Tsunami Inundation Mapping. Coastal Alaska lives 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 Alaska coastlines, the West Coast of the contiguous United States and across the Pacific.
Actual conditions during a tsunami may vary; areas inundated will depend on earthquake-triggered landslides, on-land constructions, tide level, local ground subsidence, and may differ from areas shown on map.
Your official U.S. government weather forecasts, warnings, meteorological products for forecasting the weather, tsunami hazards, and information about seismology.
The Alaska Earthquake Center, in partnership with the Alaska Division of Geological and Geophysical Surveys and the Alaska Division of Homeland Security and Emergency Management, evaluates and maps potential tsunami inundation of coastal communities using numerical modeling of tsunami wave dynamics.
These have produced some of the largest tsunami waves recorded and, unlike earthquake-induced tsunamis, they can strike with no warning. The tsunami travel time maps for various historical events can be accessed here.
16 Αυγ 2023 · Alaska researchers say most of Anchorage is safe from the threat of a tsunami, but they warn that such a wave could affect Girdwood, Hope and some other coastal areas, including the Port of...
22 Αυγ 2024 · Many active faults in Alaska are capable of generating large tsunamis that threaten coastal communities in Alaska and beyond. For example, seafloor deformation during historic Alaska-Aleutian subduction zone earthquakes has generated tsunamis that traveled across the Pacific Ocean and impacted densely populated coasts around the Pacific Rim ...
