Sibayak volcano in NE Sumatra and its twin volcano Mt. Pinto are constructed within a compound caldera. The slightly higher Mt. Pinto partially overtops the 900-m-wide crater of Sibayak on the north. The summit contains a lava dome and an area of hydrothermal alteration visible in this photo. An ash eruption from Sibayak was recorded in 1881, and area residents note legends of eruptions.
