What type of rock is most susceptible to soil liquefaction?

Sandy soils are most susceptible to soil liquefaction, particularly when they are saturated with water. During an earthquake or similar shaking event, the pressure from the shaking can cause the sand particles to lose their contact with each other, resulting in a temporary loss of strength and increased fluidity. This phenomenon can lead to significant ground failure and poses risks to structures and infrastructure built on such soils. Other loose, granular materials can also be susceptible, but sand is the most commonly associated type.
