A small ash plume, viewed here from the east on the slopes of Mahawu volcano, rises on September 15, 1986 above Tompaluan crater in the saddle between Lokon and Empung volcanoes. This was one of many explosions that occurred at Lokon-Empung during an eruption between March 1986 and May 1987. The peak behind the eruption plume is Gunung Tetawiran, part of a volcanic ridge that extends to the NW from Lokon volcano.
