A magnitude 5.0 earthquake struck northern California's Napa region on Friday, the U.S. Geological Survey said.

Comment: Oddly, at the time of this writing there is nothing listed on USGS.

The quake hit 7 miles/11 km northeast of Napa at a depth of 3 miles (5 km). The temblor could not be felt in San Francisco, a witness said.

it was a mistake

I thought it was odd, because I surely would've felt something here in Santa Rosa.

Northern California quake was a mistake, USGS says

SAN FRANCISCO, April 30 (Reuters) - The U.S. Geological Survey accidentally reported an earthquake in Northern California because scientists did not review an automated alert, a geophysicist said on Friday.

The USGS system had reported a magnitude 5.0 quake near the Napa region on Friday afternoon, but geophysicist Paul Caruso later said there had been no quake. (Reporting by Peter Henderson; Editing by Doina Chiacu)
