HS3M_4M

Fault zone waves: Analytical solutions

Project Description

Author: Yehuda Ben-Zion

Calculates synthetic scalar (P or S) waveforms in a structure with vertical fault zone layers that include body waves and fault zone head and trapped waves. Two codes are included

1. Program "hs3m.f90" corresponds to eq.(2.10) of
   Ben-Zion, Y. and K. Aki, Seismic radiation from an SH line source in a laterally heterogeneous planar fault zone, Bull. Seism. Soc. Am., 80,  971-994, 1990.
2. Program "hs4m.f90" corresponds to eq.(1) of
   Ben-Zion, Y., Properties of seismic fault zone waves and their utility for imaging low velocity structures, J. Geophys. Res., 103, 12567-12585, 1998.

A README file and two example sets of input parameters are included.
