Wet and unconsolidated substrates are uniquely susceptible to <u>liquefaction</u> during an earthquake.
Liquefaction is most likely to occur in wet, sandy and unconsolidated substrates. Soils with large grains, such as sands, don't fit together very well because they have large void spaces so they are uniquely susceptible to liquefaction during an earthquake.
Thus, in wet regions of the world, this allows more water to infiltrate the soil.
Poorly drained fine grained soils such as sandy, gravelly, and silty soils are the most susceptible to liquefaction. Damages due to liquefaction impact primarily metropolitan because of their high liquefaction vulnerability and high infrastructure density.
Hence, during an earthquake, wet and unconsolidated substrates are uniquely susceptible to liquefaction.
