A magnitude 3.8 earthquake shook the East Bay Thursday night, causing little or no damage, according to the U.S. Geological Survey.
The agency reported that the quake struck at 8:16 p.m. and was centered in Berkeley just south of the UC Berkeley campus, near Memorial Stadium — located directly on the Hayward Fault.
The quake was originally reported as 4.2 magnitude and downgraded to 3.9 and then — after being reviewed by a seismologist — to 3.8.
Earlier on Thursday at 2:41 p.m. a 4.0 magnitude quake, with an epicenter at the UC Berkeley Clark Kerr Campus, rattled Berkeley, causing no damage. The afternoon quake was followed by less severe after shocks.
Copying and pasting the coordinates from the agency into Google maps gives the epicenter location.
