The natural disaster struck about 2 kilometers southeast of Berkeley at 2:39 a.m., according to the U.S. "Over 65 miles away, it wasn't big enough to feel here".
The people of Berkeley and nearby cities had awakened due to the severe shaking. Nor, Sanders said, have there been reports of damage to building structures caused by the moderate quake, though "there's always the possibility that there could be some" minor structural damage. But a video posted to Twitter showed products that had fallen from the shelves of a San Leandro Safeway store. The quake hit near Berkeley, California, as a magnitude 4.4.
The historic luxury hotel had no damage, an employee said, declining to give her name.
"Just felt everything shake here in my house in SF and our building emergency alarm went off", someone wrote on Twitter.
Interim San Francisco Mayor London Breed advised residents of the city that "there is no tsunami expected and departments are working on preliminary damage reports".

"The real question is: is this a foreshock to something larger?"
USGS Geologist David Schwartz said the quake struck in an area where there has been 30 earthquakes of magnitude between 3-4 over the last decade.
He suggests residents go over their quake plans with their families.
Knudson said the USGS had learned earthquakes, at least on the southern part of the Hayward Fault, occur every 140, 150 to 160 years. The last big natural disaster on the Hayward fault happened about 150 years ago, in 1868.
The last major quake along the Hayward fault happened in October of 1868, when a magnitude 6.8 hit the San Francisco Bay region, making it the most destructive natural disaster in the state's history. The quake serves as an important reminder that the "Hayward Fault is ready to go", Knudson said. Thirty people died then and there was extensive damage. The past five large earthquakes on Hayward fault have been about 140 years apart, so this fault and the Rodgers Creek faults are the most likely to have a major quake in the bay.
