Cerro Prieto Volcano Earthquakes, Mexico - John Seach

An earthquake swarm occurred under Cerro Prieto volcano in Mexico between 8-11 February. The seismic swarm began on 8 February 2008 at 11:12 pm (Pacific Time) with a magnitude 5.1 earthquake. A second magnitude 5.1 earthquake occurred on 11 February 2008 at 10:29 am (Pacific Time) about 4 miles further south. Both events, were shallow, at a depth of less than 3 miles. Sixteen earthquakes greater than magnitude 3 have been recorded over 2.5 days. The two magnitude 5 earthquakes were tectonic, consistent with activity on the Cerro Prieto fault. Cerro Prieto geothermal field is located at the volcano, and there is evidence that earthquakes at the volcano may be related to fluid extraction at the field.
