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 Talang is a stratovolcano in West Sumatra, Indonesia. Talang has two crater lakes on its flanks, the largest of which is 1 x 2 km wide and is called Danau Talang. Mount Talang has had eight confirmed eruptions between 1833 and 1968. A minor eruption followed in April 2005, over 25,000 inhabitants of the local area being evacuated due to fears of further volcanic eruptions.
Mount Talang's most recent eruption was likely to have been triggered by a series of earthquakes that rocked Sumatra in the weeks before the eruption, including one on March 28 2005 that killed more than 600 people on outlying islands.
