area. For example, in 1946 an M 8.1 hit this region (see History section of this summary). This area often sees this activity in early August and in December-January. These epicenters are at 144 degrees from the M 7.0 in Luzon, Philippines of July 27 and may have been promoted by seismic energy from that source. Further and larger events are expected in this region in the next  several days. Forecast 135523 and 145523 had expected this activity in Puerto Rico in early August." (August 4, 2022)

 

Today's series appears to be an aftershock group of the M 6.4 in southwestern Puerto of January 7, 2020. The last aftershock of this event with M>=4.5 occurred more than a year ago as an M 4.5 on July 18, 2021. The last of larger magnitude was an M 4.7 and 4.8 on December 24, 2020.  Forecast 145533 had expected this activity within about 25 km was likely around August 4.

The only earthquakes in the world today to exceed M 5.0 was an M 5.1 in Tarapaca Northern Chile and a second near the east coast of Honshu, Japan north of Tokyo where it was lightly felt. This continues the quiet period of seismicity in the world noted in the previous issue of this summary as:

 

 

"It was a relatively quiet day in global seismicity. The strongest earthquake in the world barely exceeded M 5.0 and regional seismicity was also muted. The absence of major ocean storms, geomagnetic storms and strong tides associated with  lunar-solar alignments is likely one of the contributing factors related to this quiet period. A solar storm and geomagnetic storm is expected around August 7-8 which could bring enhanced seismicity at that time." (August 6, 2022)

 

NEIC reported this earthquake of M 5.0 near the coast of Honshu, Japan  was felt with intensity II-III in the area(s) of Honshu, Japan in Ibaraki and Chiba Prefectures.  Forecast 145590 had expected today's event in Honshu  was likely within about 100 km around August 4.

The strongest earthquake in the U.S. or Canada today was an M 4.2 south of Alaska. It was not reported felt. This is a somewhat unusual epicenter. The last event of M>=4.2 within about 150 km of this occurred as an M 4.7 a year ago on July 30, 2021.  Forecast 145654 had expected today's event to the southwest was likely around August 7.

Light earthquakes also occurred today in Eastern Tennessee (M 2.0) and in New Hampshire (M 2.3). The activity in Tennessee occurred within minutes of local solar noon in an area where torrential floods have recently occurred. It is likely it was promoted by loading from these floods as well as by tidal stresses. Forecast 145578 had expected this event within about 50 km was likely around August 6.

Only one event of M>2.3 has occurred in New Hampshire in the past two years - and M 2.9 about 150 km northeast of today's epicenter on February 4, 2022.  An M 2.2-2.3 also occurred on January 15, 2022. Forecast 145634 had expected today's event in New Hampshire was likely in this region around August 8.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

QUIET DAY IN GLOBAL SEISMICITY

 

EARTHQUAKE SUMMARY FOR AUGUST 5, 2022

 

It was a relatively quiet day in global seismicity. The strongest earthquake in the world barely exceeded M 5.0 and regional seismicity was also muted. The absence of major ocean storms, geomagnetic storms and strong tides associated with  lunar-solar alignments is likely one of the contributing factors related to this quiet period. A solar storm and geomagnetic storm is expected around August 7-8 which could bring enhanced seismicity at that time.

 

The strongest earthquakes in the world today were of M 5.0 - in the ongoing series in the Izu Islands south of Honshu, Japan and in the South Sandwich Islands. Both areas have been active at higher levels in recent days and these events were not reported felt in these remote regions.

 

Forecast 145589 had expected the activity in the Izu Islands around August 7 within about 100 km of these epicenters.

The strongest earthquake in the U.S. or Canada today was an M 3.6 in Southern  Alaska. This is an active area with 12 events of similar or greater magnitude in the area during the past six month. The last was an M 4.7 on July 12, 2022. The largest was an M 5.1 on March 12, 2022 and on January 21, 2022.  NEIC reported this earthquake of M 3.4 in Southern Alaska was felt with intensity II-III in the area(s) of Southern Alaska in Anchorage and Chugiak.  Forecast 145675 had expected enhanced seismicity in this area was likely around August 6.

Today's earthquake and forecast map follows. Stippled White areas are nodal distances (360/n, n an integer) from the earthquake of M 7.0 in Luzon, Philippines July 27, 2022,  where promoted seismicity is considered likely.

 

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.
