Seismic Slinky Activity

This activity uses a Slinky to illustrate the different kinds of waves that transmit the energy of an earthquake outward from its focus.This easy activity serves as an introduction to P and S waves and how they transmit a quake's destructive energy from its focus within the earth. You can also demonstrate the action of Rayleigh and Love waves, seismic waves that travel near the surface of the earth.
