Liquefaction is a phenomenon that occurs in soils due to water pressure. It is a complex phenomenon; a detailed study will require a much greater knowledge of soil mechanics (there are modules on this in Part 2).
Some videos explaining liquefaction, and some of its effects, can be found in the player below. All files can be downloaded by right clicking on the playlist entries.
