An aerial view from the SW on 12 September 1991 shows an eruption plume from Raung volcano in eastern Java dispersed to the NW by strong winds. Behind Raung is Ijen caldera, capped by the post-caldera cone of Gunung Merapi (upper right). The light spot below and to the left of Merapi is Kawah Ijen, a renowned crater lake. The flat-topped volcano at the upper left is Gunung Baluran, which occupies the NE-most tip of the island of Java.
