New earthquake jolts Southern California

An earthquake with a preliminary magnitude of 4.5 was reported this morning in Orange County, Calif., just hours after a 4.4-magnitude temblor and several aftershocks struck in nearby Yorba Linda, according to the U.S. Geological Survey (USGS).

“It’s all just part of the normal seismic activity of California,” John Bellini, a geophysicist for the U.S. Geological Survey told NBC News. “Earthquakes of this size don’t cause a lot of damage.” 

The Orange County quake struck at 9:33 a.m. PT this morning. The night before, at 11:23 p.m., a 4.4-magnitude quake rattled the Yorba Linda area. At 11:25 p.m., a quake estimated at magnitude 2.7 struck in the same area, centered two miles from Yorba Linda. The third temblor -- a magnitude 1.2 -- struck at about 11:41 p.m. and was centered one mile from Yorba Linda.
