There is a quarry near the dam, he explains and it may have set the whole thing off.

Dr. Leuren Moret says, β€œIt looks to me like the earthquake popped some of the cement tiles up on the spillway in a straight line from the quarry to the spillway where it was first damaged, and that seemed to be in a straight line nearly perpendicular to the spillway.

Earthquake waves are made up of a compression (P) wave (compression expansion), and a sheer (S) wave that moves perpindicular to the direction the wave is travelling. Body waves travel through the earth, and surface waves travel on the surface. In addition to S and P waves there are also Rayleigh waves. They are called ground roll, or surface waves that travel as ripples with motions that are similar to those of waves on the surface of water. There are also Love waves that are horizontally polarized shear waves (SH waves). But whether body or ground waves, they are all called seismic waves.”
