Lake Toba


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 the island.
Lake Toba has long been an important tourist destination in North Sumatra and Nias Bukit Lawang, attract domestic and foreignLake Toba is expected explosion occurred at about 73000-75000 years ago and an eruption (super volcano) the most recent. Bill Rose and Craig Chesner of Michigan Technological University estimate that the volcanic materials spewed out of 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. The explosion occurred during a 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 also caused the ice age, although experts are still debating.
After the eruption, the caldera formed which was then filled with water and became what is now known as Lake Toba. Upward pressure by magma that has not come out cause the appearance of the island.
International multidisciplinary research team, led by Dr. Michael Petraglia, said in a press conference in Oxford, the United States that has found a new archaeological site that is quite spectacular by geologists in the south and north India. At the site revealed how people survive, before and after volcanic eruptions (Supervolcano) in Toba 74,000 years ago, and evidence of life below the ash heap of Mount Toba. Though the source of the eruption within 3,000 miles, from the distribution of ashes.
For seven years, experts from Oxford University is researching ecosystem project in India, to look for evidence of life and the lives they left behind equipment in a barren desert. Area with an area of ​​thousands of hectares of this was just the savanna (grassland). While the animal bones were scattered. The team concluded that a quite large area was covered with dust from this ancient volcanic eruptions.
The spread of volcanic dust was very wide, are found almost all over the world. Supervolcano eruption comes from an ancient, namely Mount Toba. Allegations leading to Mount Toba, because it found evidence of molecular forms of volcanic ash in the same 2100 period. Since the caldera crater, now a lake Toba in Indonesia, up to 3000 miles, from the source of the eruption. In fact, surprisingly enough, it turns out that the spread of dust caught up to the North Pole. This is reminiscent of the experts, howenormity of the Toba super volcano eruption at the time.


Public confidence about say, there is a legend about the emergence of Toba lake itself. Here's the story. Once Upon a Time there was a fisherman named TOBA. One day, he was fishing in the river. Fish, fish type Mas. He took the fish home. Not taunya, fish, talk to the TOBA. He was very surprised. The fish asked her not to eat TOBA. Changed the fish into a beautiful woman. Toba fell in love with her. They were married. But toba must be eligible when they have children later, TOBA can not say that their child is a child fish. Toba meet her. They had a son named Naidoo. Toba switch jobs to "pangula" or farmer. Naidoo grew into a mischievous child. One day, Naidoo told to eat his mother drove to his father who was working in the fields. But the middle of the road, dropping Naidoo. Samosir picked it up and put back into place. He gave to his father. Toba is very angry. he said "do botul Na ho ni dengke children. Dang suman pangalahom songon jolma. Lao cyan on dengke ho". It means "You really are a child of the fish. Not fit your character is like a human being. Go Fish out of here. Apparently, from a distance, she heard it. Naidoo then ran to her mother, crying. Toba aware of his actions. Instant, lightning appears and seized. Rain falls and rivers overflowed. Naidoo told her to go to the mountain and climb trees too Cleaner. mother back into the fish Mas. river was turned into a lake named lake Toba. Gununug had been turned into islands in the middle of the lake, given the the name of the island. Until now Lake Toba and Samosir island is famous. names are both used as the name of one of the county district Toba Samosir in North Sumatra Province.
