Multiple earthquakes shook California’s Bay Area Thursday afternoon.

The earthquakes occurred near Hayward, around 20 miles southeast of Oakland, with the strongest one hitting at 1:59 p.m. local time, according to the U.S. Geological Survey.

The strongest temblor, which was recorded at a depth of 4.3 miles, measured a preliminary magnitude of 3.7 in Alameda County, which neighbors San Francisco.

Other earthquakes of magnitudes 3.3, 3.2 and 2.7 were also recorded near Hayward, according to the USGS.

It was not immediately clear if there was any damage.

This is a developing story.
