Sonic boom causes mystery jolt in Orange County

NEWPORT BEACH, Calif. (AP) — Some folks in Orange County thought they might be having another earthquake as a mysterious boom rattled buildings and nerves nerves — but the culprit turns out to be from a higher source.

The jolt and a loud boom were reported at around 1 p.m. Wednesday.

No damage or injuries were reported.

Some frazzled folks wondered if it was yet another aftershock to a magnitude-5.1 temblor that struck the county on March 28.

However, the California Institute of Technology said no quake was recorded in the area at that time.

The source turned out to be a sonic boom.

The Los Angeles Times (http://lat.ms/PTkBFq ) says the Navy confirmed that an aircraft broke the sound barrier during an aircraft carrier exercise 50 miles off the coast.
