Forty-five quakes of magnitude 3.0 have struck Southern California on Wednesday, the largest of which was a magnitude 4.9.
Dr. Lucy Jones, a seismologist, founder & chief scientist at her center, said
it is one of the largest swarms we have had in the Imperial Valley - and it is historically the most active swarms in Southern California.Several swarms of earthquakes occurred near San Andreas.
Wednesday evening from around 4:30 p.m. to 6:05 p.m. there has been an M4.4, M4.9, and most currently a M4.2.
Jones said they are too far from the San Andreas fault to change the probability of a quake on it.
