Natural attractionsof Lake Toba inNorth Sumatra province Simalungun District, the travel time from the city of fieldabout 4 hours by road. Lake Toba is a volcanic lake which is actually the largest volcanic crater in the world, with an island in the middle of the island called Samosir.
Lake Toba has an area of 1707 square miles or more than twicethe size of Singapore, is formed from theeruption of an ancient volcano, according to several studies when the climate is changing the world and bringing the world into an ice age. Giant eruption nearly destroyed the people of this world. Relics can still be seen the eruption of the caldera in the world today is filled with water to Lake Toba. Samosir is thecaldera of the island that is not submerged in water, is located in the middle of Lake TobaBatak and cultural center. Lake Toba is one of thepopular tourist destination in Indonesia, this place is not too crowded and far from the hustle and bustle of thecity, making it suitable for those who want to relax.

HISTORY
Estimated that Lake Toba explosion occurred at about 73000-75000 years ago and an eruption Supervolcano (super volcano) the most recent. Bill Rose and Craig Chesner from Michigan Technological University estimate that volcanic materials spewed out the mountain as much as 2800 km ³, with 800 km ³ of rock overlies 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 in some species also followed extinction. According to some DNA evidence, this eruption also reduced the number of people to about 60% of the total human population of the earth at that time, which is about 60 million people. The eruption also caused the ice age, although experts are still debating.
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.

International multidisciplinary research team, led by Dr. Michael Petraglia, revealed in a press conference in Oxford, the United States has found a new archaeological site that is quite spectacular by geologists in southern and northern India. On the site it was revealed how people survive, before and after volcanic eruptions (Supervolcano) Toba 74,000 years ago, and evidence of life below the ash heap of Mount Toba. Though the eruption source within 3,000 miles, from the distribution of ashes.
For seven years, experts from oxford University is researching ecosystem project in India, to search for evidence of life and equipment life they left behind in a barren desert. Area with thousands of hectares of this was only the savanna (grasslands). While animal bones scattered. The team concluded that large areas is apparently covered with dust from ancient volcanic eruptions. The spread of volcanic dust was very spacious, found almost worldwide. Derived from an ancient eruption Supervolcano, namely Mount Toba. Allegations leading to Mount Toba, because it found evidence of volcanic dust molecules form the same point in 2100. Since the caldera crater, now a lake Toba in Indonesia, 3,000 miles, from the source of the eruption. Even that is quite surprising, was the spread of dust to be recorded up to the North Pole. This is reminiscent of the experts, how powerful the super volcano Toba eruption at that time.
