Tandikat-Singgalang (Indonesia)

Status Unknown Eruption 1924 2854m
Stratovolcano(es) (Subduction zone / Continental crust (> 25 km))

Tandikat and its twin volcano to the NNE, Singgalang, lie across the Bukittinggi plain from Marapi volcano. Volcanic activity has migrated to the SSW from the higher Singgalang, and only Tandikat has had historical activity. 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 with a small crater lake. The only three reported historical eruptions, in the late 19th and early 20th centuries, produced only mild explosive activity.

The historically active Gunung Tandikat lies across the Bukittinggi plain from Marapi volcano in central Sumatra. The summit of Tandikat's twin 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. Three small explosive eruptions, the last in 1924, have occurred in historical time.
