About

Mount Edgecumbe (Tlingit: Lʼúx, Russian: Эджком) is located at the southern end of Kruzof Island, Alaska, about 15 miles (24 km) west of Sitka. The dormant volcano is about 9.9 miles (16 km) east of the Queen Charlotte Fault that separates the North American and Pacific Plates, and is the highest point in the Mount Edgecumbe volcanic field, an area of about 100 square miles (260 km2) on Kruzof Island that also includes Crater Ridge and Shell Mountain.

Mount Edgecumbe has not had a major eruption in 4000 years. Recent earthquake activity shows magma intrusion at a depth of 3 miles (5 km), but as of 2022, an eruption does not appear to be imminent. It has been classified by the Alaska Volcano Observatory (AVO) as "historically active". Mount Edgecumbe was a prop in a 1974 April Fools' Joke, which involved tricking the citizens of Sitka into believing the volcano was erupting.
