Researchers have discovered that the Great Pyramid of Giza's unique design allows it to withstand earthquakes effectively. By vibrating at a different frequency than the surrounding soil, combined with its internal structure, the pyramid has remained stable for nearly 5,000 years despite occasional seismic activity.
- 01The Great Pyramid was built around 2600 B.C. as the tomb of Pharaoh Khufu and consists of approximately 2.3 million stone blocks.
- 02The pyramid vibrates at frequencies between 2 and 2.6 times per second, while the surrounding soil vibrates more slowly, preventing resonance.
- 03Pressure-relieving chambers above the king's chamber help distribute weight and reduce vibration strength.
- 04The study's findings were published on May 21 in Scientific Reports.
- 05The research team monitored vibrations at 37 points around and within the pyramid using disturbances from ocean waves and human activity.

The Great Pyramid of Giza, built around 2600 B.C. as the tomb of Pharaoh Khufu, has shown remarkable resilience to earthquakes over nearly 5,000 years. Researchers, led by geophysicist Mohamed ElGabry, discovered that the pyramid vibrates at a frequency of 2 to 2.6 times per second, while the surrounding soil vibrates more slowly, which helps prevent resonance that could amplify vibrations during seismic events. This unique frequency difference, along with the pyramid's sturdy design and internal pressure-relieving chambers, contributes to its stability. Notably, the pyramid has withstood significant earthquakes, including a magnitude 6.8 quake in 1847 and a magnitude 5.8 quake in 1992, with minimal damage. The study, published in Scientific Reports, highlights the engineering ingenuity of ancient Egyptians, although it remains unclear if they specifically designed the pyramid with earthquake resistance in mind. The findings may offer valuable insights for modern construction, emphasizing the importance of understanding long-lasting architectural principles.
