← GeographyWhich mechanism causes increased building damage during earthquakes in areas with soft soils?
A)Liquefaction amplifying ground shaking✓
B)Resonance minimizing structural displacement
C)Diffraction reducing seismic wave energy
D)Refraction deflecting seismic waves
💡 Explanation
When seismic waves pass through saturated, loose soils, liquefaction occurs because the soil loses its shear strength, leading to amplified ground shaking and foundation failures. Therefore liquefaction amplifies shaking, rather than resonance minimization, diffraction reduction, or refraction deflection, which require different soil properties or wave interactions.
