==== Week 2/2 ====

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.

Fig 1: The SCEC Broadband Platform scientific software modules can be combined to implement earthquake simulations that produce ground motion time series.

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.
