The forested summit of Tongkoko volcano at the NE tip of Sulawesi is truncated by a large elongated, 1 x 2 km wide crater that contains a central cone. In 1801 a crater lake was observed. Eruptions have occurred at Tongkoko during historical time from both summit and flank craters. Photo by A.R. Sumailani, 1973 (Volcanological Survey of Indonesia).
