Could Any Earthquake Topple the Great Pyramid
The article discusses Khufu's Pyramid's ability to withstand earthquakes, especially in light of a recent 5.5 magnitude earthquake that struck eastern Egypt. Scientific studies confirm that the intensity of the earthquake alone does not determine the likelihood of the pyramid collapsing; rather, it depends on several factors, such as the proximity of the epicenter, its depth, the duration of the tremor, and whether the wave frequencies match the pyramid's natural frequencies. It has been proven that strong earthquakes that are distant are less dangerous to the pyramid than weaker ones that are nearby and direct, as they may induce resonance that weakens the structure. Although some ancient structures have been damaged by historical earthquakes, Khufu's Pyramid has remained resilient because it was built to withstand numerous vibrations, with a natural frequency between 2 and 2.6 Hz. Experts reaffirm that the real danger depends on short, shallow, and intense earthquakes occurring close by, which could disrupt the equilibrium that has maintained the pyramid’s stability for thousands of years—not solely on the earthquake's magnitude on the Richter scale.
