It is difficult to think that there was a period in which humanity and its proliferation were in grave danger. A study published by the journal Nature confirmed that this was real and happened more than 70,000 years ago.
The study reveals that the Earth went through some dark and asphyxiating days, due to the mega eruption of the volcano of Monte Toba, a explosion that caused a volcanic winter for more than 10 years.
Scientists point out that, due to the impressive wave of eruptions, humanity was really in danger of disappearing. According to the information revealed, this volcanic catastrophe that occurred north of the island of Sumatra about 74,000 years ago, may have reduced the human population to a maximum of 10,000 or even 1,000 couples with reproductive capacity.
The eruption was of gigantic dimensions; the volcano expelled large quantities of lava and ash that spread high levels of pollutants in the atmosphere and which would have diminished sunlight to levels between 25% and 90%, causing death of plants, forest fires and as a result the death of millions of mammals.
Reports indicate that the ash spread to more than 191 cubic miles and the eruption left a crater 62 miles long by 21 miles wide, which today is the largest volcanic lake in the world.
The explosion was so big that the researchers were able to document that the ashes and materials expelled like fragments of glass came to be found thousands of miles away as in India, the Indian Ocean, the Bay of Bengal and the South China Sea.
The archaeologist Panagiotis Karkanas managed to discover a series of artifacts that would confirm this theory. The scientists found articles of work, tools, as well as the pieces of glass that were used by humans of that time, who were sheltered in a series of caves.
The discovery took place during an archaeological excavation in South Africa, about 5,500 miles from the origin of the eruption, where it was found that these shelters represented a whole human settlement, as they took advantage of the living conditions of the place such as the coastal resources.
The study shows in particular that, despite the eruption of Mount Toba, humans thrived along the coast of southern Africa, so it is estimated that there may be more evidence of different groups of people who managed to survive those devastation times.
