**EARTHQUAKE SOUNDS**

Listen to Earthquakes
http://quake.wr.usgs.gov/info/listen/
From the USGS, a collection of earthquake sounds. Hear and download sounds from some recent quakes in California.

Sounds of the Parkfield Earthquake
http://www.cisn.org/special/evt.04.09.28/sounds.html
Hear what a quake sounds like from inside the San Andreas Fault.

Inner Earth, a Seismosonic Symphony
http://www.agnld.uni-potsdam.de/~shw/ABSTRACTS/ScherbaumSeismoSound/InnerEarth.html
What does the earth sound like, and how do we listen to it? Geophysicist Frank Scherbaum and composer Wolfgang Loos paired up to make music from real earthquake sounds. Dr. Scherbaum also has an extensive Web site about the relationship between music and seismology, called The Earth as a Musical Instrument .
