Fast Tsunami Simulations for a Real-Time Emergency Response Flow
TimeFriday, 13 November 20204:15pm - 4:40pm EST
DescriptionIn the context of response to disasters, fast and accurate simulations can be integrated into a real-time flow, allowing best situation estimates to be provided at required deadlines for warnings and decisions. In such a pilot centered on earthquakes, the TsunAWI tsunami simulation code has been adapted and improved to provide both fast results and accurate results. Improvements to the TsunAWI code are providing better performance and the needed accuracy with reduced computer resources, and opening possibilities for handling early event source uncertainties. Heuristics for mesh traversal ordering are bringing performance improvements, and validation against historical cases show that the required accuracy is attained.
