PRUNEDALE (CBS 5 / BCN) — The U.S. Geological Survey reported a series of earthquakes rattled a section of Monterey County and the surrounding region on Wednesday.

The latest quake was a magnitude 4.0 that hit at 8 p.m.

The epicenter was located 7 miles east-southeast of Prunedale and 42 miles south-southeast of San Jose, according to the USGS.

Authorities along California’s central coast said they received no reports of serious damage or injury from any of Wednesday’s quakes.

The very first quake struck at 12:51 a.m., a tremor with a magnitude of 4.5 near Fremont Peak State Park, according to the USGS. It had a depth of 5.2 miles.

Within an hour of the first tremor, 11 aftershocks rolled across roughly the same area. The aftershocks had a magnitude between 1.2 and 3.4, according to the USGS.

More than 2,300 people in 170 California zip codes reported that they felt at least one or more of the Monterey County quakes on Wednesday, according to information collected by the USGS, with the strongest shaking felt around Salinas and San Juan Bautista and weak shaking reported as far away as Fairfax and Merced.

This marked the second and third times since Saturday that the greater San Francisco Bay Area had experienced a temblor with a magnitude of 4.0 or larger. On Saturday, an earthquake with a preliminary magnitude of 4.1 struck east of San Jose and could be felt throughout much of the Bay Area.

    Is in it a little scary that a year ago so many people were lost in the Haiti earthquake. its just a good thing that this earthquake was not even half of what the Haiti was. Could this really be warnings on bigger earthquakes to come??

      We have earthquakes every week, we just don’t feel most of them.

    The big one is lurking…It will get us when our heads are down.

    These small quakes are great, folks. They help relieve the pressure. Of course the big one is coming, just like in ’89…We have to just be prepared…

    Hi! I felt the one last Friday (1/7) at 4:10 PM at school in east San Jose’ in a portable, early this morning (1/12) at 12:54 AM, and a short time ago at 8:01 PM, the latter two in south San Jose’. At the top of the 8:00 PM local news on KCBS radio, there was mention of an earthquake near San Juan Bautista at 7:54 PM, but perhaps I felt an aftershock. This is eerie, and we need to be prepared, if even minimally. If you have children, make a general plan with them other than cell phone transmission, which may not be functional.

    There was a M6.0+ reported in that area nine hours before the great 1857 quake. It looks to me after watching the pattern of quakes for the past twelve months that we may be nearing a major shift of the San Andreas. Be ready when it happens and don’t assume you will be able to drive anywhere nor have any power or water, especially in SoCal.
