Seguam 1892/4
Start: April 15, 1892 ± 45 Days [1]
Event Type: Explosive
Max VEI: 3 [2]
Description: Jaggar (1927, citation 1868) reports "a terrific eruption in the spring of 1892, making detonations heard at the native village on Atka, 75 miles away, and exhibiting two jets of cauliflower clouds."
Jaggar (1927, citation 2639) reports Seguam in 1892 "violently active, so that its eruption was seen from Nazan Bay [Atka] and the sky was darkened by the ash."
Presumably these reports refer to the same eruption from Seguam sometime during 1892, although 2 separate eruptions could have occurred.
