Description :
Historic- and prehistoric-tsunami sand deposits are used to independently establish runup records for tsunami hazard mitigation and modeled runup verification in Crescent City, California, located in the southern Cascadia Subduction Zone. Sand sheet deposition from the 1964 historic tsunami closely corresponds to the landward extent of large debris transport and structural damage in the Crescent City waterfront. The sand sheet deposits therefore provide a proxy for maximum hazard or ‘kill zone’ in the study area and use in the planning of emergency response and rapid evacuation.
