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.
- peterwwillis 9y agoThis is highly dependent on the design and the size. The larger a wooden building is, the more likely a lower floor will soften and pancake during an earthquake, and structural elements need to be added to stiffen it against lateral movement. 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-building-is-still-standing https://gizmodo.com/5846501/how-japans-oldest-wooden-buildin...
