- SECTOR ANCHORAGE, SUBMERGED LAND ACT (SLA) - PRINCE WILLIAM SOUND General / Hazards To Navigation / Hazards Location: 61-10.32N 148-28.50W 61-10.24N 148-03.45W 61-02.28N 148-03.45W 60-55.81N 148-28.99W 61-10.32N 148-28.50W The State of Alaka is issuing routine updates on the Barry Arm Landslide Tsunami risk. This threat is located in Barry Arm and has the potential to create a tsunami if/when a landslide is generated that impacts the water in Barry Arm. If/when this occurs localized wave heights will be very hazardous in Barry Arm and Harriman Fjord. Port Wells and Passage Canal will also see inundation and strong, unusual currents for hours following an event. The geologic makeup of the area is similar to Alaskan locations where two previous landslide caused tsunamis occurred, in Lituya Bay (1958) and Icy Bay (2015), both causing extremely large but localized tsunamis. Mariners should maintain vigilance when in the vicinity of Barry Arm or nearby waters and be prepared to depart the area if any unusual geologic activity is observed. Studies are being conducted and the situation is being monitored to allow for a better understanding of the potential results of a slide.
