We propose a methodology for taking a large number of realizations of potential future earthquakes (with associated probabilities) and producing good approximations to the resulting hazard curves and maps without doing a computationally- expensive fine-grid tsunami simulation for each realization.en-USAttribution 3.0 United Stateshttp://creativecommons.org/licenses/by/3.0/us/tsunami hazard analysisGeoClawTechnical Report
