Question

Give scientific reasons.

The foundation of the earthquake-proof building is separated from other lands.

Answer 1

A seismic wave absorber layer is laid between the ground and the foundation of earthquake-resistant buildings. This layer absorbs the pressure exerted by the earthquake tremors on the sidewalls of the building. Due to this, the building does not shake with the same intensity as the earth is shaking. Thus, the foundation of earthquake building is separated from the ground so that it can withstand the high pressure (load) exerted by the seismic waves on its sidewalls.
