San Francisco Earthquake: Second Quake Hits Almost Exactly 22 years After Quake of '89

San Francisco earthquake: A reader board announces that trains will be halted for one minute at the Montgomery Street BART station as part of a statewide earthquake preparedness drill in San Francisco, Thursday, the same day two earthquakes actually hit the city.

Two earthquakes in the United States have taken place on the same day Thursday. The first one took place in Texas, the epicenter of the quake being near rural Karnes County, 47 miles southwest of San Antonio. The quake was a 4.8 magnitude, which was eye-opening because it was a record breaker.

The second one took place in California, the epicenter being two miles southeast of Berkeley near San Francisco. The quake was a 3.9 magnitude, causing a sharp jolt but no immediate signs of damages or injuries.

The quake struck at 2:31 p.m. local time and was at a depth of about 6.1 miles, according to the U.S. Geological Survey.
The quake was felt as a sharp jolt in the East Bay area, and across the bay in San Francisco. It came almost 22 years to the day after the Loma Prieta earthquake struck the Bay Area during the 1989 World Series.
The quake also came on the same day Californians took part in an annual earthquake preparedness drill at 10:20 a.m. Thursday. More than 8.5 million people signed up to participate in the 2011 Great California ShakeOut.
