Samosir Island

Lake Toba is a large natural lake occupying the caldera of a super volcano. The lake is about 100 kilometers long, 30 kilometers wide, and up to 505 meters (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 meters. It is the largest lake in Indonesia and also the largest volcanic lake in the world.

Lake Toba is the site of a massive super volcanic 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 worldwide population to the present.

Samosir, or Samosir Island, is a large volcanic island in Lake Toba, located in the north of the island of Sumatra in Indonesia. Administratively, Samosir Island is governed as six of the nine districts within Samosir Regency. The lake and island were formed after the eruption of a supervolcano some 75,000 years ago. The island was originally connected to the surrounding caldera wall by a small isthmus, which was cut through to aid navigation.

At 640 square kilometres (247 sq mi), Samosir is the largest island within an island, and the fifth largest lake island in the world.It also contains two smaller lakes, Lake Sidihoni and Lake Aek Natonang. Across the lake on the east from the island lies Uluan Peninsula. The island is linked to the mainland of Sumatra on its western part by a narrow isthmus connecting the town of Pangururan on Samosir and Tele on mainland Sumatra. Tele consequently offers one of the best views of Lake Toba and Samosir Island.
