This animation uses a gridded
sphere is to show a single
station recording five equidistant
earthquakes. For demonstration,
we are assuming that each
earthquake is about a magnitude 7
and the seismic waves are traveling
through similar material, thus the
seismograms are all the same.
All the seismologist would know
about any of the earthquakes is
that they occurred somewhere on
the dashed circle in the last frame.
