Hi Meredith,

Interesting article. A few months ago a chap contacted me,  who is working on a
"Phd" on 3D sound  modelling? . Anyhow, he wanted a months worth of
seismic data, which I sent him. After a few weeks he sent me the same
data that was turned into a "Wave" file. When I played the "CD" it was
amazing to hear the seismic events and background noise. The big quakes
sound like thunder with pop's and clicks. I identified some of these as "PcS"
waves. Its amazing. The earth is worth listening too .
