The historically active Gunung Tandikat lies across the Bukittinggi Plain from Marapi volcano in central Sumatra. The summit of Tandikat's neighboring volcano, Singgalang, is seen here from Bukittinggi city across the steep-walled Ngarai canyon north of the volcano. Gunung Tandikat contains a central cone and a small crater lake constructed within a larger 1.2-km-wide crater. Small explosive eruptions have occurred recently, including in 1924.
