Lake Toba, the largest lake in SE Asia, fills more than half of the 35 x 100 km Toba caldera, the Earth's largest Quaternary caldera. The caldera walls rise steeply 400-1,200 m above the 1,700 km2 lake, which is one of the world's deepest with a maximum depth of 530 m. This view looks south from the northern caldera rim.
