Mysterious 'Sky Quakes' Rattle Nerves in the O.C.

DANA POINT -- Some mysterious shaking is rattling nerves in Orange County.  But, there may be a simple explanation.

Thousands of people reported feeling shaking and window rattling Tuesday night about 9:20 p.m.  Experts say it wasn't an earthquake, but likely a sonic boom produced by a high speed jet, according to Bob Dollar, a seismologist at the U.S. Geological Survey.

"This morning Kate Hutton (of Caltech) reviewed seismograms from the event last night," Dollar said in an email. "These data are consistent with a sonic event coming onshore near Dana Point and traveling northward inland." 
The F/A 18 Super Hornet fighter jets used in Southern California by the Navy and Marines are capable of breaking the sound barrier and producing a sonic boom felt on the ground, but no one reported seeing the high flying jets.

The same thing happens locally when the space shuttle lands at Edwards Air Force Base but, there are currently no shuttles in flight.

Residents reports feeling rattling of their doors and windows but were surprised to see other things, like wind chimes still. Others say they noticed their dogs acting funny and said the shaking felt like someone was pounding on their front door.

So far, neither the Air Force nor the Navy has confirmed the flight of any supersonic jets in the area.

Hope it's nothing for the small quakes.

Any reports of mysterious cylindrical “meteors” buried in the ground out at the Wilmuth Farm?

“So far, neither the Air Force nor the Navy has confirmed the flight of any supersonic jets in the area.”

Easy puzzle to solve. Just call up the tower at Area 51 and ask for the flight operations for the days in question.

PS I’m not quite sure the information operator has the tower number. But surely it is on Google.
