Title: Tsunami Science: Studies in early warning and tsunami hazard assessments

Abstract:

Tsunami Science may be divided in two major areas of research, early warning and (long term) tsunami hazard assessments. While the early warning aims to provide a rapid (i.e. ~minutes) and first order estimation of the behavior of a specific tsunami, the tsunami hazard assessments aim to provide an accurate measure of the hazard for future tsunami events. In this talk, I will present some contributions to both research areas. First, I will present the derivation of analytical solutions for the rapid estimation of the near-field runup of tsunamis generated by subduction earthquakes. I will also provide some further details about the response of the tsunami as a function of the earthquake characteristics and some shortcomings of the analytical solutions, regarding to their simplifications. Second, I will show my research regarding to the uncertainty quantification of (long term) tsunami hazard assessments, by following an stochastic approach. I will present an overview of my studies modeling the uncertainties of earthquake characteristics and their propagation to tsunami responses. Then, I will show our new studies assessing the impact of bathymetry data uncertainties in tsunami hazard assessments.
