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, 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 current official release of Broadband Platform is v13.9.0. This distribution was posted online on Thursday, 26 September 2013. 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 11.2.3, released in May 2012. 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.

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.

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 v14.3.0. 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 13.9.0, released in September 2013. 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 v14.3.0 for more details about the specific versions required for each of the packages above. A non-commercial copy of Intel C and FORTRAN compilers can be obtained by registering for a non-commercial account with Intel and downloading the compilers from the Intel website.

Downloads

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.

Users that are upgrading from previous version of the Broadband Platform will need to retrieve new versions of all the Broadband Platform packages as there have been significant changes in all the packages since the previous 13.9.0 release.

There are detailed installation instructions in the Broadband User Guide v14.3.0.

Detailed instructions to setup the Broadband Platform as a local installation on a Linux Machine are provided in the Broadband User Guide v14.3.0. Briefly, they can be summarized in the following steps:

  1. The software can be installed in an account on a Linux computer with at least 10GB of disk storage and C, Fortran, and Python software installed.
  2. From this Linux 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.
  3. Download each file into a directory and run the md5sum program to confirm you have an undamaged version of the distribution files by comparing the md5sum provided below against the one calculated at the local Linux computer.
  4. Uncompress the distribution (tar.gz) files into the proper directory structure as described in the Broadband User Guide v14.3.0.
  5. Build the executables by running the top level makefile.
  6. Configure your environment by adding a few Broadband Platform variables to your shell's environment.
  7. Confirm the code is built correctly by running UnitTests.
  8. Confirm the code runs correctly on your system by running AcceptanceTests.
  9. Use the platform for research purposes.
