Abstract:

Probabilistic Tsunami Hazard Assessment (PTHA) performs statistical analysis of tsunami hazards based on a statistical likelihood of earthquake slip distributions. An important component of PTHA is the estimation of such probability distributions based on actual events. Using open-source software package GeoCLAW, we estimate a posterior distribution of a Tsunami event under the Bayesian inference framework, using DART (Deep-ocean Assessment and Reporting of Tsunamis) Buoy data from previous events. We use dimension reduction techniques that allow fast and accurate sampling of the GeoCLAW output for given slip parameters.
