Description: From McGimsey and Neal, 1996: "Observers in the village of Atka, located 15 km (9 mi) to the south, reported a very strong sulfur smell on Monday, May 1 [1995], and a substantial, but lesser, sulfur smell on Thursday, May 4 coincident with the sighting of a small plume-like cloud over Kliuchef volcano. Inclement weather on May 1 prevented direct observation of the volcano. The plumes did not appear on satellite images AVO analyzed that week. The smell of sulfur has been reported previously in Atka village, however, the odors in May were regarded as particularly strong. Satellite images on May 3 showed a hot spot on Korovin, possibly corresponding to one of the fumarolic fields.

From Smithsonian Institution (1995): "Observers in the village of Atka on Atka Island in the central Aleutians reported a very strong sulfur smell on 1 May, and to a lesser extent on 4 May when they observed a small plume-like cloud over Kliuchef. Fumarolic areas exist on or near both Korovin and Kliuchef volcanoes, N of the village. Korovin was active most recently in 1987, and Kliuchef has had Holocene activity. Satellite images did not reveal any plume-like clouds associated with the island, however, a "hot-spot" possibly of fumarolic areas, was observed. A similar sulfur smell was reported by residents in December 1993, at about the same time they felt rumbling from a M 5.1 earthquake (Global Volcanism Network Bulletin v. 18, no. 11)."
