Barry Arm, Alaska Landslide and Tsunami Monitoring
Active
By Landslide Hazards Program
February 22, 2021
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.
The U.S. Geological Survey is supporting the monitoring efforts in the Barry Arm fjord in Alaska. Please see these sites for information:

Subaerial landslides at the head of Barry Arm Fjord in southern Alaska could generate tsunamis (if they rapidly failed into the Fjord) and are therefore a potential threat to people, marine interests, and infrastructure throughout the Prince William Sound region.

Potential Landslide Paths and Implications for Tsunami Hazards in Glacier Bay, Alaska – An Initial Investigation
Glacier Bay and its inlets are a popular destination for cruise ships and passenger boats; about 540,000 people visited Glacier Bay National Park and Preserve (GBNPP) in 2017. A typical tour of the Bay traverses the entire length up to the glacier calving viewpoints in the Johns Hopkins and Tarr Inlets. A 2018 article “Landslides and Giant Waves” by the National Park Service (NPS) states, “The...
