Which mechanism amplifies ground motion during an earthquake as seismic waves reach a sedimentary basin?

💡 Explanation

When seismic waves enter a sedimentary basin characterized by layers of soil and soft rock, constructive interference of reflected waves occurs because the basin's shape focuses and amplifies energy, prolonging shaking duration. Therefore constructive interference results, rather than liquefaction resonance, velocity reduction or damping, which involve different geological properties.
