I'm referring to the Great Pyramid of Giza in Egypt. Despite a couple of large earthquakes, they haven't wrecked the Great Pyramid. It has outlived every other one of the 7 Ancient Wonders of the ancient world. The ground shakes—the pyramid shrugs. That's because every other ancient wonder was tall, decorative, & made of slender columns, statues, or marble. The Great Pyramid is the opposite: it took 2.3 million stone blocks to construct. These blocks vary in size; many weigh 2-3 tons, & some weigh 10-125 tons. The granite beams in the King's Chamber weigh 50-70 tons. The total mass of the pyramid is roughly 6 million tons. The pyramid took 20-27 years to complete during the reign of Pharaoh Khufu, around 2600 BCE. That means workers placed an average of 800 blocks per day, or 1 block every 2 minutes for 20+ years straight. Thousands of workers (not slaves) were operating simultaneously, quarrying, shaping, transporting, lifting & placing. This block-by-block approach is one reason the Great Pyramid is the only ancient wonder still standing.

It outlived the Hanging Gardens of Babylon; the Statue of Zeus in Olympia, Greece; the Temple of Artemis at the ancient city of Ephesus in Türkiye; the Mausoleum at Halicarnassus, located at present-day Bodrum, Türkiye; the ancient Colossus of Rhodes, Greece; & the Lighthouse of Alexandria, Egypt. All of those collapsed, but the two significant earthquakes that struck the Great Pyramid—a 6.8 in 1847 and a 5.9 in 1992—were able to withstand any structural damage. The Great Pyramid is short, wide & incredibly heavy. The shape is basically a giant stone mountain, not a tall, narrow, or flexible building. Think of an earthquake like shaking a table. A glass of water sloshes a lot; a bag of sand barely moves. The ground has one natural vibration speed (frequency). The pyramid has a totally different one because it's extremely heavy, extremely stiff & extremely wide. When two things vibrate at different frequencies, they don't amplify each other. This is why the pyramid avoids resonance—the dangerous situation where shaking matches a building's natural rhythm & makes it wobble harder.

The pyramid has a huge base (about 13 acres/5.3 hectares), a low center of gravity & sloping sides that push downward & outward. When the ground shakes, the forces travel through the pyramid like water flowing down a ramp—they spread out instead of concentrating. Inside the Great Pyramid are the King's Chamber, the Queen's Chamber, the Grand Gallery, multiple relieving chambers & many small voids & corridors. (I have actually visited.) It turns out these chambers interrupt the solid mass, creating places where energy can bounce around, lose strength, & change direction. Think of them like shock-absorbing pockets inside a giant stone block. A completely solidified block would transmit shaking more directly.

The pyramid's internal layout breaks up the vibrations. The main job of these chambers is to redirect the crushing weight of millions of tons of stone away from the Royal Chambers' ceiling. Ancient engineers were practical: build it strong enough, but not absurdly strong. That's because earthquakes are rare in Egypt, so making them stronger would have been wasteful. Modern engineers still study the 4,600-year-old pyramids' ancient tricks. The Great Pyramid is still more earthquake-resistant than any contemporary structure, despite the use of steel, concrete, computer simulations, base isolators, and tuned mass dampers by modern engineers.

It's not that modern engineers should build skyscrapers shaped like pyramids, but the principles are still relevant because they demonstrate that geometry matters as much as materials, mass distribution can prevent resonance, voids can prevent shaking, friction can be a dampening mechanism, & lower-rise, wider-based structures are inherently more stable. But modern engineers still use shape-based stability, mass distribution & energy-dissipating voids & friction interfaces. The Egyptians didn't know about physics, but the effects match modern engineering.

Modern engineers use pyramid-like geometry in earthquake-resistant embankments, dams, bunkers, seismic foundations & tsunami barriers. The ancient pyramid avoids resonance (modern engineers still obsess over this). Resonance is when shaking matches a building's natural rhythm, making it wobble harder. Modern engineers spend millions designing buildings to avoid resonance using tuned mass dampers, flexible joints, base isolators & frequency-shifting materials. The pyramid did this naturally. The pyramid's internal voids act like shock absorbers. Modern engineers use the same idea with hollow-core concrete, seismic voids, energy-dissipating cavities & shock-absorbing architectural gaps. The 4th "trick" modern engineers picked up from ancient Egyptian engineers is stone-on-stone friction, which is a natural damping system. Modern engineers use friction dampers, sliding bearings & granular damping systems.

So why do modern buildings still collapse—like in Venezuela's recent earthquake? Because modern buildings are tall, narrow, cheaply built, made with brittle materials, constructed without proper seismic codes, many built on unstable soil, not designed to avoid resonance, & not designed with damping systems. Many modern buildings—especially in regions with limited resources—do not.

Today, there are not many modern buildings that have survived earthquakes, except for Japan's Tokyo Skytree, standing 2,080 feet (634 m) high, which withstood a magnitude of 9.0. But it survived because it had a central column that acts like a tuned mass damper. The whole tower is designed to sway safely, & it uses flexible steel instead of brittle materials. This is one of the strongest modern earthquake-resistant structures ever built. The Tokyo Tower survived multiple quakes, including a 9.0 magnitude one in 2011. The Transamerica Pyramid in San Francisco survived the 1989 Loma Prieta M6.9 quake. This building directly copied the Great Pyramid geometry.
