Herbert Island is a volcanic island in Alaska’s Aleutian chain, in the Islands of Four Mountains subgroup of the Bering Sea. Known in Aleut as Chiĝulax̂ and in Russian as Херберт, it lies near Chuginadak Island and Yunaska Island. The island is roughly circular, and nearly all of it is occupied by Herbert Volcano, which rises to about 4,200 feet. Thought to be a stratovolcano, it has a caldera about 2 kilometers wide that is considered one of the largest in the Aleutian Islands. Although it stands within a highly active North Pacific volcanic arc, no eruptions have been recorded there.
