What are surface waves?
Move more slowly than p waves and S waves but they can produce severe ground movements
300
What is the moment magnitude scale?
A rating system the estimates the total energy released by an earthquake.
400
Uses satellite systems to measure changes in elevation and tilt of the land as well as horizontal movement along a fault
