A magnitude 3 earthquake struck the Santa Monica Bay this afternoon, a short time after a magnitude 7.2 temblor struck Mexicali.
[Updated, 5:36 p.m.: Caltech seismologists upgraded the Santa Monica quake to magnitude 4.1 and said it's connected to the Mexicali temblor.]
The bay quake occurred about six miles south of Malibu around 4:10 p.m. There were no reports of damage or injuries.
Since the Mexicali quake, there have been other temblors around California, including several in Northern California and one in Julian, a backcountry town in San Diego County. There have also been aftershocks of the Mexicali quake centered in Mexico.
