Jakarta, CNBC Indonesia – A study found that the events that formed Lake Toba were the origins of human civilization. The events in Toba were the trigger for human ancestors to leave Africa and spread across the Earth.
The eruption that formed Lake Toba in the past was said to be very powerful compared to Tambora. This incident ejected 2,000 cubic kilometers of material from the bowels of the Earth.
The events in Toba caused cooling throughout the Earth for many years. It is reported that the Earth's temperature at that time reached 5 degrees Celsius.
Based on circulating theories, the volcanic eruption reduced Earth's population to less than 10 thousand people. The phenomenon is related to life in Africa, according to 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 the environmental changes caused by the eruption,” said Marean, quoted from IFL ScienceFriday (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.
