Details for: Gareloi
Gareloi Volcano in the western Aleutian Islands is seen from the south. Levied lava flows from a 1980s eruption drape the south flank of the southern summit crater. The white zone on the crater headwall is an extensive fumarole field. The 8 x 10 km diameter Gareloi Island consists of a stratovolcano with two summits and a SE-trending fissure. This prominent fissure was formed during an eruption in 1929 and extends from the southern summit to the sea. Photo by Game McGimsey, 2003 (Alaska Volcano Observatory, U.S. Geological Survey).
