Lake Toba is a volcanic lake with a length of 100 kilometers and 30 kilometers wide, located in North Sumatra Province, Indonesia. In the middle of this lake there is a volcanic island called Pulau Samosir.
Lake Toba has long become an important tourist destination in North Sumatra in addition to Bukit Lawang and Nias, attract domestic and foreign tourists.
It is estimated that Lake Toba explosion occurred at about 73000-75000 years ago and an eruption Supervolcano (super volcano), the largest in the history of planet earth for 25 million years.
Even the Toba eruption is considered as a cause of major extinctions that occurred and shrinking population living creatures that exist on earth. According to the opinion of Stanley H. Ambrose of the University of Illinois at Urbana-Champaign in 1998 said that the Toba eruption leaving only some tens of thousands of people remaining on earth.
Another illustration depicting how powerful the Toba eruption is to imagine that volcanic dust was blown from a buildup of dust explosion in India as high as 6 meters.
Bill Rose and Craig Chesner from Michigan Technological University estimate that volcanic materials spewed out of the mountain as much as 2800 km ³, with 800 km ³ of rock Ignimbrite and 2,000 km ³ of volcanic ash which is expected in the wind to the west for 2 weeks. Volcanic dust in the wind has spread to half the earth, from China to South Africa. Explosion occurred during 1 week and throw the dust up to 10 km above sea level.
This incident caused mass death and the extinction of some species also followed. The eruption was also contributed to the occurrence of ice ages, although some experts who argue there.
After the eruption, the caldera formed which is then filled with water and became what is now known as Lake Toba. Pressure upward by magma that has not come out cause the emergence of Samosir Island.
