Which soil mechanics consequence reduced ziggurat stability during seasonal Mesopotamian flooding?

💡 Explanation

When ziggurats were built on silt-rich soil and subjected to seasonal flooding, increased pore water pressure caused liquefaction because the soil lost its shear strength under cyclic loading. Therefore liquefaction led to instability, unlike erosion, cracking, or swelling which stem from different moisture-related mechanisms.
