TSUNAMI HAZARD MITIGATION FOR ALASKA
Coastal Alaska communities live with the most serious tsunami risk in the United States. Historically, tsunamis generated by earthquakes in Alaska have caused damage and loss of life along the West Coast and across the Pacific. Here in Alaska, though, tsunamis generated by nearby earthquakes represent “near-field” hazards. This means people may have minutes rather than hours to reach safety.
The Earthquake Center works to make our coastal communities safer by providing state and local officials with the best possible information for addressing the tsunami hazards faced by their communities. We tackle community safety through the following projects:
In partnership with the Alaska Division of Geological and Geophysical Surveys and the Alaska Division of Homeland Security and Emergency Management, we evaluate and map potential inundation using numerical modeling of tsunami wave dynamics. The maps incorporate the best tsunami science available at the time of publication.
MARITIME RESPONSE GUIDANCE DOCUMENTS
These documents provide response guidance in the event of tsunamis for small vessels such as recreational sailing and motor vessels, and commercial fishing vessels.
For communities that have well-defined tsunami scenarios, it is possible to estimate the amount of time required to evacuate to high ground by foot.
