This M4.2 EQ is normal activity for SoCal. A M3.0 foreshock 1/2 hr before. This area has had plenty of EQs in the past.— Dr. Lucy Jones (@DrLucyJones) January 4, 2015
A 3.0-magnitude earthquake occurred about 10 minutes before the larger quake hit, the USGS said.
@ABC7 Felt the quake in North San Gabriel. Hit hard and shook back and forth. Only felt about 4-5 seconds. All OK.— Miss T. (@myteacherMissT) January 4, 2015
The quake could also be felt in the Los Angeles area and south toward Long Beach, according to the USGS.
