The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Indo-Australian plate. Some of the volcanoes are notable for their eruptions, for instance, Krakatau for its global effects in 1883, Lake Toba for its supervolcanic eruption estimated to have occurred 74,000 Before Present which was responsible for six years of volcanic winter, and Mount Tambora for the most violent eruption in recorded history in 1815.
Tandikat is a volcano in West Sumatra. Its elevation is 2,438 m (7,999 ft). It is a twin volcano with Mount Singgalang, which is located to the north-north-east of Tandikat. However, only Tandikat has had historical volcanic activity. The city of Padang Panjang is located at the foot of the mountain.
