STRONG, DEEP FOCUS AFTERSHOCK STRIKES BENEATH FIJI

 

EARTHQUAKE SUMMARY FOR NOVEMBER 18, 2018

 

A strong earthquake of M 6.6-6.7 hit at a deep hypocenter today beneath Fiji. This is an  aftershock of the M 8.2 which struck the area on August 19, 2018. Due to the depth at about 533 km today's event did no damage at the surface and was not reported felt. No tsunami was generated from this deep earthquake. The last earthquake within about 200 km of this epicenter in Fiji occurred on September 30, 2018 (M 6.6) and the M 8.2 of August 19, 2018.  Forecast 121397 had expected this event within about 100 km was likely around November 18.

A series of moderate earthquakes also occurred on Ocean Ridges today. These regions often see a delayed response to strong geomagnetic storms.  Two of these occurred in the Svalbard region north of Norway with M 4.4. An event in the region occurred within minutes of local solar noon and was probably promoted by tidal stresses which maximize at this hour. Forecast 121380 had expected this activity was likely around November 21.

A set of earthquakes also occurred in the northern Mid-Atlantic with M 5.0 and 4.7. Theses events were not reported felt in this remote areas. The M 5.0 off the northern African coast was the strongest within about 200 km of this epicenter since an M      5.1 on January 26, 2018 and prior to that an M 5.7 on October 20, 2016. Forecast 121229 had expected this event was likely within about 100 km of the epicenter around November 20.

The northern event of this set occurred aas an M 4.7 south of the Reykjanes Ridge in the North Atlantic Ocean. It is the largest within aboug 200 km of this epicenter since an M 4.7 on November 7, 2018 and prior to that as an M 5.1 on August 14, 2017. Forecast 121359 had expected this event was likely around November 18 within about 100 km of this epicenter.

Two other ocean ridge events occurred east of Africa in the Mayotte region and  in the Red Sea. Both of these had magnitude M 4.5. Mayotte has been active in recent months but seismicity in the area has been on the decline in recent weeks. The last earthquake of M>=4.5 in this area occurred on November 7, 2018.  Similar events occurred October 16 and October 7, 2018. The Moyotte activity began shortly after the Hawaiian eruption this spring which are nearly antipodal to Mayotte, Energy from Hawaii may have helped promote the Mayotte activity.   Forecast 121387 had expected this event was likely within about 100 km of the epicenter around November 15.

An M 4.5 in the Red Sea region east of northern Africa was not reported felt in that region. This is an active epicenter, the last event of M>=4.5  within  about 200 km was an M 4.5 on April 9, 2016. The only event of M>4.5 in the

past 10 years was an M 5.3 on December 23, 2013.   Forecast 121238 had expected this event within about 100 km of this epicenter 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.
