Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Kupreanof
Steam plumes (center) rise from a prominent fumarole on the upper SSW flanks of Kupreanof volcano. The 1895-m-high stratovolcano is the largest and NE-most of a group of five relatively closely spaced Quaternary volcanic centers opposite Stepovak Bay. The only known historical activity from Kupreanof consisted of minor steam and ash emission that was reported from the SSW-flank solfatara field in 1987.
