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.
Lewotolo is a stratovolcano located in the north-central part of the island of Lembata. The volcano is about 1,450 meters high and last erupted fiercely in 1951, while there also was a smaller eruption in 1980.
