MODERATE SWARM OFF NORTHERN CALIFORNIA

 

EARTHQUAKE SUMMARY FOR OCTOBER 17, 2017

 

A series of light earthquakes off the coast of Northern California today culminated late in the day with an M 4.2 event.  NEIC reported this earthquake of M 4.2 off the coast of Northern California was felt with intensity II-III in the area(s) of Eureka, California. The last earthquake of M>=4.2 within about 100 km of these epicenters occurred on March 27, 2017 with M 4.2 but the last of larger size was an M 4.6 and 5.0 on September 25, 2016. A moderately large earthquake of M 5.7 hit about 100 km southeast of today's epicenters on September 22, 2017 and this may be regional aftershock activity from that event. October 18 is a high point in the annual seismicity of California and another moderate earthquake in the region is possible in the next several days. This activity is at 148 degree from the Bouvet Island quake of M 6.7 of October 10 and may have been promoted from that source. Forecast 111363 had expected a moderate quake was possible in this region around October 14.

On the opposite side of North America a triplet of light earthquakes of M 2.1-2.4 shook New York, Quebec and New Hampshire. These are not unusual events but three in a day at three different epicenters is unusual. These were not reported felt in their respective epicentral areas. Forecasts 111355 and 111358 expected this activity in mid-October.  This activity is at 120 degrees (node 3) from the Bouvet Island quake of M 6.7 of October 10 and may have been promoted from that source.

A series of light earthquakes along the path of Hurricane Ophelia in western Europe and the Atlantic Ocean marked the dissipation of that storm. These

occurred in the Azores, Iceland and France. Four earthquakes of M>=3 in France were unusual. Only one earthquake of M>=3.3 has been recorded in northwestern France to date during 2017 - an M 4.1 on July 1, 2017. Other effects from Ophelia included the fanning of deadly fires in Portugal and Spain. More than 60 deaths have been attributed to the Portugal fires, the worst fire season on record.  The activity in Europe had been expected in this summary as:

 

 

"Hurricane Ophelia continued in the North Atlantic with winds up to 115 kts. It is expected to continue as a hurricane and to track west into the Azores and Europe over the next several days. Seismicity in France, Spain and Portugal will probably increase as Ophelia approaches that region. It is then expected to turn to the north reaching Ireland and Scotland around October 18 where minor seismic

events could be triggered by stresses from this unusual hurricane." (October 15, 2017)

 

Much of this activity is occurring at 100-102 degrees from the Bouvet Island quake of October 10 and may be promoted from that source. Seismic energy from large earthquake concentrates on the surface in this distance range.

The strongest earthquakes in the world today again occurred in the Tonga region. These included the only events of M>=5 - an M 5.3 and 5.1. They were not reported felt. Forecasts 111428, 111440 and 111441 had expected this activity in mid-October.

 

Like the activity in France and the Azores, much of this activity is occurring at 100-102 degrees from the Bouvet Island quake of October 10 and may be promoted from that source. Seismic energy from large earthquakes concentrates on the surface in this distance range.

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.
