The Great San Diego BOOM Mystery - an Update

To update this blog post, yesterday's paper has a more scientific story about the BOOM. Scripps scientists call it a sound wave created about 120 miles off the coast of San Diego, in a military warning area where no civilian flights are allowed:

"According to data analyzed by the scientists, the wave was felt on San Nicolas Island, northwest of San Clemente Island, at 8:40 a.m. It hit Solana Beach at 8:46 a.m., the western edge of the Cleveland National Forest at 8:47.30 and the eastern side of the Salton Sea at 8:53 a.m. From there, it appears to have dissipated.

Elizabeth Cochran, the lead researcher on the project, said the wave moved at 320 meters per second, roughly the speed that sound travels through the air. Its velocity was too slow to be that of an earthquake, she said."

Makes sense.
