MODERATELY STRONG QUAKE HITS ATACAMA, CHILE

 

EARTHQUAKE SUMMARY FOR JUNE 24, 2016

 

The strongest seismicity in the world today continued in the region of central and Northern Chile where an M 5.8 was felt in the area of Atacama, Chile.

CSN reported this earthquake was felt with intensity V in  Tierra Amarilla, Copiapo, IV Taltal, Caldera, Diego de Almagro, Huasco; III Antofagasta, Mejillones, Chanaral, II Sierra Gorda. Felt in Antofagasta and Atacama.

NEIC reported this earthquake of M 5.5 in Central Chile was felt with intensity IV in Copiapo, Atacama and II-III in the area(s) of Diego de Almagro, Atacama, Chile.  There were no reported damages with this quake despite its magnitude. The last earthquake within about 150 km of this epicenter to occur with M>=5.8 was recorded on November 27, 2015 (M 6.2) and prior to that as an M 5.8 on May 19, 2012. Forecast 99240 had placed this activity about 150 km to the north of this epicenter at the end of June.

A moderate earthquake of M 4.2 shook the region of Istanbul, Turkey today after

an M 3.2 foreshock. EMSC reported this earthquake was felt with moderate intensity in Turkey at Pendik, Kartal, Atasehir, Kadikoy, Istanbul, Fatih, Beykoz, Buyukcekmece, Turkey. The foreshock of M 3.0 was felt lightly in Pendik, Uskudar and Kadikoy, Turkey. A strong, possibly destructive, earthquake is expected in this region in the near term and these may be foreshocks to such an event. It is most likely  at times of high tidal and/or geomagnetic stresses. A sign that such an event is approaching is the increasing frequency of moderate earthquakes in the region. The last event of M>=4.2 within about 100 km of this epicenter occurred on January 1, 2016 while the last of larger magnitude was an M 4.4 on November 16, 2014 and of M 4.7 on July 11, 2011. Forecast 99176 had expected today's activity within about  40 km of the epicenter to occur at the end of June.

 

NEIC reported this earthquake of M 4.2 in northwestern Turkey was felt with intensity IV in Korfez, Kocaeli and II-III in the area(s) of Sultanbeyli and Istanbul, Turkey.

An earthquake of M 4.6 also hit near the Cook Strait in New Zealand today.

GeoNet reported this earthquake was felt with strong intensity east of Seddon, South Island, New Zealand. Moderate to strong intensity was reported to GeoNet from most communities in southwestern North Island and northeastern South Island with nearly 1000 people reporting shaking. Strong intensity was reported from Lower Hutt with moderate shaking in Redwoodtown, Blenheim, Linden, Broadmeadows, Karori, Lyall Bay, Muritai, Porirua, Tawa, Paparangi, Thorndon, Kilbirnie, Owhiro Bay, and Lowry Bay, New Zealand. This is the second moderate earthquake in the region in the last three days perhaps representing activation of the area. Forecast 99262 had expected this event within about 50 km of the epicenter was likely around June 23-25. The  last earthquake of M>=4.6 within about 100 km of Wellington, New Zealand was recorded on February 22, 2016 with M 4.7. The last of significance in the region was an M 6.1 on April 24, 2015.

A light earthquake of M 3.8 hit the Baffin Bay Seismic Zone today. This is a  remote area of eastern Canada. This joined a reintensification of the seismic activation of the Reykjanes Ridge in the North Atlantic. Forecast 98958 had expected the Baffin Bay event was likely within about 25 km of this epicenter around June 20. Earthquakes in this region of M>=3.8 have tended to occur

in late winter with the last three such events in February, 2015 and 2016 and in March 2014. The earthquakes in the North Atlantic were expected in forecast 99199 to occur around June 24.

The Aleutians of Alaska continued to be the most active region of the U.S. and Canada today. Two moderate earthquake of M 4.5 and 4.9 hit the region today in the western zone of the Rat Islands. This is a remote area and these events were not reported felt. The earthquake of M 4.9 was the strongest in the Rat Islands since an M 5.0 on May 4, 2016. Forecast 99201 had expected today's activity within about 100 km around June 25. These are aftershocks of an M 7.9 earthquake that hit the Rat Islands two years ago on June 23-24, 2014.

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.
