A magnitude 3.1 earthquake rattled the arid eastern reaches of San Diego County on Friday.
The temblor was recorded shortly before 10:30 a.m., centered in the area of Granite Mountain in Anza-Borrego Desert State Park, about 10 miles southeast of Julian, according to the U.S. Geological Survey.
The quake caused no reported damage or injuries.
It's been a while since an earthquake of a significant size shook San Diego. In early December, a 3.6-magnitude earthquake struck near Warner Springs in San Diego County, and September saw a swarm of hundreds of small quakes in Imperial County. The largest was a magnitude 4.9 that was felt in parts of San Diego County and Tijuana, according to United States Geological Survey's Did You Feel It? map.
