Background
Kupreanof is the largest and NE-most of a group of five relatively closely spaced Quaternary volcanic centers opposite Stepovak Bay. A debris flow or block-and-ash flow with possible juvenile fragments descended a late-Pleistocene valley south of the volcano. The 1895-m-high stratovolcano displays vigorous fumarolic activity. Its only known historical activity consisted of minor steam and ash emission that was reported from a SSW-flank solfatara field in 1987.---
