PACIFICA (KRON) -- The earthquake that struck about two miles southeast of Pacifica has been revised to a magnitude 3.7, according to U.S.G.S. officials.
  
The quake hit at 2:57 p.m west of the San Andreas fault, according to U.S.G.S. spokesperson David Oppenheimer. The seismic activity comes on the 105th anniversary of the 1906 Great Earthquake and Fire. 
 
A second, smaller earthquake with a magnitude of 1.4 followed at 3 p.m. That quake was centered about 2 miles southwest of San Bruno.

BART stopped its trains to check the tracks after the first earthquake. Trains are running at normal speeds again.

Caltrain service was not affected, and operations were not altered at San Francisco International Airport.

People across the Bay Area reported feeling the earthquake.
 
Employees at the Lucky supermarket and Safeway in Pacifica told KRON 4 News that they felt the quake but no products fell off the shelves, they said. There was no damage or injuries at either location.
 
KRON 4 viewer Alanna Perez said she felt the quake in Millbrae. It “started with hearing a low rumble then with a bit violent shaking sideways with still a low rumbling noise. Haven't felt one with a good shake like that in a while,” she wrote.

KRON 4 viewer Wendy Burton, who lives in San Mateo, sent a photo a frame that fell during the earthquake (shown above). She said that it sounded "like a tractor trailer hit the house, followed by another strong jolt. Knocked everything off my mantel...and a picture off the wall. Cleaning up lots-o-glass," she wrote.
