Toba Lake Indonesia

Toba Lake is an extraordinary natural wonder of the world located in North Sumatra – Indonesia. This enormous crater lake consists of an island at over 1,145 square km, and a depth of 450 meters. This is the largest lake in Southeast Asia and one of the deepest lakes in the world.

History of Toba Lake

The Toba eruption (the Toba event) occurred at what is now Lake Toba about 73,700±300 years ago. It was the last in a series of at least four caldera-forming eruptions at this location, with the earlier known caldera having formed around 1.2 million years ago. This last eruption had an estimated VEI of 8, making it the largest-known explosive volcanic eruption in the Quaternary.

Bill Rose and Craig Chesner of Michigan Technological University have estimated that the total amount of material released in the eruption was at least 2,800 km³ (670 cu mi) about 2,000 km³ (480 cu mi) of ignimbrite that flowed over the ground, and approximately 800 km³ (190 cu mi) that fell as ash mostly to the west.

However, as more outcrops become available, Toba possibly erupted 3,200 km³ (770 cu mi) of ignimbrite and co-ignimbrite. The pyroclastic flows of the eruption destroyed an area of least 20,000 km² (7,700 sq mi), with ash deposits as thick as 600 m (2,000 ft) by the main vent. The eruption was large enough to have deposited an ash layer approximately 15 cm (6 in) thick over all of South Asia; at one site in central India, the Toba ash layer today is up to 6 m (20 ft) thick and parts of Malaysia were covered with 9 m (30 ft) of ash fall.

Latitude of Lake Toba

The lake is located in the middle of the northern part of the island of Sumatra. Surface elevation is about 900 metres (2,953 ft). The lake stretches from 2.88°N 98.52°E to 2.35°N 99.1°E. It is about 100 kilometres long, 30 kilometres wide, and up to 505 metres deep.

It is the largest lake in Indonesia and the largest volcanic lake in the world. Toba Caldera is one of twenty geoparks in Indonesia, and was recognised in July 2020 as one of the UNESCO Global Geoparks.
