3.5, 3.0 Magnitude Quakes Strike East Of Gilroy

by Brandon Mercer

HOLLISTER (CBS SF) — Two earthquakes registering a preliminary magnitude of 3.5 and 3.0 struck east of Gilroy, near Hollister Friday at 4:32 p.m. and 2:44 p.m. respectively, according to the U.S. Geological Survey’s automated seismograph alert network.

Both quakes struck at an estimated depth of just about 4 miles, below the earth’s surface, making this a very shallow quake.

Deeper quakes are less noticeable while a shallow quake–in the 0 to 40 mile depth range–can feel much stronger than their actual reported magnitude. Quakes just below the earth’s surface, in the 0 to 10 miles range, can cause even more damage at lower magnitudes.
