6. The best way to determine how strain accumulates in a fault is with GPS measurements of plate motion. As ground on each side of a fault moves, the potential energy that accumulates in a fault can be estimated and used to forecast the rough timing, magnitude, and location of an earthquake.
7.When seismic waves travel through the earth, they refract along different directions, creating seismic shadow zones. The size and distribution of seismic shadow zones can be used to determine whether different layers are solid or liquid as well as the size of each layer.
