Fig 1: Broadband Platform.

The SCEC Broadband Platform is a software system which generates 0-100 Hz seismograms for historical and scenario earthquakes in California, Eastern North America, and Japan.

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 was implemented using software development best practices, including version control, user documentation, acceptance tests, and formal releases, with the aim of ease of installation and use.

Current Release

The current official release of Broadband Platform is v15.3.0. This is a new version of the platform that includes a large number of new capabilities. It is the first major release of the Broadband Platform since version 14.3.0, released in March 2014. Details of the new features along with several bugs fixes are provided in the release notes and the "changes" section below. New, and old Broadband platform users should work with this version of the software, and we recommend current Broadband platform users migrate to this new version whenever possible.

Dependencies

Broadband has the following dependencies:

Please refer to the Broadband User Guide v15.3.0 for more details about the specific versions required for each of the packages above. This version of the Broadband Platform does NOT require Intel compilers.

Documentation Including Installation Instructions

User Guide Wiki (includes installation instructions):

Installation Overview

This section provides a brief overview of how the Broadband Platform can be installed on your local Linux or Mac OS X computer. There are additional, more detailed, installation instructions in the Broadband User Guide v15.3.0.

Briefly, BBP installation can be summarized in the following steps:

The software can be installed in an account on a Linux or Mac OS X computer with at least 10GB of disk storage and C, Fortran, and Python software installed.
From the Linux/Mac computer, start a web browser and point to this download page. Alternatively, you can download the files to a different machine and use FTP or SFTP to copy them over.
After downloading each file, run the md5sum program to confirm you have an undamaged version of the distribution files by comparing the md5sum provided in the .md5 files against the one calculated at the local computer.
Uncompress the distribution (tar.gz) files into the proper directory structure as described in the Broadband User Guide v15.3.0.
Build the executables by running the top level makefile.
Configure your environment by adding a few Broadband Platform variables to your shell's environment.
Confirm the code is built correctly by running UnitTests.
Confirm the code runs correctly on your system by running AcceptanceTests.
Use the platform for research purposes.

Current Broadband Platform Release Downloads

The current SCEC Broadband platform release is v15.3.0. Links to the source distribution and Green's Functions and Validation packages are listed in the table below:

To install and use the Broadband platform, you need the source code, one or more Green's Functions packages, and optionally one or more Validation packages. The Broadband Platform contains cumulative improvements to the geoscientific codes and software infrastructure. We recommend use of the most recent version of the Broadband Platform, unless you are trying to reproduce results generated with an earlier version of the platform.

-== Description ==
-The SCEC Broadband Platform (BBP) (Phase 1, June 2013 and March 2014) has been developed and released as open-source scientific software that can generate broadband (0-100Hz) ground motions for earthquakes, integrating complex scientific modules that implement rupture generation, low and high-frequency seismogram synthesis, non-linear site effects calculation, and visualization into a software system that supports easy on-demand computation of seismograms. The BBP has been developed by a scientific and engineering collaboration that involves geoscientists, civil engineers, graduate students, and scientific software developers. The SCEC BBP operates in two modes: validation simulations and scenario simulations. In validation mode, the BBP runs earthquake rupture and wave propagation modeling software to calculate seismograms of a historical earthquake for which observed strong ground motion data is available. Here, the BBP calculates a number of goodness of fit (GOF) measurements that quantify how well the model-based broadband seismograms match the observed seismograms. Based on these results, the BBP can be used to evaluate and validate different numerical ground motion modeling techniques. The BBP currently accommodates validation simulation inputs and observational data for 12 historical events from the eastern and western United States, eastern north America, and Japan. In scenario mode, the user specifies an earthquake description, a list of station names and locations, and a 1D velocity model for the region of interest simulations for hypothetical earthquakes, and the BBP software then calculates ground motions for the specified stations.
