Abstract:
Researchers from the Southern California Earthquake Center (SCEC) are developing and integrating a collection of community models that describe a wide range of features of the southern California lithosphere and asthenosphere. The geophysical properties defined by these models, collectively referred to as the SCEC CXM models, include elastic and seismic attenuation properties (Community Velocity Model, CVM), large-scale crustal blocks represented by the tectono-stratigraphic terranes (Geological Framework Model, GFM), temperature (Community Thermal Model, CTM), rheology (Community Rheology Model, CRM), stress and stressing rate (Community Stress Model, CSM), deformation rate (Community Geodetic Model, CGM), and fault geometry (Community Fault Model, CFM). The ultimate long-term goal of the CXM research group is to provide an internally consistent suite of models that can be used together to simulate deformation and seismic phenomena in southern California.
Over the past year, we have developed and refined several web-based interfaces to the SCEC CXM models. The CFM web viewer now provides surface map and 3D views of CFM fault geometries and supports searches by name and region, with downloading of selected fault geometries in multiple formats and resolutions. We have developed a prototype GFM/CTM web viewer that can query these models and return geological region, lithology type, and temperature for user specified points. Multiple CXM models are integrated in a SCEC Community Models Viewer (SCMV) that presents users with options to view the SCEC CVM, CFM, GFM, and CTM models. The SCEC Community Models Viewer helps to show the relationship and consistency between these models in ways not possible when viewing the models individually and will greatly facilitate use of these community products.
