Quake Hits Remote California Area
TEMECULA, Calif. — A moderate earthquake struck early Monday in a remote area of the Cleveland National Forest in northern San Diego County.
There were no reports of damage or injury.
The magnitude-4.1 temblor struck at 4:35 a.m. about 10 miles north of the Palomar Observatory and about 20 miles east of the Riverside County community of Temecula, according to the U.S. Geological Survey.
It was followed by a magnitude-3.8 aftershock five hours later, the USGS said.
The observatory was closed when the quake struck.
The quake was felt from San Diego to Palm Desert, said Caltech seismologist Anthony Guarino.
