The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred about 74,000 years ago, during the Late Pleistocene, [2] at the site of present-day Lake Toba, in Sumatra, Indonesia.
The lake is about 100 kilometres (62 miles) long, 30 kilometres (19 mi) wide, and up to 505 metres (1,657 ft) deep. It is the largest lake in Indonesia and the largest volcanic lake in the world. [1] Toba Caldera is one of twenty geoparks in Indonesia, [2] and was recognised in July 2020 as one of the UNESCO Global Geoparks. [3] [4] [5]
The 2004 Indian Ocean earthquake is thought to have triggered activity in both Leuser Mountain [45] and Mount Talang, [46] volcanoes in Aceh along the same range of peaks, while the 2005 Nias–Simeulue earthquake sparked activity in Lake Toba, a massive caldera in Sumatra. [47]

A high volcanic cone with a single central vent formed before the 1815 eruption, which follows a stratovolcano shape. [18] The diameter at the base is 60 kilometres (37 mi). [8] The volcano frequently erupted lava, which descended over steep slopes. [18] Tambora has produced trachybasalt and trachyandesite rocks which are rich in potassium.
The largest volcano of Sumatra is the supervolcano Toba within the 100 km (62 mi) × 30 km (19 mi) Lake Toba, which was created after a caldera collapse (est. in 74,000 Before Present). [2] The eruption is estimated to have been at level eight on the VEI scale, the highest level for a volcanic eruption.
