Source characteristics of these earthquakes were studied using the teleseismic body waves recorded at the IRIS Global Seismographic Network.

Working with the Melbourne sound artist Malcolm Riddich, she transformed these sounds of aftershocks and chaos into a soundscape called Body Waves
As a result, an explosion tends initially to radiate mostly compressional or P (for primary, since P waves arrive at seismic stations before other body waves
) body waves
, which produce an upward and outward motion at the earth's surface.
The seismic waves produced by earthquakes include body waves
which travel through the earth and surface waves which travel across it.
This is because the underlying geology of the two regions is quite different, and the body waves
-- seismic signals that travel down through the mantle and crust -- are affected by this geology.
