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.
4 Οκτ 2024 · The Barry Arm landslide is a large (~500 M m 3 or 650 M yd 3) landslide located in the northwestern corner of Prince William Sound, Alaska. Rapid failure of the landslide has the potential to create a tsunami that results in life-threatening waves and currents in Barry Arm, Harriman Fjord, Port Wells and adjacent fjords.
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.
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.
A large steep slope in the Barry Arm fjord 30 miles (50 kilometers) northeast of Whittier, Alaska has the potential to fall into the water and generate a tsunami that could have devastating local effects on those who live, work, and recreate in and around Whittier and in northern Prince William Sound.
