What Happened to This Car?

The video explains the phenomenon of liquefaction, which caused the sinking of Port Royal after an earthquake. Liquefaction occurs when waterlogged sandy soil loses its stability during seismic activity, turning into a quicksand-like state. This process can lead to the sinking of structures and vehicles. The video also demonstrates how liquefaction can be experienced at a beach and discusses its implications during earthquakes.
