3.4-magnitude quake and two others rattle San Francisco Bay Area, USGS reports

A 3.4-magnitude quake hit near San Leandro in the San Francisco Bay Area at 11:43 a.m., the largest of three temblors in the area Sunday morning, the U.S. Geological Survey reports.

Dozens of people from as far away as Sacramento and Modesto reported feeling the 6-mile deep tremor, according to the agency.

A 2.6-magnitude quake shook San Leandro at 11:36 a.m. and a 1.3-magnitude tremor hit nearby at 11:45 a.m., the U.S. Geological Survey reported.

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.
