← GeographyWhich mechanism amplifies seismic wave intensity in basins with soft sedimentary rock fillings during an earthquake?
A)Constructive interference of reflected waves✓
B)Increased wave velocity due to density
C)Reduced damping from fluid saturation
D)Liquefaction resulting in base isolation
💡 Explanation
When seismic waves enter a sedimentary basin, constructive interference occurs because the waves reflect and superimpose, increasing amplitude and shaking intensity on the surface due to resonance. Therefore, constructive interference amplifies intensity, rather than higher velocity, reduced damping, or basal isolation which would reduce intensity.
