An earthquake measuring 3.5 hit just after 7:45 a.m. in the ocean off the the San Francisco Bay coastline, the USGS reported.
It was five miles deep and was recorded three miles from the San Francisco Zoo; eight miles from San Francisco City Hall on the San Andreas Fault, the same one where the 1906 quake hit.
Danielle Brown, a server at Louis' Restaurant on Point Lobos Avenue near the Cliff House, was walking up the stairs from the restaurant's basement when she heard a strange sound.
"The whole building kind of shook a little, it made a rumbling sound," she said.
Golden Gate Bridge patrol Sgt. H. Lopez was near the bridge's toll plaza when the quake hit.
"It was very quick, it was like a big truck going by," he said. "When I came back to the office our seismic alert had gone off."
Christian Andino, a barista at Java Beach Cafe on Sloat Boulevard near the zoo, said the temblor startled customers.
"There was a little shaking going on, things were moving on the shelves slightly," he said.
BART had system delays while their experts inspect the tracks, a routine step after a Bay Area quake.
The Twittersphere is buzzing with reports from San Franciscans who say the jolt woke them up. Did you feel it?
