Mount Kupreanof is a stratovolcano on the Alaska Peninsula, United States. It is the largest and the northeasternmost in a group of five volcanoes opposite from Stepovak Bay. Mount Kupreanof displays extremely strong fumarole activity and its latest eruption in 1987 produced minor steam and ash emission.[1] This is the only known historical eruption from Mount Kupreanof.
