 The Eruption of the Supervolcano

Lake Toba is an immense volcanic lake covering an area of 1,707 km2 (1,000 km2 bigger than Singapore) with the island SAMOSIR in the center. Formed by a gigantic volcanic eruption some 70,000 years ago, it is probably the largest resurgent caldera on Earth. Some studies say it might have been associated with causing previous ice age/climate change and the largest human population bottleneck ever. 
 
The eruption of the Toba volcano gave us one of the greatest disasters of humanity which we are aware. Only a few people survived and thus ensured the survival of mankind on Earth.
From this eruption a huge crater was created, which today is one of the most interesting and beautiful lakes underes planet: the Lake Toba surrounded by a stunning szenery.
Danau Toba or Toba Lake is one of the most popular destinations in Indonesia, especially in Medan, North Sumatra. Danau Toba is the largest volcanic lake in Indonesia, even in the Southeast Asia. Which make it more special is taken from the Samosir Island, an Island that settled in the middle of the lake.
Lake Toba is an area of 1,707 km², we can say that this is 1,000 km² bigger than Singapore. It formed by a gigantic volcanic eruption some 70,000 years ago, it is probably the largest resurgent caldera on Earth. Pulau Samosir or Samosir Island, The island in the middle, was joined to the caldera wall by a narrow isthmus, which was cut through to enable boats to pass; a road bridge crosses the cutting. Samosir island is the cultural centre of the Batak tribe, the indigenous from North Sumatra.
By the eruption of a super volcano (Mount Toba) was estimated to have caused mass death and extinction of several species of living creatures. The eruption of Mount Toba has led to changes in the earth’s weather and the start into the ice age that affects the world civilization.
Lake Toba is actually more like a sea than a lake considering its size. Therefore, the Lake placed as the largest lake in Southeast Asia and the second largest in the world after Lake Victoria in Africa. Lake Toba is also includes the deepest lake in the world, which is approximately 450 meters.
The Lake Toba is about 100 kilometres long, 30 kilometres wide, and up to 505 metres (1,666 ft) deep. Located in the middle of the northern part of the Indonesian island of Sumatra, with a surface elevation of about 900 metres (2,953 ft). It is the largest lake in Indonesia and also the largest volcanic lake in the world.
Lake Toba is the site of a massive supervolcanic eruption estimated at VEI 8 that occurred 69,000 to 77,000 years ago, representing a climate-changing event. It is the largest known explosive eruption on Earth in the last 25 million years. According to the Toba catastrophe theory, it had global consequences for human populations: it killed most humans living at that time and is believed to have created a population bottleneck in central east Africa and India, which affects the genetic make up of the human world-wide population to the present.
It has been accepted that the eruption of Toba led to a volcanic winter with a worldwide decrease in temperature between 3 to 5 °C (5.4 to 9.0 °F), and up to 15 °C (27 °F) in higher latitudes. Additional studies in Lake Malawi in East Africa show significant amounts of ash being deposited from the Toba eruptions, even at that great distance, but little indication of a significant climatic effect in East Africa.
