Overview

Smaller than its prominent namesake on Java, Sumatra's Sumbing volcano has a complicated summit region containing several crater remnants and a 180-m-long crater lake. Its only reported eruptions, in 1909 and 1921, produced moderate explosions. Hot springs occur at the SW foot of the volcano.

Volcanic Hazards & Risk Assessment

Regional Volcanic Activity
The Sunda-Banda Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.
