LONE PINE, Calif. — Earthquakes up to magnitude 5.2 struck Friday evening in a remote area of eastern California that was been shaken by a sequence of temblors a day earlier.

...The quakes' epicenters were just southeast of the town of Lone Pine in the arid Owens Valley below the eastern slope of the Sierra Nevada, about 180 miles north of Los Angeles.

"It's a very robust sequence," said California Institute of Technology seismologist Anthony Guarino.

The 5.2 quake occurred at 6:15 p.m. at a very shallow depth and was preceded by tremors of 4.7 and 4.9 in a six-minute span, the U.S. Geological Survey said.
