Researchers Explain Why the Great Pyramid of Giza Has Endured for Millennia
The Great Pyramid of Giza has stood for over 4,500 years, defying time and natural forces. Researchers have now identified a key factor in its durability: the way the pyramid interacts with seismic vibrations.
A study published in the Journal of the Egyptian Society of Archaeometry found that the pyramid and the soil beneath it vibrate at different frequencies. This mismatch in vibrational characteristics means that seismic energy is partially reflected back into the ground rather than being transmitted fully into the structure. The design choices made by ancient builders—including the pyramid's mass distribution and broad base—further helped dissipate earthquake forces.
Researchers used both physical modeling and computational simulations to arrive at these findings. The results help explain not only the pyramid's survival but also why certain ancient structures have endured while others have not.
