Anchorage's threat of a tsunami is "extremely low" (According to the Tsunami Warning Center)
According to studies by the National Oceanic and Atmospheric Administration (NOAA) and the United States Geological Survey (USGS), the natural geographical boundaries of Cook Inlet protect Anchorage from a major tsunami. While the 1964 Good Friday Earthquake was the largest earthquake on record for the nation, it did not generate a tsunami in the Cook Inlet.
Annual Statewide Testing of the Tsunami Warning System:
A test of the tsunami warning system is issued annually statewide by the Emergency Alert System. This warning will help keep Anchorage citizens aware of other areas of the state that may be at risk of a tsunami.
