Coast Guard: Additional Actions Needed to Improve Tsunami Emergency Planning in the Pacific Northwest, Report to Congressional Committees [open pdf - 8MB]
From the Highlights: "As the principal federal agency responsible for maritime search and rescue, Coast Guard deploys personnel across the United States. This includes deployments to 39 coastal units in the Pacific Northwest. The Pacific Northwest is also home to seismic hazards, including the Cascadia Subduction Zone. This is a large fault 50-100 miles offshore known to produce large earthquakes and tsunamis that may necessitate the evacuation of Coast Guard personnel and dependents during a major event. The National Defense Authorization Act for Fiscal Year 2021 provides for GAO [Government Accountability Office] to study Coast Guard efforts to plan for the evacuation of its personnel and dependents during a major Cascadia Subduction Zone event. This report addresses, among other things, the extent to which the Coast Guard developed tsunami evacuation plans and procedures for its personnel and dependents in the Pacific Northwest."
