A PDF copy of a page on the EQ Recovery Learning site which linked to a YouTube video. In 2015, Christchurch hosted the biggest international cricket tournament ever to be played in New Zealand - the ICC Cricket World Cup. Take a look behind the scenes and through the eyes of some of Canterbury's most passionate cricketers as cricket makes its epic return to the Hagley Oval.

This study determined areas of different liquefaction susceptibility in Hurunui District based mainly on geological data, with some limited borehole strata interpretation. Geotechnical data was not analysed. This was the same method used in the earthquake hazard assessments for engineering lifelines in other districts in Canterbury. Hurunui District was the first district that a hazard assessment for engineering lifelines was undertaken for (in 2000) and it did not include a liquefaction susceptibility map like the other district earthquake hazard assessments did. There are no recommendations associated with this report. 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 was the first report in the district series, and has a different format to later reports. It includes all natural hazards, not only earthquake hazards. It describes earthquake, flooding, meteorological, landslide and coastal hazards within Hurunui district and gives details of historic events. It includes district-scale (1:250,000) active fault and flood hazard maps. The report describes an earthquake scenario for a magnitude 6.9 earthquake near Cheviot, as well as flooding, meteorological, landslide, coastal erosion, storm surge, and tsunami scenarios.

This report provides information on the locations and character of active geological faults and folds in Ashburton District. The faults are mapped at a district scale and the information is intended to highlight areas where there is a risk of permanent fault movement at the ground surface, and where more detailed investigations should be done if development is proposed in that area (depending on the potential activity of the fault and the type of development proposed). See Object Overview for background and usage information. Most of the faults and folds identified at the ground surface in Ashburton District are in rural or very sparsely populated areas. In addition, most of the faults have relatively long recurrence intervals (long-term average time between fault movements) in the order of several thousand years. Following the Ministry for the Environment Active Fault Guidelines, normal residential development would be allowed on or near faults with recurrence intervals this long. There are no recommendations associated with this report. The information in the report will be reviewed as required, after the remaining district reports are completed in the region.

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.

This report assesses issues and options for preparing an earthquake hazard and risk assessment programme for Canterbury. It outlines investigation options and associated costs in order to better understand Canterbury's earthquake hazard and risk. Although earthquake hazard and risk information needs and investigation priorities within Canterbury have changed over the past 15 years, the majority of the report’s recommended components have been undertaken to some degree either by Environment Canterbury or other organisations. See Object Overview for background and usage information.

This study led on from Earthquake hazard and risk assessment study Stage 1 Part A: Earthquake source identification and characterisation (Pettinga et al, 1998). It used the location and characteristics of active faults in the Canterbury region, and the historic record of earthquakes to estimate levels of ground shaking (MM intensity, peak ground acceleration and spectral accelerations) across Canterbury for different return periods. The study also provided earthquake scenarios for selected towns and cities in Canterbury, and undertook detailed investigations into the largest historic earthquakes in Christchurch and parts of the Canterbury region. See Object Overview for background and usage information.

This report describes the earthquake hazard in Kaikoura 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 an earthquake scenario for a magnitude 7.0-7.3 Hope Fault earthquake near Kaikoura, and a subsequent local tsunami.

This report describes the earthquake hazard in Ashburton 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 Mt Hutt-Mt Peel Fault Zone and a magnitude 8 Alpine Fault earthquake.
