Answer 2

Explanation:

It is a myth that most of the damage is done by shaking of the ground during an earthquake. But ground-shaking is a complex phenomenon. When the ground rattles beneath a building, it makes the building sway. Popular perception is that a skyscraper would be more dangerous than a smaller office building in this scenario, but in fact, the opposite is often true.

Taller structures are more flexible. They absorb earthquake vibrations by distributing them along their height. This usually lowers the impact of the earthquake. In case of shorter buildings, the force of the earthquake gets concentrated due to the lack of space to dissipate it, often resulting in collapse. For this very reason, a three-storey apartment house is considered more vulnerable to earthquake damage than a 30-storey skyscraper. Therefore, when planning earthquake resistance, shorter buildings need support elements to withstand greater forces.
