Probabilistic Source Selection for the Cascadia Subduction Zone

Abstract

This report has been submitted to FEMA Region IX as a final project report for a project on developing new methodologies for Probabilistic Tsunami Hazard Assessment (PTHA). 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.
