A large rolling earthquake centered 11 miles from Ridgecrest, CA. at 8:19 PM, was felt all the way to Mexico. The epicenter was again in the same relatively remote area as the July 4th quake: approximately 100 miles from downtown Los Angeles, in San Bernardino County.
In our newsroom, near LAX, the walls swayed and it was as if we were on a ship. Having been in the same location during the July 4th quake I can say that the difference was that this one lasted about twice as long. It was immediately clear that it was a higher magnitude.
For us near the coast, it is fortunate that the epicenter was approximately the same as the last one – approximately 150 miles inland
