GeoNet is a collaboration between the Earthquake Commission and GNS Science.
Remote sensing imagery and aerial photograph datasets are available for work directly related to earthquake recovery, with some restrictions on use.

Liquefaction happens during earthquakes. The ground shaking that occurs during an earthquake can cause some soils to liquefy. This means that during an earthquake these soils will behave more like a liquid than a solid.
Christchurch liquefaction information (pdf 1.91 MB)
The liquefaction potential and liquefaction ground damage potential ratings on the Environment Canterbury liquefaction maps are only an indication of the liquefaction potential in an area, based on limited soil and water table information in the vicinity. The information is not specific to individual properties. Soil conditions in Christchurch are highly variable and actual liquefaction potential at a site can only be determined by site-specific investigations.
Zach Hill of Environment Canterbury has used GNS data to develop an animation showing the location and magnitude of Canterbury earthquakes from 4th-16th September 2010.
