Which risk increases when a large earthquake causes liquefaction in loosely packed, water-saturated soil?

💡 Explanation

When an earthquake causes liquefaction, effective stress decreases because pore water pressure increases dramatically, turning soil into a quicksand-like fluid, leading to differential settlement. Therefore, building foundation settlement results, rather than pipeline corrosion, or methane release, which are unrelated or linked weak correlation; barometric alteration not likely.
