Lake Toba is a volcanic lake formerly a length of 100 km and a width of 30 km. Lake Toba is located in the province of North Sumatra. Lake Toba is the largest lake in Indonesia and even South East Asia. Right in the middle of Lake Toba there is a volcanic island known as the island of Samosir.Lake Toba has long been a favorite tourist destination in Berastagi North Sumatra, Bukit Lawang and Nias. The beauty of Lake Toba attract domestic and foreign tourists.
You can see beauty even through satellite imagery applications such as Google Maps.Origin of Lake TobaLake Toba is thought to form when the explosion around 73000-75000 years ago that an eruption Supervolcano (super volcano) the most. 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. Eruptions that occurred during 1 week threw dust up to 10 km above sea level.
This phenomenon cause mass deaths. And in some species also causing extinction. According to some DNA evidence, Toba 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 it is and known as Lake Toba. Magma upward pressure, causing the emergence of Samosir Island.Multidisciplinary team of international researchers, 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. At the site revealed how people survive, before and after volcanic eruptions (Supervolcano) Toba 74,000 years ago, and evidence of life under 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 it was only savanna (grasslands). While animal bones scattered. Tim concludes, quite large area is apparently covered with dust from ancient volcanic eruptions.The spread of volcanic dust was very spacious, found almost all over the world. Derived from an ancient eruption Supervolcano, namely Mount Toba.
Allegations leading to Mount Toba, because it found evidence of volcanic ash forms of the same molecule 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, apparently spread of dust to be recorded to the North Pole. This is reminiscent of the experts, how powerful the super volcano Toba eruption at that time.
However, Lake Toba become its own tourist attraction on the island of Sumatra particularly in North Sumatra. Attracted to Lake Toba?
