MODERATE EARTHQUAKE IN SUMATRA; JUNO EARTHQUAKES CONTINUE

 

EARTHQUAKE SUMMARY FOR JANUARY 26, 2015

 

Global seismicity was up somewhat over the past several days. An M 5.7 in Sumatra followed a similar sized event in Tonga. The seismicity which accompanied nor'easter Juno in the U.S. also continued. The most unusual event which was probably promoted by stresses from this storm was an M 2.7 which occurred in Pennsylvania as the storm front reached the area. Moderate earthquakes also continued in the Queen Charlotte Islands and Vancouver areas of British Columbia with M 3.7 and 3.7 in the Queen Charlotte Is. area and an M 3.8 in the area of Vancouver Island. In the central U.S. an earthquake approaching the maximum for the area at this time (M 4.3) occurred in Oklahoma. While seismicity in California remained at low levels, there is some previous evidence that this may change following today's earthquake in Pennsylvania.

 

The strongest earthquake in the world today was an M 5.7 in the Nias region of Sumatra, Indonesia. The last earthquake of M>=5.7 within about 150 km of this epicenter occurred on July 5, 2014 (M 6.0 and May 1, 2014 (M 5.8). These appear to be aftershocks of the M 8.1-8.6 earthquake near this epicenter on March 28, 2005. Forecasts  86122 and 86124 expected this activity late in January.

 

NEIC reported this earthquake of M 5.7 in Nias, Sumatra, Indonesia was felt with intensity II-III in the area(s) of Gunung Stoli, Sumatra Utara, Indonesia.

An aftershock of M 4.9 occurred about nine minutes after the mainshock. Aftershocks of large earthquake tend to cluster at 9, 12 and 15 minutes following those events and are close connected with the arrival of PcP, PcS and ScS phases which have reflected off the core back to the epicenter and can help trigger further seismicity in the disturbed epicentral area.

The strongest earthquake in the U.S. today was an M 4.3-4.5 near the Kansas-Oklahoma border. NEIC reported this event was felt with intensity V near the epicenter at Medford, Oklahoma and IV in Tulsa, and Lamont, OK. In Oklahoma, intensity II-III was reported from Prague, Ada, Tankawa, Ralston, Marland, Blackwell, Ponca City, Coweta, Stillwater, Sand Springs, Kiefer, Jenks, Broken Arrow, Bristow, Bixby, Covington, Enid and Oklahoma City. In Kansas areas feeling the tremor at intensity II-III levels included Great Bend, Wichita, Valley Center, Towanda, South Haven, Kingman, Goddard, Derby, Danville, Caldwell, Bluff City, Arkansas City, Anthony, Emporia, Topeka, and possibly Lawrence. A foreshock of M 2.6 was felt with intensity II-II in Kansas at Anthony, Bluff City, Danville and possibly Wichita. An M 2.5 south of this also preceded the M 4.3 and was reported felt with intensity II-III in Oklahoma City and Stillwater, OK.

 

An aftershock of M 3.3 in south-central Oklahoma was felt with intensity II-III in Edmond, Guthrie, Norman and Oklahoma City. An M 2.4 event in central Oklahoma was also felt with intensity II in Guthrie, Oklahoma. The strongest earthquakes in this series have occurred with M4.3-4.5 with the exception of an M 4.8 on November 12, 2014, so this ranks with the strongest of these regional earthquakes.

Light aftershocks continued in the Queen Charlotte Islands area of British Columbia. An M 4.5-5.0 mainshock shook that area yesterday and was likely related to plate stresses from nor'easter Juno. This is the largest earthquake in this area since a similar nor'easter occurred in March 2014. But seismicity did not confine itself to the Queen Charlotte Islands today. An M 3.8 also occurred in the Vancouver Island area west of Tofino. None of these earthquakes were  reported felt in their respective epicentral regions.

An earthquake in southeastern Pennsylvania of M 2.7 also occurred today as the first effects from nor'easter Juno hit that area. The last earthquake of this magnitude within 100 km of this epicenter occurred five years ago on June 3, 2010 with M 2.9. The strongest earthquake in the past 25 years occurred on January 16, 1994 with M 4.2 and 4.6. Readers may recognize the data as the day before the M 6.7 Northridge earthquake. This summary has previously noted the association between events in these two areas. For example when the last such event of M>=2.7 hit in Pennsylvania on June 3, 2010 this summary noted:

 

"In many cases unusually large earthquakes such as those in Pennsylvania and New York occur up to several days prior to moderate to strong earthquakes in southern or central California. That area has been very quiet in recent weeks with the exception of the aftershocks in the Baja, California area. A moderate earthquake in Central California is possible at this time  as a reaction to the M 7.3 in Baja two months ago but we consider this  to be a low probability event at this time. Another possibility would be the Fillmore region of Southern California which saw a light earthquake today. This is an area where stress accumulated following the Northridge earthquake 16 years ago and a moderate earthquake is still possible at some time in this region. Further emphasizing motion along the western  edge of the North American Plate was a series of events of M 3.0 in the Vancouver Island area of British Colombia" (June 4, 2010)

 

Another example comes from the Morgan Hill, California (M 6.0-6.1) earthquake of April 24, 1984 which was preceded on April 23 by the second largest earthquake in this region of  Pennsylvania in the past 50 years (M 4.4). Of course, there have been smaller events in this region which were not followed a day or two later by large California earthquakes and vice-versa and three examples do not generate a convincing argument. However smaller associations are also possible. For example, an M 3.8 on August 26, 2003 in this area of Pennsylvania was followed about a day later by an M 3.8 in the Northridge, California area. This summary noted on August 27, 2003 that this was the strongest event in the Northridge region in more than a year and related this to the event in Pennsylvania as follows:

 

"As in 1994, the New Jersey earthquake was followed several hours later by unusual activity in the Northridge region in the Greater Los Angeles area. An earthquake of M 3.8 was recorded in this area today. This event appears to be the strongest in the Los Angeles region (34-35N 118-120W) in more than a year." (August 27, 2003)

 

The only other such event in the past ten years in this area of Pennsylvania was an M 3.4 on December 27, 2008. This was accompanied by an M 5.9 in  Vancouver about the same time, an M 4.5 in northern California and an M 4.5 in Baja California within a day of the Pennsylvania quake. This was noted in this summary on December 28, 2008. So it appears there is ample reason to expected a moderate quake along the western U.S/Canada border with the Pacific plate in the next several days.

 

Forecast 86265 expected this earthquake within about 25 km of this epicenter was likely to occur at the end of January.

 

NEIC reported this earthquake of M 2.7 in Pennsylvania was felt with intensity I-II in the area(s) of Schnecksville, Paoli, Downingtown, Exton, Glenmoore, Valvern, West Chester and Elverson, Pennsylvania.

A moderate earthquake of M 4.2 also hit the region of Michoacan, Mexico today.

This area has shown increased seismicity since an M 6.8 in Vanuatu of January

23 hit at about 103 degrees from this region. This suggests some promotion due to concentrated seismic waves in the area from Vanuatu. A new tropical storm (TC 08S) formed today at 17S 77E, at the antipode of this Mexican epicenter. The forecast from that storm suggests:

 

"TC 08S formed today in the south-central Indian Ocean with winds up to 45 kts.

It is expected to track to the southeast over the next five days over some active mid-ocean ridges and some local seismicity may be promoted by this storm. The antipode of this is at 17N 102W in the Michoacan area of central coastal Mexico. This region showed increased seismicity yesterday and a moderate to large earthquake promoted by microseisms from TC 08S could be promoted in central Mexico over the next five days. This area is also near 103 degrees from the M 6.8 in Vanuatu of January 23 and this too, could help bring on active seismicity in Central Mexico." (January 26-27, 2015)

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.
