Davidof Volcano is a potentially active stratovolcano and caldera remnant in the Aleutian Islands of Alaska, USA, 1,237 miles (1,991 km) from Anchorage. Located on the eponymous island, Davidof is part of the Rat Islands sub-chain. It is also part of the "Aleutian Krakatau", a group of four islands formed when a stratovolcano caved in during the late Cenozoic.
