Researchers have found that the Great Pyramid of Giza possesses several structural features that have helped it withstand vibrations and earthquakes for thousands of years, Reuters reports.
An international team of scientists used seismometers to analyze vibrations at 37 points inside and around the structure. The results, published in Seismology Scientific Reports, show that the pyramid exhibits an exceptionally stable response to seismic activity.
According to the researchers, this resilience is the result of a combination of ancient Egyptian engineering choices, including a wide base, a low center of gravity, symmetrical geometry, gradual reduction of mass toward the top, and a complex internal structure with chambers that help dissipate seismic energy. The fact that the pyramid is built on solid limestone bedrock also plays a key role.
“These elements together create a well-balanced and stable structure,” said lead author, seismologist Mohamed El-Gabry.
Scientists also highlighted five chambers above the King’s Chamber, which are believed to reduce vibration transmission and amplification within the structure, protecting its most critical parts.
The pyramid has survived numerous earthquakes, including major events in 1847 and 1992, when widespread destruction occurred across the region. Despite this, it sustained only minor damage.
Researchers suggest that the ancient builders likely did not design the pyramid as earthquake-resistant intentionally, but gradually refined their construction techniques through trial and error.
Today, the Great Pyramid remains not only an engineering and architectural masterpiece, but also one of the most resilient ancient structures in the world.
