Shake, Rattle, and Wave: USGS Releases Tsunami Risk Reduction Study

The U.S. Geological Survey (USGS) has released a report called "The Science Application for Risk Reduction (SAFRR) Tsunami Scenario". This report depicts a potential tsunami created by an earthquake offshore from the Alaska Peninsula and how it might impact the coast of California.

According to the report, "[t]he tsunami scenario is a collaboration between the U.S. Geological Survey (USGS), the California Geological Survey, the California Governor's Office of Emergency Services (Cal OES), the National Oceanic and Atmospheric Administration (NOAA), other Federal, State, County, and local agencies, private companies, and academic and other institutions. This 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."

The report also discusses efforts by the State of California to diminish tsunami disasters. The state has created new communication tools to allow for quick decisions during a tsunami event, as well as other natural disasters.

The report goes on to evaluate how effective the responses were for the tsunami response.
