Coupled simulation of ground shaking and tsunami for mega-thrust subduction earthquakes

International Conference on Applications of Statistics and Probability (12th : 2015 : Vancouver, B.C.)

A novel framework for concurrently simulating strong motions and tsunami waves is developed. It explicitly considers the dependency of both hazard processes on common source characteristics. The earthquake source properties are modeled stochastically, incorporating various sources of uncertainties. The developed computational procedure is applied to the Mw9 2011 Tohoku, Japan earthquake. Numerical examples of the coupled simulations of strong motion and tsunami highlight the major impact of source characteristics on strong motion and tsunami hazard parameters. The investigations also provide valuable insights in understanding the spatial impact of cascading earthquake hazards. Such an advanced numerical tool is necessary for assessing the performance of buildings and coastal infrastructure that are subjected to cascading hazards triggered by large subduction earthquakes.
