Kupreanof reported activity



Event Name : Kupreanof 1994/7

Start:July 22, 1994 Observed

Fumarolic or hydrothermal activity: BibCard
Steam: BibCard
Eruption Type:Not an eruption.

Description: From Neal and others (1995): "Kupreanof is a deeply eroded stratovolcano with no known historical eruptions. Holocene debris avalanche deposits have been recognized, however, and there is a vigorous fumarolic area marked by sulfur deposits at an elevation of 1,524 m (5,000 ft). Steaming from Kupreanof has been noted in the literature as 'eruption reports' in the past (Smithsonian Institution, 1987).

"* * * On July 22, a pilot reported a steam plume over Kupreanof reaching an altitude of 2,400 m (8,000 ft). Although steaming from Kupreanof has been noted for at least the last 50 years, the robustness of the plume was considered unusual by this veteran pilot. No SIGMETS were issued by NWS, however, as no ash was detected. AVO took no further action."
