Wavemod

WaveMod calculates synthetic waveforms using various tools. Three main classes are currently available:

• WaveDB deals with synthetic waveforms computed from Green's function database.
• WaveInt is a wrapper of Bob Hermann's Wavenumber Integration code.
• FastSweep is a simple 2D eikonal solver used for rupture front propagation on simple faults.

Some instructions

• The WaveMod module must be located in a directory that is incuded in the PYTHONPATH environment.
• To use WaveDB, Green's function databases must be organized following the W-phase format. We use SAC files stored in sub-directories as follows: H????.?/??/GF.????.SY.LH?.SAC where
  • H????.? indicates depth (in km)
  • /??/ indicates the moment tensor component (PP,RP,RR,RT,TP,TT)
  • ????.SY is the epicentral distance x 10 (in km or deg)
  • LH? is the component (either LHL or LHZ)
• SAC files are handled using the sacpy module available at https://github.com/eost/sacpy
• To use WaveInt, the package "Computer programs in seismology" must be installed and path to associated binaries must be included in the PATH environment variable : http://www.eas.slu.edu/eqc/eqccps.html
