Stratovolcano
Geureudong (also known as Bur Ni Telong or Bur ni Geureudong) is a remote stratovolcano in northern Aceh, ~17 km northwest of Takengon. The volcano features multiple craters, with the largest ~500 m diameter. Solfataras are present at the summit, with fumaroles and hot springs at the base.
Warning: Geureudong is dormant with persistent solfataric activity. Hazards include toxic gas emissions and potential phreatic explosions. The region is seismically active due to the Great Sumatran Fault.
Geology and Volcanology
Geureudong is an andesitic stratovolcano with multiple craters and extensive hydrothermal manifestations (solfataras, fumaroles, hot springs). Older nearby centres include Geureundong, Salah Nama, and Pepanji. Due to its remoteness, monitoring relies on regional seismic networks and satellite data from the Indonesian Centre for Volcanology and Geological Hazard Mitigation (PVMBG).
Current Activity (January 2026)
Geureudong continues low-level solfataric activity at the summit with fumaroles and hot springs at the base. No eruptive or significant changes have been reported. Satellite observations show no thermal anomalies indicative of unrest. The volcano remains dormant.
Eruption History
Confirmed eruptions in the 19th and early 20th centuries: 1937, 1924, 1919, 1856, 1839, 1837. No activity since 1937.
