Project Abstract
The goal of this project was to convert the SCEC Community Fault Model (CFM) into a form that is ac-cessible for use by earthquake simulators. The conversion turned out to be much more difficult than we expected, for two primary reasons:
(a). The CFM does not contain slip rates or rake angles, which are essential for constructing the simulator input files. So slip rates and rake angles must be obtained from other sources.
(b). The CFM contains surface topography, which must somehow be removed because simulators require the earth’s surface to be flat.
We made substantial progress in addressing both of these major difficulties, as described in this report. We also addressed several more minor difficulties.
In the end, we succeeded in generating a simulator input file containing the same triangular fault elements as a large part of the CFM. There are several existing earthquake simulator codes that could use this input file. However, there are still issues that need to be addressed, and so in our judgment the result is not yet ready for publication.
Intellectual Merit The goal is to increase the usefulness of SCEC-funded research, by converting the SCEC Community Fault Model into a form that can be used in numerical simulations performed by earthquake simulators.
Broader Impacts The potential benefit is to allow earthquake simulators to use more accurate fault models, which exist but have not been readily accessible.
