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.

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.

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 48^th 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.

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.
