AXITRA Code Discussion

This section of the website is designed for wiki-style discussion between SIV participants. To make changes and add comments, once you are logged in, click "edit" in the "This Page" pane to the left.

This space can be used to facilitate bringing the Green's function codes into agreement & helping present and future modelers set up & run the codes correctly.

Summary of AXITRA code

• discrete wavenumber method, Bouchon 1981
• Kennett (1979) propagator matrix technique

Code developed by:

Current modelers:

Submitted Green's function results using AXITRA:

Problems with Green's function computation / Help for Modelers:

• time shifts -- AXITRA centers origin time at the peak of the source time function
• near-fault y-component messed up in some AXITRA submissions (non-convergence of wavenumber summation?)
• What general guidelines can users of the code use to calculate waveforms to a given frequency?
• different versions of AXITRA that are being used
