Earthquake swarm reported at California’s Coso Volcanic Field
Posted on December 4, 2012
December 4, 2012 – CALIFORNIA - An
energetic earthquake swarm centered beneath rhyolite domes in the Coso
Volcanic Field (CA) continues, with over 20 earthquakes ranging between
M1 and M3 so far today. Many smaller events (hundreds) are recorde
d
as well. The swarm initiated on 27 November and has included
earthquakes as large as M3.7. The Coso Volcanic Field is located in Inyo
County, California, at the western edge of the Basin and Range geologic
province and northern region of the Mojave Desert. The Coso Volcanic
Field is one of the most seismically active regions in the United
States, producing dozens of tremors in the M1 and M2 range each week.
Tremors in the M3 range occur at a rate of 2-6 per month and M4 quakes
occur two-three times each year. Recent activity in the M5 range
happened in 1996 and 1998 when tremors of M5.3, M5.1, M5.2, and M5.0
occurred with a day of each other. These tremors were actually recorded
along the eastern side of the Coso Volcanic Field, 15 miles (24 km).
September 30, 2009 to October 6, 2009 there have been 429 earthquakes
ranging from 0.1 up to a 5.2. Some days have activity just about one
every minute. On October 2, 2009 there were three earthquakes (5.2, 4.7,
and a 4.9) all within one hour of each other. Earthquake swarms are
common in the Coso area, often producing hundreds of tremors over
periods of time as short as a few days. This kind of brisk and robust
seismic activity is common in volcanic areas, such as Long Valley
Caldera located near Mammoth Lakes, and Yellowstone Caldera at
Yellowstone. Geologists say the last eruption of the volcanic fields
occurred 30 to 40,000 years ago. –Earthquake Report, Wikipedia
