Listen To The Acoustic Sound Of The Massive Japan Earthquake
Ever wonder what the fourth-largest recorded earthquake since 1900 sounds like? The Laboratory of Applied Bioacoustics (LAB) has posted the eerie sound online. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC), a network of underground observatories more than a thousand meters below sea level, made the chilling recording as the quake struck.
According to Science Daily, the sounds of Japan's 9.0-magnitude quake "have been accelerated 16 times so that they can be audible to human ears." The red and yellow colors on the spectogram represent the most intense parts of the quake. You can also listen to the first and second aftershock on the LIDO site.
The Laboratory of Applied Bioacoustics (LAB), a unit of the Universitat Politècnica de Catalunya (UPC), directed by Professor Michel André, has recorded the sound of the earthquake that shook Japan on Friday, March 11.
The UPC laboratory is using this platform as part of Listening to the Deep Ocean Environment (LIDO), a LAB-led international project. "LIDO aims, for the first time ever, to record deep-sea sounds in real time and determine how artificial sounds impact the conservation states of the marine environment,"
Some monitoring stations have reported that earthquakes are sometimes preceded by a spike in ULF activity. A remarkable example of this occurred before the 1989 Loma Prieta earthquake in California. On December 9, 2010, geoscientists announced that the DEMETER satellite observed a dramatic increase in ULF radio waves over Haiti in the month before the magnitude 7.0 Mw 2010 earthquake. Researchers are attempting to learn more about this correlation to find out whether this method can be used as part of an early warning system for earthquakes.

The video can be a little misleading. It says the sound was sped up 16 times to make it audible. If you want an accurate reproduction, you would need to slow down the audio 16 times and play through a large infinite baffle array so you can reproduce the frequencies in the single digits. It will be all subsonic vibrations...

I always thought this as well, but that water is traveling fast enough that smashing into something would kill you.
