Mathematical science models help predict the timing and trajectory of tsunami waves based on ocean floor mappings and ocean tide gauge readings. This information is used to predict when tsunami waves will hit different coasts. *Deep Ocean Assessment and Reporting of Tsunamis
High-resolution computational models are used to simulate wave-heights for a traveling tsunami, shown here for two different earthquakes. These estimates help to identify evacuation zones and routes. The impacts of tsunamis vary widely, due to local topography, long-term sea level rise, annual climate variability, monthly tidal cycles, and short-term meteorological events.
