Question

Quizplus · Accepted Answer

When earthquakes cause pore pressure to increase, it can result in liquefaction. This happens when the excess pore water pressure reduces the effective stress on the soil particles, causing them to separate and the soil to lose strength and stiffness. As a result, the soil becomes like a liquid, and the ground can start to flow or sink.
