Which hazard increases for loose sediments during intense seismic shaking from an earthquake?

💡 Explanation

During seismic shaking, loose sediments undergo soil liquefaction because pore water pressure increases, causing a loss of shear strength, and amplifying surface wave propagation. Therefore wave amplification results, rather than reduced landslides or tsunami, which need other mechanisms, such as soil stabilization or offshore displacement.
