Southern Calif. Shakes From Another Quake

(CBS/AP) YORBA LINDA, Calif. - Another moderate earthquake has shaken a wide area of Southern California.

The U.S. Geological Survey says the 9:33 a.m. Wednesday quake was centered two miles northeast of the Orange County city of Yorba Linda.

The quake was initially measured at magnitude-4.5 but seismologists have since lowered the magnitude to 4.1.

There had been no immediate reports of damage or injuries, according to CBS Los Angeles.

A magnitude 4.4 quake centered in the same area struck late Tuesday night. No damage was reported.

"They're definitely a related sequence," Lucy Jones of Caltech told KNX 1070 NEWSRADIO. "Five percent of the time you get something bigger, here we hit it exactly on the same."

Yorba Linda is about 35 miles southeast of downtown Los Angeles.
