Vsevidof 1999/1
Start: January 28, 1999 [1]
Event Type: Not an eruption
- "Smoke" [1]
- Steam [1]
Description: From McGimsey and others (2004): "On January 28, a resident in Nikolski on Umnak Island called at 4 pm AST to report 'black smoke, dark puffing' issuing from the top of nearby Vsevidof Volcano. The weather was cold and clear, and a M6.1 regional earthquake had occurred in the area the previous evening, followed by numerous aftershocks.
"AVO received no additional or subsequent reports of activity. Routine examination of satellite data by AVO remote-sensing specialists earlier in the week revealed that indeed a minor steam plume was present at the volcano. The wintertime low sun-angle likely accounts for the reporter's description of 'black smoke'.
