SCEC Software
The Southern California Earthquake Center develops, maintains, and supports a number of scientific software programs. All SCEC-supported software distributions are available through this software download page.
CVM-H
The CVM-H is a velocity model of crust and upper mantle structure in southern California developed by the SCEC community for use in fault systems analysis, strong ground motion prediction, and earthquake hazards assessment. The model describes seismic P- and S-wave velocities and densities, and is comprised of basin structures embedded in tomographic and teleseismic crust and upper mantle models.
Broadband Platform
The goal of the SCEC Broadband Simulation Platform is to generate ground motions for a particular earthquake scenario using deterministic low-frequency and stochastic high-frequency simulations. It provides multiple approaches for generating the rupture description, modeling high- and low-frequency wave propagation, and incorporating site amplification effects. These codes have been validated against recorded ground motions from real events, to increase confidence in their results. With the Broadband Platform, a user can select which combination of approaches to use and simulate an earthquake, producing seismograms which include high and low frequency data. Ultimately these seismograms can be used to improve ground motion attenuation models, resulting in more accurate predictions of future ground motions for building engineers.
