Can you please explain how is clay a better soil for constructing in seismic prone zone?

@charmigajjar62 This is a common point of confusion. The question is specifically about liquefaction susceptibility, not which soil has the highest overall bearing capacity or shear strength under normal conditions. Clay performs better in seismic zones with respect to liquefaction because its cohesive particles resist the buildup of excess pore water pressure during earthquake shaking. In contrast, loose granular soils such as sands and gravels can lose their shear strength when saturated and subjected to seismic vibrations, causing them to behave like a liquid. For this reason, clay soils are generally considered the least susceptible to liquefaction, even though some granular soils may exhibit higher shear strength under other conditions.
