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 ten years as a collaborative project involving geoscientists, earthquake engineers, including graduate students, researchers and practitioners, and the SCEC research computing group.
The Broadband Platform is distributed as 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 improvements to the BBP include the ability to simulate multi-segment ruptures using most simulation methods, and the addition of a site effects module that models site-specific non-linear response to strong ground motions. There are also significant improvements to several simulation methods, a new Vs30 goodness-of-fit plot, and the addition of two new simulation regions covering Central Italy and the Southern Walker Lane region, where the Ridgecrest 2019 earthquake sequence was located.
