Three booming sky-quakes in rapid succession.

I was standing outside and heard a large compressional sound wave that sounded like three successive explosions. No craft were sighted and it was heard in an area approximately three miles north of the Ontario International Airport. The news reported that there were people in Orange County (20 miles away) calling in after feeling an earthquake at 15:45 PST. But, Caltech was denying that by stating no earthquake had occurred then.
