Background
The symmetrical Vsevidof stratovolcano, near the SW end of Umnak Island, is one of the most prominent volcanoes in the Aleutians. Vsevidof contains a 1.2-km-wide, ice-filled summit crater that is breached by glaciers on the east and north sides. An E-W-trending zone of scoria cones that extends from 1220 m down much of the western flank has been the source of historical eruptions. The bulk of the 2149-m-high cone of Vsevidof was constructed during the Holocene. Young andesitic and dacitic lava flows were extruded from vents on the north and south flanks and on the west-flank rift. The largest lava flow traveled down the west flank to the coast, forming Cape Kigushimkada.---

Remark:
Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
