"The are many different seismic waves, but all of basically of four types:
Compressional or P (for primary) or S (for secondary) Love Rayleigh An earthquake radiates P and S waves in all directions and the interaction of the P and S waves with Earth's surface and shallow structure produces surface waves."
Work is force times distance. If you push on an object really hard but it does not budge, you have still performed no work on it, because anything times zero is still zero.
