Overview
Slamet is one of Java's most active volcanoes. It has a cluster of about three dozen cinder cones on its lower SE-NE flanks and a single cinder cone on the W flank. It is composed of two overlapping edifices, an older basaltic andesite to andesitic volcano on the west and a younger basaltic to basaltic andesite one on the east.
Gunung Malang II cinder cone on the upper E flank on the younger edifice fed a lava flow that extends 6 km E. Four craters occur at the summit of Gunung Slamet, with activity migrating to the SW over time. Eruptions recorded since the 18th century have originated from a 150-m-deep, 450-m-wide, steep-walled crater at the western part of the summit and have consisted of explosive eruptions generally lasting a few days to a few weeks.

About the Photo
The summit crater of Slamet, Java's second highest volcano at over 3.4 km elevation. Historical eruptions at Slamet have been recorded since the 18th century and have originated from a 150-m-deep, 450-m-wide, steep-walled crater (at the time of this photo). The eruptions have generally been explosive, lasting a few days to a few weeks.
