The sudden load application (or shaking) builds up the excessive pore-water pressure that detaches the soil particles from each other. The soil loses its strength at this instance, and the soil firmness reduces to zero. It behaves like a liquid.

In seismology, an earthquake rupture is the extent of slip that occurs during an earthquake in the Earth's crust. Earthquakes occur for many reasons that include: landslides, movement of magma in a volcano, the formation of a new fault, or, most commonly of all, a slip on an existing fault. http://www.seismicresilience.org.nz/topics/seismic-science-and-site-influences/earthquake-hazards/lateral-ground-displacement/ how can you catch crabs

"WebBuildings can even sink into the ground if soil liquefaction occurs. Liquefaction is the destabilization of sand or soil when groundwater (water underground) is forced out from between grains during the shaking of a moderate or strong earthquake. If liquefaction occurs under a building, it may start to lean, tip over, or sink several feet. " - Soil rupture during earthquake
