Site amplification refers to the phenomenon where seismic waves are intensified as they pass through different types of soil and geological materials, leading to increased ground shaking at a particular location during an earthquake. This effect is significant because it can greatly affect the level of shaking experienced at the surface, influencing building performance and damage potential. Understanding site amplification is crucial for evaluating site-specific seismic hazards and for designing structures that can withstand these amplified forces.
