Structural damage from seismic vibrations would be worse _______.

Question

Quizplus · Accepted Answer

Older buildings built on a thick layer of sediment are more vulnerable to seismic vibrations as the soft sediment amplifies the shaking, leading to more structural damage. Buildings made mostly of wood (A) can actually be more flexible and better at absorbing vibrations, while building codes and solid rock (C) provide some protection against seismic activity. The depth of the earthquake focus (B) can also affect the strength of seismic vibrations, but this is not the best choice in this case as it does not directly relate to building structures.
