This Project Grant from the National Science Foundation Division of Earth Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $355,358 to San Diego State University Research Foundation to develop a fully-coupled model of dynamic rupture, wedge plasticity, and tsunami for great earthquakes in the Japan Trench. Specifically, the awardee will (1) develop a dynamic rupture model of the 2011 Tohoku earthquake that can explain key observations, (2) simulate prior Sanriku earthquakes to investigate sensitivities of acoustic waves and tsunami to shallow slip and wedge plasticity, and (3) identify acoustic waves that could improve next-generation tsunami early warning systems globally. This three-year award period beginning February 1, 2023 supports research that furthers understanding of megathrust and outer-rise faulting earthquakes and their tsunami generation through sophisticated computer modeling, with potential to enhance tsunami warnings.
