The reduction of peak velocities in our models caused by mostly shallow, near-fault nonlinear effects may 4.1.1 Near-Fault Effects Ground motions close to a ruptured fault can be significantly different than those further away from the seismic source. The near-fault zone is typically assumed to be within a distance of about 20-60 km from a ruptured fault. Within this near-fault zone, ground motions are
