If you have visited Machu Picchu, you might have noticed in the construction separation between the rocks of the buildings.
According to an article published by Andina News Agency, the Geological, Mining and Metallurgical Institute (Ingemmet) of Peru revealed that an earthquake of at least 6.5-magnitude, registered around 1450, caused the deformation of the walls of Machu Picchu and motivated the Incas to start using a seismic-resistant architecture.
“This is one of the first results of the Cusco-Pata scientific research project, developed by Ingemmet to identify telluric movements that occurred in the past and how they affected ancient cultures, such as the Inca and the Wari”, the news agency wrote.
According to historical information, Cusco was affected by nigh magnitude earthquakes, two of them took place in 1650 and 1950, but it was never possible to determine which was the geological fault that generated these telluric movements.
“The Ingemmet project focused on two active geological faults that are close to the city of Cusco: Tambomachay and Pachatusan, which, due to their characteristics, are capable of generating large earthquakes, which undoubtedly affect the development of society”, according to information from Andina.
