Editor’s note: While the USGS initially reported a third earthquake in the area at about 6:20 p.m., that notification was deleted after review by a seismologist.

Two earthquakes struck the Lytle Creek area Thursday afternoon, according to the U.S. Geological Survey.

The first temblor had a preliminary magnitude of 3.3 and was reported at 12:30 p.m.

It struck about 6 miles northeast of San Antonio Heights and 8 miles north of Rancho Cucamonga.

Then, about an hour later at 1:25 p.m., a 2.9 quake struck about 9 miles northeast of San Antonio Heights and 13 miles north of Rancho Cucamonga, according to USGS.

Both had a depth of 13 km, the agency reported.
