— returns Earth's physical parameters for a given depth profile (Matlab).
— calculates mineral and aggregate elastic parameters at given pressures and temperatures (Matlab).
— solves 3-D tomographic problems with singular value decomposition (Matlab and C).
— calculates 2-D and 3-D finite difference wavefields for fully anisotropic media (Matlab).
8-26-08 Minor efficiency improvements, added anelasticity and ability to solve 1-D problems.
— beach-ball diagram of earthquake focal mechanism(s) (Matlab).
3-28-08 Input can now either be strike dip and rake or the six independent moment tensors
USGS Hazard Codes
— official USGS hazard codes used for the 1996 national seismic hazard maps (Fortran90 for SunOS).
— an interactive application allowing the user to evaluate various
elements of probabilistic seismic hazard assessment (Java).
— shifts 1-D series (Matlab).
— generates gaussian series (Matlab).
— generates a gaussian surface (Matlab).
— filters series by convolution with a gaussian (Matlab).
