Tandikat-Singgalang Volcano — Indonesia

This volcanic complex is dominated by the Singgalang stratovolcano and the smaller Tandikat edifice ~4.5 km SSW. They are located ~15 km WSW across the Bukittinggi plain from Marapi volcano. No eruptions are known from Singgalang, which hosts a lake in the summit crater. The summit of Tandikat has a partially eroded 1.2-km-wide crater containing a large central cone capped by a 360-m-wide crater containing a small lake. The only known eruptions are from Tandikat; three events reported in the late 19th and early 20th centuries produced minor explosive activity.
