"Tsunami Sands Enhance Accuracy of Cascadia Earthquake Models"
Scientists have used sediment cores and the Delft3D-FLOW model to test various earthquake models of the 1700 Cascadia event, finding that the earthquake likely caused at least 0.8 meters of subsidence and about 12 meters of fault slip. This study provides new constraints on the earthquake's size and offers insights into using tsunami deposit mapping and sediment transport models to better understand past and future seismic events.
