BARDARBUNGA, ICELAND ERUPTION INTENSIFIES

 

EARTHQUAKE SUMMARY FOR SEPTEMBER 1, 2014

 

The eruption of Bardarbunga volcano in Iceland is getting stronger and is now clearly visible on webcam. About 700 volcanic tremors are occurring in half a day in the region at this time. Most of the action is occurring on the northern side of the fissure. A volcanic plume up to 15000 ft in altitude formed above Bardarbunga Volcano in Iceland today and extended up to 100 km to the northeast. There was no indication of ash in this cloud. The lava eruption continued with about 100 cubic meters per second being extruded. Lava was being spewed tens of meters high with the volume of erupted lava to data about 25 million cubic meters. Earthquakes of M 5.3-5.4 and M 5.0 were recorded near Bardarbunga today.

The largest earthquake in the U.S. today was an M 3.5 in the Gilroy area of Central California south of San Francisco. Forecast 82754 expected this event was likely around August 30 within about 25 km of this epicenter. It is the strongest event within 50 km of this epicenter since an M 3.7 on December 2, 2013 and the strongest of the year 2014 to date. An M 3.8-4.1 hit about 55 km southeast of this epicenter on August 21 and may have been precursory to the M 6.1 150 km to the northwest in the Napa region of California three days later on August 24.

 

NEIC reported this earthquake of M 3.5 south of San Francisco, CA  was felt with intensity II-III in the area(s) of Redwood City, Sunnyvale, San Francisco, San Mateo, Fairfield, San Ramon, El Sobrante, Atos, Aromas, Gilroy, Hollister, Los Gatos, Morgan Hill, San Juan Bautista, San Martin, Watsonville and San Jose, California. An aftershock of M 2.1 was felt in San Leandro, Walnut Creek, Gilroy, Morgan Hill, San Martin and San Jose, California.  The quake appears to have occurred on the Calaveras Fault. This activation of the central to northern California area since August 20 is remarkable and more significant earthquakes in this area may yet occur in the next two weeks.

The strongest earthquake in the world today was an M 5.2-5.5 in Southern Peru near Lima. This epicenter lies on the geomagnetic equator and is probably promoted by the current geomagnetic storm. IGP reported this earthquake was felt with intensity III-IV in San Juan de Marcona, III Nazca, Peru. NEIC reported intensity V in Nazca, Ica, Peru and II-III in the Lima Provinces at Chosica and San Luis, Peru. Forecast 82880 had expected this region to be active at the end of August or early September. While not at the same epicenter, this is probably a regional aftershock of the M 7.0 of September 25, 2013 about 100 km south of this. That was the last event near this epicenter of M>=5.2.

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.
