Study reveals Great Pyramid vibrates at 2.3 Hz, ground at 0.6 Hz, explaining earthquake resistance. Published in Scientific Reports on February 25, 2026 Led by Mohamed El-Gabry of Egypt's National Research Institute of Astronomy and Geophysics Researchers measured the pyramid's vibrations in ambient conditions to find its natural frequencies
A recent study in Scientific Reports found the Great Pyramid vibrates at 2.3 Hz while the ground beneath it resonates at just 0.6 Hz. Led by Mohamed El-Gabry of Egypt's National Research Institute of Astronomy and Geophysics, researchers say this frequency mismatch prevents seismic energy from efficiently transferring into the structure. This is the first time ambient vibration measurements have been used to understand the pyramid's natural frequencies. The findings reveal ancient builders may have inadvertently created a structure inherently resistant to earthquake damage. 🏛️
Key Facts
- Published in Scientific Reports on February 25, 2026
- Led by Mohamed El-Gabry of Egypt's National Research Institute of Astronomy and Geophysics
- Researchers measured the pyramid's vibrations in ambient conditions to find its natural frequencies
- The pyramid has a homogeneous frequency averaging 2.3 hertz
- The ground beneath vibrates at only 0.6 hertz
- The frequency difference means ground shaking is less likely to feed energy efficiently into the pyramid
- This is the first time such a study has been conducted on the Great Pyramid
