History The formation of Lake Toba and its islands In Samosir Sumatra

The last eruption of Mount Toba spewed out more than 1000 cubic kilometers of eruption material. The height of the eruption reaches 50 km. The ash material spread throughout the Earth's atmosphere to cover the sunlight that entered the earth for several years. As a result, the earth's temperature at that time fell to 3-5 degrees Celsius.

Besides producing a large tsunami, the eruption of Mount Toba also resulted in the mass death of humans and several other species of living things. From some of the results of research that has been done, the eruption of this mountain is thought to shrink more than 60% of the human population at that time, which is about 60 million people.

This allegation is based on two things. First, the ash material that falls all over the world has hoarded a portion of human habitat. Second, the absence of incoming light causes no photosynthesis of plants. This has an impact on the scarcity of food ingredients resulting in devastating hunger which leads to mass death.

After the eruption, this mountain formed the caldera which then filled with water and eventually became the largest lake in Southeast Asia. This lake is known as Lake Toba.

Although experts still differ in their opinion about this, a multidisciplinary team of international researchers led

The site reveals how people survived, before and after the volcanic eruption (supervolcano) Toba 74,000 years ago, and evidence of life under the ashes of Mount Toba. Despite the source of the eruption in 3,000 miles, from the distribution of ash.

For seven years, experts from the University of Oxford project examined ecosystems in India, looking for evidence of life and the equipment they left behind in barren deserts. This area of ​​thousands of hectares is only savanna (grassland). While animal bones are scattered. The team concluded, a large enough area turned out to be covered in dust from an ancient volcanic eruption.

The story since the present crater caldera is Lake Toba in Indonesia, 3,000 miles, from the source of the eruption. In fact, quite surprisingly, it turns out that the spread of dust will be recorded to the North Pole. This reminds experts, how powerful the super Toba volcanic eruption was at that time.
