No deaths are reported but California Assesses Damage After Second Powerful Earthquake Hits.

A magnitude 7.1 earthquake rocked southern California Friday night, sending tremors that could be felt in Los Angeles, Las Vegas, and nearly 400 miles north in Sacramento. The quake caused fires, power outages and collapsed buildings, officials said.

The powerful quake struck around 8:20 p.m. local time and was centered near Ridgecrest, Calif., a community of 29,000 people on the eastern side of the Sierra Nevada where a 6.4 temblor had hit Thursday morning. The latest quake lasted about 30 seconds and was the strongest in Southern California in 20 years. A series of aftershocks followed.
