New research on the Great Pyramid of Giza provides insight into how the structure has remained standing for more than 4,500 years despite repeated earthquakes in the region. Scientists studying the pyramid’s vibrations found that its natural frequency differs from the surrounding soil, which may help reduce the amplification of seismic shaking. Researchers also noted that the pyramid’s broad base, symmetrical shape, and strong foundation contribute to its long-term structural stability.

While experts caution that the pyramid was not necessarily designed specifically for earthquakes, the study highlights the importance of strong structural design and proper foundations in seismic performance. It also serves as another reminder that preparing buildings before a major earthquake occurs remains critical. Seismic retrofitting helps strengthen vulnerable structures, improve safety, and better protect buildings and occupants when strong shaking happens.

Where a major Hayward fault quake could shake the Bay Area hardest

The Hayward fault line has not had a major earthquake since 1868, but new simulations designed by Lawrence Livermore National Laboratory and Lawrence Berkeley National Laboratory have found the Bay Area’s geography will shape the next “big one,” trapping seismic waves in basins like Livermore Valley and amplifying the destructive energy of quakes because of the earth beneath them.
