Recording of Deadly Indonesian Earthquake

Sound from last December's huge tsunami-causing earthquake was picked up by underwater microphones designed to listen for nuclear explosions.

Scientists this week released an audio file of the frighteningly long-lasting cracks and splits along the Sumatra-Andaman Fault in the Indian Ocean. The recording of the quake starts out silent. A low hiss begins and the intensity builds gradually [in] a rumbling crescendo. Then it tails off but, frighteningly, builds again in waves as Earth continues to tremble.

The audio file here ( 050722_earthquake_sound.html) is sped up 10 times to make it easier to hear.

The recorded data was provided in March to scientists by the International Monitoring System of the Comprehensive Nuclear Test Ban Treaty. An analysis of the data is detailed in the July/August edition of the journal Seismological Research Letters.

Maya Tolstoy of Columbia University's Lamont-Doherty Earth Observatory and her colleague, DelWayne Bohnenstiehl, converted the data to make the new audio file - MP3 file at this link: 2005/images/tsun_eq.mp3

In other sound-related news, on Monday 25th July, 2005, Gut Records will release a U.K. album of Crazy Frog mixes, Crazy Frog Presents Crazy Hits, featuring new mixes of old hits including Technotronic's Pump Up the Jam. This may spawn a new cohort of ringtones to charm and beguile the populace
