Immediately following a major underwater quake, the water may pull away from the coast—a phenomenon known as drawback—before returning as a series of massive waves.
Scientists use the "seismic gap" theory to identify fault segments that haven't moved in a long time, marking them as the most likely locations for future massive ruptures. Immediate Hazards: Shaking and Inundation [S13E1] A Seismic Shift
A major earthquake in this region would trigger a two-phase disaster involving both the land and the ocean. Immediately following a major underwater quake, the water
