Great Pyramid of Giza's Earthquake Resilience Studied

A recent study by seismologists from Egypt's National Research Institute of Astronomy and Geophysics has looked into how well the Great Pyramid of Giza can handle earthquakes. They found that its unique design has likely helped it endure for over 4,600 years. This iconic structure has survived around a dozen significant quakes, including the 5.9 magnitude earthquake in Cairo in 1992, although some stones did get shifted. Interestingly, despite losing about 30 feet in height since it was built, the Great Pyramid shows no signs of damage from earthquakes, unlike other pyramids. By measuring vibrations at 37 different spots, researchers discovered that the pyramid's internal vibrations were remarkably uniform, which helps spread out stress effectively. They published their results in Scientific Reports in May, highlighting the ancient Egyptians' impressive knowledge of geotechnics.
