Not only the people of Indonesia who know Lake Toba is located in North Sumatra Province, even the international community also started many people know even learn about the origin of the existence of Lake Toba.
After several Geologists conducting research, Turned who would have thought that Lake Toba was actually derived from the eruption of Mount Toba. Starting from the first eruption occurred about 800 thousand years ago. This eruption produced the caldera in the south of Lake Toba, covers an area of Prapat and Porsea.
Furthermore, the second eruption which has a smaller force, occurred 500 thousand years ago. This eruption formed a caldera in the north of Lake Toba. Precisely in the area between Silalahi with Haranggaol. The eruption of two, the third eruption was the most devastating eruption. The third eruption 74,000 years ago produced the caldera, and become what it is today Lake Toba Samosir Island in the middle.
The eruption of Mount Toba third one is indeed remarkable enormity even be called Judgement in antiquity. This eruption can not be compared to anything that has been experienced on Earth since the time when humans could walk upright, even Mount Krakatau which caused tens of thousands of casualties in 1883 is just a small burp. Though Mount Krakatau has explosive power equivalent to 150 megatons of TNT. For comparison: the Hiroshima nuclear bomb explosion has only 0,015 megatons of explosive power, and verbally then power the destruction of 10,000 times weaker than Krakatoa.
Once the enormity of the eruption of Mount Toba to nearly wipe out the human race on this earth, a result of eruptions pose a huge wave of tsunamis, and volcanic ash vomit approximately 2,800 cubic kilometers of ash that is released and spread to the rest of our Earth's atmosphere. The result was extraordinary to have an impact on the reduction of the human population to only about 5,000 to 10,000 humans only. Contemporary man actually comes from a few thousand humans that survived the eruption of Mount Toba around 74,000 years ago.
The eruption of Mount Toba is a volcanic eruption of the most devastating ever known on Planet Earth and nearly wiping out generations of mankind, the eruption of the supervolcano in Indonesia's deifying like the apocalypse in ancient times for almost wiping out the entire human race in his time, timing of events only a few human survivors. Awesomeness Toba eruption is very popular and is a great 3 terdahsyat volcano eruption on the planet Earth and the sun also reportedly shut for about 6 years.
As a result of the eruptions was truly extraordinary to cause Lake Toba is the largest lake in Indonesia and even in Southeast Asia and has a beautiful sight. Especially in the middle of Lake Toba there is one island called the island of Samosir Batak origin is located.
Therefore actually is one of Mount Toba volcano in Indonesia that is most responsible for the almost extinction of the human race. Even today this threat could reappear, given the presence of Mount Toba exactly located below the bottom of Lake Toba that any time the estimate could erupt again. Moreover, Mount Toba until today still have a child, even Sinabung erupted some time ago and Mount Sibayak, a subsidiary of Mount Toba.
