Okmok 1805
Start: 1805 [1]
Event Type: Not an eruption
Description: Hantke (1951) wrote that there was "an eruption on Umnak" in 1805. It is difficult to say if this eruption occurred and was from Okmok. Grewingk (1850, translated 2003 by Fritz Jaensch) who compiled accounts of many travelers to the region during the time period 1760-1850, makes no mention of this eruption. Langsdorff (1812), who was present in the area from 1803 through 1807, also writes "The active volcano on Umnak * * * has been totally still for a fairly long time" - apparently discrediting the later report from Hantke.
