Vsevidof 1790/5
Start: May 30, 1790 [1]
Event Type: Not an eruption
- "Smoke" [2]
- Discredited account - no eruption [3]
Description: Grewingk (1850, translated 2003 by Fritz Jaensch) writes that Sarychev reported Vsevidof smoking in 1790. Coats (1950) reports smoke on May 30, 1790. The English translation of Sarychev is less clear - for the 30th of May, it reads: "The island Umnak is level on its western side, but elevated towards the north-east. It extends as far as the strait which separates it from Unalaschka, and terminates with mountains; several of which, rising above the others, are volcanic, and crowned with eternal snow. It stretches, from south-west to north-east, 55 miles in length. The strait between Umnak and Unalaschka is at least 2 miles and a half in width. About 30 versts from the strait, and about 7 miles from Umnak, are two rocks, surrounded by water; which, on the 31st of May, lay five miles distant towards the north-west. We were then in latitude 52 degrees 49 minutes; and longitude 192 degrees 45 minutes."
