Liquefaction

The video explains how mud can emerge from the ground due to liquefaction, a process where solid soil behaves like a liquid under certain conditions, such as during an earthquake. This phenomenon is more common in wet, sandy soils. The video details how earthquakes cause the soil to lose its structure, leading to flooding and damage. It also highlights efforts by engineers to develop techniques to prevent such occurrences in the future.
