tware system that provides user-defined, repeatable calculation of ground-motion seismograms, using alternative simulation methods, and software utilities to generate tables, plots, and maps. The BBP has been developed over the last eleven years as a collaborative project involving researchers, graduate students and practitioners from seismology and earthquake engineering, and the SCEC research computing group.
The Broadband Platform is distributed as an open-source software that can be compiled and run on recent Linux systems with GNU compilers. The BBP distribution includes seven simulation methods, ten simulation regions covering California, Japan, Central Italy, Central and Eastern North America, and the ability to compare simulation results against empirical ground motion models. Recent developments to the BBP include significant improvements to several simulation methods, the ability to simulate multi-segment ruptures, and the addition of a validation module based on Fourier Amplitude Spectra, in addition to the previously implemented Pseudo-Spectral Acceleration Spectra metrics needed for engineering applications. This will allow better seismological interpretations of the simulation results. This presentation will cover various BBP capabilities and focus on initial FAS-based results from various validation events in several California regions.
