Summary

These datasets supports the conclusions in the journal article entitled "Variations in community evacuation potential related to average return periods in probabilistic tsunami hazard analysis" as described in the abstract below: Tsunami risk management requires strategies that can address multiple sources with different recurrence intervals, wave-arrival times, and inundation extents. Probabilistic tsunami hazard analysis (PTHA) provides a structured way to integrate multiple sources, including the uncertainties due to the natural variability and limited knowledge of sources. PTHA-based products relate to specific average return periods (ARP) and while there has been considerable attention paid to ARP choice for building codes, guidance [...]

Purpose

The coastal communities of California are threatened by distant tsunamis from earthquake sources from around the Pacific Ocean basin. Comparing evacuation times with tsunami wave arrival times by parcel and land-use within probabilistic tsunami zones can help emergency managers and community planners decide which ARP to use in land-use or evacuation planning. Using acceptable flow depth thresholds according to building codes and engineering guidelines can help emergency managers and community planners find areas where evacuees could go to higher floors when the time to evacuate or the distance to travel is unreasonable.
