At 2:54 pm on Sunday there was ML3.0 quake located 2 miles southeast of Chatsworth. It was felt widely in the San Fernando Valley & from Malibu to Valencia. Some may ask if it was some kind of late aftershock to the Northridge quake. The answer is probably no, since the number of small quakes in area declined to the background level (as it was before 1994) several years ago. That would make Sunday’s quake simply part of the random southern California background activity.
