Tsunami deposits: A broader perspective



Tsunami Sedimentology and Its Role in Hazard Awareness, Preparedness, Assessment, and Mitigation; San Francisco, California, 2–3 December 2011 Tsunami sediments are recorders of recent and past tsunamis. While studies of recent tsunamis document erosional and depositional features created during tsunami inundation, the exploration of prehistoric (paleo-) tsunami deposits poses a more complex problem due to uncertainties introduced by incomplete preservation and incomplete knowledge of environmental conditions at the time. A better understanding of sedimentary processes governing deposit generation will improve our ability to employ paleotsunami deposits as tools to reconstruct prehistoric tsunami characteristics.
