The SAFRR (Science Application for Risk Reduction) tsunami scenario: executive summary and introduction

California Geological Survey special report 229:

This document presents a tsunami scenario that depicts a hypothetical but plausible tsunami created by an earthquake offshore from the Alaska Peninsula and its impacts on the California coast. The scenario was developed to better understand tsunami impacts to California coastal communities. It includes evaluations of tsunami science such as tsunami source mechanics and tsunami deposits, as well as estimates of potential damage and the socio-economic and environmental impacts from such a scenario.

The document presents evidence for past tsunamis, the scientific basis for the source, likely inundation areas, current velocities in key ports and harbors, physical damage and repair costs, economic consequences, environmental and ecological impacts, social vulnerability, emergency management and evacuation challenges, and policy implications for California associated with this hypothetical tsunami. It also discusses ongoing mitigation efforts by the State of California and new communication products. The intended users are those who need to make mitigation decisions before future tsunamis, and those who will need to make rapid decisions during tsunami events. The results of the tsunami scenario will help managers understand the context and consequences of their decisions and how they may improve preparedness and response.
