Question

How do base-isolators, the rubber and steel pads under some buildings, reduce earthquake damage?


They make a building soundproof.


They absorb the energy of seismic waves.


They protect utility lines and water mains.


They prevent fires from spreading.

Answer 1

Base isolators, the rubber and steel pads placed under some buildings, primarily work by absorbing the energy of seismic waves. They are designed to decouple the building from ground motion during an earthquake, thereby reducing the amount of energy transferred to the structure. This helps to minimize seismic damage and allows the building to move somewhat independently of the ground motion.

So the correct answer is: **They absorb the energy of seismic waves.**
