A new study published in Scientific Reports suggests that the Great Pyramid of Giza’s remarkable earthquake resilience may be the product of deliberate ancient engineering rather than mere good fortune. Researchers from Egypt’s National Research Institute of Astronomy and Geophysics placed accelerometers at 37 locations inside and around the structure, finding that internal vibrations fell within a narrow, uniform range of 2.0 to 2.6 hertz. This means that the monument behaves as a highly cohesive structure, distributing seismic stress evenly across its mass. The frequency gap prevents the resonance effect that causes modern buildings to collapse during seismic events. Additional protection comes from the limestone bedrock foundation, weight-relief chambers above the King’s Chamber that function as natural shock absorbers, and the pyramid’s inherently stable, bottom-heavy symmetrical design. Researchers conclude that the pyramid’s architects refined their techniques across generations, learning from earlier structural failures such as the collapse of the Meidum Pyramid.
