ENHANCED SEISMICITY CONTINUES IN KERMADEC ISLANDS, NEW ZEALAND

 

EARTHQUAKE SUMMARY FOR MARCH 18, 2019

 

The strongest seismicity in the world today occurred in the central Kermadec Islands of New Zealand. This continues the activation of the region which began about a week ago with the passage of a tropical cyclone through the area. That was accompanied by an M 6.3 in the Southern Kermadec Islands and a number of associated events and on March 15 by an M 5.5 in northern Kermadec Islands.

 

"An earthquake of M 5.5 also occurred today in the northern Kermadec Islands, New Zealand. It was not reported felt in this remote area. This is not an aftershock of the recent strong series in southern Kermadec Islands whihc occurred about 600 km to the south of this epicenter. It represents a new epicenter in this series." (March 15, 2019).

 

Today's activity in the central Kermadec Islands is midway between these two  series. It is the strongest event of M>=5.2 between 31 and 32 South latitude  in the Kermadec Islands since an M 5.4 on March 21, 2015.   Forecast 114454 had expected today's activity was likely around March 17 in  this region.

The strongest earthquake in the U.S. or Canada today was an M 4.1 in Central Alaska. This is an unusual epicenter. The last between 60 and 64N and within the range 154-156W was an 4.3 on April 17, 2000 and prior to that an M 4.7 on April 27, 1992. The last earthquake within about 100 km of this epicenter with M>=4.1 was an M Forecast 114398 had expected an earthquake east of this epicenter was likely with moderate magnitude around March 14.

An earthquake of M 5.1 also occurred near the antipode of the Andreanof Islands, Alaska in the Bouvet Island region of the south Atlantic. The exact antipode is at 54N 172W which is an active seismic zone and could be promoted by events such as this in the Bouvet Islands. The event in the South Atlantic is the strongest within about 200 km of this epicenter since an M 5.2 on February 21, 2018. An M 6.6 on January 28, 2018 may be the mainshock that led to these more recent events.

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.
