Korovin 1996/6
Start: June 29, 1996 [1]
Event Type: Not an eruption
Max VEI: 2 [2]
- Fumarolic or hydrothermal activity [3]
- Meterologic clouds - no eruption [1]
Description: From Neal and McGimsey (1997): "Following a pilot report of volcanic ash at 37,000 feet east of Adak, NOAA/SAB detected a plume-like cloud on an AVHRR image of the Atka Island area on June 29, 1996. Subsequent analysis and lack of any confirming observations of eruptions by pilots led AVO to the conclusion that the cloud was meterologic in nature. The cloud had suggested possible activity at Korovin, the most historically active stratocone on Atka Island in the central Aleutians (Marsh, 1991).
From Smithsonian Institution (1996): "On 29 June, Japan Airlines reported volcanic ash erupting from Atka. In addition, GEOS-9 satellite images showed a possible small ash cloud in the immediate vicinity of Atka. In early May 1995 residents of Atka village observed a small plume-like cloud over Kliuchef and reported a strong sulfur smell (Bulletin v. 20, no. 5)."
Although AVO discredits this eruption account, the Smithsonian Global Volcanism Program assigns it a VEI of 2, and attributes it to Kliuchef.
