Raung (Indonesia)

Status Normal Eruption 2015 3260m
Stratovolcano (Subduction zone / Continental crust (> 25 km))

Raung, one of Java's most active volcanoes, is a massive stratovolcano in easternmost Java that was constructed SW of the rim of Ijen caldera. The unvegetated summit is truncated by a dramatic steep-walled, 2-km-wide caldera that has been the site of frequent historical eruptions. A prehistoric collapse of Gunung Gadung on the W flank produced a large debris avalanche that traveled 79 km, reaching nearly to the Indian Ocean. Raung contains several centers constructed along a NE-SW line, with Gunung Suket and Gunung Gadung stratovolcanoes being located to the NE and W, respectively.

Raung volcano, near the eastern tip of Java, is truncated by a steep-walled, 2-km-wide caldera. One of Java's most active volcanoes, Raung produces frequent moderate explosive eruptions, like this one in 1988 from a cone within the caldera, that keep the upper flanks of the volcano sparsely vegetated. Raung forms part of a NW-SE-trending chain of volcanoes constructed near the SW rim of the massive Ijen caldera.
