Minor quake hits Santa Clara County

2.2 magnitude quake is fourth small trembler in past week

The U.S. Geological Survey is reporting an earthquake with a preliminary magnitude of 2.2 struck Wednesday evening in Santa Clara County.

According to the USGS, at 9:22 p.m. the Calaveras Fault tremor rattled an area in the east foothills south of the Calaveras Reservoir. The quake, which had a depth of 2.7 miles, was centered about 7 miles east of Milpitas and 10 miles from San Jose and Fremont, according to the USGS.

In the past week, three other magnitude 2.0 or larger seismic events have occurred along this segment of the Calaveras Fault. Most recently, a magnitude 2.1 quake rippled through the foothills Tuesday night from an area near the reservoir a few miles north of Wednesday's tremor.

The strongest event occurred on Friday, when a segment of the fault between Joseph D. Grant County Park and the reservoir produced a magnitude 2.5 temblor.

These minor earthquake reports might be interesting if they are centered in Palo Alto. When they are on the Calaveras Fault, few people in the east bay will feel them, let alone here.

These articles about the little quakes are interesting to me because they verify that I did feel a tremor when I thought I did. We don't usually have so many little ones on these local faultlines, so it could be significant.

I think it's particularly interesting given that the following was posted to an earthquake sensitive site a couple days ago by someone who has studied quakes for decades:

Hi All. Things are getting interesting in Hollister. The west side of the Calaveras fault has risen about a half inch, or the east side has dropped a half inch, but at any rate there is some deformation occurring. I have never seen this occurring before.

It could be that we no longer have heavy trucks using the street that has allowed the change to take place, or there is indeed a quake in the making. Anything over a 5.0M would do a number on the immediate area. The strongest quake to have occurred in Hollister was a 4.7M in 1970. That quake was just a couple of blocks from the area of deformation. Take Care...Don

There are 100s of small quakes in Calif. every day. It is not unusual at all for California. If you are interested -- like the PA Online staff looking for a story where there is none -- you can follow them each day or each hour.

Time would be better spent getting a preparedness plan/response kit ready for your safety when a serious quake strikes.

Maybe the PA Weekly thinks we need a little shaking up.
