liquefaction correlations but the CPT has a number of advantages that have made it the primary site characterization tool in certain geologic settings. Shear wave velocity (Vs) tests, Becker Penetration Tests (BPT) and large penetrometer tests (LPT) tend to be used in special situations and thus are used less ofte Soil liquefaction occurs when waterlogged soil behaves like a liquid. Some people refer to it as earthquake liquefaction. The vibrations of earthquake shockwaves in water-saturated soils trigger the phenomenon. Earthquakes are a very common origin of soil liquefaction damage, but other vibration-creating events can be a factor Seismic Hazards. The Seismic Hazards Program delineates areas prone to ground failure and other earthquake-related hazards including soil liquefaction (the failure of water-saturated soil), earthquake-induced landslides, surface fault rupture, and tsunami inundation. Cities and counties are required to use these maps in their land-use planning. Liquefaction happens in areas which are sandy, the water table is low, which means, the soil is soft just the way it is here in Padada. One manifestation of liquefaction is when the ground. Liquefaction is a process that temporarily turns firm ground into a liquid. During the Canterbury earthquakes of September 2010 and February 2011, liquefaction caused silt and fine sand to boil up and bury streets and gardens and caused buildings and vehicles to sink. This was a new phenomenon for most New Zealanders, yet it has been a feature during earthquakes throughout this country's.
