The notable exception was a 4.1-magnitude quake which hit Rowland Heights at 2:32 p.m. Saturday. The Los Angeles Times reported the quake was "felt across a large area of Southern California," but said  no injuries or damages have been reported as a result of that quake.

And a smaller tremor barged in on a press conference from Caltech geologists about the earthquakes.

But the good news is that the worst of the quakes is probably over. A geophysicist for the U.S. Geological Survey told the San Jose Mercury News California's seismic activity looks to be subsiding for the moment.

"This is fairly typical aftershock activity for an event this size. ... We have been saying there is about a 5 percent chance of a larger earthquake to come. ... That likelihood is decaying very rapidly."
