Digital Elevation and Bathymetry Models (DEM) were derived from the USGS 3DEP, and GMRT data, and the maps were produced using the open source Generic Mapping Tools software package. Here, we provide several two-dimensional map-based visualizations of the fault traces and upper tip lines (for blind faults) of the CFM5.3. While the CFM is an inherently three-dimensional subsurface model, users may wish to locate various CFM faults relative to geographic features on a two-dimensional map. GO TO CFM VIEWER Fault Trace Maps of the CFM5.3 The model can be searched/filtered/downloaded based on a number of user criteria. The CFM web-viewer allows users to visualize the CFM in a 2D map-based view, or in a 3D CAD-like environment. To facilitate use of the model, we have created a web-based CFM model viewer which can be accessed at the link below.

See the README.txt file in the root directory of the archive for information about the directory structure and contents of the entire zipped archive.Äownload the complete CFM5 archive (ZIP, 64MB) CFM5.3 Web Viewer and Query Tool Additionally, the expanded metadata includes fields the equivalent USGS Quaternary fault (Qfault) ID, when available. The expanded metadata now includes fault surface areas, area-weighted average strike/dip values, expected sense of slip, and references for each fault object. CFM fault objects follow a hierarchical naming system that enables model users to easily sort the model by region and subregions. Automated scripts now check for consistency with filenames and the various metadata components. In addition, the new model has greatly expanded and improved the metadata component of CFM to help ensure the internal consistency and maintainability of the model. Current Model Version: CFM5.3 The latest release of the CFM is version 5.3, which includes many new and revised fault representations, notably in the Ridgecrest and offshore regions (Plesch et al.

Together with the Community Velocity Model (CVM-H 15.1.0), the CFM comprises SCEC's Unified Structural Representation of the Southern California crust and upper mantle (Shaw et al., 2015). The CFM serves the Southern California Earthquake Center (SCEC) as a unified resource for physics-based fault systems modeling, strong ground-motion prediction, and probabilistic seismic hazards assessment (e.g., UCERF3). The CFM faults are defined based on all available data including surface traces, seismicity, seismic reflection profiles, well data, geologic cross sections, and various other types of data and models. For the preferred fault set (440 surfaces), each fault object consists of triangulated surface representations (t-surfs) in several resolutions, fault traces in several different file formats, and complete metadata including references used to constrain the surfaces. Including alternative representations, the model incorporates 1186 objects. The SCEC Community Fault Model (CFM) is an object-oriented, three-dimensional representation of active faults in southern California and adjacent offshore basins that currently includes 440 individually named fault representations in the preferred model.
