A new tsunami forecasting system, developed with the El Capitan supercomputer, aims to bolster emergency response times in coastal communities during major earthquakes. Conventional systems may provide insufficient warnings, as they rely on simplified models of earthquake characteristics. The new model leverages real-time sensor data and advanced physics modeling to predict tsunami events, allowing for quicker and more accurate alerts. This innovation stems from a collaboration involving several prominent research institutions, reflecting a significant advancement in tsunami early warning technology.
"Conventional tsunami warning systems often rely on seismic and geodetic data to infer earthquake magnitude and location, but typically use simplistic models that fail to capture the complexity of fault ruptures, which can lead to false alarms or dangerously late warnings."
"This framework represents a paradigm shift in how we think about early warning systems," Omar Ghattas, professor of mechanical engineering and principal faculty in the Oden Institute, explained in the post. "For the first time, we can combine real-time sensor data with full-physics modeling and uncertainty quantification - fast enough to make decisions before a tsunami reaches the shore."
