Thanks for the link to the video!
However here some "better" sources than Wikipedia, IMHO:
geo-net (nz) -
http://www.geonet.org.nz/earthquake/glossary.html: "# Liquefaction: A process in which water-saturated sediment temporarily loses its strength and acts as a fluid."
EQC (nz) -
http://canterbury.eqc.govt.nz/public...ative?page=0,5: "7.2 Liquefaction potential: Liquefaction occurs when geological materials lose strength and temporarily behave as a fluid during strong earthquake shaking. The potential for liquefaction depends on a number of factors including the nature of the materials (grain size, strength, and density), the depth of the susceptible materials below the ground surface, groundwater levels and pore water control along with the intensity, direction and duration of the earthquake shaking. Geologic materials most susceptible to liquefaction include saturated loose to medium dense silts and sands"
