Mapping areas at risk from liquefaction

A team of researchers has joined forces to investigate and find solutions to tackle one of the most devastating forms of seismic phenomena – liquefaction. Liquefaction occurs in loosely-compacted sandy soils which are fully saturated with water. Seismic vibrations…

Soil liquefaction describes a phenomenon whereby a saturated soil substantially loses strength and stiffness in response to an applied stress, usually earthquake shaking or other sudden change in stress condition, causing it to behave like a liquid.In

One of the interesting aspects of the earthquake’s impact on Christchurch has been the phenomenon of liquefaction, where soil and sand is compacted and water is forced to the surface. Liquefaction has been a feature of both Christchurch earthquakes, seen as tonnes of
