Sinabung sits in a largely agricultural landscape on Sumatra’s northern island, and its eruptions have affected nearby villages, air quality and local transport during active phases.
- Activity and height: The summit elevation is about 2,460 metres, and the volcano has produced frequent eruptions in the 21st century, making nearby areas subject to evacuations and ashfall advisories.
