How can one prove or show that seismic waves produced by the earth during an
earthquake consists of transverse and longitudinal waves?
Seismometers are sensitive instruments that measure the direction of motion of the
surface of the earth. They are able to distinguish "up / down", "back / forth", "left /
right" directions of motion of the earth. By resolving the complex motions of the earth's
surface into these components they are able to tell transverse vs. longitudinal waves.
