GEOMAGNETIC STORM MAY HAVE TRIGGERED SERIES  NEAR VANCOUVER AND KURILS

 

EARTHQUAKE SUMMARY FOR FEBRUARY 13, 2019

 

A new geomagnetic storm occurred today beginning about 0700 UT and was accompanied by a series of moderate earthquake in the high latitudes of the Kuril Islands (M 5.0, 5.0, 5.1, 4.5) and in the region of Vancouver Island, British Columbia, Canada (M 3.6, 3.4, 3.2, 4.1, 5.1). Other locations at high latitudes showing moderate seismicity during this short-lived storm included the South Sandwich Islands (M 4.9, 4.9); Kamchatka (M 5.2) and the Rat Islands, Aleutians (M 4.8). A swarm in the northern Gulf of California also coincided with the start of this geomagnetic storm with magnitudes up to M 4.1. All of these were probably promoted by effects from the geomagnetic storm. The geomagnetic storm is described in this summary as:

 

"The geomagnetic field saw disturbed conditions today. The AP level was 13. High latitude geomagnetic field saw active conditions  with AP at 28. This may be the beginning of a new geomagnetic storm but more likely it is a short excursion which peaked around 1200-1500 UT on February 13. Seismicity along the geomagnetic equator may be slightly enhanced but is more likely to be promoted at high latitudes. The storm began about 0700 UT and was immediately followed by a series of light to moderate earthquake in the Vancouver Island area of B.C. Canada which was near local solar midnight at the time of maximum KP. KP at high  latitudes reached 6 between 0700 and 1400 UT. The only other time high latitude KP has reached level 6 in the past month was during the storm of February 1" (February 13-14, 2019)

 

The swarm in the Kuril Islands northeast of Hokkaido, Japan was unusual and began as the geomagnetic storm was reaching maximum Kp. It included events of M 5.1, 5.0, 5.0 and 4.5. These were not reported felt in the epicentral area.

The Kuril Islands have been relatively quiet in recent months. The last event within about 300 km of today's epicenter with greater magnitude than M 5.1 was an M 5.8 nearly a year ago on March 7, 2018. The last of M 5.1 occurred on December 28, 2018. Forecast 113579 had expected today's activity within about 50 km of these epicenters was likely around February 12.

The earthquake swarm in the Vancouver Island, region of Canada began at 0715 with an N 3,2 as the geomagnetic storm was reaching towards maximum and included an M 3.4, 3.5, 4.1 and 4.8-5.1. These events were lightly felt in the epicentral area according to Earthquakes Canada. Earthquakes Canada reported the largest of these at M 5.1. The last earthquake within about 100 km of these epicenters off Vancouver with M>=5.1 in the NEIC database was an M 5.3 more than two years ago on January 7, 2017. Forecast 113591 had expected today's event within about 10 km of the epicenter was likely around February 13.

While not at high latitudes a swarm of light to moderate earthquakes also  occurred in the Gulf of California at the start of the geomagnetic storm and was probably promoted by it. These events of M 3.7, 3.8, 3.9 and 4.1 were the first of this size to be intimately associated with the geomagnetic storm. They occurred within minutes of local solar midnight, a prime time for geomagnetic effects. The last events within about 100 km of this epicenter with M>=4.1 occurred nearly two years ago on May 23, 2017 (M 4.3) and prior to that as an M 4.1 on January 18, 2017. Forecast 113474 had expected this activity within about 25 km was likely around February 17. This area is antipodal to Tropical Cyclone Gelena currently east of Madagascar. This summary had expected some seismic enhancement in the Gulf of California at this time due to focusing of seismic energy at the antipode of TC Gelena as:

 

 

 

"TC Gelena (13S) continued today east of Madagascar with winds up to 065 kts. It is expected to track to the southeast over the next week. The antipodal region at 26N 107W is antipodal to the Western Mexico and the Gulf of California.  Antipodal triggering may occur in the region of the Gulf of California and Baja, California."

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.

EARTHQUAKE SUMMARY FOR FEBRUARY 12, 2019

 

The strongest earthquake in the world today was n M 5.9 in the Northern Mariana Islands. NEIC reported it was felt with intensity II-III in Tinian, Marianas and Tamuning, Guam. No damage or tsunami was expected nor reported. This is the strongest earthquake in the Northern Mariana Islands within about 100 km of this epicenter since an M 7.7 about 75 km south of today's epicenter on July 29, 2016. Forecast 113462 had expected today's event in the Northern Marianas was likely Around February 15.

The second largest earthquake today was an M 5.1-5.2 in central Vanuatu.  This may have been promoted by Tropical Cyclone Oma which was over the epicenter when the earthquake occurred. This triggering had been expected in previous issues of this report as:

 

 

"TC 15P formed today in the region of northern Vanuatu with winds up to 45 kts. It is expected to track to the southeast over the next several days. Seismic enhancement in the region of Vanuatu could accompany the passage of this storm through the area." (February 11-12. 2019)

 

The last earthquake of M>=5.1 within about 100 km of this epicenter occurred with M 5.1 on November 19, 2018. The last of larger magnitude was an M 5.3 on September 17, 2018. Forecast 113644 had expected this event within about 15 km of the epicenter was likely around February 14.

The elevated seismicity along the North Anatolian Fault zone in Turkey to Greece continued today with an M 4.8 and aftershocks of M 4.2 in Central Turkey east of Istanbul. A strong earthquake in the Istanbul area is expected in the near term by many geophysicists and is apparently overdue. The recent activity along the North Anatolian Fault including today's event may be preparatory seismicity to such and event. The last event of M>=4.8 within about 150 km of this epicenter in Central Turkey occurred  more than three years ago on January 10, 2016 (M 4.9) and prior to that an M 5.0 on November 24, 2013. A major M 7.3 event occurred in this area on November 12, 1999 following the great quake in Izmit, Turkey in August, 1999. Forecast 113565 had expected this event was likely within about 50 km of the epicenter around February 13.

 

NEIC reported this earthquake of M 4.8 in northern Turkey was felt with intensity IV in Kizilcahamam, Ankara, and II-III in Incesu, Kayseri, Turkey.

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.

ANOTHER QUIET DAY INCLUDES UNUSUAL M 4.8 IN BAY OF BENGAL

 

EARTHQUAKE SUMMARY FOR FEBRUARY 11, 2019

 

Global seismicity remained at very quiet levels today. No earthquakes of M>5 were recorded. a rarity in global seismicity. An unusual quake in the Bay of Bengal, India was the largest recorded within about 250 km of that epicenter in at least 30 years.

 

An unusual event of M 4.9 occurred in the Bay of Bengal east of India today. NEIC reported this earthquake of M 4.9 in the Bay of Bengal was felt with intensity IV in Chetpet, Tamil Nadu, India and II-III in the area(s) of Tamil Nadu, India at Tinuverkadu, Saint Thomas, Ambattur, Manapakkam, Alandur, Madras and Anakaputhur, India.  This is the strongest earthquake recorded within about 300 km of this epicenter in at least 30 years. The only other event recorded in this area since 1990 with M>=4.0 was an M 4.8 on December 9, 1995.  Forecast 113168 had expected moderate activity southeast of this in early February.

The strongest earthquake of the day was an M 5.0 in the region of Samoa. This

occurred following the passage of Tropical Cyclone Neil through the region as noted in previous issues:

 

 

"TC Neil formed today in the region of Tonga with winds up to 45 kts. It is expected to track to the southeast over the next several days. Seismic enhancement in the region of Tonga and Fiji could accompany the passage of this ttorm through the area." (February 10-11, 2019)

 

Forecast 113641 had expected this event was likely in mid-February.

The strongest earthquake in the U.S. or Canada today was an M 4.1 off the coast of Oregon. This event had been expected in this summary to occur at this time in forecast 113570 within about 50 km of this epicenter. It appears to be part of the recent activation of seismicity off the northwest U.S. Earthquakes of larger or equal magnitude last occurred within about 100 km of this epicenter on January 27, 2019 (M 4.5) and July 29, 2018 (M 5.3, 4.4).

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

QUIET GLOBAL SEISMICITY CONTINUES

 

EARTHQUAKE SUMMARY FOR FEBRUARY 10, 2019

 

Global seismicity continued today at quiet levels. As with the past two days, the largest earthquake in the world today were M 5.0-5.3 and occurred in Southern Iran (M 5.3); Nicaragua/Honduras (M 5.3); Tonga (M 5.1) and Mindanao, Philippines (M 5.2). None of these earthquakes caused reported damage or casualties and most of this activity occurred in area which have been active over the past week.

 

The last earthquake in southern Iran of M>=5.3 within about 200 km of today's epicenter was an M 5.4 on July 22, 2018. The last of significantly larger magnitude was an M 6.1 on May 11, 2013. Forecast 113209 had expected today's event in Southern Iran was likely within about 150 km of the epicenter in early February. NEIC reported this earthquake of M 5.3 in Southern Iran was felt with intensity V in Bandar Abbas, Iran and II-III in the area(s) of Gheshm, Iran; Hasab, Oman; and in the United Arab Emirates at Abu Dhabi (IV) and II-III in Ras Al Khaiman, Ulman, Ash-Shanqaj.

OTHER GLOBAL EARTHQUAKE ACTIVITY

 

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

GLOBAL SEISMICITY REDUCED

 

EARTHQUAKE SUMMARY FOR FEBRUARY 9, 2019

 

As geomagnetic and tidal effects on seismicity diminished today, global seismicity was also reduced. The strongest earthquakes of the day were of M 5.0-5.2 and occurred in areas where activity has been strong over the past week. These include the Molucca/Halmahera area of Indonesia (M 5.2); northern Chile (M 5.1); Northern Mindanao, Philippines (M 5.2); and the Myanmar-India border (M 5.2).  None of these were damaging but most were felt in their respective epicentral areas. Tropical Cyclone Neil formed in the Tonga/Fiji region where events of M 4.8 and 4.9 occurred today. This storm could encourage elevated seismicity in the Tonga/Fiji region over the next several days.

 

The strongest earthquake in the U.S. or Canada today was an M 4.5 in the Near Islands, Aleutians, Alaska. It was not reported felt in the epicentral area. The last earthquake in the Near Islands within about 200 km of this epicenter with M>=4.5 occurred on October 26, 2018 with M 4.5-4.6 and prior to that on July 10, 2018 also with M 4.6. The last such event in the area with significantly larger magnitude than M 4.5 was an M 5.1 on August 8, 2017. Forecast 11332 had expected a moderate event in this region around February 5.

An outer-rise earthquake of M 3.6 occurred south of the Aleutians in the Fox Islands area today. Outer-rise events can be indicator of stress down slope in the subduction zone and have been used to identify area which may see a large to major upcoming earthquake. Forecast 113321 had expected activity in this area was likely around February 10.

Seismicity in California today continued at quiet levels. Today was the 48th anniversary of the M 6.7 San Fernando, California earthquake of 1971. The pattern in the area today included events south of Los Angeles, in the Channel Islands and west in the valleys which are similar to precursory activity in the region in February, 1971 and before the Northridge earthquake of January 1994. As earthquakes of M>6 in  the area tend to recur in 20-25 year cycles, it is possible that another significant earthquake in the area is near. Factors which could increase this probability include cyclones in the region east of Madagascar, strong geomagnetic or solar storms,  and strong tidal effects among others.

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 3.7 in the Fox Islands, Aleutians, Alaska. It was not reported felt in this remote area. An aftershock of M 3.3 followed about 3.5 hours later. A similar M 3.8 hit the same epicenter on February 7. Forecast 113317 had expected activity in this area in early February.

Seismicity in California was active in the M 2-3 range today but no events of M>=3 occurred and the swarms in the Landers area and the moderate quake in the northern coastal area discontinued. This may be due to lessening tidal stresses and/or the conclusion of the geomagnetic storm which appear to have helped promote this regional activation.

 

The most unusual earthquake in the U.S. or Canada was an M 3.1 in Ontario, Canada. NEIC reported this earthquake of M 3.1 in Ontario, Canada was felt with intensity II-III in the area(s) of Sudbury, Ontario, Canada.  This is the strongest event within about 100 km of this epicenter since an M 3.1 on September 30, 2015 more than three years ago. The last of larger magnitude

in this area was an M 3.8 on August 5, 2014. Forecast 113047 had expected this event was likely within about 50 km of the epicenter at the end of January or early 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.

STRONG SWARM EAST OF LOS ANGELES, CALIFORNIA; MODERATE QUAKE SOUTH OF HAWAII

 

EARTHQUAKE SUMMARY FOR FEBRUARY 7, 2019

 

An earthquake of M 4.0 in the area of Southern California near Ludlow east of Los Angeles  was widely felt today. It was followed by a series of lightly felt aftershocks. Several light foreshocks including an M 3.2 also occurred. NEIC reported the mainshock was felt lightly with intensity II-II in Ludlow, Newberry Springs, Joshua Tree, Yucca Valley, Twentynine Palms, Apple Valley, Indian Wells, La Quinto, Ontario and in general within about 100 km of the epicenter. This is the strongest earthquake in this region within about 75 km of this epicenter since February 23, 2016 and February 20, 2016 with M 4.1 and 4.3 respectively. A major earthquake of M 7.3 hit this area near Lander, California on June 28, 1992. Forecast 113259 had expected this activity was likely around February 7. This summary had anticipated regional seismicity would be enhanced at this time as:

 

"The area of Southern California, especially in the area east of Los Angeles ...

Seismicity in the Los Angeles area often increases in January and February. This includes the Northridge quake of  January 16, 1994 (M 6.7) and the San Fernando earthquake of February 9, 1971 (M 6.7). The time for stress to build up in the area may be about 23-25 years, consistent with the possibility of another such event on the horizon. This summary has noted this relation in the past. The Northridge event was preceded by a series of light earthquake south and west of Los Angeles not unlike the series which is now occurring. These may precede a moderate earthquake in the area." (January 31, 2019; February 6-7, 2019)

The largest earthquake in the world today was an M 5.4 in the Southwest Indian Ridge. It was not reported felt in the epicentral area. This epicenter is nearly antipodal to the earthquake in Southern California. Seismic energy from this may change the nature of the swarm in Southern California with the potential to enhance larger events in the region. The last earthquake on the Southwest Indian Ridge within about 200 km of this epicenter with M>=5.4 occurred on July 10, 2018 with M 5.6 and prior to that on July 12, 2016 (M 5.4). Only one event in the area has exceeded M 6.0 in the past 20 years  - an M 6.1 on August 17, 2013.    Forecast 113391 had expected today's event within about 25 km was likely around February 6.

An earthquake of M 5.4 also occurred in the Molucca and Halmahera, Indonesia region. This continues strong, expected activation of the region associated with the new moon. This had been discussed in the previous issue of this summary as:

 

 

"Strong earthquakes which occurred at the time of the previous new moon on January 6 included an M 5.8 in the Andreanof Islands, Alaska; an M 6.8 deep beneath Brazil; an M 6.6 in the Molucca area of Indonesia and an M 6.3 in Kyushu, Japan. These areas may see additional moderate to strong seismicity at this time." (February 1-6, 2019)

 

The last earthquake within about 200 km of this epicenter with M>-5.7 occurred on January 6, 2019 with M 6.6 and prior to that on April 15, 2018 (M 5.9). Today's event is probably an aftershock of the January, 2019." (February 6-7, 2019)

 

Forecast 113139 had anticipated today's activity was likely within about 50 km around February 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.

MODERATELY STRONG SEISMICITY CONTINUES ALONG GEOMAGNETIC EQUATOR

 

EARTHQUAKE SUMMARY FOR FEBRUARY 6, 2019

 

A series of moderately strong quakes hit along the geomagnetic equator in the Southwest Pacific today and in South America in northern Chile (M 5.3). These included an M 5.4 in the Central Philippines; M 5.7 in the Molucca Sea; an M 5.7 in Sulawesi and an M 5.5 in the Solomon Islands. As noted in previous issues of this summary, this was activity expected to be related to the recent geomagnetic storm and the new moon tides as:

 

 

"The new moon will arrive on February 4, 2019 at 21:04 UT. Longitudes which  are sub-lunar at this time are near 45 East and those which are sub-solar at near 135 West longitude. These are the zones which will experience maximum tidal stresses at this time. In the west they include western North America and Eastern Alaska and in the east, the Middle East and eastern Africa." (February 1-5, 2019)

 

and

 

"This is the strongest geomagnetic storm in more than a month (especially at high latitudes) since AP reached 24 on  December 28, 2018. Seismicity is expected to increase with a possible strong event near the geomagnetic equator and at high latitudes over the next three days as geomagnetic effects and the new moon promote fault slippage." (February 1-4, 2019)

 

Moderately strong earthquakes hit the region of Indonesia in the Molucca and Sulawesi areas. NEIC reported an M 5.7 was felt with intensity IV in Bitung and II in Manado, Sulawesi, Indonesia. BMG reported it was felt with intensity III-IV in Manado, Minahasa, Bitung, Ternate and Minahasa, Molucca, Indonesia. The last earthquake within about 200 km of this epicenter with M>-5.7 occurred on January 6, 2019 with M 6.6 and prior to that on April 15, 2018 (M 5.9). Today's event is probably an aftershock of the January, 2019 event as suggested in  earlier issues of this report:

 

"Strong earthquakes which occurred at the time of the previous new moon on January 6 included an M 5.8 in the Andreanof Islands, Alaska; an M 6.8 deep beneath Brazil; an M 6.6 in the Molucca area of Indonesia and an M 6.3 in Kyushu, Japan. These areas may see additional moderate to strong seismicity at this time." (February 1-6, 2019)

 

 

Forecast 113138 had expected this area to be active around February 8.

An earthquake of M 5.5 also hit the Solomon Islands where it was reported with intensity II-III in Buala, Isabel and Honiara, Guadalcanal, Solomon Islands. This epicenter is located within about 5 degrees of the local geomagnetic equator. The last earthquake within about 200 km of this epicenter with M>=5.5 was an M 6.0 on March 19, 2017. Forecast 113355 had expected a moderate earthquake in this area was likely in early February.

The M 5.3 in northern Chile was reported by NEIC to have been felt with intensity IV in Iquique and II in Arica, Tarapaca, Chile. CSN reported this earthquake was felt with intensity  III in  Tarapaca at Alto Hospicio, Huara, Iquique, La Tirana and II in Pica and in Arica and Parinacota at Arica with intensity III. NEIC reported these earthquake of M 4.5 and 4.2 in Northern Chile were felt with intensity II-III in the area(s) of Iquique, Tarapaca, Chile.  Moderate aftershocks were felt in the same area. This epicenter lies about 5 degrees south of the local geomagnetic equator. The last event in Tarapaca within about 150 km of this epicenter with M>=5.2 occurred on April 5, 2018 with M 5.6.An M 6.2 occurred about 200 km to the northeast on November 1, 2018.

Forecast 113379 had expected today's event was likely within this area around February 6. These earthquakes are located at 103 degrees from the M 7.1 near Anchorage, Alaska of November 30, 2018 and may have been promoted by energy from that source.

PHI reported it was felt with intensity V in Villasis, Pangasinan; IV in Baguio City and II in Subic, Zambales, Pasay City, Manila City, Mandaluyong City and Quezon City, Philippines. The last earthquake within about 200 km of this epicenter with M>=5.4 occurred on July 3, 2018 also with M 5.4 and prior to that on June 17, 2018 with M 5.4. The last of larger magnitud was an M 5.7 on October 2, 2016.  Forecasts 113180 and 113181 had expected this activity was likely around February 5-6.

The strongest earthquake in the U.S. or Canada today was an M 4.4 in Northern California. This is the latest in a series of events which are migrating from west to east and included an M 4.5 earthquake and aftershocks off the coast of Northern California and an unusual series on the coast. Today's event was reported with  maximum intensity IV in Willow Creek, California and moderate shaking in California at Blue Lake, Korbel, Arcata, Bayside, McKinleyville, Salyer, Eureka and Samoa, California among others within about 100 km of this epicenter.

 

This is the strongest earthquake in Northern California within about 50 km of this epicenter since an M 4.5 on August 28, 2015, an aftershock of an M 4.7 of July 21, 2106. A moderate earthquake of M 5.6 hit about 50 km to the north of today's epicenter on February 13, 2012. Forecast 113224 had expected a moderate earthquake was possible in this area in early February. This had been emphasized in earlier issues of this summary as:

 

 

"The area of California saw increasing seismicity today after several days of relative quiet. Light earthquakes occurred near Los Angeles and San Francisco with M 2.8. The M 2.8 in the San Francisco Bay area was followed by an M 2.2. These epicenters are located off the coast of San Francisco. Light to moderate earthquake in this area occasionally are followed by stronger events in the land area near San Francisco. One of the more interesting of these occurred on April 11, 1906 and followed a major earthquake in the Gulf of California of M 7.5 on April 10, 1906. These preceded the great M 8.3 quake in San Francisco on April 18, 1906. Further activity with a possible moderate event is likely in this area in the next week to ten days. A major solar or geomagnetic storm or the full moon of February 4, 2019. This tidal event is strongest in the area of California maximizing at 21:04 UT - near local solar noon and could trigger enhanced activity in California at that time. A further promoter of seismicity  in this area at this time is the M 7.1 in Mindanao, Philippines of December 29, 2018. This epicenter is located at 103 degrees from Central California, a distance at which triggering is likely from concentrated energy from Mindanao." (January 31, 2019).

 

This event is located at 101 degrees from the Molucca Sea M 7.0 of December 29, 2018 and was probably enhanced by concentrated seismic energy from that source.

 

The area of Southern California, especially in the area east of Los Angeles was also noted at the time as being subject to moderate seismicity at this time as:

 

"Seismicity in the Los Angeles area often increases in January and February. This includes the Northridge quake of  January 16, 1994 (M 6.7) and the San Fernando earthquake of February 9, 1971 (M 6.7). The time for stress to build up in the area may be about 23-25 years, consistent with the possibility of another such event on the horizon. This summary has noted this relation in the past. The Northridge event was preceded by a series of light earthquake south and west of Los Angeles not unlike the series which is now occurring. These may precede a moderate earthquake in the area." (January 31, 2019)

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.
