MODERATE QUAKE SHAKES TAIWAN WITH NEW GEOMAGNETIC STORM; FULL MOON
EARTHQUAKE SUMMARY FOR NOVEMBER 25, 2023
A moderate earthquake of M 5.0-5.4 was felt in the area of Taiwan today in Taipei with intensity III. NEIC reported this earthquake of M 4.9 in the area of Taiwan was felt with intensity II-III in the area(s) of Taiwan with intensity IV in Yonakuni, Japan. EMSC reported moderate shaking in Taiwan in the Linkou District and in Taipei for this activity. CWB reported this earthquake with M 5.4 was felt with intensity II in Taiwan in Hualien, Taipei and Yilan Counties and I in Nantou, Taichung, Changhua, Taitung, Yunlin, Chiayi, Taoyuan, Hsinchu Counties. CWB reported intensity II in Hualien, Yilan, Taipei and I in Nantou, Taichung, Changhua, Taitung, Yunlin, Chiayi, Miaoli, Taoyuan, Hsinchu Counties, Taiwan. A foreshock of M 4.7 minutes before hit the same area and was reported by CWB to have been felt with intensity I in Hualien, Yilan and Taitung Counties. These events occurred within minutes of local solar noon and were probably promoted by strong tidal stresses with tomorrow's full moon which maximize near this time, as noted in this and previous issues of this summary:
"The full moon will arrive on November 27, 2023 at 09:16 UT. Longitudes at local solar noon were near 37 East while those at local solar midnight are near 143 West longitude. These include Hawaii and areas of eastern Alaska and western Canada and to a lesser extent areas off the coast of Oregon and California while in the east they include Eastern Turkey where an M 7.7 hit on February 6, 2023 as well as Ethiopia and areas off southern Africa. These and surrounding areas are the most likely to see tidally enhanced seismicity at this time. A moderate to large aftershock is possible in Turkey at this time." (November 23-26, 2023)
This event in Taiwan also continued regional enhancement which has included several strong earthquakes in the past week, the largest of which was the M 7.0 in the Mariana Islands of November 24. This summary has suggested this activity was related to the geomagnetic storm as:
"The geomagnetic field saw stormy conditions today. The AP level was 38. High latitudes saw major storm conditions with AP 61. Middle latitudes were at disturbed conditions with AP 18. This resumes a storm of November 22, 2023 which was the strongest ionospheric disturbance since AP reached 40 on November 6 and the most disturbed at high latitudes since high latitude AP reached 86 on October 28, 2023. This activity is likely to further enhance global seismicity near the geomagnetic equator and at high latitudes with the potential to trigger strong earthquakes in that zone in the next several days. A strong to major earthquake near the geomagnetic equator is likely in the next three days following this storm." (November 25-26, 2023)
A similar M 5.4 hit Taiwan on November 19 but the last of larger magnitude occurred a month ago with M 5.6-5.7 on October 23, 2023. At the time this summary noted:
"A moderately strong earthquake of M 5.9 was felt widely in the region of the Ryukyu Islands and Taiwan today. NEIC reported maximum intensity IV in Taiwan in Taipei with lesser shaking in Ilan, and Okinawa, Japan. CWB reported the M 5.7 was felt with intensity III in Hsinchu, Hualien, Yilan, Changhua, Yunlin; II in Nantou, Taichung, Kaohsiung, Taitung, Chiayi, Miaoli, Taoyuan, Tainan and I in Penghu and Pingtung Counties, Taiwan. A larger event of M 5.8 hit Taiwan near this epicenter on October 11 but the last event in southwestern Ryukyu Islands of greater magnitude occurred as an M 5.7 on October 16, 2023 which was probably an aftershock of an M 6.4-6.8 on September 18 a month earlier but also with the new moon." (October 23, 2023)
Forecasts 158322 and 158325 had expected today's activity in Taiwan was likely towards the end of November.

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

MAJOR EARTHQUAKE HITS NORTHERN MARIANA ISLANDS
EARTHQUAKE SUMMARY FOR NOVEMBER 24, 2023
The strongest earthquake in the world today was a major quake of M 6.9-7.0 in the northern Mariana Island in the Maug Islands Region where NEIC reported it was felt with intensity up to VI. This epicenter is near the geomagnetic equator and today's event may have been promoted by the end of the strong geomagnetic storm of the past several days as noted in the previous issue of this summary:
"The geomagnetic storm noted in previous issues of this summary has reduced to quiet levels today. A strong earthquake following this is likely near the geomagnetic equator in the next several days as noted in this summary:
"The geomagnetic field saw quiet conditions today. The AP level was 7. High latitudes saw quiet conditions with AP 8. Middle latitudes were at quiet conditions with AP 4. This concludes a storm which was the strongest ionospheric disturbance since AP reached 40 on November 6 and the most disturbed at high latitudes since high latitude AP reached 86 on October 28, 2023. This activity is likely to enhance global seismicity near the geomagnetic equator and at high latitudes with the potential to trigger strong earthquakes in that zone in the next several days. A strong to major earthquake near the geomagnetic equator is likely in the next three days following this storm." (November 22-24, 2023)
This event in the Mariana Islands was probably promoted by energy from solar
Flare 2190 which began at about the origin time of the mainshock in the Marianas. This was one of three M1 solar flares in the past two days, and the largest to occur today. Following is the date from SWPC for this flare:
Flare # START MAX END CLASS DATE Flux (Jm-2)

2190 0910 0933 0943 M1.1 (November 24, 2023) 1.1E-02
The last earthquake with M>=6.9 within about 200 km of today's event was an M 7.7 on July 29, 2016 and prior to that an M 7.2 on October 31, 2007. Today's event occurred at 16 km depth and is the strongest event within about 200 km at shallow focal depth in at least 35 years and no events of M>=6.9 have occurred within 125 km of today's epicenters in this time period.

A pair of moderate earthquakes occurred today in Alaska. This included an M 4.9 in the Fox Islands and an M 4.5 in the Gulf of Alaska. The M 4.9 in the Fox Islands is the largest event in this region within about 200 km since an M 5.6 on October 12, 2023. At the time this summary noted:
"The strongest earthquake in the U.S. or Canada today was an M 5.6 in the western Fox Islands, Aleutians, Alaska. NEIC reported it was felt with intensity IV in Atka, Alaska. The last earthquake within about 150 km of this epicenter with equal of larger magnitude occurred on September 27, 2020 and October 26, 2019 with M 5.6 and 5.9.
It is likely that this event was promoted by strong tidal stresses associated with upcoming new moon and eclipse which passes over this epicenter early on October 14. Further enhanced seismicity in the Aleutians is likely with the new moon and eclipse in the next several days. This could include a strong earthquake." (October 12, 2023)
Forecast 158442 had expected this event in the Fox Islands was likely within about 150 km around November 25.

The last earthquake in the Gulf of Alaska with M>=4.5 was an M 4.7 on November 17, 2023. At the time this summary reported in this regard:
"The strongest earthquake in the U.S. or Canada today was an M 4.7 in the Gulf of Alaska. It was not reported felt in this remote area. Earthquakes of M>=4.7 in the Gulf of Alaska in the past three years within about 200 km of today's epicenter occurred on October 24, 2020 (M 4.8) and February 3, 2022 (M 4.9). No earthquakes of M>=5 have occurred in this area since an M 5.1 on March 20, 2020. These appear to be aftershocks of the great quake of M 7.9 on January 23, 2018." (November 17, 2023)
This epicenter is at the sixth node (60 degrees) from the Mariana Islands M 6.9 today and was likely promoted by energy from that source.
Forecast 158197 had expected enhanced seismicity in this region was likely
around November 18.

A moderate earthquake of M 3.9 also occurred in Maui, Hawaii today. NEIC reported it was felt with intensity IV in Makena, Hawaii. The last earthquake of equal or greater magnitude in this area of Maui was an M 4.0 on December 16, 2022 but the last earthquake in this area of significantly larger magnitude was an M 4.7 on January 25, 2022. At that time this summary noted:
"The strongest earthquake felt in the U.S. or Canada today was an M 4.7 in the region of Maui, Hawaii. NEIC reported it was widely felt with maximum intensity IV in Haiku, Kana, Makawao, Kula and III in Kihei, Pala, Kahului, Waikuku, Lahaima, and Hawi. The last earthquake in the Maui area of Hawaii within about 100 km of this epicenter of larger magnitude occurred on July 5, 2021 with M 5.2 and prior to that an M 4.8 on November 24, 2010. The largest event in the past 30 years in the area was an M 6.1 on October 15, 2006. Two earthquakes of M 4.7 occurred in February and March, 2017 in the area." (January 25, 2022)
Today’s epicenter is at the exact same latitude as the M 7.0 in the Mariana Islands today (20.1 North) and occurred about an hour before that event. It is also located near the seventh node (52 degrees) from the Mariana epicenter. The exact relation between these events is not known at this time.
Forecast 158295 had had expected today's event within about 50 km was likely
around November 28.

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.

END OF GEOMAGNETIC STORM MAY BRING STRONG QUAKE; POSSIBLE ICELANDIC ERUPTION
EARTHQUAKE SUMMARY FOR NOVEMBER 23, 2023
The geomagnetic storm noted in previous issues of this summary has reduced to
quiet levels today. A strong earthquake following this is likely near the geomagnetic equator in the next several days as noted in this summary:
"The geomagnetic field saw quiet conditions today. The AP level was 7. High latitudes saw quiet conditions with AP 8. Middle latitudes were at quiet conditions with AP 4. This concludes a storm which was the strongest ionospheric disturbance since AP reached 40 on November 6 and the most disturbed at high latitudes since high latitude AP reached 86 on October 28, 2023. This activity is likely to enhance global seismicity near the geomagnetic equator and at high latitudes with the potential to trigger strong earthquakes in that zone in the next several days. A strong to major earthquake near the geomagnetic equator is likely in the next three days following this storm." (November 22-23, 2023)
The last such geomagnetic storm was followed by a series of escalating earthquakes in Iceland. This led to speculation that a possible volcanic eruption near Reykjavik could occur. While no such eruption has occurred yet, a series of hundreds of minor quakes today suggested that the current geomagnetic storm may trigger this expected eruption. At the time of the previous storm this summary noted in this regard:
"An imminent eruption is possible in the area near Reykjavik, Iceland. Earthquakes today included an M 5.0 and 5.1 in the region of Grindavik, Iceland. This town of about 3500 has been ordered evacuated due to the likelihood of this eruption. EMSC reported these events were felt with strong intensity in Mosfellsbaer, Kopavogur, Keflavik, Suournesjabaer, Seltjarnarnes, Reykjavik, among others. This continues the current series of eruptions which began in 2021 - part of a sequence that occurs with about 700 year intervals and can last as long as 100 years. In this area of Iceland this involves motions between the North American tectonic and the European tectonic plates. Initial lava flows can be up to 100 feet per minute – faster than walking pace. There area some infrastructure near the site of this imminent eruption include the town of Grindavik several km away and a power plant and roads which could be damaged in an eruption. Several roads were actually reported damaged near Grindavik today by earthquakes." (November 11, 2023)
The strongest earthquake in Iceland today was an M 2.8 that was not felt in the region. This event may have been promoted by Solar Flare 1920 which was near its height at the time of this event. Forecast 158462 had expected today's event was likely within about 25 km around November 23, 2023.

The strongest earthquake in the world today was an M 5.3 in the aftershock zone of the M 7.8 of February, 2023. NEIC reported this earthquake of M 5.3 in Turkey was felt with intensity up to VI in the area(s) of Turkey in Sincik. EMSC reported this event of M 5.3 and an aftershock of M 4.6 were strongly felt in Turkey at Malatya, Battalgazi, Seyh Bayram, Yesilyurt, Adiyaman, Camiisuk, Elazig, with moderate shaking in Karakopru, Sanliurfa, Elbistan and as far away from the epicenter as 400 km in Syria and Lebanon. These earthquakes occurred with an M1.0 solar flare (1960) and were possibly triggered by SFE associated with that event (see flare listing below). Two M-class flares were catalogued by SWPC today, including the strongest such flare - an M1.4 (# 1880) - since an M1.6 (#6160) on October 10, 2023 and a similar M1.6 (#8550) on November 2, 2023. This earthquake in Turkey is the largest aftershock within about 200 km of today's event since an M 5.3 on August 10, 2023. But the last such aftershock with larger magnitude was an immediate aftershock of M 6.0 on February 6, 2023. The mainshock was an M 7.8 on February 6, 2023.
Forecast 158386 had expected today's event in eastern Turkey within about
50 km of this epicenter was likely around November 24.

An M 5.3 was also recorded today in the region of northern Chile of Antofagasta.
GUC reported it was felt in Antofagasta and Tarapaca with maximum intensity IV at El Loa, III in Huara, Pica, Pozo Almonte, II in Alto Hospicio, Camina, Iquique, in Antofagasta with IV in Calama, Tocopilla, III in Maria Elena, Mejillones, Chile. NEIC reported this earthquake of M 5.3 in Antofagasta, Chile was felt with intensity II-III in the area(s) of Antofagasta, Chile. This event occurred at the height of Solar Flare 1980 and was near local solar noon at the time of the event. This suggests it may have been promoted by SFE from this flare. The last earthquake within about 150 km of this epicenter with equal or larger magnitude than M 5.3 was an M 5.4 to the east on March 26, 2023. At the time this summary noted:
"The strongest earthquake in the world today was an M 5.4 in northern Chile. NEIC reported it was felt with intensity II-III in Calama, Antofagasta and in Iquique, Tarapaca, Chile. A foreshock of M 4.6 was felt with intensity II in Diego de Almagro, Atacama, Chile. Today's M 5.4 is the strongest earthquake in the region of Antofagasta, Chile since an M 5.6 on December 10, 2022. At the time this summary noted:
"The strongest earthquake in the world today was an M 5.6 in Antofagasta, Chile. NEIC reported maximum intensity IV in Calama, Antofagasta and II-III in Iquique, Tarapaca and in Valparaiso in Vina del Mar and San Antonio, Chile. This earthquake was accompanied by the eruption of the Lascar Volcano in Antofagasta, Chile. This eruption involved smoke, ash and lava and is a major eruption of this volcano. Lascar is located at 23.37S 67.73W in Antofagasta and is the most active of the volcanoes in the northern Andes of Chile. Chile's National Geology and Mining Service reported the eruption began within minutes of local solar noon (12:36 pm) and may have been triggered by high tidal stresses with the full moon which maximize near this hour. Ash reached heights of 6000 meters above the volcano. While no damage has been reported, air traffic has been alerted to the ash plume and evacuations may eventually be required. The last major eruption of Lascar was in 1993 but minor eruptive cycles occurred in 2006 and 2015." (March 26, 2023)

A moderate earthquake of M 5.2 also occurred today in the region of Tajikistan.
A similar earthquake of M 5.2-5.3 hit this region on November 13, 2023. At this time this summary noted:
"To the east of the event in Turkey, an M 5.3 occurred near the time of the new moon in Tajikistan. The last earthquake of equal or larger magnitude in
Tajikistan was an M 5.3 on October 2, 2023 but the last of larger magnitude was an M 5.8 on March 22, 2023. At the time this summary noted:
"... tidal triggering of seismicity had been expected in this and previous issues of this summary with this new moon ...
An M 5.9 also occurred in Tajikistan today. NEIC reported it was felt with intensity V in Choruh-Dairon, Tajikistan with maximum intensity VI in Sulukfu, Os, Kyrgyzstan with IV in Khujand, Matcha, Kofarnihon, Dushanbe, Navabadski, Tajikistan and III in Bekobod, Taskent, Uzbekistan. NEIC reported the aftershock of M 4.5 in Tajikistan was felt with intensity II-III in the area(s) of Uzbekistan at Tashkent and Salor. While this epicenter is about 400 km northwest of the 7.2 in Tajikistan of February 23, 2023, it is likely related to regional stress redistribution related to that mainshock. The M 5.8 occurred within about an hour of local solar midnight and was probably also promoted by strong tidal, geomagnetic and GRB effects which maximized near this hour."

The strongest earthquake in the U.S. or Canada today was an M 4.2 in western Texas, EMSC reported this earthquake of M 4.2 in Western Texas was felt with intensity II-III in the area(s) of Western Texas in Ackerly. An earlier event about 200 km to the west of this occurred in western Texas of M 3.4 was felt with light intensity in Whites City, New Mexico and in Pecos, Texas. An M 4.0 hit this area of western Texas on November 4, 2023 but the strongest earthquake in the past 35 years in this area was an M 5.2 on December 16, 2022. At the time this summary noted:
"...represents a new area of seismic enhancement. The largest earthquake within about 100 km of today's epicenter in recent years included an M 4.0 on June 6, 2022 and an M 4.5 on December 28, 2021 - the only such events of M>=3.5 in this area in the past 35 years. Earthquakes in Texas with M>=5.4 have historically been rare. The only such event recorded in this state of equal or larger magnitude were an M 5.6-6.4 on August 16, 1931; an M 5.5 on June 17, 1959 and an M 5.7 on April 14, 1995. The events in 1995 and 1931 occurred in the western Permian Basin near the current series prior to today while the event in 1959 was in northern Texas near the Oklahoma border." (December 16, 2022)
Forecast 158367 had expected enhanced seismicity in this area was likely around
November 24. The M 4.2 epicenter is at the third node from the Mindanao M 6.9 of November 17 and may have been promoted by energy from that source.

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

STRONG GEOMAGNETIC STORM TEMPORARILY DAMPENS GLOBAL SEISMICIT?Y
EARTHQUAKE SUMMARY FOR NOVEMBER 22, 2023
It was a relatively quiet day in global seismicity. This is typical of the second and third days after the start of strong geomagnetic storms such as the current storm as noted in this and previous issues of this summary:
"The geomagnetic field saw minor storm conditions today. The AP level was 30. High latitudes saw major storm conditions with AP 60. Middle latitudes were at disturbed conditions with AP 17. This storm is the strongest ionospheric disturbance since AP reached 40 on November 6 and the most disturbed at high latitudes since high latitude AP reached 86 on October 28, 2023. This activity is likely to enhance global seismicity near the geomagnetic equator and at high latitudes with the potential to trigger strong earthquakes in that zone in the next several days." (November 21-23, 2023)
The strongest earthquakes in the world today were a pair of earthquakes in Indonesia and New Guinea - both of M 5.0. The event in New Guinea occurred near the current eruption of Ulawun Volcano in New Britain and was probably promoted by stress transfer from that eruption. Forecast 158272 had expected this event within about 100 km was likely around November 23.

The M 5.0 south of Timor was widely felt in the area. BMG reported this earthquake of M 5.1 in Timor, Indonesia was felt with intensity II-III in the area(s) of Timor, Indonesia in Tidak Ada Wilaah Terdampak. This is an unusual epicenter for a moderate quake. The last event within about 200 km of this epicenter was an M 5.2 on October 4, 2013 - an aftershock of an M 5.8 on April 19, 2013. At the time this summary noted:
"An earthquake of M 5.8-6.2 hit in the Banda Sea of Indonesia today. NEIC reported this earthquake was felt with intensity II in Darwin, Northern Territory, Australia. It is not uncommon for strong events in this area of the Banda Sea to be felt in the Darwin area. Local News also reported it was lightly felt in Maluku Island and on the island of Kai. BMG reported this earthquake was felt with intensity IV in Saumlaki, Maluku, in the Banda Sea. This may be an aftershock of an M 7.1 which hit this area to the west on December 10, 2012, and is the second strongest in the Banda Sea in the past two years." (April 19, 2013)
Forecast 158266 had expected this activity to the north was likely around November 23.

An earthquake of M 3.8 also shook much of Nepal today. It occurred near local solar midnight and may have been promoted by strong geomagnetic and/or tidal stresses which maximize near this hour.
NEIC reported this earthquake of M 3.8 in Nepal was felt with intensity II-III in the area(s) of Nepal. EMSC reported moderate intensity was felt in Nepal at Thankot, Sitapaila, Kathmandu, Lalitpur, Patan, Sainbu Bhainsepati, Madhyapur Thimi, Dhapasi, and Mahangkal.
EMSC reported moderate intensity was felt in Nepal at Thankot, Sitapaila, Kathmandu, Lalitpur, Patan, Sainbu Bhainsepati, Madhyapur Thimi, Dhapasi, and Mahangkal. Forecast 158063 had expected enhanced seismicity in this region of Nepal around November 18.

The strongest earthquake in the U.S. or Canada today was an M 4.3 in the Rat Islands, Aleutians, Alaska. It was not reported felt in this remote area. Recent earthquakes of equal or larger magnitude in this area of the Rat Islands occurred as an M 4.3 on November 14, 2023 and an M 5.1 on November 5, 2023. At that time this summary noted:
"The strongest earthquake in the U.S. or Canada today was an M 5.1 in the Rat Islands, Aleutians, Alaska. It was not reported felt in this remote area. This event occurred near local solar midnight and was probably promoted by the strong geomagnetic storm today (see above) which maximized at high latitudes near this hour. This is the strongest earthquake in the Rat Islands since an M 5.7 on June 8, 2023. At the time this summary noted in this regard:
"The strongest earthquake in the world today was an M 5.7 in the Rat Islands, Aleutians, Alaska. NEIC reported a report of VII intensity in the area generally light intensity II-III in this remote epicentral area. The mainshock was followed by aftershocks of M 4.6, 4.2 and 4.6 which were not felt. This is the strongest earthquake in the Rat Islands since an M 6.3 on December 14, 2022 and an M 6.3 a year ago on June 4, 2022. At that time this summary noted in this regard:
"The event of M 6.3 in the Rat Islands was not reported felt in this remote area. This is the strongest earthquake in the Rat Islands since an M 6.4 on April 2, 2019. These appear to be aftershocks of the M 7.9 that hit about 50 km southeast of today's epicenter on June 23, 2014. Today's event occurred near local solar noon and was likely promoted by high tidal stresses which maximize near this hour. It may also have been promoted by the recent geomagnetic storm." (November 5, 2023, June 8, 2023, June 5, 2022)
Forecast 158449 had expected today's event was likely within about 50 km in the

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

STRONG EARTHQUAKES IN HALMAHERA AND VANUATU
EARTHQUAKE SUMMARY FOR NOVEMBER 21, 2023
A pair of strong earthquakes were recorded today in Halmahera south of Mindanao, Philippines (M 6.0-6.6) and in Vanuatu (M 6.7). These occurred as a strong geomagnetic storm, the first in more than a week began and joined a string of moderate earthquake which followed the geomagnetic equator from Samoa, Vanuatu, Banda, Molucca and Halmahera (see today’s earthquake map below). They are near the geomagnetic equator and may have been promoted by stresses associated with that storm as noted in this summary as:
"The geomagnetic field saw disturbed conditions today. The AP level was 18. High latitudes saw minor storm conditions with AP 31. Middle latitudes were at disturbed conditions with AP 15. This storm continued into early November 22 with KP up to 7 around 03-08 UT. This activity is likely to enhance global seismicity near the geomagnetic equator with the potential to trigger strong earthquakes in that zone in the next several days. The AP at high latitudes and the global AP are the strongest disturbance in the geomagnetic field since AP reached 40 km November 6, 2023.
The strongest earthquake in the world today was an M 6.7 in central Vanuatu. This is the strongest earthquake within about 200 km of this epicenter in Vanuatu since an M 7.0 on January 8, 2023. At the time this summary noted in this regard:
"The strongest earthquake in the world today was an M 7.0 in central Vanuatu. NEIC reported it was felt with minor damage in Vanuatu in Sanma at Port Olry (VIII) and Luganville (VI) with intensity IV in Vila Shefa, Vanuatu. This earthquake occurred near local solar midnight and was probably promoted by strong tidal stresses with the full moon of January 6 as it occurred near a longitude of maximum stress with that event as previously noted in this summary
...
The last strong earthquake in central Vanuatu of M>=6.5 was an M 6.9 on August 18, 2021. The last earthquake within about 250 km of today's epicenter with M>=7 in the region was an M 7.0 on April 28, 2016 and prior to that an M 7.1 on October 20, 2015 near today's epicenter. The environmental conditions at the time of the event on October 20, 2015 in Vanuatu were similar to those today with stresses from a new moon..." (January 8, 2023)
Forecasts 158215 and 158484 had expected today's event within about 100 km was
likely around November 19.

A strong earthquake of M 6.0-6.6 was also recorded in the region of Halmahera, Indonesia today. NEIC reported this earthquake of M 6.0 in Halmahera was felt with intensity II-III in the area(s) of Halmahera. PHIVOLCS reported intensity II in the City of General Santos; Glan, Alabel, Malapatan, Malungon and Kiamba, Sarangani; Tupi, Tampakan, City of Koronadal and Tboli, south Cotabato and I in Polomolok, Surallah and Lake Sebu, South Cotabato; Maasim and Maitum, Sarangani.
BMG reported this event with M 6.6 was felt with intensity III in Kota Manado at Wenang, Tikala, Mapanget, Paal Dua; Toraja in Tikala; Halmahera in Jailolo, Lododa, Ibu Selatan, Sahu Timur, Galela, Kao, Malifut, Tobelo Tengah, Tobelo, Galela, Loloda, Kao and in Ternate at Pulau Batang Dua, Pulau Hiri. EMSC reported moderate shaking in the Philippines at General Santos City, and in Manado, Indonesia with strong shaking.
Today's event is the strongest recorded within about 200 km of this epicenter
in Halmahera since an M 7.0 on January 18, 2023 and before than an M 7.1 on November 14, 2019. Today's event occurred near local solar noon and was likely promoted by strong tidal stresses which maximize near this hour. It occurred in an area which has seen strong seismic enhancement in the past week including an M 6.8 in Mindanao to the north of this epicenter and several in Molucca and Halmahera of strong or moderately strong magnitude. When an M 7.1 hit the Banda Sea on November 8 this summary noted:
"The strongest earthquakes in the world today were a pair of strong to major earthquakes of M 6.7 and 7.1 in the Banda Sea, Indonesia. NEIC reported it was felt with maximum intensity III in the Banda Sea, Indonesia area. The mainshock of M 7.1 was preceded about a minute early by a foreshock of M 6.7 which was felt in the area with maximum intensity VI. These events were also felt in northern Australia at Darwin. BMG reported the mainshock of M 7.1 was felt with intensity up to V in the Tanimbar Islands. BMG reported this activity in the Tanimbar region was felt with intensity IV in Bandaneira, III in Maluku Tengah, Banda, Maluku Tenggara, at Kecil, Manyeuw, Hoat Sorbay, in Tanimbar at Tanimbar Selatan, Selaru, Wer Tamrian, Wer Maktian; in Seram Bagian in Maluku Barat Daya and in Kota Tual and many other communities experienced lesser shaking. No tsunamis were observed or expected with these events. A moderate foreshock hit the region yesterday and was reported in this summary as:
"The strongest earthquake near the geomagnetic equator in Indonesia today was an M 5.2 in the Banda Sea. EMSC reported this earthquake of M 5.2 in Banda Sea, Indonesia was felt with intensity II-III in the area(s) of Banda Sea, Indonesia in Dili, Timor. BMG reported intensity III-IV in Timur, Alor, Nusa, Tengara, Maluku, Tengah Selatan, among others. This follows a relatively quiet period in Indonesia over the past week and probably is the first salvo of enhanced seismicity in the area with the major geomagnetic storm of yesterday and today (see above). The last earthquake of M>=5.2 in the Banda Sea area was an M 5.8 on September 23, 2023." (November 8, 2023)
Likewise when an event of M 6.7 hit the area of Mindanao northwest of today's epicenter on November 17, this summary noted:
"This earthquake follows a series of earthquakes in Central Indonesia and southern Philippines of the past week which was addressed several days ago in this summary as:
"The strongest earthquake of the day in the world was an M 6.2 in Halmahera, Indonesia. BMG reported maximum intensity III at Banggai Tengah, Banggai Laut and Sulawesi with intensity II in Bolaang Mongondow at Lolayan Passi Timur, Bilaland and in Minahasa at Selatan, Utara, Tengara, and in Kota Bitung, Tomohon, Kotamobagu and Toraja Utara at Tikala. This earthquake continues a strong activation of the region of central and eastern Indonesia and southern Philippines which has been connected in this summary to the strong geomagnetic storm of the past several days as:
"This continues the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term." (November 9-12, 2023)
Further enhancement of seismicity in southern Philippines and central and eastern Indonesia is expected in the next several days especially near the geomagnetic equator and with the new moon which is expected to enhance global seismicity" (November 16, 17, 2023)
Forecast 158250 had expected today's event was likely within about 100 km of this epicenter around November 22.

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.

SECOND MODERATE QUAKE IN CENTRAL MID-ATLANTIC
EARTHQUAKE SUMMARY FOR NOVEMBER 20, 2023
The largest earthquake in the world today was an M 5.5 in the Central Mid-Atlantic. It was not reported felt in this remote area. This follows an M 5.3 recorded near this epicenter and reported on in the previous issue of this summary as:
"The second largest earthquake in the world today was an M 5.3 in the Central Mid-Atlantic. It was not reported felt in this remote area. This epicenter is nearly antipodal to a series of events in New Britain of the past week at 3S 151E where a major volcanic eruption of Mount Ulawun occurred today (see below). Similar events hit the area as an M 5.5 on January 3, 2023 and an M 5.3 on February 17, 2023 but the last of larger magnitude within about 200 km of this epicenter was an M 6.5 on August 30, 2020.
Forecast 157988 had expected today's event within about 10 km was likely around
November 19, 2023." (November 20, 2023)

The strongest earthquake in the U.S. or Canada today was an M 3.9-4.1 in Southeastern Alaska and the area of British Columbia, Canada. The M 4.1 occurred within minutes of local solar noon and may have been promoted by strong tidal stresses which maximize near this hour. The last earthquake with M>=4.1 within about 100 km of this epicenter near Yakutat, Alaska occurred as an M 5.3 a month ago on October 28, 2023. At the time this summary noted:
A series of earthquakes occurred today in southeastern Alaska. The largest of these were of M 5.1 and M 5.3. NEIC reported it was felt with maximum intensity IV in Alaska at Haines and Hoonah and II-III in Skagway, Elfin Cove, Douglas, Juneau, Sitka, and Angoon and in Whitehorse, Yukon, Canada and Fraser Lake, British Columbia, Canada and perhaps as far as Anchorage and Beaver, Alaska nearly 1000 km to the north. Aftershocks were felt with intensity II-III in Southeastern Alaska at Elfin Cove, Douglas, Juneau and in Whitehorse, Yukon, Canada. It is likely these events were promoted by tidal stresses with today's full moon and eclipse ...
Today's event in southeastern Alaska is the strongest within about 250 km of this epicenter since an M 6.2 and 5.3 on May 1, 2017 followed by aftershocks of M 5.6 and 5.7. At the time this summary noted in regard to this series:
" ... The only moderate seismicity in this year (2017) in the area prior to today occurred on January 16 with M 4.1 and 4.3. An M 6.2 hit the are 17 years ago on January 6, 2000. The M 6.3 in this region today is the strongest within about 200 km of this epicenter since an M 6.7 on July 1, 1973. Other events of M>=6.3 were recorded on July 10, 1958 (M 7.9); February 3, 1944 (M 6.4); October 24, 1927 (M 7.1); January 18, 1901 (M 7.1) and in September, 1899 (M 8.6). A strong aftershock is considered likely since it has been 44 years since the last such event in the region." (May 1, 2017, October 28, 2023)
Today's event is probably an aftershock of the M 5.3 on October 28, 2023.
Forecasts 158184 and 158452 had expected today's event was likely around November 18-22.

An earthquake of M 4.7-4.8 occurred today in the Tyrrhenian Sea west of Italy. Earthquakes in this area are generally at intermediate to deep focal depth (300-500 km depth) as was today's event, and are seldom felt at the surface. The last earthquake of equal or larger magnitude in this area within about 200 km of this epicenter was an M 5.8 on October 28, 2016. At the time this summary noted:
"A deep focus earthquake of M 5.8 occurred today in the Tyrrhenian Sea of Italy. It was reported felt with intensity II in Messina, Sicily, Italy. The depth of this earthquake suggests it may have been promoted by tidal stresses ..." (October 28, 2016)
Forecast 158093 had expected today's activity within about 100 km was likely around November 20. This epicenter is located at 103 degrees from the M 6.8 in Mindanao of November 17, 2023 and may have been promoted by energy from that source. An unusual event of M 3.6 also occurred in France today at this distance from Mindanao.

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 IN HOKKAIDO, JAPAN
EARTHQUAKE SUMMARY FOR NOVEMBER 19, 2023
The strongest earthquake in the world today was an M 5.8 in Hokkaido, Japan. NEIC reported it was felt with intensity up to IV in Yokohama, Japan. This epicenter is at the ninth node (40 degrees) from the M 6.9 in Mindanao of November 17 and was probably promoted by energy from that source. An earthquake of M 5.8 also occurred near this epicenter on August 11, 2023. At the time this summary noted:
"The strongest earthquake in the world today was an M 5.8 in Hokkaido, Japan. NEIC reported it was felt with intensity III in Hokkaido at Saporo, Hakodate and in Aomori in Hachinohe and Misawa. The last earthquake recorded in the region of Hokkaido, Japan with M>=5.8 was an M 6.2 on June 11, 2023. At the time this summary noted:
"Today's M 6.2 in Hokkaido is the strongest recorded in southern Hokkaido within about 200 km of this epicenter since an M 6.2 on December 19, 2021 and prior to that an M 6.6 near today's
epicenter on September 5, 2018." (June 11, August 11, 2023)
Today's event follows a series of moderate quake to the north in the Kuril Islands which was commented on in this summary in the previous as:
"A series of moderate earthquakes occurred throughout the Kuril Islands today. While not unusual individually, this broad activation of the region suggests a regional stress which may later include a strong regional event." (November 19, 2023)
Forecast 158135 had expected enhanced seismicity in this area of Hokkaido was
likely in mid-November.

The second largest earthquake in the world today was an M 5.3 in the Central Mid-Atlantic. It was not reported felt in this remote area. This epicenter is nearly antipodal to a series of events in New Britain of the past week at 3S 151E where a major volcanic eruption of Mount Ulawun occurred today (see below). Similar events hit the area as an M 5.5 on January 3, 2023 and an M 5.3 on February 17, 2023 but the last of larger magnitude within about 200 km of this epicenter was an M 6.5 on August 30, 2020.
Forecast 157988 had expected today's event within about 10 km was likely around
November 19, 2023.

Mount Ulawun erupted today in New Britain, Indonesia. The Volcanic Ash Advisory Center in Darwin Australia reported the eruption began about 06:30 UT on November 20 and involved volcanic ask sent to heights of up to 50,000 feet (15,000 meters). The risk of a tsunami is being evaluated and could reach as far as Japan. Ulawun Volcano is located at 5S 151.3E. This epicenter has seen a series of moderate earthquakes in the past several days which were probably precursory activity to today's eruption. Forecast 158010 had expected this activity was likely in mid-November.

In other volcanic news, the anticipated eruption in Iceland is still considered likely in the next several days by officials at the Icelandic Meteorological Office as magma slowly moves towards the surface. More than 500 earthquakes were recorded today (the largest of which was M 2.7) in Iceland around 7 am (9:00 UT) and may be precursory to the anticipated eruption. Residents of Grindavik have been evacuated and a state of emergency near Mount Fagradalsfjall Volcano is still in effect. Forecast 158195 had expected this activity in mid-November.

An earthquake of M 4.7-4.8 occurred today in the Tyrrhenian Sea west of Italy.
Earthquakes in this area are generally at intermediate to deep focal depth (300-500 km depth) as was today's event, and are seldom felt at the surface. The last earthquake of equal or larger magnitude in this area within about 200 km of this epicenter was an M 5.8 on October 28, 2016. At the time this summary noted:
"A deep focus earthquake of M 5.8 occurred today in the Tyrrhenian Sea of Italy. It was reported felt with intensity II in Messina, Sicily, Italy. The depth of this earthquake suggests it may have been promoted by tidal stresses ..." (October 28, 2016)
Like the M 4.4 off northern California and Iceland, this event in the Tyrrhenian Sea is located a 103 degrees from the M 6.9 in Mindanao of November 17, 2023 and was probably promoted by energy from that source.
Forecast 158093 had expected today's activity within about 100 km was likely around November 20.

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

STRONG QUAKE IN NORTHERN MARIANA ISLANDS
EARTHQUAKE SUMMARY FOR NOVEMBER 18, 2023
The strongest earthquake in the world today was an M 5.9 in the Pagan Region of the northern Mariana Islands. This is the largest earthquake to have occurred within about 200 km of this epicenter since an M 6.2 on June 13, 2020. Most strong earthquakes in this region – including today's and the event in June, 2020 occur at deep focus around 400-600 km depth and do not have serious effects at the surface. At the time of the M 6.2 in June, 2020 this summary noted:
"The M 6.2 in the northern Mariana Islands was not reported felt. It occurred at a depth greater than 620 km in a sparsely populated area. The last earthquake within about 200 km of this epicenter with M>=6.2 was an M 6.4 on June 28, 2019 and an M 7.7 on July 29, 2016." (June 13, 2020)
It occurred near local solar noon and may have been promoted by strong tidal stresses which maximize near this hour. Forecast 158042 had expected today's event within about 100 km was likely in the northern Marianas around November 18, 2023.

A series of moderate earthquakes occurred throughout the Kuril Islands today. While not unusual individually, this broad activation of the region suggests a regional stress which may later include a strong regional event. Forecasts 158158 and 158159 had expected this activity around November 16-18, 2023.

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

STRONG EARTHQUAKE IN MINDANAO CONTINUES REGIONAL SEISMIC ENHANCEMENT
EARTHQUAKE SUMMARY FOR NOVEMBER 17, 2023
The strongest earthquake in the world today was an M 6.7-6.9 in Mindanao, Philippines. EMSC reported strong shaking in Mindanao at General Santos City, Carpenter Hill, Koronadal, Digos, Bato, Davao, Kabacan, Samal, Mati, Kapatagan, Cagayan de Oror, Gingoog, and in Indonesia at Manado, and lightly in Malaysia.
PHIVOLCS reported maximum intensity VII in Glan, Sarangani; VI in Koronadal and Polomolok, South Cotabato and teh City of General Santos with V in Pantukan, Davao de Oro, City of Taggum, Davao del Norte; Jose Abad Santos, Davao Ocidental; Alabel, Kiamba, Maitum, Maasim and Malungon , Sarangani; Banga, Lake Sebu, Tampakan and Tup, South Cotabato and in the City of Tacurong, Sultan Kudarat. It was also felt with intensity IV in the City of Zamboanga, Surigao del Sur, Maguindanao, Agusan Del Sur and II in Bukidnon, City of Butuan Sulu and Basilan. NEIC reported it was felt with intensity up to VIII in Mindanao at Burias. Press reports indicated considerable damage including more than seven people killed by falling debris during the quake. A crane collapsed killing several people. Much of the damage occurred in General Santos City about 100 km from the epicenter where a ceiling at a shopping center collapsed. No tsunami was observed or expected with this quake. Power was temporarily out in the epicentral area. Many injuries were reported and building an ceiling collapses were reported throughout the area. BMG reported this earthquake with M 6.9 at 5.5N 125.2E with light to moderate shaking of II-IV in islands south of Mindanao in Indonesia including at Tahuna, Morotal Selatan, Boa-Sio and Manado among others. This earthquake follows a series of earthquakes in Central Indonesia and southern Philippines of the past week which was addressed several days ago in this summary as:
"The strongest earthquake of the day in the world was an M 6.2 in Halmahera, Indonesia. BMG reported maximum intensity III at Banggai Tengah, Banggai Laut and Sulawesi with intensity II in Bolaang mongondow at Lolayan Passi Timur, Bilaland and in Minahasa at Selatan, Utara, Tengara, and in Kota Bitung, Tomohon, Kotamobagu and Toraja Utara at Tikala. This earthquake continues a strong activation of the region of central and eastern Indonesia and southern Philippines which has been connected in this summary to the strong geomagnetic storm of the past several days as:
"This continues the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term." (November 9-12, 2023)
Further enhancement of seismicity in southern Philippines and central and eastern Indonesia is expected in the next several days especially near the geomagnetic equator and with the new moon which is expected to enhance global seismicity" (November 16, 2023)
The last earthquake within about 200 km of today's epicenter with M>=6.7 occurred on April 28, 2017. At the time this summary noted:
"A major earthquake of M 6.8 (EMSC) to 7.2 (PHIVOLCS) occurred in the area of Mindanao, Philippines today. It was widely felt in the area with minor damage. This event is part of the series of strong earthquakes from Mindanao to central Mindoro, Philippines which began after the M 6.6 in Botswana on April 3. ...
NEIC reported the earthquake of M 6.8 in Mindanao was felt with intensity VII in Maitum and San Jose, General Santos City, with intensity VI in Katangawan, Southern Mindanao. Intensity V was reported from Southern Mindanao at Buayan, Silway, Polomolok, Malungon, Koronadal, Balutakay, Digos, Limao, and IV in Zamboanga, Davao, Ula, Inawayan, and II-III in Kapatan, Palian, Norala, Kalawag, Makilala, Lacson, Salimbao, Mawab, Barra, Malitbog, Lumbayao, Tiayon and as far as Manado, Sulawesi, Indonesia. ... The last earthquake within about 250 km of this epicenter with M>=6.8 was an M 7.4 and 7.6 on July 23, 2010. The last within about 140 km of this epicenter was an M 7.1 on February 5, 2005." (April 28, 2017)
Forecast 157996 had expected this event in this area was likely in mid-November within about 100 km of today's epicenters.

The strongest earthquake in the U.S. or Canada today was an M 4.7 in the Gulf of Alaska. It was not reported felt in this remote area. Earthquakes of M>=4.7 in the Gulf of Alaska in the past three years within about 200 km of today's epicenter occurred on October 24, 2020 (M 4.8) and February 3, 2022 (M 4.9).
No earthquakes of M>=5 have occurred in this area since an M 5.1 on March 20, 2020. These appear to be aftershocks of the great quake of M 7.9 on January 23, 2018. At the time of the February, 2022 this summary noted:
"The largest earthquakes in the U.S. or Canada today occurred in the region of Alaska. This is not uncommon but the number of events of M>=4.3 (four) and their variety of locations (South of Alaska - M 4.9; Rat Islands - M 4.6; Andreanof
Islands - M 4.4 and Fox Islands - M 4.3) within the state were unusual. The largest of these was an M 4.9 followed 14 minutes later by an M 3.4 in the Gulf of Alaska. This is an aftershock of the M 8.1 which hit this area on January 23, 2018. It is the largest such aftershock since an M 5.1 which occurred March 20, 2020 nearly two years ago." (February 3, 2022)
Forecast 158197 had expected today's quake was likely within about 200 km around November 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.

The strongest earthquake in the world today was an M 5.7 in the area of Myanmar. NEIC reported it was felt with damage and intensity up to VIII in Keng Tung, Myanmar. EMSC reported strong shaking in Thailand at Mae Fa Luang, Chiang Rai, Rop Wiang, San Phisuea, Chiang Mai, Saraphi, Wiang Nuea, Tha Pha, and in Hanoi, Vietnam. NEIC reported an aftershock of M 4.5 in Myanmar was felt with intensity II-III in the area(s) of Myanmar in Keng Tung. Local News reported the quake was felt in the counties of Vietnam, Laos, Myanmar, Thailand and China. It was felt in the Chiang Rai districts of Mae Lao, Muang, Phan, Mae Suay, and in the Muang district of LLamphun and some parts of Nan, and Lak in districts of Bangkok. It was also felt in Mae Hong Son in the north as well as Udon Thani and Khon Kaen in the northeast and Mae Suai. A survey of damages has not yet been completed but no extensive damage has been reported at this time to reservoirs or dams. An M 6.1 hit near this epicenter on May 5, 2014 causing one death, 107 injuries and
extensive damage to more than 15,000 buildings. Other noteworthy recent earthquakes hit the area on March 24, 2011 killing on in northern Thailand and on May 16, 2007 in Laos. That event damaged schools, hospitals ad hitoric buildings and landmarks. Today's event in Myanmar may have been promoted by stresses from a tropical cyclone to the southwest in the Bay of Bengal as noted in previous issues of this summary:
A tropical cyclone may be forming in the Bay of Bengal east of Peninsular India. This system is currently at 18N 87E and moving to the NNE with winds up to 32 kts." (November 15-16, 2023)

The strongest earthquake in the U.S. or Canada today was an M 4.5 in the Fox Islands, Aleutians, Alaska. This is the strongest earthquake in the western Fox Islands since an M 5.6 on October 12, 2023. At that time this summary had noted:
"The strongest earthquake in the U.S. or Canada today was an M 5.6 in the western Fox Islands, Aleutians, Alaska. NEIC reported it was felt with intensity IV in Atka, Alaska. The last earthquake within about 150 km of this epicenter with equal of larger magnitude occurred on September 27, 2020 and October 26, 2019 with M 5.6 and 5.9.
It is likely that this event was promoted by strong tidal stresses associated with upcoming new moon and eclipse which passes over this epicenter early on October 14. Further enhanced seismicity in the Aleutians is likely with the new moon and eclipse in the next several days. This could include a strong earthquake." (October 12, 2023)
Forecast 158170 had expected this event was likely within about 100 km around
November 17.

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

UNUSUAL EARTHQUAKE OF M 3.6 SHAKES ILLINOIS; STRONG QUAKE SOUTH OF MINDANAO
EARTHQUAKE SUMMARY FOR NOVEMBER 15, 2023
An unusual earthquake of M 3.6 was widely felt in the area of Illinois today. NEIC reported intensity up to V in the epicentral area including at Standard, Illinois. The last earthquake in this region within about 200 km of today's epicenter in Illinois with magnitude greater than or equal to M 3.6 was recorded by NEIC to have occurred on with M 3.8 on February 10, 2010. At the time this summary noted in this regard:
"The earthquake with epicenter in Illinois was felt throughout much of the
eastern United States. Intensity I-III was reported to NEIC from Massachusetts,
New Jersey, New York, Maryland, North Carolina, Georgia, Tennessee, Kentucky,
Ohio, Indiana, Michigan, Soouth Dakota, Minnesota, Iowa, Wisconsin, Illinois, Missouri, Nebraska, Arkansas and Colorado. ...
The only comparable earthquake in the region in the past 20 years occurred on June 28, 2004 with M 4.2. This earthquake in 2004 was felt with intensity V in Earlville and Ottawa, Illinois and as far as Indiana, Iowa, Michigan, Missouri and Wisconsin. It was followed several hours later by an earthquake of M 6.8 in the Queen Charlotte Islands. It is not uncommon for strong earthquakes on the plate boundary to follow moderate intraplate earthquakes in the United States. We have described this as a creaking of the plate...." (February 10, 2010)
Forecasts 157817 and 158096 had expected enhanced seismicity in this area was likely in mid-November.

The strongest earthquake of the day in the world was an M 6.2 in Halmahera, Indonesia. BMG reported maximum intensity III at Banggai Tengah, Banggai Laut and Sulawesi with intensity II in Bolaang mongondow at Lolayan Passi Timur, Bilaland and in Minahasa at Selatan, Utara, Tengara, and in Kota Bitung, Tomohon, Kotamobagu and Toraja Utara at Tikala. This earthquake continues a strong activation of the region of central and eastern Indonesia and southern Philippines which has been connected in this summary to the strong geomagnetic storm of the past several days as:
"This continues the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term." (November 9-12, 2023)
Further enhancement of seismicity in southern Philippines and central and eastern Indonesia is expected in the next several days especially near the geomagnetic equator and with the new moon which is expected to enhance global seismicity as:
"The new moon arrived on November 13, 2023 at 09:27 UT. Longitudes at local solar noon were near 37 East while those at local solar midnight are near 143 West longitude. These include Hawaii and areas of eastern Alaska and western Canada and to a lesser extent areas off the coast of Oregon and California while in the east they include Eastern Turkey where an M 7.7 hit on February 6, 2023 as well as Ethiopia and areas off southern Africa. These and surrounding areas are the most likely to see tidally enhanced seismicity at this time. A moderate to large aftershock is possible in Turkey at this time." (November 12-16, 2023)
The last earthquake of M>=5.7 within about 200 km of today's epicenter was an M 6.3 about 200 km to the south on June 30, 2004. This event, like today's, followed a strong geomagnetic storm and a strong enhancement of seismicity near the geomagnetic equator. At the time this summary noted:
"A series of moderate to strong earthquake occurred today within the region bounded by 20 degrees north of south of the equator. The strongest of these events was an M 6.3 in the Minahassa Peninsula area of Sulawesi at 0.9 North latitude, the strongest in that are in more than three years (see below). The other major activity of the day also occurred near the equator. ...
The earthquake in Sulawesi of M 6.3 was reported by the Jakarta Post as being felt in Manado and is the strongest in the region since an M 7.1 on Feb. 24, 2001 to the east of today's earthquake and an M 7.6 on May 4, 2000 to the southwest. While no reports of damage are currently available, this size earthquake may have done damage in the epicentral area. The last event in the area which was similar to today's in magnitude occurred on Oct. 18, 2003 with M 6.3-6.4." (June 30, 2004)

A series of moderate earthquakes also occurred in the Fiji Islands and to the south of the Fiji Islands. This included earthquakes of M 4.9, 5.1, 4.8 and 4.5 which had been forecast is #s 158225, 157967 and 158226 to occur in mid-November. This enhanced seismicity in the Fiji Islands was probably promoted by the passage of Tropical Cyclone Mal through the region today as noted in this and previous issues of this summary:
"TD MAL continued today in the area of Tonga with winds up to 65 kts. It is expected to track to the southeast over the next several days passing through Fiji and Tonga where it may promote moderate to large earthquakes. It is expected to dissipate over the next day." (November 13-17, 2023)

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

STRONG QUAKES CONTINUE IN INDONESIA
EARTHQUAKE SUMMARY FOR NOVEMBER 14, 2023
The current seismic enhancement in Indonesia continued today with two strong earthquakes - an M 6.1 south of Sumatra and an M 5.9 in Papua New Guinea.
The strongest earthquake in the world today was an M 6.1 south of Sumatra and India in the South Indian Ocean. It was not reported felt in this remote area.
The earthquake in the South Indian Ocean of M 6.1 was not reported felt in this area. It occurred near local solar noon and was probably promoted by tidal stresses with the new moon which maximize near this hour. This is the strongest earthquake within about 300 km of this epicenter in the South Indian Ocean in at least 35 years. Comparable events occurred about 400 km northeast of today's epicenter with M 6.4 on November 29, 1999 and 24 year ago on November 15, 1999 with M 7.0.
O: 14NOV2023 07:00:58 4.0S 87.1E MW=6.1 EMSC SOUTH INDIAN OCEAN
The strongest earthquake felt in the world today was an M 5.9 in Papua New Guinea. NEIC reported it was felt with intensity III-IV in Papua at Finschhafen.
This is the strongest earthquake within about 200 km of this epicenter since an M 6.3 on April 19, 2023. Events of M 6.7 and M 6.9 hit about 250 km northwest of today's epicenter on October 7, 2023. At the time this summary noted:
"The strongest earthquake in the world today was an M 6.9 in Papua New Guinea.
It was followed by an M 6.7 and several moderate events of M>=5. An M 5.1 aftershock was felt in Madang and Port Moresby, Papua New Guinea. Other events in the series were not initially given intensities by NEIC however some felt data comes from Madang, PNG. No tsunami was reported as this epicenter is inland near the coast." (October 7, 2023)
Forecast 158010 had expected this event was likely within about 100 km of this epicenter around November 17.

GLOBAL SEISMIC ENHANCEMENT WITH NEW MOON
EARTHQUAKE SUMMARY FOR NOVEMBER 13, 2023
Global seismicity today showed an increase in larger events including an M 6.0
southwest of the area of Sumatra, Indonesia; an M 5.7 in the Kermadec Islands, New Zealand and an M 6.1 in Papua New Guinea, Indonesia. The seismic forecast for the time around this new moon had read:
"The new moon arrived on November 13, 2023 at 09:27 UT. Longitudes at local solar noon were near 37 East while those at local solar midnight are near 143 West longitude. These include Hawaii and areas of eastern Alaska and western Canada and to a lesser extent areas off the coast of Oregon and California while in the east they include Eastern Turkey where an M 7.7 hit on February 6, 2023 as well as Ethiopia and areas off southern Africa. These and surrounding areas are the most likely to see tidally enhanced seismicity at this time. A moderate to large aftershock is possible in Turkey at this time." (November 10-14, 2023)
The strongest earthquake in the world today was an M 6.1 in Papua New Guinea. NEIC reported it was felt with intensity IV in Rabaul, PNG. This occurred within about 1.5 hours of the new moon and may have been promoted by tidal stresses with that alignment (see above). It continues strong sequence of moderate earthquakes in the region which was addressed in the previous issue of this summary as:
"The strongest earthquake in the world today was an M 5.8 in Papua New Guinea. BMG reported iit was felt with intensity IX in Lerch, Jayapura, Papua; IV in Station Senggi, Keerom, Papua and III in Kaureh, Airu, in Keerom at Waris, Arso, Senggi, Web, Towe, Arso Barat, Yalfi, Kaisenar in Pengusingan Binting at Borne, Aboy, Batani, Murkim, Mofinop, Teiraplu, Nongme; in Yalukimo at Ubalihi, Talambo, Endomen, Kona and in Yalimo at Benawa. In the previous issue of this summary this activity was addressed as:
"The strongest earthquake in the world today was an M 5.9 in New Ireland. This is the strongest earthquake in New Ireland since an M 6.0 on March 7, 2023.
At the time this summary noted:
"A series of moderately large to strong earthquakes occurred today with the full moon a possible trigger for this seismicity. A second promoter was the current geomagnetic storm. This can be seen as the larger events today occurred in three categories. Category 1 was the most active and followed the geomagnetic equator around the earth. Events of M 6.0 hit near the geomagnetic equator today in Mindanao, Philippines (M 6.0-6.2), New Britain (M 6.0) and the Solomon Islands (M 6.0) with lesser magnitude in the Molucca Sea (M 5.4), Andaman Islands (M 4.9), Central Peru (M 4.7) and Turkey (M 4.5, 4.7). Category 2 events occurred at high latitudes and included, among others,
... The last earthquake of M>=6 in the New Ireland region within about 250 km of today's epicenter was an M 6.3 on November 30, 2021." (November 11, 13, 2023, March 7, 2023)
Forecast 158010 had expected today's activity within about 25 km was likely around
November 15, 2023.

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

An earthquake of M 5.7 also occurred today near the time of the new moon and local solar midnight in the Kermadec Islands. It was not reported felt in this remote region. This may be an aftershock of an M 6.1 northeast of this epicenter on October 23, 2023. At the time this summary noted:
"The strongest earthquake in the world today was an M 6.1 in the Kermadec Islands. It was preceded by an M 5.1 foreshock and followed by an M 4.5 which followed near local solar noon while the M 6.1 occurred near local solar midnight. It is likely that this activity was promoted by tidal stresses which maximize near these times. The last earthquake in the Kermadec Islands of M>=6 occurred as an M 6.6 on September 8, 2023." (October 23, 2023)
Forecast 158234 had expected today's event in this region was likely around November 13.

An M 4.6 also occurred today in the border region of Turkey and Iran. NEIC reported this earthquake of M 4.6 in Azerbaijan was felt with intensity II-III in the area(s) of Azerbaijan in Sharur City. EMSC reported this earthquake of M 4.8 on the Turkey-Iran border was felt with intensity II-III in the area(s) of on the Turkey-Iran border in Iran at Maku, Seyah Cheshmeh, and in Turkey at Dogubauazit, iand in Armenia at Yerevan, Prroshyan and K'anak'erravan.
This is at the maximum tidal stress longitude (see above) with today's new moon and was probably promoted by tidal stresses. Forecast 158124 had expected this activity was likely within about 200 km of this epicenter around November 17.

To the east of the event in Turkey, an M 5.3 occurred near the time of the new moon in Tajikistan. The last earthquake of equal or larger magnitude in Tajikistan was an M 5.3 on October 2, 2023 but the last of larger magnitude was an M 5.8 on March 22, 2023. At the time this summary noted:
"... tidal triggering of seismicity had been expected in this and previous issues of this summary with this new moon ...
An M 5.9 also occurred in Tajikistan today. NEIC reported it was felt with intensity V in Choruh-Dairon, Tajikistan with maximum intensity VI in Sulukfu, Os, Kyrgyzstan with IV in Khujand, Matcha, Kofarnihon, Dushanbe, Navabadski, Tajikistan and III in Bekobod, Taskent, Uzbekistan. NEIC reported the aftershock of M 4.5 in Tajikistan was felt with intensity II-III in the area(s) of Uzbekistan at Tashkent and Salor. While this epicenter is about 400 km northwest of the 7.2 in Tajikistan of February 23, 2023, it is likely related to regional stress redistribution related to that mainshock. The M 5.8 occurred within about an hour of local solar midnight and was probably also promoted by strong tidal, geomagnetic and GRB effects which maximized near this hour." (March 23, 2023)
Forecast 158089 had expected today's event in Tajikistan was likely within about
100 km around November 15.
NEIC reported this earthquake of M 5.3 in Tajikistan was felt with intensity II-III in the area(s) of Tajikistan.

The strongest earthquake in the U.S. or Canada today was an M 4.4 in the eastern Andreanof Islands, Aleutians, Alaska. NEIC reported it was felt with intensity IV in Atka, Alaska. Recent earthquakes in the eastern Andreanof Islands of larger magnitude included an M 5.0 on November 3 and an M 6.4-6.7 on October 16, 2023. At the time of the November 3 event this summary noted:
"The strongest earthquake in the U.S. today was an M 5.0 in the Aleutians near Atka, Alaska where it was lightly felt. An M 6.5-6.7 hit about 200 km west of this on October 16, 2023 but this is the strongest earthquake within 200 km of this epicenters in the Andreanof Islands since an M 5.1 on January 26, 2023."

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

MODERATELY STRONG QUAKES CONTINUE IN NEW GUINEA
EARTHQUAKE SUMMARY FOR NOVEMBER 12, 2023
The strongest earthquake in the world today was an M 5.8 in Papua New Guinea. BMG reported it was felt with intensity IX in Lerch, Jayapura, Papua; IV in Station Senggi, Keerom, Papua and III in Kaureh, Airu, in Keerom at Waris, Arso, Senggi, Web, Towe, Arso Barat, Yalfi, Kaisenar in Pengusingan Binting at Borne, Aboy, Batani, Murkim, Mofinop, Teiraplu, Nongme; in Yalukimo at Ubalihi, Talambo, Endomen, Kona and in Yalimo at Benawa. In the previous issue of this summary this activity was addressed as:
"The strongest earthquake in the world today was an M 5.9 in New Ireland. This is the strongest earthquake in New Ireland since an M 6.0 on March 7, 2023.
At the time this summary noted:
"A series of moderately large to strong earthquakes occurred today with the full moon a possible trigger for this seismicity. A second promoter was the current geomagnetic storm. This can be seen as the larger events today occurred in three categories. Category 1 was the most active and followed the geomagnetic equator around the earth. Events of M 6.0 hit near the geomagnetic equator today in Mindanao, Philippines (M 6.0-6.2), New Britain (M 6.0) and the Solomon Islands (M 6.0) with lesser magnitude in the Molucca Sea (M 5.4), Andaman Islands (M 4.9), Central Peru (M 4.7) and Turkey (M 4.5, 4.7). Category 2 events occurred at high latitudes and included, among others,
... The last earthquake of M>=6 in the New Ireland region within about 250 km of today's epicenter was an M 6.3 on November 30, 2021." (November 11, 2023, March 7, 2023)
Forecast 158010 had expected today’s activity within 25 km around November 15.

The strongest earthquake in the U.S. or Canada today was an M 4.6 in the Fox Islands, Aleutians, Alaska. NEIC reported it was lightly felt in Akutan, Alaska.
This follows a similar M 4.5 near this epicenter of November 12, 2023. At the time (in the previous issue of this summary) it was noted as:
"The strongest earthquake in the U.S. or Canada today was an M 4.5 in the Alaska Peninsula/Unimak Island, Alaska. NEIC reported it was lightly felt in the area of Sand Point, Alaska. An M 4.5 was also located in Alaska today in the Fox Islands, Aleutians. It was not reported felt in that remote area. The M 4.5 in the Fox Islands is the largest within about 150 km of that epicenter since an M 4.5 on July 30 while the event in the area south of Alaska last saw an M 4.5 or greater event within about 150 km of today's epicenter on March 7, 2023 (M 4.5). Forecasts 158185 and 158167 had expected today's activity in these region was likely around November 12-13." (November 12, 2023)

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

MODERATE QUAKES CONTINUE IN SOUTHWEST PACIFIC
EARTHQUAKE SUMMARY FOR NOVEMBER 11, 2023
The southwest Pacific continued to see the world's strongest seismicity today.
Moderately large events occurred in New Ireland (PNG) with M 5.9; as aftershocks
in the Banda Sea (M 5.7) and in Vanuatu (M 5.5). These areas are near the geomagnetic equator and may have been promoted by the strong geomagnetic storm of the past several days as noted in previous issues of this summary:
"... this is the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term." (November 8-9, 2023)
The strongest earthquake in the world today was an M 5.9 in New Ireland. This is the strongest earthquake in New Ireland since an M 6.0 on March 7, 2023.
At the time this summary noted:
"A series of moderately large to strong earthquakes occurred today with the full moon a possible trigger for this seismicity. A second promoter was the current geomagnetic storm. This can be seen as the larger events today occurred in three categories. Category 1 was the most active and followed the geomagnetic equator around the earth. Events of M 6.0 hit near the geomagnetic equator today in Mindanao, Philippines (M 6.0-6.2), New Britain (M 6.0) and the Solomon Islands (M 6.0) with lesser magnitude in the Molucca Sea (M 5.4), Andaman Islands (M 4.9), Central Peru (M 4.7) and Turkey (M 4.5, 4.7). Category 2 events occurred at high latitudes and included, among others,
... The last earthquake of M>=6 in the New Ireland region within about 250 km of today's epicenter was an M 6.3 on November 30, 2021." (March 7, 2023)

Aftershocks of the M 7.1 in the Banda Sea of November 8 also continued today with the maximum event of M 5.7 having been forecast in 158000 to occur in mid-November. This summary has covered this sequence extensively including in the previous issue as:
"The strongest earthquakes in the world today were an M 5.9 and M 6.2 aftershock in the Banda Sea region of Indonesia. BMG reported they were felt with intensity III in Maluku Tengah at Banda and II in Tanimbar at Wer Maktian, Tanimbar, Yaru, Wuar Labobar, Kormomolin, Niruamas, molu Maru; in Seran at Pulau Gorom, Wakate, Pulau Panjang, Teor, Gorom Timur and in Maluku at Damer. The M 6.2 was felt with intensity III in Maluku, Tanimbar and II in Seram, Ambon, Tual. This activity is aftershocks of the M 7.1 of November 8 in the Banda Sea." (November 11, 2023)

A series of moderate to large earthquakes have occurred in Vanuatu since Tropical Cyclone hit the area in late October. This included an M 5.7 in southern Vanuatu on November 5; and M 5.6 in northern Vanuatu on October 28 and an M 6.0 in Southern Vanuatu on October 29. At the time of these events this summary noted the coincidence with the passage of TC Lola as:
"The strongest earthquakes in the world today were an M 6.0 and M 5.6 in Southern Vanuatu. NEIC reported it was felt with intensity VI in Vanuatu at Isangel and III in Vila Shefa with II-III in New Caledonia at We Iles, and Noumea. This was likely promoted by the passage of a strong Tropical Cyclone (Lola) through the area over the past several days as noted in previous issues of this summary:
"Tropical Cyclone Lola (01P) continued over central Vanuatu today with winds up to 35 kts. This system is moving to the south and west. Some increases in seismicity in Vanuatu likely with this storm including a possible strong regional earthquake in the next three days." (October 25-28, 2023)
Today's M 6.0 in southern Vanuatu is the strongest since events of M 6.0-6.1 on September 28 and September 21, 2023." (October 28, 2023)
Forecasts 157950 had expected today's activity in Vanuatu was likely around November 7-9.

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

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

IMMINENT ERUPTION IN ICELAND?
EARTHQUAKE SUMMARY FOR NOVEMBER 10, 2023
An imminent eruption is possible in the area near Reykjavik, Iceland. Earthquakes today included an M 5.0 and 5.1 in the region of Grindavik, Iceland. This town of about 3500 has been ordered evacuated due to the likelihood of this eruption. EMSC reported these events were felt with strong intensity in Mosfellsbaer, Kopavogur, Keflavik, Suournesjabaer, Seltjarnarnes, Reykjavik, among others. This continues the current series of eruptions which began in 2021 - part of a sequence that occurs with about 700 year intervals and can last as long as 100 years. In this area of Iceland this involves motions between the North American tectonic and the European tectonic plates. Initial lava flows can be up to 100 feet per minute – faster than walking pace. There area some infrastructure near the site of this imminent eruption include the town of Grindavik several km away and a power plant and roads which could be damaged in an eruption. Several roads were actually reported damaged near Grindavik today by earthquakes.
Following is a listing of events in this Iceland swarm today of M>=4.0. A more detailed listing of events of M>=3.5 can be found in the EUROPE section of this summary.
Forecast 158195 had expected today's activity in Iceland was likely around November 12. The last earthquakes in Iceland with M>5.2 occurred in March and April 2021 and on October 20, 2020 (M 5.0). At the time this summary noted:
"An M 5.6 earthquake in Iceland today was accompanied by a series of lighter shocks. The mainshock was reported felt in southwestern Iceland with intensity V in Keflavik and IV in Harnarfjordur, Gardabaei, Alflanes, Kopavogur, Seltjarnarnes, Reykajik, Grundarhverfi and III in Mosfellsbaer, and Vogar.
This earthquake occurred within minutes of local solar noon and was likely promoted by high tidal stresses of the new moon which maximize near this time. This is the strongest earthquake in southern Iceland within about 200 km of this epicenter since an M 6.3 more than 12 years ago on May 29, 2008. Other such events occurred in 1998 and 2000. It is likely that this was triggered by energy from the Alaska Peninsula quake of M 7.5 yesterday combined with high tidal stresses and by the geomagnetic storm of the past day." (October 20, 2020)

An unusually large M 5.0 also shook the area of the Dominican Republic today. NEIC reported it was felt with maximum intensity up to VI in Las Matas de Santa Cruz. The mainshock was preceded by an M 3.6 in the Mona Passage. EMSC reported strong intensity in the Dominican Republic at San Fernando de Monte Cristi, Cana Chapeton, Mao, Moncion, Amima, Imbert, Pignon, Haiti, Santiago de los Caballeros, Puerto Plata, Santiago among others. Earthquakes of M 5.0 hit in the Dominican Republic on February 1, 2023 and June 14, 2021 but the last event in the area within about 200 km of today's epicenter occurred on September 23, 2018 with M 5.2 and an M 5.1 on January 23, 2012. At the time of the M 5.2 in September 23, 2018 this summary noted:
"An earthquake of M 5.2 also shook the Dominican Republic near local solar midnight today. NEIC reported it was felt with intensity V in Montellano, Jarabacoa, La Vega and IV in the Dominican Republic in Sabana Grande de Boya, Las Terrenas, Villa Vazquez, Sabaneta, Moncion, San Jose de las Matas, Villa Gonzalez, Palmar Arriva, Santiago, Sosua, Moca, Jamao al Norte, Mayaguez, Puerto Rico, Santo Domingo, El Carril, Nagua, Cotui, Bonao, San Francisco e Macoris, Tireo, Gaspar Hernandez, Saint-Raphael, Baitoa, Puerto Plata, Altimira, Luperon, Mao, and Villa Elisa. It was probably promoted by tidal stresses associated with the full moon which maximized near this hour. The last earthquake in the Dominican Republic within about 150 km of today's epicenter with M>=5.2 was an M 5.5 on January 5, 2012 and is the second strongest regional aftershock to date since January, 2010 when an M 7.0 killed hundreds of thousands in the area." (September 23, 2018)
The mainshock of M 5.0 occurred within minutes of local solar noon and may have been promoted by tidal stresses which maximize near this hour.
Forecast 158052 had expected today's event within about 50 km was likely
around November 12, 2023.

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

"The strongest earthquake in the world today was an M 6.7 in the Banda Sea of Indonesia. This event was also felt in northern Australia at Darwin. BMG reported the mainshock of M 7.1 was felt with intensity up to V in the Tanimbar Islands. BMG reported this activity in the Tanimbar region was felt with intensity IV in Bandaneira, III in Maluku Tengah, Banda, Maluku Tenggara, at Kecil, Manyeuw, Hoat Sorbay, in Tanimbar at Tanimbar Selatan, Selaru, Wer Tamrian, Wer Maktian; in Seram Bagian in Maluku Barat Daya and in Kota Tual and many other communities experienced lesser shaking. No tsunami was observed or expected with this event." (November 9, 2023)
Today's M 6.0 occurred within minutes of local solar noon and was probably
promoted by strong tidal stresses which predominate at this hour. Forecast 158000 had expected today's activity was likely around November 12.

An earthquake in Eastern New Guinea also occurred today in Eastern New Guinea, PNG. NEIC reported these earthquakes of M 5.4 and M 5.0 in New Guinea were felt with intensity up to V in the area(s) of New Guinea in Madang. EMSC reported moderate shaking in Madang, Papua New Guinea. This is probably an aftershock of an M 6.7 on October 7, 2023. At that time this was described in this summary as:
"The strongest earthquake in the world today was an M 6.9 in Papua New Guinea.
It was followed by an M 6.7 and several moderate events of M>=5. An M 5.1 aftershock was felt in Madang and Port Moresby, Papua New Guinea. Other events in the series were not initially given intensities by NEIC however some felt data comes from Madang, PNG. No tsunami was reported as this epicenter is inland near the coast." (October 7, 2023)
Forecast 158011 had expected today's event was likely within about 50 km around November 13.

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

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

The strongest earthquake in the U.S. or Canada today was an M 5.2 in the Mentone area of Texas. It was reported with intensity up to VI in Mentone, Texas and with moderate shaking in Carlsbad, New Mexico an in Fabens, El Paso, Texas among others.
This event was probably promoted by well injection of waters following fracking and extraction of oil and gas in the region. This may also have been promoted by geomagnetic effects associated with the current geomagnetic storm and/or by tidal stresses associated with the upcoming new moon as described in this issue in previous summaries as:
"The new moon will arrive on November 13, 2023 at 09:27 UT. Longitudes at local solar noon are near 37 East while those at local solar midnight are near 143 West longitude. These include Hawaii and areas of eastern Alaska and western Canada and to a lesser extent areas off the coast of Oregon and California while in the east they include Eastern Turkey where an M 7.7 hit on February 6, 2023 as well as Ethiopia and areas off southern Africa. These and surrounding areas are the most likely to see tidally enhanced seismicity at this time. A moderate to large aftershock is possible in Turkey at this time." (November 7-8, 2023)
A series of minor aftershocks followed the M 5.2 in western Texas today and continued throughout the day. The M 5.2 is the strongest earthquake in Texas since an M 5.4on December 16, 2022 about 200 km northeast of this epicenter and an M 5.4 on November 16, 2022 which began the sequence of events in this region of the Permian Basin of Texas. At the time this summary noted:
"The strongest earthquake in the U.S. or Canada today was an 5.3-5.4 in western Texas. NEIC reported it was felt with maximum intensity V in Texas at Barstow, and in Jal, New Mexico with intensity IV in Texas at Wink, Pecos, Salt Flat and III in Mentone, Loving, Pyote, Van horn among others. It was followed by an aftershock of M 4.1 in Western Texas. NEIC reported it was felt with maximum intensity V in Pecos, Texas and IV in Odessa, Texas. Lesser intensity of II-III was reported felt in New Mexico at Carlsbad, Eunice, Artesia, Hobbs and in Texas at Fort Davis, Coyanosa, Odessa, Fort Stockton, among others and may have been felt as far as Oklahoma. An M 3.8 aftershock was also felt in western Texas and New Mexico today. NEIC reported maximum intensity IV in El Paso, Texas with III in Canutillo, Texas and in New Mexico at Carlsbad and Lovington. The M 3.8 was preceded by a swarm of events of M 2.9, 3.5, 2.8... felt in the same area of Texas and New Mexico. The last earthquake within about 250 km of today's epicenter with magnitude greater than or equal to M 5.3 in Texas was an M 5.7 about 200 km to the southeast of today's epicenter (on April 14, 1995) . That was the only such regional earthquake in western Texas in at least 35 years." (November 17, 2022)
Forecast 157830 had expected today's event within about 50 km of this epicenter was likely around November 8. The mainshock parameters are listed below. A listing of events of M>=2 today can be found under the "ROCKY MOUNTAINS" section of this summary.

Several moderate earthquakes and a number of minor ones occurred today in the current series in Iceland. The largest of today's events were of M 4.5 and 4.6.
They were reported by EMSC to have been felt with moderate intensity in Iceland in the Reykjavik area at Grindavik, Reykjanesbaer, Reykjavik, Seltjarnarnes, These events were probably promoted by strong geomagnetic stresses associated with the current geomagnetic storm at high latitudes as noted in previous issues of this report:
"The geomagnetic field saw major storm conditions today. The AP level was 40. High latitudes saw major storm conditions with AP 51. Middle latitudes were at minor storm conditions with AP 27. This is the strongest global geomagnetic storm since AP reached 79 on April 24, 2023. It is likely to enhance global seismicity especially near the geomagnetic equator and at high latitudes beginning around November 8 and continuing for several days but will dampen seismicity in the short term.." (November 6-7, 2023)
Five events of M>=4.1 were reported today in this area. Most of this activity occurred within an hour of local solar midnight and may have been promoted by tidal stresses which maximize near this hour. There is a possibility that this will lead to larger events and/or a continuation of the eruption that began in 2021 after about 700 years of non-eruptive activity. Forecast 157925 had expected today's activity within about 100 km was likely around November 7.

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