LAKE COUNTY, Calif. — A series of earthquakes rattled parts of Lake County on Saturday morning.

The first and largest of the quakes was a 4.3-magnitude shaker just inside the Sonoma County line at 7:30 a.m., according to the United States Geological Survey, or USGS.

The USGS said it received 236 shake reports on that quake. One of the reports came from San Diego.

Many Lake County residents reported on Facebook that the earthquake gave them a good shake.

A minute later there was a 3.1-magnitude aftershock to the northeast of the first quake, this time just inside Lake County’s border. That quake resulted in five shake reports, the USGS said.

The USGS said a second aftershock, measuring 2.5 in magnitude, was recorded at 7:32 a.m. near Cobb, also in Lake County.

That aftershock, like the first, resulted in five shake reports, the USGS said.
