A series of earthquakes — the largest with a preliminary magnitude of 4.7 — struck the California-Nevada border area Thursday night but there were no immediate reports of damage or injuries.
The largest temblor struck at about 9:35 p.m. and was centered about 10 miles (16 kilometers) from Soda Springs, Calif. and about 27 miles (43.4 kilometers) west of Reno, according to the U.S. Geological Survey.
It was preceded by a magnitude-3.2 quake about nine minutes earlier and followed by a magnitude-3.1 quake that struck about 2 1/2 minutes later, seismologists reported.
The quakes were in Sierra County, north of Lake Tahoe.
