An earthquake with a preliminary magnitude of 4.5 centered in Contra Costa County was felt in the Palo Alto area on Monday night.

A Palo Alto police and fire dispatcher reported one resident calling the dispatch center to report feeling the quake. No reports of injuries or damage from the earthquake were made as of 11 p.m.

More than a dozen people in Palo Alto or surrounding cities took to Twitter minutes after the quake with reactions to the jolt.

"Felt the #earthquake shakes in Palo Alto, minor over here," tweeted James Lewis, creator of AddOhms Tutorials.

"#earthquake felt in Palo Alto, working at my desk upstairs like something slammed my chair," tweeted historian Adrienne Mayor.

The 4.5-magnitude earthquake was preceded by a 2.5-magnitude temblor at 10:23 p.m.

As I imagine is true with most people in Palo Alto, we felt it as a quick jolt. In fact, I thought that someone might have hit our building. I'm always concerned that something like this could be a seismic foreshock.
