The pair of earthquakes that rattled the San Francisco Bay Area on Monday were caught on tape during a morning television news show. "I believe we are feeling an earthquake right now," KGO-TV's Kristen Sze said at 5:33 a.m. when the 3.5 and 4.0 quakes struck. "It's a pretty big earthquake. The studio is shaking." Another anchor then noted lights were shaking in the studio.

The quakes occurred in the East Bay town of El Cerrito.

According to the USGS' "Did You Feel It?" Web page, the temblor was felt from Santa Cruz to beyond Santa Rosa. It was particularly reported by Oakland, Berkeley and other East Bay communities close to the epicenter. BART temporarily halted service for track inspection but the transit service quickly resumed.

Seismologists believe the quake occurred along the Hayward fault.
