Brian Garcia, a meterologist for the National Weather Service San Francisco Bay Area, said he felt the earthquake at their office.
Officials believe that a 5.1 magnitude earthquake rattled Northern California Tuesday afternoon. The earthquake was centered east of San Jose but shook much of the Northern California and the Bay Area.
The United States Geological Survey team recorded the earthquake about 8 miles east of Seven Trees, California, after 11:30 a.m. local time.
What we know:
According to the National Earthquake Information Center, California experiences two or three earthquakes each year that can cause sizable damage and register a magnitude of 5.5 and higher.
Initial indications were that the Calaveras Fault, which is part of the San Andreas Fault system, triggered the shaking.
The earthquake was only centered about 4 miles underneath the surface, which is considered to be a shallow quake and likely contributed to millions feeling the shaking.
