Southern California has been rocked (somewhat gently) by multiple small earthquakes that are coming in fairly rapid (in context) succession.

According to this article in the LA Times:

“Experts said the cluster of earthquakes that began Tuesday night are far from out of the ordinary for Southern California, but that the region has not seen this type of sequence in a few years.

“At a news conference Wednesday morning, Kate Hutton of the U.S. Geological Survey at Caltech said there had been at least 30 quakes since Tuesday night, but only three could be felt by residents.

She said officials are studying the quakes to understand whether it was a swarm or some other type of pattern.”

Time will tell if this has bigger implications.
