San Clemente : 3.9 Temblor Shakes South County Area

No one reported feeling a mild earthquake detected by seismologists Sunday off of San Clemente in the Pacific Ocean, officials said.

The quake, which registered 3.9 on the Richter scale, was the third Southern California temblor of the weekend.

The latest quake struck at 3:42 p.m., said Robert Finn of the California Institute of Technology in Pasadena. He said the epicenter was pinpointed about 31 miles south-southwest of San Clemente.

The quake was news to police dispatchers in San Clemente and Oceanside, and the Orange County Sheriff’s Department said no one called them, either.

“We’ve had no calls at all,” said Debbie Maloney, a San Clemente police dispatcher.

The quake was an aftershock of the July 13, 1986, earthquake in the same area that measured 5.3 on the Richter scale, Finn said.

The region was rattled by two small quakes on Saturday, one an aftershock of the destructive Oct. 1 Whittier Narrows temblor and the other in the border area near San Diego.

The aftershock measuring 3.2 on the Richter scale hit Saturday at 11:40 a.m. and its epicenter was placed four miles southeast of Pasadena on the fault that produced the October quake, which caused millions of dollars in damage.

Earlier Saturday, a quake with a magnitude of 3.0 hit at 8:53 a.m., about 12 miles southeast of downtown San Diego, Finn said.
