South Bay Residents Felt 3.5-magnitude Quake

GILROY, CA — A 3.5-magnitude earthquake Monday rattled parts of the South Bay, the U.S. Geological Survey reported.

The epicenter of the quake was located about 10 miles north of Morgan Hill, according to the USGS website.

The earthquake struck at a depth of about 3 miles. Did you feel it?

A similar size temblor was reported last year to within six days from Monday on July 9 when a 3.1-magnitude was recorded on the Calaveras Fault, a mostly right-lateral, strike-slip fault.

The last notable earthquake produced on the Calaveras Fault was reported on the northern end of the fault line in October 2007: the 5.5-magnitude Alum Rock earthquake, which ruptured to the south, officials indicated on the USGS website.

The southern half of the central segment of the Calaveras Fault has historically been the most seismically active segment, producing the 6.2-magnitude Morgan Hill earthquake in 1984 and a 6.2-magnitude earthquake in 1911, according to USGS. The 5.9-magnitude Coyote Lake earthquake in 1979 ruptured slightly to the south of the other temblors.
