Lake Toba - Caldera of A Supervolcano
Lake Toba (Indonesian: Lake Toba) is a large natural lake in Indonesia that inhabits the volcanic caldera. The lake has a length of about 100 kilometers (62 miles), a width of 30 kilometers (19 miles) and a depth of up to 505 meters (1,657 feet). Located in the center of the northern part of the island of Sumatra, Indonesia, with a surface height of about 900 meters (2,953 ft), this lake extends from 2.88 ° N 98.52 ° E to 2.35 ° N 99.1 ° E. It is the largest lake in Indonesia and the largest volcanic lake in the world.
Lake Toba is the site of a large supervolcano eruption that is estimated to occur on VEI 8, which occurred 69,000 to 77,000 years ago, and represents climate change events. Recent advances in dating methods show a more accurate identification of 74,000 years ago as a date. This is the largest known explosive eruption on Earth in the last 25 million years. According to the Toba disaster theory, it has global consequences for the human population; It killed most of the humans who were living at that time and is believed to have created population barriers in the Middle East, Africa and India, which affect the genetic make-up of human populations around the world today.
