Lake Toba Event - 73000 Years BC

(Ekspedisi Cincin Api Kompas)
Jakarta (DreamLandLibrary) - 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 Samosir Island.

Lake Toba has long been an important tourist destination in North Sumatra besides Bukit Lawang, Berastagi and Nias, attracting domestic and foreign tourists. For more complete information about Lake Toba please see here

History
It is estimated that Lake Toba occurred during the explosion around 73,000-75,000 years ago and is the most recent eruption of the supervolcano (super volcano). Bill Rose and Craig Chesner of Michigan Technological University estimate that volcanic material spewed out of the mountain is 2,800 km³, with 800 km³ ignite rock and 2,000 km³ volcanic ash expected to be blown to the west for 2 weeks. Volcanic dust in the wind has spread to half the earth, from China to South Africa. The eruption occurred for 1 week and throw the dust up to 10 km above sea level.

This incident caused mass death and in some species also followed by extinction. According to some DNA evidence, this eruption also reduced the number of people to around 60% of the total population of the earth at that time, which is about 60 million people. The eruption also contributed to the ice age, although experts are still debating it.

After the eruption, a caldera was formed which was then filled with water and became what is now known as Lake Toba. Upward pressure by magma that has not yet come out causes the appearance of Samosir Island.

An international multidisciplinary research team, led by Dr. Michael Petraglia, revealed in a press conference in Oxford, United States that new archeological sites have been found quite spectacular by geologists in southern and northern India. The site revealed how people survived, before and after the eruption of the volcano (supervolcano) Toba 74,000 years ago, and evidence of life under the ash heap of Mount Toba. Even though the source of the eruption was 3,000 miles away from the ashes.

For seven years, experts from Oxford University have been researching ecosystem projects in India, to look for evidence of life and living equipment they left behind in a barren field. This area of ​​thousands of hectares turned out to be just savanna (grassland). While animal bones scattered. The team concluded, this vast area was covered with dust from ancient volcanic eruptions.

The spread of volcanic dust is very broad, found almost all over the world. Derived from an ancient supervolcano eruption, namely Mount Toba. Allegations lead to Mount Toba, because found evidence of the same form of volcanic dust molecules at 2100 points. Since the caldera crater which has now become Lake Toba in Indonesia, up to 3000 miles, from the source of the eruption. Even surprisingly enough, it turns out that the spread of dust until recorded up to the North Pole. This reminds experts, how powerful the Toba volcanic eruption was at that time.
