The rumbling appears to have actually been caused by a supersonic Navy flight.
The U.S. Navy confirmed an aircraft flew faster than the speed of sound as part of an exercise with the USS Ronald Reagan aircraft carrier about 50 miles off the coast this afternoon.
The sonic boom at around 1 p.m. was felt across a wide area, from Malibu to Orange County. Many assumed it was an earthquake, but Caltech seismologists said they did not record any earth movement.
Also weird booms in Louisiana today.

Mysterious rumbling along coast wasn't earthquake, experts say
Breaking - Large and Loud Event shakes Orange County CA - Not an earthquake!!
I live in Huntington Beach and whatever it was scared the heck out of us and shook the whole house. Would love to hear what ATS thinks it is bc it was not an earthquake. I have freinds in LA and as far south as San Clemente and they felt it too, which makes it even crazier that it wasnt an earthquake. I just cant think of a natural event capable of this besides and earthquake.edit on 9-4-2014 by tonycodes because: (no reason given)edit on 9-4-2014 by tonycodes because: (no reason given)edit on 4/9/2014 by semperfortis because: exact headline

Sonic boom would make sense, but as the article states, only military aircraft would exceed the speed of sound. Military aircraft do not fly supersonic in civilian airspace (Orange County) however.edit on 9-4-2014 by Wookiep because: (no reason given)
What makes you speculate it's the X 37B ?
Question............if the plane is going at Hyper speed...say mach two or three....does that multiply the boom......
