Peuet Sague

Complex volcano · Indonesia · 2785m

The summit crater of Peuet Sague is part of a large volcanic complex in NW Sumatra. The first recorded historical eruption took place during 1918-21, when explosive activity and pyroclastic flows accompanied summit lava-dome growth. The historically-active crater has typically produced small-to-moderate explosive eruptions.
