Which mechanism limits development suitability within a floodplain filled with uncompacted alluvial sediments during seismic activity?

💡 Explanation

During seismic activity, uncompacted saturated alluvial sediments are prone to liquefaction because shaking increases pore water pressure, reducing the effective stress and causing the soil to behave like a liquid. Therefore liquefaction susceptibility limits development, rather than erosion, subsidence or oxidation which require different environmental or geological mechanisms.
