An earthquake-resistant building is reinforced so that it doesn't crumble into rubble (which allows people to escape); an earthquake-proof structure has additional features designed to protect it during sideways shifting.
How do you make a building that can withstand an earthquake?
How to Make A Building Earthquake-proof
- Create a Flexible Foundation. One way to resist ground forces is to “lift” the building's foundation above the earth through a method called base isolation. ...

Do windows break in an earthquake?
If a building has large windows, the glass may break when the ground shakes, especially if there are only narrow walls on each side of the windows. In a major earthquake, buildings with large storefront windows can lean over and even collapse if the front wall is inadequately braced.
