The SCEC Community Fault Model (CFM) is an object-oriented, three-dimensional representation of active faults in southern California and adjacent offshore basins that includes 105 complex fault systems (Plesch et al., 2016; Nicholson et al., 2017) composed from more than 380 individually named fault representations. The model incorporates more than 820 objects, which include triangulated surface representations (GOCAD t-surfs) and associated metadata. The CFM 3D faults are defined based on surfaces traces, seismicity, seismic reflection profiles, wells, geologic cross sections, and various other types of models. 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. The latest release of the CFM is version 5.2 which includes many new and revised fault representations (Nicholson et al., 2017, 2018). In past years, the SCEC CFM has been distributed as a collection of files, including fault information and metadata in an Excel spreadsheet, and fault geometry files in 2D GIS shapefile and 3D GOCAD t-surf formats. To make the CFM more accessible and useful to researchers, we are developing a web-based interface to the CFM. Our current prototype CFM website provides a map-based interface to the CFM model, and it enables users to view and download the CFM 5.2 faults and fault metadata. The current site also allows users to download CFM fault geometry files in user-selected format and resolution. SCEC’s science and software groups are developing the CFM website using an iterative software development process in which SCEC scientists identify and prioritize desired capabilities, the SCEC software group rapidly prototypes new features, and SCEC researchers review the site capabilities to ensure they provide value and ease of access to the science community.
