Liquefaction is a phenomena that appears in not very cohesive soils. There are many factors linked to the existence of quicksand. Holtz, Kovacs, and Sheahan describe how the seepage forces, liquefaction, earthquakes, soil stress and underground water table are crucial elements to the understanding of quicksand. Additionally, the book provides practical methods to understand liquefaction and how it has affected engineering structures around the world.
“If the seepage forces are large enough, the effective stress can go to zero and the soil becomes essentially a dense liquid called quicksand. Another important consequence is liquefaction caused by vibrations from earthquakes and other dynamic sources.” (294)

The scientists based their research on a bead sinking experiment and mathematical data related to sand, clay and salt water quicksands. Moreover, they explained that the phenomena was related to the viscosity and density of the quicksand and the sinking body. Khaldoun, Eiser and Wegdam determined that under an extremely low viscosity and density, the sinking object, would fall to the bottom. Beads and humans have a very close density value. Therefore, they concluded that it is impossible to completely sink beads and humans with a density of 1
