Two days after two earthquakes with magnitudes of 4.4 and 4.3 struck near Santa Rosa, Calif., another small earthquake hit the SAN FRANCISCO BAY AREA Bay Area this time around in Berkeley, the U.S. Geological Survey said.

The magnitude 2.9 tremor struck at 2: 41 a.m. on Thursday with a depth of 5.5 miles just behind the Fairmont Hotel-Claremont Club and Spa in Berkeley, based on the USGS map. The epicenter was 3.1 miles northeast of Emeryville and 4.6 miles north of Oakland.

Weak shaking was felt through the entire East Bay and SAN FRANCISCO BAY AREA, and much more than 900 people reported feeling the earthquake to the USGS.

The quake hit on the Hayward Fault that runs between San Pablo Bay to the north and Fremont south, passing by way of a highly populated section of the Bay Area, like the cities of Berkeley and Oakland, the USGS said.

The East Bay also saw a magnitude 2.9 quake on Sept. 11, the USGS said. The tremor hit at 10: 31 p.m., with a depth of 6.2 miles near Piedmont, based on the U.S. Geological Survey.

The biggest quakes to recently hit the Bay Area occurred in the North Bay: a magnitude 4.4 tremor at 6: 39 p.m. on Sept. 13 and a magnitude 4.3 just a minute later at 6: 40 p.m. Both hit in exactly the same area near Santa Rosa. The quakes struck on the Rodgers Creek Fault, that is area of the San Andreas system.

The Rodgers Creek fault is area of the San Andreas system. The final big earthquake onto it was in the 18th century,said Lucy Jones, a California seismologist and writer of The Big Ones, on Twitter. It includes a longterm slip rate slightly below 1 cm/yr which puts it in exactly the same class as Hayward, Garlock or San Jacinto.
