The Great Pyramid of Giza, built around 4,600 years ago, has withstood significant seismic events due to advanced engineering techniques developed by ancient Egyptians. Research led by Asem Salama reveals that the pyramid's design, including its limestone foundation and vibration distribution, contributes to its remarkable stability during earthquakes.
- 01The Great Pyramid survived major earthquakes in 1847 and 1992 with magnitudes of 6.8 and 5.8, respectively.
- 02Asem Salama's research team measured vibrations at 37 locations, finding that 76% of vibrations within the pyramid were between 2.0–2.6 hertz.
- 03The pyramid's limestone foundation reduces seismic damage risk, while its Subterranean Chamber enhances resilience against underground seismic activity.
- 04The design improvements of Egyptian pyramids evolved through trial and error, refining techniques over centuries.
- 05Salama emphasizes the distinction between observed resilience and intentional seismic design, attributing the pyramid's strength to builders' engineering intuition.

The Great Pyramid of Giza, constructed approximately 4,600 years ago, has remarkably endured numerous seismic events, including earthquakes in 1847 and 1992 with magnitudes of 6.8 and 5.8. Asem Salama, a seismologist at Egypt’s National Research Institute of Astronomy and Geophysics, and his team conducted extensive research to understand the structure's resilience. Their findings, published in *Scientific Reports*, indicate that ancient Egyptians developed advanced earthquake-resistant engineering techniques over centuries.
By measuring vibrations at 37 locations within and around the pyramid, the researchers discovered that 76% of vibrations inside the structure fell between 2.0–2.6 hertz, suggesting even mechanical stress distribution. The pyramid's limestone base further minimizes seismic damage risks. Salama noted that while the pyramid's design features characteristics of excellent seismic performance, it is unclear if the builders had a formal understanding of earthquake engineering. Instead, the pyramid's resilience likely resulted from a long tradition of engineering intuition and continuous improvement, making it a remarkable architectural achievement that has influenced future generations.
