Strange Sound Reported in San DiegoThe sound was felt or heard in all corners of San Diego CountyBy R. Stickney and Lauren SteussyFriday, Jun 29, 2012 Updated 4:34 PM PDTResidents from Chula Vista to Oceanside reported a large rumble around 12:45 p.m. Friday.The mysterious sensation was described by some people as sounding like a door slamming while others said it was strong enough to rattle windows.A check of the U.S. Geological Survey website showed no earthquake activity.NBC 7 San Diego's Dagmar Midcap was in Del Mar at the time and described it as a "Sonic 'rumble'" She tweeted, "according to my contacts at USGS, not seismic but rather sonic."Two months ago, when San Diegans heard a similar sound, there was evidence of chaff on weather radar. Chaff is a material sometimes emitted during military exercises.On Friday, however, Tina Stall with the National Weather Service said there was no visible chaff in the area at the time the noise was reported.The mysterious sound had both residents and experts scratching their heads. Scripps Institution of Oceanography scientist Kristoffer Walker said he felt it too, and looked into microphones recorded from MCAS Miramar.Evidence from his research revealed an answer."There was indeed an atmospheric tremor, or 'skyquake,'" Walker said. "The likely cause of these 'skyquakes' is routine military activity very far off the coast of San Diego (at least 50 miles away) in zones that are designated military training zones."Typically, we don't hear these "skyquakes." But when the wind reaches speeds of over 100 miles per hour, the sound can reach parts of San Diego, Walker said.A spokesperson from Camp Pendleton said Marines are not training with anything unusual. They often train with various military equipment and will be training with tanks both Saturday and Sunday.

Did anyone get the nadin dictionary done yet? I can't make head or tails of what she is rambling about.
Window rattled because you broke wind you gas bag.
Kinda mean attack on a poor woman with irritable bowel syndrome. Or was that diverticulitis?
That's the other DUmmy, the one that fancies herself some sort of school teacher.
I actually heard my first sonic boom a few weeks ago. It woke me up. I thought it was thunder until I noticed the sky was perfectly clear. It wasn't long before they were breaking in on TV saying that a jet had flown too close to the coast and the sonic boom was heard all along the GA coast. It rattled my windows.
