Tsunami Squares: Earthquake driven inundation mapping and validation by comparison to the Regional Ocean Modeling System

A promising tsunami warning system outlined here links Total Electron Content (TEC) disturbances in the ionosphere detected by GNSS satellites to maps of inundated areas along the affected coastlines. This will be accomplished through a pipeline of earthquake, ionosphere, and tsunami simulations. Th...
