Earthquake San Francisco

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.
Experts have long said the Hayward fault is overdue for a major temblor, which could be especially destructive given it runs under numerous population centers.
The Hayward fault runs along the eastern side of San Francisco Bay and has long been considered one of the most dangerous faults in California. Although it gets less attention than the San Andreas fault, which crosses the city of San Francisco (and extends well into Southern California), the Hayward fault is near population centers in Fremont, Oakland and dozens of other cities.
