Listening (literally) to the Japanese earthquake

NOAA has an audio of seismic waves generated by the Toholu earthquake.  Seismic P-waves are, after all, essentially the same as sound waves.



Scientists at the NOAA Vents Program at Pacific Marine Environmental Laboratory and Oregon State University heard the March 11, 2011 Honshu, Japan earthquake using a hydrophone located near the Aleutian Islands of Alaska.
