How are buildings made earthquake proof?

Answer 1

Simple buildings can just be made with a strong frame or base so the whole thing moves as one piece instead of collapsing.

For bigger constructions you can build in vibration absorbers. Some are similar to shock absorbers on a car with a spring and damper system. Others can use systems with big tanks of water or heavy masses tuned to the natural frequencies of the building so the movement transmitted into the device prevents a destructive resonance building up the amplitude of the building’s movement.
