Rapidly available and accurate ground-motion acceleration time series (seismic recordings) and derived data products are fundamental to quickly providing scientific and engineering analysis and advice after an earthquake. To meet this need,the U.
S. Geological Survey National Strong Motion Project has developed a software package called PRISM (Processing and Review Interface for Strong-Motion data). PRISM automatically processes strong-motion acceleration records, producing compatible acceleration, or velocity,and displacement time series; acceleration, velocity, and displacement response spectra; Fourier amplitude spectra; and standard earthquake-intensity measures. PRISM is intended to be used by strong-motion seismic networks,as well as by earthquake engineers and seismologists.
