Why Have the Pyramids Survived Earthquakes? The Science Explained

The pyramids of Giza have stood for centuries despite harsh weather and powerful earthquakes, and a recent study has uncovered the reason why. Researchers measured how the pyramid naturally vibrates and found that its vibration frequency is very different from that of the surrounding ground. This difference is important because when an earthquake strikes, structures are most vulnerable when they vibrate at the same rate as the shaking ground. Since the pyramid and the soil move at different frequencies, less earthquake energy is transferred into the structure, reducing the risk of serious damage. The pyramid's design also helps protect it. Its massive base, low center of gravity, symmetrical shape, and tapering sides all contribute to its stability. Interior chambers and passageways may also help distribute pressure during seismic activity. Researchers believe these features were not intentionally designed to resist earthquakes, but they created an exceptionally resilient structure.
