Unexplained boom
An unexplained boom is a very loud noise similar to a sonic boom created by the supersonic flight of an aircraft. However these booms are unexplained for various reasons - for instance because no supersonic flight was scheduled at the time the boom was heard.
Media in the US reported several unexplained booms. This phenomenon is rarely reported outside the US.

- Bob Dollar of the USGS told the Register that Caltech scientists reviewed seismograms from Tuesday night's event in Orange County. "These data are consistent with a sonic event coming onshore near Dana Point and traveling northward inland," Dollar said. "The energy traveled across our seismic sensor network at the velocity of a compressional wave in air rather than the velocity of a similar wave through the ground, which is much faster," Dollar said.[4]
