Beautiful Lake Toba Sumatra

Trip Advisor

Lake Toba is a volcanic lake with a length of 100 kilometers and 30 kilometers wide, located in North Sumatra Province, Indonesia. This lake is the largest lake in Indonesia and Southeast Asia. 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 most recent. 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. 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 was also contributed to the occurrence of ice ages, although the experts still debate.

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 that has found a new archaeological site 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 at 74,000 years ago, and evidence of life under the ash heap of Mount Toba. Though the source of explosion is 3,000 miles, from the distribution of ashes.

For seven years, experts from Oxford University is researching ecosystem project in India, to seek evidence of life and the lives they left behind equipment in a barren desert. Region with an area of thousands of hectares of this was just savanna (grasslands). Meanwhile, animal bones scattered. The team concluded, this vast area was covered with enough dust from ancient volcanic eruptions.

The spread of volcanic dust was extremely 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 in the same 2100 period. Since the caldera crater, now a lake Toba in Indonesia, 3,000 miles, from the source of the eruption. Even that is quite surprising, it turns out that 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 the time. The evidence is found, strengthening the suspicion, that the strength of the eruption and sea waves could wipe out life on Atlantis.
