== Overview ==
 
 
 
The goal of the SCEC Broadband Simulation Platform is to generate broadband (0-100 Hz) ground motions for earthquakes. The SCEC Broadband Platform is a collaborative software development project involving SCEC researchers, research engineers, graduate students, and the SCEC/CME software development group. SCEC scientific groups have contributed modules to the Broadband Platform including rupture generation, low- and high-frequency seismogram synthesis, non-linear site effects, and visualization. These complex scientific codes have been integrated into a system that supports easy on-demand computation of broadband seismograms.  The SCEC Broadband Platform is designed to be used by both scientific and engineering researchers with some experience interpreting ground motion simulations.
 
 
 
Users may calculate broadband seismograms for both historical earthquakes (validation events including Northridge and Loma Prieta) and user-defined earthquakes. The platform produces a variety of data products, including broadband seismograms, rupture visualizations, and several goodness-of-fit plots.  Users can install the platform on their own machine, verify that it is installed correctly, and run their own simulations on demand without requiring knowledge of any of the code involved. Users may run a validation event, supply their own simple source description, or provide a rupture description in SRF format. Users may specify their own list of stations or use a provided list. Currently the platform supports stations and events in Southern California, the Bay Area, the Mojave Desert, Eastern United States, Eastern Canada, Central and Western Japan. Users may select among various method that include rupture generation, low-frequency synthesis, high-frequency synthesis, and incorporation of site effects, with the option of running a goodness-of-fit comparison against observed or simulated seismograms.  These codes have been validated against recorded ground motions from real events.
 
 
 
The Broadband Platform software development is performed using modern software engineering practices, including version control, user documentation, acceptance tests, and formal releases, with the aim of accuracy, reliability, ease of installation and use.

This version was released in May 2022. BBP v22.4 includes several new capabilities. Details of the new features and capabilities of BBP v22.4 are described in the [https://github.com/SCECcode/BBP/wiki/Release-Notes BBP v22.4 release notes]. We recommend that all new users work with BBP v22.4 because this version adds new capabilities and improvements to the methods provided in earlier releases of the Broadband Platform. We recommend existing Broadband platform users migrate to BBP v22.4 whenever possible. Previous versions of the Broadband Platform will remain available for users that want to reproduce results produced with earlier versions of the Platform. Please review the [https://github.com/SCECcode/BBP/wiki/Installation BBP installation instructions] for details on how to download and install BBP v22.4 on your local computer.

The SCEC Broadband Platform is a collaborative software development project involving SCEC researchers, research engineers, graduate students, and the SCEC/CME software development group. SCEC scientific groups have contributed modules to the Broadband Platform including kinematic rupture generation, low- and high-frequency seismogram synthesis using 3D wave propagation through 1D layered velocity structures, non-linear site effects, ground motion intensity measure calculations, and visualization. These complex scientific codes have been integrated into a system that supports easy on-demand computation of broadband seismograms, providing user-defined, repeatable calculation of ground-motion seismograms, using alternative simulation methods, and software utilities to generate tables, plots, and maps. The SCEC Broadband Platform is designed to be used by both scientific and engineering researchers with some experience interpreting ground motion simulations.

The SCEC BBP software can be compiled and run on recent Linux systems with GNU compilers. The Broadband Platform continues to evolve, and new versions of the BBP are released periodically on GitHub. The latest release includes seven simulation methods, eight simulation regions covering California, Japan, Eastern North America, and the ability to compare simulation results against empirical ground motion models. The newest features include the ability to simulate multi-segment ruptures using several simulation methods. And, in addition to a new simulation method, it now includes improvements to several existing ground motion simulation methods and revised Green’s functions for all simulation regions. In this release, the site response module is integrated with all simulation methods and can also be used for comparing simulated data against historical earthquakes

Fig 1: Broadband Platform showing ground motion simulation methods (blue circles), and optional post-processing methods (green circles).

The Southern California Earthquake Center (SCEC) Broadband Platform (BBP) is a software system that can generate 0-20+ Hz seismograms for historical and scenario earthquakes in California, Eastern North America, and Japan using several alternative computational methods.

Current Release

The current release of the SCEC Broadband Platform software is available for download from:

This version was released in May 2022. BBP v22.4 includes several new capabilities. Details of the new features and capabilities of BBP v22.4 are described in the BBP v22.4 release notes. We recommend that all new users work with BBP v22.4 because this version adds new capabilities and improvements to the methods provided in earlier releases of the Broadband Platform. We recommend existing Broadband platform users migrate to BBP v22.4 whenever possible. Previous versions of the Broadband Platform will remain available for users that want to reproduce results produced with earlier versions of the Platform. Please review the BBP installation instructions for details on how to download and install BBP v22.4 on your local computer.

Overview

The goal of the SCEC Broadband Simulation Platform is to generate broadband (0-20+ Hz) ground motions for earthquakes. The SCEC Broadband Platform is a collaborative software development project involving SCEC researchers, research engineers, graduate students, and the SCEC/CME software development group. SCEC scientific groups have contributed modules to the Broadband Platform including kinematic rupture generation, low- and high-frequency seismogram synthesis using 3D wave propagation through 1D layered velocity structures, non-linear site effects, ground motion intensity measure calculations, and visualization. These complex scientific codes have been integrated into a system that supports easy on-demand computation of broadband seismograms, providing user-defined, repeatable calculation of ground-motion seismograms, using alternative simulation methods, and software utilities to generate tables, plots, and maps. The SCEC Broadband Platform is designed to be used by both scientific and engineering researchers with some experience interpreting ground motion simulations.

Users may calculate broadband seismograms for both historical earthquakes (validation events including Northridge, Loma Prieta, etc.) and user-defined earthquakes. The platform produces a variety of data products, including broadband seismograms, rupture visualizations, and several goodness-of-fit plots. When running a validation event, users supply their own simple source description, or provide a rupture description in SRF format. Users may specify their own list of stations or use a provided list.

The SCEC BBP software can be compiled and run on recent Linux systems with GNU compilers. The Broadband Platform continues to evolve, and new versions of the BBP are released periodically on GitHub. The latest release includes seven simulation methods, eight simulation regions covering California, Japan, Eastern North America, and the ability to compare simulation results against empirical ground motion models. The newest features include the ability to simulate multi-segment ruptures using several simulation methods. And, in addition to a new simulation method, it now includes improvements to several existing ground motion simulation methods and revised Green’s functions for all simulation regions. In this release, the site response module is integrated with all simulation methods and can also be used for comparing simulated data against historical earthquakes

The Broadband Platform is open-source software that is made available under the terms of the BSD-3 License. A copy of the License can be found with the software in the 'LICENSE' file in the GitHub repository.
