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.

Sorikmarapi is a highly vegetated stratovolcano on Sumatra island, Indonesia. It has a 600 m wide of crater lake at the summit and some sulfur deposits. A small parasitic crater, called Danau Merah, is found at the upper southeast flank of the mountain and several solfatara fields at the eastern flank. During the 19th and 20th century, small phreatic eruptions occurred.

Rajabasa is an isolated 1281-m-high conical volcano along the Sunda Strait at the most southeastern point of Sumatra. It has a well-preserved 500 x 700 m summit crater with a swampy floor. The volcano is covered with vegetation. Although fumarolic activity occurs on the foot and flanks of the volcano and increased activity was reported in April 1863 and May 1892, it is not known when it last erupted.

Hulubelu is an elliptical, 4-km-long caldera the floor of which is about 700 m above sea level and is surrounded by steep walls in South-Eastern Sumatra. Post-caldera volcanism formed central cones and basaltic and andesitic flank volcanoes. Solfataric areas, mud volcanoes, and hot springs occur at several locations, but it is not known for sure when the volcano last erupted, possibly in the Holocene epoch. Thermal areas are aligned North East of and parallel to the Great Sumatran fault, which runs the entire length of the island of Sumatra.

Lubukraya is an andesitic stratovolcano on Sumatra island, Indonesia. It has a broad crater breached to the south and a lava dome at the southern foot of the volcano.

Sarik-Gajah are two pyroclastic cones right at the equator line on Sumatra island, Indonesia. The first cone is Sarik, an andesitic/basaltic vegetated cone. The other is andesic-dacitic Gajah cone, 10 km south-west of the first one and it contains lava flow. No was eruptive history ever recorded from this volcanic complex.
