Acoustic Manifestation of Earthquakes:
high-resolution views, please click on the images.
can detect earthquakes (among other things!) through various methods.
Among others, ocoustic signals are interesting tools to study seismic
(or otherwise?!) sources.
I am working on a software package to automate tsunami warning based on
T-wave detection at seismic stations in the Pacific. Many factors have
to be taken into account, including (but not limted to)
seismic-acoustic & acoustic-seismic conversions at source and
receiver sides, SOFAR parameters in the propagation medium and path
parameters at source & receiver sides. The fun part is that, in
this approach, you don't really need to have a reliable source geometry.
T-Wave acoustic paths for the selected stations in the Pacific.
2. Pressure Signals:
An interesting part of my research is working on the pressure signals
from OBS hydrophones in search for a quantifiable measure of
tsunamigenic character of earthquake. We are still searching ... :)
