Yoshiki Yamazaki, Ph.D. Post-doctoral Research Fellow Department of Ocean and Resources Engineering The low-lying coastal communities of Hawaii are vulnerable to flooding from tsunamis and hurricanes. In particular, Hawaii was hit by six destructive tsunamis generated by subduction earthquakes during the last 100 years. Accurate prediction of tsunami impacts is crucial for mitigation planning and emergency response. We have developed the shock-capturing, dispersive wave model, NEOWAVE (Non-hydrostatic Evolution of Ocean WAVEs), which includes a two-way nesting scheme of telescopic grids to describe tsunami generation, propagation, and inundation in a single computation. The main motivation for the development is to have
