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.
Mount Sundoro or Mount Sindoro is an active stratovolcano in Central Java, Indonesia. Parasitic craters and cones are found in the northwest-southern flanks; the largest is called Kembang. A small lava dome occupies the volcano's summit. Historical eruptions mostly mild-to-moderate phreatic eruptions had occurred.
