Atacama is desert The world’s most “difficult to live” is located in Chile, which has long been known as a geological region with an extremely complicated history, many beast once dominated, various groups of ancient people came and went.
According to Science Alert, New international research led by anthropologist Diego Salazar from the University of Chile shows that the Atacama’s coastal strip was once inhabited about 3,800 years ago. However, soon after the trace People suddenly “disappeared” for 1,000 years and then reappeared.
This led scientists to the study of marine sediments. Many traces of humans and animals were revealed in an unexpected way: staying for a long time in a quiet coastal area and then suddenly being thrown inland.
Research just published on Science Advances It also said that the soil structure was also unusually uplifted over the previous 3,800 years.
According to geologist and tsunami expert James Goff from the University of New South Wales (Australia), a member of the research team, that could only be caused by an unimaginable super-tsunami.
The source of the super tsunami was a “monster” earthquake of up to 9.5 magnitude. For comparison, the famous earthquake of April 2015 caused a series of consecutive disasters in many regions of Nepal – India, including Mount Everest and killing at least 8,000 people, with a magnitude of 7.8 or 8. ,1 degree richter.
The area was previously thought to be “vulnerable” to super-earthquakes, due to its proximity to the convergence of the Nazca and South American tectonic plates.
3,800 years ago, the people living here were Stone Age communities, still living mainly by hunter-gatherers. The mega-catastrophe toppled rock structures twice, accompanied by a powerful tsunami that wreaked havoc as it hit and as it flowed back into the ocean and swept everything away.
The destruction was so monstrous that the impact on any few surviving humans had to be so strong that the entire area remained uninhabited for nearly 1,000 years despite the stretch of land already being habitually settled. of ancient humans during the previous 10,000 years.
According to Dr. James Goff, because the root cause is from the impact between the tectonic plates that are still moving, “super monsters” from the ground can still arise again. Currently the area is densely populated and is a popular tourist destination, so the disaster will be catastrophic “unless we learn from this discovery”, he stressed.
