PRISM software: Processing and Review Interface for Strong Motion Data

PRISM is designed to be used for automatically processing raw strong-motion acceleration time series to produce compatible acceleration, velocity and displacement time series, acceleration, velocity and displacement response spectra, Fourier amplitude spectra, and standard earthquake-engineering intensity measures.

Slick Package

The slick package uses fault slip data (either field observations or from focal mechamism) to find the stress tensor that best explains the observations. Inputs are the orientation and slip direction of a set of fault planes.
