    The model inventory and design specifications were established by a CFM working group, which included representatives from the model's planned users (e.g., RELM project), from related database efforts (e.g. CGS, SCFAD), and SCEC's IT program. The object-oriented, CAD-based model provides three-dimensional representations of major strike-slip, blind-thrust, and reverse faults in a precise geographic reference frame (latitudes from 32.5 degrees N to 36 degrees N, longitudes from 114.5 degrees W to 120.5 degrees W). Each fault is currently represented by a triangulated surface in ASCII format (here), with regularly gridded surfaces to be provided soon.

    The model represents a list of "preferred" representations that are extracted from a relational database, which is searchable by users via a web-interface. The database contains a unique naming and numbering system for each fault (based on the CGS system), as well a various attributes including the fault type, slip rate (from CGS and SCFAD), uncertainties, quality of representation, and key references. Most faults have distinct interpolated and extrapolated segments, and many have alternative representations. The coordinate system of the fault data is the UTM projection at zone 11, datum NAD 1927 (Implies geoide Clark 1866)
