MODERATE QUAKE IN SULAWESI, INDONESIA

EARTHQUAKE SUMMARY FOR AUGUST 18, 2022

It was a relatively quiet day in global seismicity. This is consistent with a slowdown in seismicity during strong geomagnetic storms. Geomagnetic storms disrupt the ionospheric ring currents and subsequent induction of telluric currents and possibly seismicity beneath these electric currents. Normal to strong enhancement in global seismicity can occur during this time if the earthquake is hit by a powerful shock wave of solar wind emanating from a strong solar flare. However in the current case, this has not occurred. Once the ring currents regenerate at higher intensities, they can trigger additional seismicity normally about 2-4 days after the end of the geomagnetic storm. In the current situation this storm is expected to end around August 20-21.

The strongest earthquake in the world today was an M 5.4 in Sulawesi, Indonesia was felt with intensity II-III in the area(s) of Sulawesi, Indonesia in Bitung.

NEIC reported this earthquake of M 5.4 in Sulawesi, Indonesia was felt with intensity II-III in the area(s) of Sulawesi, Indonesia in Bitung. Enhanced seismicity in this region was discussed in relation to the current geomagnetic storm in the previous issue of this summary as:

"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, 18, 2022)

Today's event of M 5.4 is the strongest in Sulawesi, Indonesia and Minahasa since an M 5.6 on June 7, 2022 but the last of significantly larger magnitude in this area was an M 6.2-6.5 a year ago on July 26, 2021. Forecast 145732 had expected today's event within about 150 km was likely around August 16.

Two oceanic areas saw moderate seismicity today. An M 5.3 in the South Sandwich Islands continued the series in that region today. While earthquakes of M 5.3-5.4 hit this region on August 12 and June 29, 2022, the last event of significantly larger magnitude in the South Sandwich Islands was an M 5.5 on June 4, 2022. Forecast 145977 had expected today's event within about 100 km was likely around August 15.

A series of earthquakes also occurred in the Southern Atlantic region near the geomagnetic equator today. These events of M 5.1 appear to also have been promoted by tidal stresses as they occurred near local solar midnight and with the geomagnetic storm which maximized near the time of these events. In previous issues of this summary, the longitudes near these events in the Atlantic had been expected to see enhanced seismicity with the full moon of August 12, 2022 as:

"The full moon arrived at 01:36 UT on August 12, 2022. Longitudes which were 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." (June 10-17, 2022)

Forecast 145938 had expected enhanced seismicity to the north of this in the

Southern Mid-Atlantic Ridge was likely around August 20.

OTHER GLOBAL EARTHQUAKE ACTIVITY

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

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:

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.

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.

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." (August 13, 2022)

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)

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:

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.

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.
