4 Station Seismic Network with No Wave Paths

This animation shows the amplified ground motions as the
seismic waves arrive at each seismic station,
but does not show the paths the waves follow
through the Earth. The purpose is to have
students observe the ground motions and
seismograms and infer where the earthquake
occurred using the amplitudes and arrival times
of the seismic waves at the four stations. A
leading questions might be: Why does Station
D only experience two waves, the up-down
motion from the first seismic wave and rolling
motion from the last wave and not the back-
and-forth ground motion from a second wave
like the other stations?
