How Physics-Based Earthquake Simulators Might Help Improve Earthquake Forecasts
Conveners: Ned Field and Nick Beeler
Dates: June 18, 2019
Location: Conference Room C, USGS Earthquake Science Center, Menlo Park, California
SCEC Award and Report: 19159
SUMMARY: Due to inevitable assumptions, approximations, and uncertainties, questions have persisted on the usefulness of multi-cycle physic-based earthquake simulators (e.g., RSQSim) with respect to forecasting earthquakes. Whether any model is reliable or trustworthy depends entirely on what questions we are asking of it, so one goal of this workshop is to discuss the specific inferences we would like to make (e.g., as articulated in this recent opinion piece: https://doi.org/10.1785/0220180299). The other goal of the workshop is to identify which of these inferences might be legitimate or robust with respect to current state-of-the-art simulators, as well as what scientific and computational developments will be needed to make such models even more reliable with respect to forecasting earthquakes.
