Recording the Sound Made by the 9.0 Magnitude Earthquake In Japan

It’s a strange thing to say, but they could hear Japan’s 9.0 magnitude earthquake in Alaska. At least Oregon State University scientists could, using the U.S. Navy’s SOund SUrveillance System (SOSUS) Monitoring System, previously intended for tracking submarines in the Cold War. The recording is now online and it is an awe-inspiring sound.

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.
