Seismology, Earth Structure



I am interested in understanding Earth structure from the surface to the center.
It requires understanding of how seismic waves propagate in the interior, the higher frequency end
being heavily scattered, messy waves above 1 Hz and the lower frequency end being
the ringings of the whole Earth around 1000 seconds.
