Question:
I am looking for a seismogram that has the Earth's free
oscillation frequency period indicated on it. Please help.
Replies:
This is not an easy question because the earth is not a homogeneous body,
and different seismic vibration types and sources all travel at different
speeds and have different "fingerprints". I believe there is some discussion
of seismic activity in either Scientific American or Discover magazine in
the last month or two.
If you search on the engine www.google.com terms "seismic vibrations earth"
you will find a number of sites that deal with your question at differing
levels of sophistication.
