A magnitude 4.5 earthquake struck near the Southern California town of Yorba Linda for the second time in just over 10 hours on Wednesday, rattling the Los Angeles area, but no damage or injuries were immediately reported. The latest quake was recorded shortly after 9:30 a.m. (12:30 p.m. EDT) 2 miles (3 km) northeast of Yorba Linda, an affluent Orange County community southeast of Los Angeles that was the birthplace of the late former President Richard Nixon and houses his presidential library and museum.
It was centered about 5.5 miles (9 km) beneath the surface. The earlier temblor occurred at about 9:20 p.m. on Tuesday in about the same area at about the same depth, and was followed by more than a dozen smaller aftershocks overnight, according to the U.S. Geological Survey.
The two 4.5-magnitude quakes were both felt as far away as downtown Los Angeles, about 35 miles (56 km) away, where rattling and rumbling was felt for several seconds at a time.
Earthquakes measured at 4.5, capable of causing light to moderate damage close by, are considered fairly modest seismic disturbances and are relatively common in Southern California.
