Study Identifies Structural Features That Helped Great Pyramid Resist Earthquakes

Scientists recorded ambient vibrations at 37 locations inside and around the Great Pyramid of Giza to examine why the structure has withstood earthquakes for thousands of years. 8 in 1992. 6 hertz. The frequency difference reduced the chance that vibrations would combine and amplify, a process known as resonance.

No vibration amplification occurred in the Subterranean Chamber, which is carved directly into bedrock. Amplification increased with height and reached its highest levels in the King’s Chamber, but dropped in the Relieving Chambers directly above it. ” They noted that hard limestone used in construction may also lower seismic risk.

The study, published in the journal Scientific Reports, states that any suggestion of intentional seismic design by ancient Egyptian architects remains speculative. Researchers said future studies could examine whether the pyramid reflects early seismic engineering principles.
