Aftershock Hits Northridge Area

Another late aftershock from the deadly 1994 Northridge earthquake hit Southern California early Sunday, a day after a wave of quakes hit the same area. No injuries or serious damage were reported.

An earthquake expert called the the unusual 24-hour turnaround “mildly surprising.”

The 4.9-magnitude quake Sunday was centered about 13 miles northwest of the 1994 Northridge earthquake, the same location as some of Saturday’s quakes, said Steve Bryant, seismologist at the California Institute of Technology in Pasadena.

Because of their locations, depth and other factors, all of the weekend quakes were considered aftershocks of the 6.7-magnitude Northridge quake, which killed 72 people.
