The Quaternary Singkut caldera is about 9 km in diameter, with the SW half of the rim topographically distinct. Post-caldera cones are located near the south rim, including Sibayak, Pintau, and Pratektekan. Sibayak and Pintau are twin volcanoes within a small compound caldera open to the north.The 900-m-wide Sibayak crater is partially filled on the north by Pintau. A lava flow traveled through a gap in the western crater wall from the summit lava dome of Sibayak; the active geothermal field SE of the summit has abundant solfataras and fumaroles. Area residents record legends of eruptions. Neumann van Padang (1983) cited a report by Hoekstra of ash clouds that were emitted from the volcano in 1881. The town of Berastagi is situated within the larger Singkut caldera immediately SE of the younger cones.
