Which outcome generally occurs due to increased pore water pressure during high intensity seismic activity?

💡 Explanation

Decreased effective stress will generate reduced liquefaction resistance during earthquakes because Liquefaction occurs through the mechanism of increased pore water pressure reducing the effective stress between soil particles; therefore soils lose shear strength, rather than gaining strength from seismic activity.
