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.
Marapi (also known as Merapi or Berapi) is a volcano in West Sumatra, Indonesia. Its name means Mountain of Fire, and it is the most active volcano in Sumatra. Its elevation is 2,891.3 m (9,485.9 ft). A number of cities and towns are situated around the mountain, including Bukittinggi, Padang Panjang and Batusangkar.
According to legend, the mountain is the origin of the Minangkabau people. Accordingly, there are large numbers of upright burial stones in the region which are oriented in the direction of the mountain.
