STRONG EARTHQUAKE HITS DEEP BELOW FLORES SEA, INDONESIA

 

EARTHQUAKE SUMMARY FOR FEBRUARY 27, 2015

 

A strong earthquake of M 7.0-7.1 hit under the Flores Sea near Timur today at  a deep focus of 572 km. BKG reported it was felt with intensity IV in Denpasar and Mataram; III-IV in Kupang, and Waingapu; II-III in Kuta, Ruteng, Bima and II in Singaraja, Indonesia.  NEIC reported it was felt in Nusa Tenggara Barat, Indonesia at Bima and Matarm with intensity III; in Bali at Denpasar and Kuta with IV and at Ubud with intensity II; in East timor at Oecussi and Dili with intensity II-III. Due to the great depth of this earthquake only slight damage was reported on the surface. EMSC reported moderate shaking in Dili, Timor-Leste, strongly in Klungkung, Bali, and in Denpasar where dogs barked. No tsunami was expected or observed also due to the depth. This is the strongest earthquake of the year 2015 to date. The epicenter is located 10-15 degrees south of the local geomagnetic equator. The current seismic watch had expected this type of activity at this time. That watch stated:

 

"This geomagnetic storm is one of the three most intense during the current year. A global seismic watch is in effect beginning February 24 and lasting through March 2. The most likely areas to see a strong related earthquake are at high latitudes and later in the period at 10-15 degrees from the geomagnetic equator. Areas near 180E and 0E longitude are particularly at risk at this time." (February 24-28, 2015)

 

While the daily earthquake map shows the normal nodal distance, the great  depth of this earthquake will displace these nodes somewhat and readers should expect a more diffuse pattern of far-field aftershocks from the Flores Sea event. The last earthquake of larger magnitude within 200 km of this epicenter occurred as an M 7.9 on June 17, 1996 following a similar event at shallow depth on December 12, 1992. The only other such regional event in the past 25 years occurred on May 24, 1990 with M 7.1. Forecasts 86982 and 87244 had expected a possibly strong earthquake associated with the current geomagnetic storm was likely within about 50-100 km of this epicenter at the end of February or in early March.

 

Both the earthquakes in the Flores Sea and a succeeding series in the northern Mariana Islands including an M 5.7 lie at 148 degrees from the M 6.7 event in  Argentina of February 11. This is a distance at which seismic energy was concentrated following that event and may have helped promote these two sets of earthquakes. It is also located at the seventh node (51.4 degrees) from the most recent strong earthquake - the M 6.9 off Honshu, Japan of February 16.

A strong series of earthquakes in the Anatahan Northern Mariana Islands followed the M 7.1 in the Flores Islands. This epicenter is about 10-15 degrees north of the local geomagnetic equator and this seismicity was probably also promoted by geomagnetic effects as discussed above. The mainshock of M 5.7 was not immediately reported felt in the area but was probably lightly felt in the Saipan region. This is the strongest earthquake within about 200 km of this epicenter since an M 5.7 on January 31, 2015 and the strongest within abou 100 km of the epicenter since an M 6.5 about 100 km south of this on February 5, 2005. Forecast 87918 had expected this event within about 100 km was likely in late February or early March. These earthquakes lie at the core shadow zone boundary from the  South Sandwich Islands M 6.7 of February 16 and from the M 6.7 in Argentina of February 11 and may have been promoted by energy from these events.

The series of earthquakes in the Dallas area of Northern Texas continued today with an M 3.1 event. NEIC reported it was felt with intensity IV in Dallas and II-III in Mesquite, Irving, Garland, Carrollton, Fort Worth, Coppell and Belton, Texas. This is part of a series of events which began on September 30, 2012 with an M 3.4. The last events in the series of M>=3.1 occurred on January 7, 2015 and in late November, 2014 after nearly a year of quiet in the region at this magnitude level. Forecast 87092 expected this earthquake within about 20 km of the epicenter was likely in late February.

Another in the series in eastern Alabama also occurred directly west of the earthquake in Texas today with M 3.1. This series began after 10 years of quiet on November 20, 2014 with an M 3.8 and continued on December 17, 2014 with an M 3.4. Today's event is the strongest event in the region since December, 2014. A smaller event of  M 2.2 occurred on January 22, 2015.  Forecast 87091 expected this earthquake was likely around February 25.

 

NEIC reported this earthquake of M 3.1 in Alabama was felt with intensity II-III in the area(s) of Cullman, Tuscaloosa, Northport, Jasper and Prattville, Alabama.

An M 4.0 earthquake occurred in the area of the Gulf of California today SW of Sonora State, Mexico. This may have been promoted by microseisms from Tropical Storm Glenda which  is currently at the antipode of this event in the South Indian Ocean. This had been a possibility noted in this summary in the previous issue as such:

 

"Tropical cyclone Glenda (14S) continued in the south Indian Ocean today with winds up to 65 kts. This disturbance is currently expected to turn south today.  This is in the general antipodal region of the Gulf of California,  Mexico at 25N 113W. Microseisms from this storm may influence the seismicity in this area with a chance of a moderate earthquake in southern Baja or the Gulf of California while this storm progresses." (February 27-28, 2015)

An earthquake of M 4.9 occurred in the South Indian Ocean south of the eye of TC Glenda. This event was not felt in the area. The antipode of this epicenter is about 37N 127W, west of San Francisco, California. Some sympathetic seismicity in Central California may occur in the next several days. Forecast 87212 had expected this activity in the Indian OCean northeast of this epicenter.

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.
