Seismic wave tell how bad the earthquake is. When an earthquake fault ruptures, it causes two types of deformation:
static; and dynamic. Static deformation is the permanent
displacement of the ground due to the event. Typically, someone will build a straight reference line such as a road,
railroad, pole line, or fence line across the fault while it is in the
pre-rupture stressed state. The second type of deformation, dynamic motions, are essentially sound waves
radiated from the earthquake as it ruptures
