Arjuno-Welirang (Indonesia)

Status Normal Eruption 1952 3339m
Stratovolcano (Subduction zone / Continental crust (> 25 km))

The twin volcanoes of Arjuno and Welirang anchor the SE and NW ends, respectively, of a 6-km-long line of volcanic cones and craters. The Arjuno-Welirang complex overlies two older volcanoes, Gunung Ringgit to the east and Gunung Linting to the south. The summit areas of both volcanoes are unvegetated. Additional pyroclastic cones are located on the north flank of Gunung Welirang and along an E-W line cutting across the southern side of Gunung Arjuno that extends to the lower SE flank. Fumarolic areas with sulfur deposition occur at several locations on Gunung Welirang.

The twin volcanoes of Arjuno (right-center) and Welirang (left), seen here rising NE of cultivated land at their feet, anchor the SE and NW ends, respectively, of a 6-km-long line of volcanic cones and craters across a broad valley across from Tengger caldera. A line of pyroclastic cones cuts across the southern flank of Gunung Arjuno and extends to its eastern flank. Fumarolic areas with sulfur deposition occur at several locations on Gunung Welirang.
