This report describes the earthquake hazard in Selwyn district and gives details of historic earthquakes. It includes district-scale (1:250,000) active fault, ground shaking zone, liquefaction and landslide susceptibility maps. The report describes earthquake scenarios for a magnitude 7.0-7.3 earthquake on the Porters Pass-Amberley Fault Zone and a magnitude 8 Alpine Fault earthquake. See Object Overview for background and usage information.

It includes district-scale (1:250,000) active fault, ground shaking zone, liquefaction and landslide susceptibility maps. The report describes earthquake scenarios for a magnitude 7.0-7.3 earthquake on the Mt Hutt-Mt Peel Fault Zone and a magnitude 8 Alpine Fault earthquake. See Object Overview for background and usage information.

Stage IV of the Christchurch liquefaction study updated the Stage II liquefaction hazard and ground damage maps with further data collected from other organisations, and included two additional maps indicating liquefaction sensitivity to groundwater levels. Stage IVa of the Christchurch liquefaction study used revised groundwater levels and adjustments to the liquefaction prediction algorithm. The outputs of the report were liquefaction hazard and ground damage maps for both average summer (low) and average winter (high) groundwater levels. The maps produced as part of Stage IVa of the report were subsequently included in an Environment Canterbury public education poster The Solid Facts on Christchurch Liquefaction which also contained information on how liquefaction occurs and what can be done to mitigate the liquefaction hazard. Stage IV of the Christchurch liquefaction study contained a number of recommendations to improve the liquefaction potential and ground damage maps for Christchurch. See Object Overview for background and usage information.

This report describes the earthquake hazard in Waimate and Mackenzie districts and the part of Waitaki district within Canterbury, and gives details of historic earthquakes. It includes district-scale (1:500,000) active fault, ground shaking zone, liquefaction and landslide susceptibility maps. The report describes earthquake scenarios for a magnitude 7.2-7.4 Ostler Fault earthquake near Twizel, a magnitude 8 Alpine Fault earthquake, and a magnitude 6.9 Hunters Hills Fault Zone earthquake near Waimate. See Object Overview for background and usage information.

This study compiled and tabulated all relevant available information on earthquake sources (active faults) in Canterbury and mapped the fault locations onto 1:50,000 or 1:250,000 overlays on topographic maps (later digitised into the Environment Canterbury active faults database). The study also reviewed information on historic earthquakes, instrumental seismicity and paleoseismic studies and identified information gaps. It recommended an approach for a probabilistic seismic hazard analysis and development of earthquake scenarios. See Object Overview for background and usage information.
