GEOLOGY

Detailed explanation-1: -Poorly drained fine-grained soils such as sandy, silty, and gravelly soils are the most susceptible to liquefaction. Granular soils are made up of a mix of soil and pore spaces. When earthquake shock occurs in waterlogged soils, the water-filled pore spaces collapse, which decreases the overall volume of the soil.

Detailed explanation-2: -How does liquefaction occur? when the ground shakes, some areas especially those made of wet fine sand are subjected to liquefaction. considered the most dangerous type of ground failure due to liquefaction, this occurs on liquefiable slope material with steepness greater than 3 degrees.

Detailed explanation-3: -In addition to buildings, liquefaction can ruin roads, railways, airport runways, dams and anything else that sits on the ground. It can also cause damage to below-ground utilities. Liquefaction can cause landslides, settlements, and eruptions of mud or water from the ground.
