Geureudong

Telong, Bur ni

Stratovolcano · Indonesia · 2617m

Historically active Bur ni Telong volcano, seen here from the SE, was constructed on the southern flank of Bur ni Geureudong volcano, part of which is visible in the background. The two summits of the complex are 4.5 km apart and are similar in elevation. The summit crater has migrated to the ESE, leaving arcuate crater rims. Lava flows are exposed on the southern flank. Explosive eruptions were recorded during the 19th and 20th centuries.

Geological summary

The conical Bur ni Telong volcano was constructed at the southern base of the massive Bur ni Geureudong volcanic complex, one of the largest in northern Sumatra. The historically active volcano lies 4.5 km from the summit of Geureudong,and its summit crater has migrated to the ESE, leaving arcuate crater rims. Lava flows are exposed on the southern flank. Explosive eruptions were recorded during the 19th and 20th centuries.

From Wikipedia

Geureudong or Bur ni Geureudong or Bur ni Telong is a stratovolcanic complex in northern Sumatra, Indonesia. The official name of the whole complex is confusing between the two adjacent volcanoes: Bur ni Geureudong and Bur ni Telong. Two other volcanic cones are Salah Nama and Pepanji, and there are small sediment hills. Bur ni Geureudong has been eroded since the Pleistocene age, but has solfatara and hot springs on its flanks. Bur ni Telong is located in the south of Bur ni Geureudong. Bur ni Telong has active crater that lava flows are exposed in the southern flank.
