2.7-magnitude quake rattles San Francisco Bay Area in California, seismologists say

A late-night 2.7-magnitude earthquake shook the San Francisco Bay Area in California, the U.S. Geological Survey reported.

The 4-mile deep quake hit 2 miles from San Leandro at 10:59 pm. on Monday, Jan. 9, according to the USGS.

Hundreds of people from as far as Concord and San Francisco reported feeling the tremor to the agency.

San Leandro is a city of 91,000 about 20 miles east of San Francisco.

Magnitude measures the energy released at the source of the earthquake, the U.S. Geological Survey says. It replaces the old Richter scale.

Quakes between 2.5 and 5.4 magnitude are often felt but rarely cause much damage, according to Michigan Tech. Quakes below 2.5 magnitude are seldom felt by most people.
