Jakarta, CNBC Indonesia – A study found that Lake Toba was the origin of human civilization and the spread of life on the African continent.
Toba's eruption in the past was said to be very powerful compared to Mount Tambora. The incident ejected 2,000 cubic kilometers of material.
This natural event caused cooling in several years. Reportedly reaching 5 degrees Celsius.
Based on circulating theories, the volcanic eruption reduced the population to less than 10 thousand people. This phenomenon is related to life in Africa comes from Curtis Marean of Arizona State University.
His opinion is based on excavations in Africa, especially Shifa-Metema 1 which is on the banks of a tributary of the Nile.
Marean's team found small volcanic fragments in the former residence at that time. Even deposited layers were found.
“This study confirms the results from Pinnacle Point in South Africa, the Toba eruption may have changed the African environment, but the community adapted and survived environmental changes due to the eruption,” said Marean, quoted from IFL Science, Friday (22/3/2024).
The Toba eruption is also said to have caused an extreme dry season in northeastern Africa. In the end, the people of the area looked for new water sources.
“When they run out of food in and around water sources in the dry season, they are likely to be forced to move to new water sources,” said Professor John Kappelman.
