Life can serve up a good mystery every once in a while. Weird things happen that defy explanation, that make us wonder how much we really know about the world.
Something of the sort happened in San Diego County shortly before 9 a.m. Tuesday, April 4, and so far no one has come forward with an explanation.
Whatever it was, it caused a woman's bed to shake in Lakeside. It created waves in a backyard pool in Carmel Valley. It set off car alarms in Kearny Mesa and rattled windows from Mission Beach to Poway to Vista. At various spots throughout the county, people reported a rumbling sound or a booming noise.
Scientists insist it wasn't an earthquake. The Federal Aviation Administration has no record of any planes producing a sonic boom by breaking the sound barrier.
Camp Pendleton officials say no activities on the Marine base could have created such a disturbance. There were no large explosions in San Diego County that day, and no meteor fireballs were reported in the sky that morning.
What was it, then?
“My garage door is double steel and it weighs about 500 lbs. It was rattling back and forth like a leaf in the wind for about 3 or 4 seconds.”

Mystery disturbance traced to sound wave
Scripps scientists say it traveled over the ocean to desert

A group of local scientists has uncovered some clues to the source of a mysterious disturbance that rattled San Diego County on the morning of April 4, shaking windows, doors and bookcases from the coast to the mountains.
The scientists, based at Scripps Institution of Oceanography in La Jolla, say the disturbance was caused by a sound wave that started over the ocean and petered out over the Imperial County desert. Using data from more than two dozen seismometers, they traced its likely origin to a spot roughly 120 miles off the San Diego coast.
That spot is in the general vicinity of Warning Area 291, a huge swath of ocean used for military training exercises. The Navy operates a live-fire range on San Clemente Island, which is within Warning Area 291 and sits about 65 miles from Mission Bay.
The researchers also have charted dozens of similar, if less dramatic, incidents that seem to have originated in the same general area of the ocean. They aren't sure what caused any of them.
Peter Shearer, a Scripps professor involved in the research, has no idea whether the April 4 disturbance was natural or made by humans.
Steve Fiebing, a Coronado-based Navy spokesman, said the live-fire range on San Clemente Island was inactive April 4. He also said there was no Navy or Marine Corps flight activity in Warning Area 291 on that day that would have caused a sonic boom or a countywide tremor.
The area, also known in military circles as Whiskey 291, covers 1 million square miles and is off-limits to civilian planes and ships, Fiebing said.
“There was no unusual training that would have caused anything close to what people here felt,” he said.
Cmdr. William Fenick, another local Navy spokesman, said no San Diego-based warships were conducting operations in Warning Area 291 that day.

if it was magnetic and it did that to steel door, then what about cars, metal dustbins, power lines etc etc
An interesting thing is, we have this sorta HAARP thing in San Diego.Along Imperial Beach strand you can view this huge structure of antena.Here is a Google Maps shot you can zoom in on.Not much you can see from there, but here is an image to give you an idea.
This is/was known as AN/FRD-10 CLASSIC BULLSEYE which was shut down in the 1990's
what could it be being used for now?

People for years in L.A. have been reporting "skyquakes" which has led to speculation about the Aurora. Its worth nothing that L.A. and sometimes San Diego are under the flightpaths used by Area 51 when testing the goods.
