A magnitude-3.9 earthquake in Orange County rattled homes and offices late Monday morning, although there have been no reports of serious damage so far.
Radio producer Terri McIntosh was taking calls for New Life Live Ministries when the quake struck.
"We heard it. We heard the earthquake," McIntosh told his guest over the air.
The epicenter was located one mile west of San Juan Capistrano and two miles north-northeast of Dana Point. It struck at 10:37 a.m.
Firefighters from Buena Park to San Clemente immediately went on alert, pulling trucks out of fire stations before surveying cities for damage.
No earthquake-related damage has been reported, said Orange County Fire Authority Fire Captain Marc Stone. A Southern California Edison represntative told NBC4 the quake did not impact the San Onofre Nuclear Power Plant, located about 15 miles south of San Juan Capistrano.

"It was a tremendous jolt," said Anna Bryson, a trustee with the Capistrano Unified School District.
The quake lasted between seven to 20 seconds, according to witnesses.
Inside a Laguna Beach gourmet food store, glasses stayed upright, the pottery held tight and there wasn't a splash of salad dressing anywhere.
The big jolt was a first for a couple visiting from Chicago.
"The funny thing is you think you're losing your balance, you think it's something with your body," said tourist George Tomaszewski.
NBCLA Facebook visitors reported feeling the quake over a widespread area, including Garden Grove, Newport Beach, Glendale and as far east as Riverside and Temecula.
