(UPDATE: 6:42 p.m.): 45 quakes greater than a 3.0 magnitude, the biggest was a 4.9 magnitude earthquake, and this constitutes the largest earthquake swarm in SoCal history.

Dr. Lucy Jones said it is one of the largest swarms we have had in the Imperial Valley - and it is historically the most active swarms in SoCal.

Swarms of earthquakes happening south of the San Andreas, three over a 4.2 magnitude in an hour.

Wednesday evening from around 4:30 p.m. to 6:05 p.m. there has been a 4.4, 4.9, and most currently a 4.2 magnitude.

According to Dr. Lucy Jones, Seismologist, Founder & Chief Scientist at her center, they are too far from the San Andreas to change the probability of a quake on it.

She tweeted her updates around 5 p.m. Wednesday.
