An interesting little earthquake swarm down in SoCal. It's probably nothing.

Really, all these little temblors likely do nothing more than relieve stress, making a big boomer less likely.  But who knows for sure?

There have been more than 700 earthquakes recorded in the Fontana area since May 25, ranging from magnitude 0.7 to magnitude 3.2, recorded Wednesday at 5:20 p.m., according to Caltech staff seismologist Jen Andrews. Three of the quakes have been of magnitude 3 or greater.

The swarm initially moved northward, but something unusual began Friday when the swarm turned around and went south, back toward the middle of the activity and the 60 Freeway.

“This is somewhat of an unexpected evolution,” Hauksson said Friday evening. Furthermore, an analysis of the earthquakes shows that activity as of late Friday was fading pretty slowly — slower than would be expected for a typical sequence of aftershocks following a main shock, he said.

“That would suggest it’s going to continue for — I don’t know — at least several weeks,” Hauksson said Friday. “We’re watching what’s happening and trying to track that activity.”

By Saturday afternoon, earthquake activity had deceased significantly. “This is difficult to interpret, but it suggests that the sequence is now decaying somewhat similar to an aftershock sequence,” Hauksson said. “There will be fewer and fewer events as time goes on.”
