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 in Hayward. There were no reports of any injuries or damage in Oakland, the city’s fire department confirmed to USA TODAY Thursday.

Several other earthquakes struck further north this week

Earlier this week, four earthquakes shook further north on the coast of Humboldt County.

A moderate earthquake of magnitude 4.5 was reported at 8:33 p.m. Tuesday off the coast near Petrolia, south of Eureka, USGS reported. Three smaller quakes followed suit throughout the night with the the last (3.0 or stronger) reverberating at 1:22 a.m. Wednesday, according to the USGS.

Before those four earthquakes, a 4.1 magnitude temblor hit the same area in the middle of the night on Tuesday, at 12:13 a.m., according to Southern California Earthquake Data Center.

The temblors come two months after a magnitude 7.0 earthquake led to a tsunami warning after striking near the town of Petrolia. The quake happed in a seismically complex area referred to as the Mendocino Triple Junction. 

A 2.9 earthquake also struck near Petrolia on Thursday at 11:40 a.m. ET with a depth of over 11 miles, the USGS reported.
