Project Abstract
 The purpose of this workshop was to discuss some problems in using the CFM faults as input to Earthquake Simulators and potential solutions to these problems. The hope was that from this workshop would emerge a consensus as to the best way to solve these problems, a team of individuals who will agree to do collaborate via one or more SCEC proposals to do the required work, and to develop an approach so that once an initial CFM-EQSIM is created it can easily be updated as improvements are made to the CFM. The workshop was quite successful. Interesting ideas were presented by many of the participants which provide potential solutions for the problems discussed. Several of the participants discussed a plan to test one of these potential solutions, and are joining in a proposal to do this.
Intellectual Merit It paves the way for the most accurate fault description available to be used by earthquake simulators in creating simulated earthquake catalogs. Using the detailed fault description in the CFM would allow these catalogues to extend down to smaller magnitude earthquakes than is now possible using only faults in the UCERF3 fault model. This would allow more meaningful statistical comparison between the simulated and real catalogs due to the much more frequent occurrence of smaller earthquakes. Such comparisons are important in testing the results of earthquake simulators.
Broader Impacts It will open the way for more meaningful future simulations of earthquakes. This will create research opportunities for many SCEC scientists of all ethnicities and at all stages of their research careers to work on such problems. It also benefits society by providing the public with better understanding of the timing, location, and size of future damaging earthquakes and generally supports the increasing use of earthquake simulators in developing further versions of UCERF.
