Codes for Calculating Fault Zone Waves
Date: 04/08/2008
Forwarded announcement of a newly available resource from Yehuda Ben-Zion, USC:
The website below has f90 codes that calculate synthetic scalar (P or S) waveforms in a structure with vertical fault zone layers. The waveforms include body waves and fault zone head and trapped waves.
(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.
The website also has two README files and two example sets of input parameters.
You can download the files from:

Best, Yehuda
