This is a questionable event. Description:
|Start:||December 1907 ||Observed|
Eakle (1908) reported "dense clouds of vapor" from the summit of Korovin. Jaggar (1927) reported "fresh volcanic cinder" on the snowfields near Mt. Kluichef during the same year, and a boiling spring. Hot springs and fumaroles are well-known in the vicinity of Korovin and Kliuchef, and this report may be nothing more than the usual fumarolic and hydrothermal activity.
