The strongest earthquake reported by NEIC or EMSC today was an M 5.2 in the region of Fiji. This event may have been enhanced by Tropical cyclone Wasi as previously noted in this summary as:
"Tropical cyclone Wasi (18P) continued today in the area of Samoa with winds up to 50 kts. Stresses from this storm may enhance regional seismicity in Samoa and northern Tonga over the next four days with a moderate to strong regional quake possible in this time frame." (February 20-22, 2020)
This earthquake, like those in Eastern Europe and the Kuril Islands is located at 103 degrees from the M 7.7 south of Cuba of January 28. These are the only active seismic zones at this distance from that event and may continue to see enhanced seismicity in coming days.

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 STRONG EARTHQUAKE ON IRAN-TURKEY BORDER
EARTHQUAKE SUMMARY FOR FEBRUARY 23, 2020
The strongest earthquake in the world today was an M 6.0 on the Turkey-Iran border in eastern Turkey. It is a co-mainshock with the M 5.7 which hit the area yesterday. Today's event was reported by NEIC to have been felt with maximum intensity VII in Azerbaijan and Iran at Dilman; IV in Iran at Orumiyeh, Tebriz and II-II in Merand, Yerevan, Armenia, Arbil, Iraq and in Sarband and Tehran, Iran. When the M 5.7 occurred earlier this summary noted in the previous issue:
"The strongest earthquake in the world today was an M 5.7 in eastern Turkey near the Iran border. NEIC reported it was felt with intensity VII in Ozalp, Van, Turkey and in Iran at Khoi Azarbayenj-e, Gharbi and Orunmiyeh, Azarbaijan. This is the strongest earthquake in the region within about 200 km of this epicenter since an M 6.4 on August 11, 2012. Today's event was probably promoted by the new moon today as it occurred near local solar noon at the epicenter. Forecasts 122002 and 122219 had expected this activity within about 100 km was likely around February 21-24. This epicenter is located at 102 degrees from the M 7.7 south of Cuba of January 28, 2020 and was probably promoted by energy from that source." (February 22-23, 2020)
Following the earthquake in Cuba of January 28, 2020 this summary had noted that strong seismicity in the region of eastern Turkey and the Kuril Islands was likely as triggered seismicity as:
"The earthquake near Cuba may reset global seismicity as it is the strongest in nearly a year in the world. Far-field triggering is most likely in eastern Turkey, Iran/Iraq and the east African Rift valley as well as in Hokkaido and northern Japan (103 degrees)" (January 29, 2020; repeated following the M 7.0 in the Kuril Islands on February 13-14, 2020)
and
"A major earthquake of M 6.9-7.0 shook regions of the Kuril Islands today. NEIC reported maximum intensity V in Hokkaido and IV in Sakhalin, Russia. Intensity II-IV was reported from areas of Hokkaido within about 500 km of the epicenter.
This epicenter is at 102-103 degrees from the M 7.7 south of Cuba on January 28, and the first major quake in the world since that time. Seismic energy from large earthquakes concentrates at the surface around 102-103 degrees from the mainshock epicenter after reflection and refraction off inner earth boundaries." (February 13-14, 2020)
This area of Turkey-Iran border first became active on February 16, 2020 with an M 4.8 foreshock. The last earthquake within about 200 km of today's M 6.0 with equal or larger magnitude occurred on August 11, 2012 with M 6.3 and 6.4 about 200 km east of today's epicenter. The only other such event in the region in the past 30 years was an M 7.1-7.3 on October 23, 2011. Forecast 122219 had expected today's activity was likely around February 24. Today's activity is at 102-103 degrees from both the M 7.1 in Central California of July 6, 2019 and from the M 7.7 south of Cuba of January 28, 2020. It is also at the fifth node (72 degrees) from the M 7.0 in the Kuril Islands of February 13 and may have been promoted by energy from these events.

Moderate earthquakes of M 4.7 and M 4.8 also continued in western Turkey today.
NEIC reported this earthquake of M 4.6 in Western Turkey was felt with intensity II-III in the area(s) of Western Turkey at Izmir, Buyukorhan, Bursa and Mudanya. A smaller M 4.4 earlier in the day was felt with intensity IV in Akhisar and II in Izmir. These appear to be aftershocks of an M 5.6 at this epicenter on January 22, 2020. The last similar aftershock was an M 4.8 on February 18. Forecast 12221 had expected today's activity was likely around February 24.

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

MODERATELY STRONG QUAKE SHAKES EASTERN TURKEY-IRAN BORDER
EARTHQUAKE SUMMARY FOR FEBRUARY 22, 2020
The strongest earthquake in the world today was an M 5.7 in eastern Turkey near the Iran border. NEIC reported it was felt with intensity VII in Ozalp, Van, Turkey and in Iran at Khoi Azarbayenj-e, Gharbi and Orunmiyeh, Azarbaijan.
This is the strongest earthquake in the region within about 200 km of this epicenter since an M 6.4 on August 11, 2012. Today's event was probably promoted by the new moon today as it occurred near local solar noon at the epicenter. Forecasts 122002 and 122219 had expected this activity within about 100 km was likely around February 21-24. This epicenter is located at 102 degrees from the M 7.7 south of Cuba of January 28, 2020 and was probably promoted by energy from that source.

The strongest earthquake in the U.S. or Canada today was an M 4.3 off the coast of Northern California. NEIC reported it was felt with intensity II-III in California at Petrolia, Ferndale, Rio Dell, Fortuna, Eureka, Whitethorn, Carlotta, Myers Flat and Redway. This event may have been promoted by the new moon as it occurred within half an hour of local solar noon. The new moon arrived today as noted in previous issues of this summary:
"The New Moon will arrive on February 23, 2020 at 15:32 UT. Longitudes which are sub-solar at this time are near 52 West while those antisolar are at 128 East longitude. These include areas of the Central Atlantic such as Puerto Rico and the South Sandwich Islands in the west and central Indonesia, the Philippines and Japan in the east. A strong tidally enhanced earthquake is possible in the next six days. Other tidal enhancement would promote larger quakes near local solar noon and midnight. Many other areas of the earth can also see tidal enhancement of seismicity at this time." (February 21-22, 2020)
This event is the strongest within about 100 km of this epicenter since an M 5.2 on October 28, 2019 and prior to that an M 5.6 on June 23, 2019 in the regional activation of June and early July 2019. Forecast 122235 had expected today's event within about 25 km of this epicenter was likely around February 23. This epicenter is at the sixth node (60 degrees) from the M 7.0 in the Kuril Islands of February 13, 2020 and was probably promoted by energy from that epicente

A series of moderate earthquakes occurred today in the West Chile Rise. The largest of these as of M 5.5 and M 5.1. They were not reported felt in this remote area. The M 5.5 is the strongest within about 200 km of this epicenter since an M 5.9 on May 6, 2014. Forecast 122085 and 122312 had expected moderate activity southeast of these epicenters was likely around February 21-23. This activity is at 144 degrees from the M 6.8 of January 24, 2020 in eastern
Turkey and may have been enhanced by energy from that source. It is also at the sixth node (60 degrees) from the M 7.7 south of Cuba of January 28, 2020.

Seismicity was also up in the Southwest Pacific today where the second strongest earthquake of the day - an M 5.6 and 5.2 occurred in central Tonga. These were not reported felt in this area. They were probably enhanced or promoted by Tropical cyclone Wasi which was passing through the area at the time of these events. This had been expected in previous issues of this summary as:
"Tropical cyclone Wasi (18P) continued today in the area of Samoa with winds up to 50 kts. Stresses from this storm may enhance regional seismicity in Samoa and northern Tonga over the next four days with a moderate to strong regional quake possible in this time frame." (February 20-22, 2020)
The M 5.6 is the strongest earthquake within about 200 km of this epicenter in Tonga since an M 6.1 on June 15, 2019. Most activity at this magnitude level in the past three years has occurred north of today's epicenter. Forecast 122075 had expected today's event within about 50 km was likely around February 19. This activity is at 146 degrees from the M 6.8 of January 24, 2020 in eastern Turkey and may have been enhanced by energy from that source. Also, like the event in eastern Turkey today this activity is located at 102 degrees from the M 7.7 south of Cuba of January 28, 2020 and was probably promoted by energy from that source.

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 SEISMICITY IN SOUTHERN; BAJA CALIFORNIA
EARTHQUAKE SUMMARY FOR FEBRUARY 21, 2020
A light to moderate earthquake shook the valleys west of Los Angeles today. NEIC reported this event of M 3.5-3.9 was felt with intensity II-III in Castaic, Valencia, Santa Clarita, Stevenson Ranch, Canyon County, Lake Hughes, Newhall, Los Angeles, Northridge, San Fernando and in general within about 100 km of the epicenter.
This activity had been expected at this time as reported in the previous issue of this summary:
"The strongest earthquake felt in the U.S. or Canada outside Alaska today was an M 3.2-3.3 in the Ridgecrest area of Southern California. NEIC reported it was felt with intensity II-III in Ridgecrest and Wofford Heights, California.
Some evidence suggests that Southern California, and especially the valleys west of Los Angeles, may see enhanced seismicity at this time. When an M 6.0 in New Guinea at 103 degrees from Southern California occurred this summary suggested:
"The strongest earthquake in the world today was an M 6.0-6.1 in northern New Guinea. NEIC reported it was felt with intensity IV in Aberpura, Papua New Guinea, Indonesia. Strong earthquakes in this area can affect seismicity in the Los Angeles area of California as it is located at 103 degrees from this. Major quakes in New Guinea are often followed by moderate to strong quakes in southern California about a month later. Major quakes in California often occur in January and February (for example San Fernando - February 9, 1971 and Northridge - January 16, 1994). Today's event is not large enough to trigger this large an event but may be precursory to larger regional events in New Guinea." (January 19, 2020)
When an M 4.5 on the Kansas-Nebraska border followed the next day this summary followed up on this with:
"While this appears to be part of the general increased seismicity in Oklahoma and Kansas, the enhanced magnitude may indicate precursory activity to a moderate earthquake along the western edge of the North American plate in the next several weeks." (January 19-20, 2020)
The area of southern California where increased seismicity was expected saw a moderate M 4.6 on January 25 near Barstow and M 4.4 in the Mammoth Lakes region of Central on February 1, 2020, but to day the area of Los Angeles has been relatively quiet." (February 20-21, 2020)
The last earthquake within about 50 km of today's epicenter in western Los Angeles, California occurred more than five years ago on January 4, 2015 with M 4.2. An M 4.1 also occurred slightly west of this on March 12, 2016. Forecast 121983 had expected regional seismicity around February 18. This epicenter is located at 104 degrees from the M 6.8 in Turkey of January 24 and may have been promoted by energy from that source.

P: 18FEB2020 121983 33.9N 118.3W 2.5-4.3 BAAAA So. California
The activity in Southern California was joined by unusual quakes to the south in the area of Baja California. The strongest of these was an M 4.0 west of Baja California in a very unusual epicenter. The M 4.0 off the coast of Baja California is the strongest within about 100 km of that epicenter since an M 4.2 on July 8, 2014. Unusual events such as this can often signal unusual stresses which can lead to stronger regional events down the road. Forecast 121979 had expected an event to the east in mid-February. This activity is at the fifth node (72 degrees) from the M 7.0 in the Kuril Islands of February 13, 2020 and may have been promoted by energy from that event.

The strongest earthquake in the U.S. or Canada and in the world today was an M 5.2 in the active area of the western Andreanof Islands, Aleutians, Alaska. It was not reported felt in this remote region. This is the largest quake in the western Andreanof Islands since an M 5.4 event on January 28. That was an aftershock of event of M 6.2 and 6.1 on January 23 and 26. Forecasts 122031 had expected today's activity within about 50 km was likely in mid-February.

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.

M 5.9 SHAKES KAMCHATKA
EARTHQUAKE SUMMARY FOR FEBRUARY 20, 2020
The strongest seismicity in the world today continued at high latitudes and near the geomagnetic equator. This included events of M 5.9 in Kamchatka at high latitude and of M 5.4-5.5 in the Banda Sea, Indonesia and Mindanao, Philippines near the equator. This may be related to the geomagnetic storm of the past several days as noted in the previous issues of this summary:
"The geomagnetic field saw disturbed conditions today. The AP level was 14. High latitude geomagnetic field also saw minor storm conditions with AP at 36. Active conditions in the geomagnetic field are often accompanied by an upswing in global seismicity especially at high latitudes and near the geomagnetic equator." (February 18-29, 2020)
The largest earthquake in the world today occurred as an M 5.7-5.9 in Kamchatka. It may have been felt with intensity V in Mohovaja, Kamchatka. At M 5.9 this is the strongest earthquake within about 150 km of this epicenter in Kamchatka since an M 6.4 on March 20, 2016 and prior to that an M 6.6 on November 12, 2013. Forecast 122033 had expected today's event was likely in this area around February 20. This epicenter is at the fourth node (90 degrees) from the M 7.7 in Cuba of January 28 and may have been promoted by energy from that source.

The strongest earthquake in the U.S. or Canada today was an M 3.6 in Central Alaska. The last earthquake of M>=3.6 within about 100 km of today's epicenter was an M 3.7 on February 2, 2020 and prior to that an M 3.7 on January 14 and an M 3.9 on January 11. Forecast 122049 had expected activity in this area around February 19. NEIC reported this earthquake of M 3.3 in Central Alaska was felt with intensity II-III in the area(s) of Central Alaska at Fairbanks, Fort Wainwright, North Pole, Eielson, Delta Junction.

The strongest earthquake felt in the U.S. or Canada outside Alaska today was an M 3.2-3.3 in the Ridgecrest area of Southern California. NEIC reported it was felt with intensity II-III in Ridgecrest and Wofford Heights, California.
Some evidence suggests that Southern California, and especially the valleys west of Los Angeles, may see enhanced seismicity at this time. When an M 6.0 in New Guinea at 103 degrees from Southern California occurred this summary suggested:
"The strongest earthquake in the world today was an M 6.0-6.1 in northern New Guinea. NEIC reported it was felt with intensity IV in Aberpura, Papua New Guinea, Indonesia. Strong earthquakes in this area can affect seismicity in the Los Angeles area of California as it is located at 103 degrees from this. Major quakes in New Guinea are often followed by moderate to strong quakes in southern California about a month later. Major quakes in California often occur in January and February (for example San Fernando - February 9, 1971 and Northridge - January 16, 1994). Today's event is not large enough to trigger this large an event but may be precursory to larger regional events in New Guinea." (January 19, 2020)
When an M 4.5 on the Kansas-Nebraska border followed the next day this summary followed up on this with:
"While this appears to be part of the general increased seismicity in Oklahoma and Kansas, the enhanced magnitude may indicate precursory activity to a moderate earthquake along the western edge of the North American plate in the next several weeks." (January 19-20, 2020)
The area of southern California where increased seismicity was expected saw
a moderate M 4.6 on January 25 near Barstow and M 4.4 in the Mammoth Lakes region of Central on February 1, 2020, but to day the area of Los Angeles has been relatively quiet.

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

HIGH LATITUDE SEISMICITY CONTINUES WITH GEOMAGNETIC STORM
EARTHQUAKE SUMMARY FOR FEBRUARY 19, 2020
A series of earthquakes occurred at high latitudes today. These included an M 4.5 in the Arctic Ocean near Svalbard; an M 5.1 in the South Sandwich Islands of the South Atlantic and an M 5.0 in the Bouvet Island region of the South Atlantic. The occurrence of these events at this time may be related to the strong geomagnetic storm at high latitudes which continued today and was reported on in this summary in the previous issue as:
"The geomagnetic field saw disturbed conditions today. The AP level was 14. High latitude geomagnetic field also saw minor storm conditions with AP at 36. Active conditions in the geomagnetic field are often accompanied by an upswing in global seismicity especially at high latitudes and near the geomagnetic equator." (February 18-29, 2020)
They follow an unusual M 5.5 in the Arctic Ocean yesterday which was the strongest in that region in the past 18 years as noted at the time:
"Today's event is the strongest within about 400 km of today's event in the Arctic Ocean since an M 5.4-5.6 on May 3, 2002, the only other such event in the are in the past 30 years." (February 18-19, 2020)
Today's event in the Bouvet Island region is the strongest since an M 5.6 on January 12, 2020 and an M 5.1-5.4 on November 17, 2019. It is antipodal to the recent activity in the central Andreanof Islands at 175 West longitude. This activity began with an M 6.4 on November 24, 2019 and has been followed by the most recent aftershock of M 5.0 on February 13, 2020. The Bouvet Island quake had been expected in forecast 122093 within about 150 km of today's epicenter to occur around February 21.

The South Sandwich Islands saw seismic events of M 6.1 on February 8 and January 20 but both of these were about 250 km south of today's epicenter. The last such event with M>=5.1 in the area within about 150 km of this epicenter occurred on June 24, 2019 with M 5.5. Forecast 122095 had expected today's earthquake within about 50 km was likely around February 20. This epicenter is near the antipode of the M 7.0 in the Kuril Islands of February 13, 2020.

The strongest earthquake in the U.S. or Canada today was an M 4.5 off the coast of Oregon. NEIC reported this earthquake was felt with intensity II-III along the coast of Oregon at Bandon, Coos Bay, Brookings, Eugene, Portland and Bend.
This follows a similar M 4.7 on February 8, 2020 about 150 km southeast of this and M 5.9 near this epicenter on September 5, 2019. Forecast 122020 had expected today's event was likely within about 75 km of the epicenter around February 16. Other regional activity accompanied this event in the Vancouver and Queen Charlotte Island region of British Columbia with M 3.0 and 2.6.

An unusual earthquake of M 3.7-3.9 shook areas of central and northern France in Brittany today. NEIC reported maximum intensity IV in Landeda, Bretagne, France and II-III in Bretagne at Landemeau, Brest, Bohars, Plouzane and Saint-Pabu. This is the strongest earthquake in the Brittany area within about 100 km of this epicenter since an M 3.9 on April 28, 2016 about 50 km northwest of today's epicenter. No events of M>3.9 have occurred in the area in the past 30 years.
Forecast 122044 had expected today's event was likely around February 21.

An unusual quake also shook areas of western Texas today. NEIC reported intensity IV in Texas at Gardendale, Midland and Odessa and II-III in Andrews, Texas. Today's event is the first of M>=3.3 in western Texas within about 100 km of this epicenter in more than 30 years. Prior activity about 200 km northeast of this occurred between 2008 and 2019 and may have been related oil mining in the area. Other activity recently in western Texas has concentrated to the west near 103.5 and 104.5 West longitude.

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

GEOMAGNETIC STORM COINCIDES WITH HIGH LATITUDE SEISMICITY
EARTHQUAKE SUMMARY FOR FEBRUARY 18, 2020
The strongest earthquake in the world today was an M 5.4 in the Arctic Ocean north of Svalbard. It was not reported felt in this remote area. It occurred as a strong geomagnetic storm was beginning at high latitudes as described in this summary:
"The geomagnetic field saw disturbed conditions today. The AP level was 14. High latitude geomagnetic field also saw minor storm conditions with AP at 36. Active conditions in the geomagnetic field are often accompanied by an upswing in global seismicity especially at high latitudes and near the geomagnetic equator." (February 18-29, 2020)
Today's event is the strongest within about 400 km of today's event in the Arctic Ocean since an M 5.4-5.6 on May 3, 2002, the only other such event in the area in the past 30 years. Forecasts 121832 abnd 122056 had expected regional seismicity in mid-February. This epicenter is at the fifth node (72 degrees) from the M 7.7 south of Cuba of January 28 and may have promoted by energy from that source.

A moderate earthquake of M 4.6 shook regions of eastern China in Shandong.
This is the strongest earthquake within about 250 km of this epicenter since events of M 4.6 on February 12, 2018 and January 23, 2013. The last earthquake in the region of significantly larger magnitude was an M 5.1 on September 20, 1995 and M 5.0 on January 28, 1991. Forecast 121990 had expected in this area of China was likely around February 18.

A pair of moderate earthquakes of M 4.3 and 4.8 also shook the area of western Turkey south of Istanbul. NEIC reported this earthquake of M 4.8 in Western Turkey was felt with intensity II-III in the area(s) of Western Turkey in Balikesir (IV) and Izmir, Foca, Bursa, Mudanya, Istanbul. The last earthquake of M>=4.8 within about 250 km of this epicenter was an M 4.9 on February 4. These appear to be aftershocks of an M 5.6 on January 22, 2020 and continue regional activation which began in late 2019. Forecast 121994 had expected today's event within about 150 km of this epicenter was likely around February 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.

MODERATE EARTHQUAKE IN BONIN ISLANDS, JAPAN
EARTHQUAKE SUMMARY FOR FEBRUARY 17, 2020
A moderate earthquake of M 5.4 occurred today south of Honshu in the Bonin Islands, Japan. It was not reported felt in this remote area. This area can generate large earthquakes but has been relatively quiet in recent years. The last event within about 200 km of today's epicenter was an M 5.4 on December 25, 2018. The last event of larger magnitude in the area was an M 5.7 on December 21, 2017. The current lull in regional seismicity may be due to stress release with the M 7.8 south of this on May 30, 2015. Forecast 121934 had expected today's activity in the Bonin Islands around February 20.

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

MODERATELY STRONG QUAKE SHAKES SOUTHERN IRAN
EARTHQUAKE SUMMARY FOR FEBRUARY 16, 2020
The strongest earthquake in the world today was an M 5.5 in southern Iran. NEIC reported it was felt with maximum intensity IV in Iran at Gheshm and Bandar Abbas. It was also felt with intensity II-IV in the United Arab Emerates at Umm, Ras Al Khaimah, Ujman, Ash-Shariqah, Khawi, Dubai. An M 4.6 foreshock preceded it by about 6 minutes. This is the strongest earthquake in southern Iran within about 200 km of this epicenter since a similar M 5.5 about 150 km north of this on January 22, 2016 but the last of significantly larger magnitude in the area was an M 6.1 on May 1, 2013. Forecast 121944 had expected today's earthquake was likely in this area around February 18. This epicenter is at the fifth node (72 degrees) from the M 7.0 in the Kuril Islands of February 13 and may have been promoted by energy from this source. Other moderate quakes at the fifth node from the Kuril Islands included a moderate M 4.8 in eastern Turkey and several events including an M 3.3 in Baja California.

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.
