Sounds of the Sumatra Quake

CNN has posted a news article on how the sounds of the December 2004 Sumatra Earthquake were captured on hydroacoustic microphones run by the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO Preparatory Commission). Of course CNN fails to post a link to this sound file. If I find one, I’ll post it. “It’s really quite an eerie sound to hear the earth ripping apart like that. We hear it on smaller earthquakes quite frequently but something of this scale that goes on for eight minutes is very much unprecedented,” said Maya Tolstoy, a marine geophysicist at Columbia University’s Lamont-Doherty Earth Observatory. Also of note is how these hydroacoustic microphones can possibly be used in the future for earthquake analysis and tsunami warning systems.
