Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Sumaco
Forested Sumaco volcano rises to 3990 m above the jungles of the western Amazon basin and is seen here in an unusually cloud-free view NE of the road from Baeza to Tena. Sumaco is part of a north-south-trending volcanic chain far to the east of the main Andes volcanic axis and has erupted more alkaline rocks distinct from those of the main chain. Reports of historical eruptions are somewhat ambiguous, although the volcano maintains its symmetrical shape despite heavy rainfall and intense erosion. Photo by Ursy Potter, 2005.
