Wooden framed houses tend to survive earthquakes better than any other construction technology, as wooden frames are flexible, especially as they're constructed with nails, which lend the frame a lot of give. Wooden houses can (from experience) survive magnitude 6-7 earthquakes. |

Japanese pagodas have very interesting designs that keep them from toppling. My favorite is the Horyu-ji pagoda. Each floor is not connected to the one above it - they're just stacked, loosely. The floors shift independently during an earthquake. A gigantic central beam in the middle acts as a tuned mass damper, preventing them from sliding off entirely. One person can make the central beam sway. https://gizmodo.com/5846501/how-japans-oldest-wooden-buildin...

Design really is everything.
