41 views

Machu Picchu has withstood centuries without significant damage from earthquakes due to its unique construction technique. The Incas used a method called 'ashlar masonry,' where stones are cut to fit together without mortar. This technique allows the stones to move slightly and settle back into place during seismic activity, preventing the structure from collapsing. Furthermore, the strategic placement of Machu Picchu between two fault lines may have necessitated such ingenious building methods to ensure its durability.
