Ridgecrest earthquake was intense. Exactly how strong was it?
LOS ANGELES - The Fourth of July Ridgecrest earthquake measured 6.4 magnitude.
It was the strongest quake to hit Southern California in years, but it was actually significantly less powerful than some earlier temblors.
That includes the 6.7 Northridge quake in 1994 and the 7.1 Hector Mine quake in the Mojave Desert in 1999.
Caltech officials believe it was the most widely felt quake in Southern California since the 7.2 Mexicali temblor in 2010.
