How the Great Pyramid of Giza has survived 4,500 years of Egyptian earthquakes

The Conversation · · 912 words · By Colin Caprani; Scott Menegon

The article discusses a recent study on the Great Pyramid of Giza's vibrations and its resilience to earthquakes. It argues that while the pyramid possesses favorable engineering characteristics and a frequency mismatch with the soil, this is not definitive proof of intentional ancient seismic design.
