Regional Earthquake Hazard and Risk Assessment Studies (ECan)

Environment Canterbury undertook regional earthquake hazard and risk assessment studies between 1997 and 2008. The main purpose of the studies was to quantify the earthquake hazard from faults within and near Canterbury, and to quantify the earthquake risk (incorporating hazard and consequences). See Collection Overview for background and usage information.

Collection Overview: Regional Earthquake Hazard and Risk Assessment Studies
Collection Overview: Regional Earthquake Hazard and Risk Assessment Studies
Environment Canterbury's overview of their Regional Earthquake Hazard and Risk Assessment Studies.
Earthquake hazard and risk assessment study: options and issues
Earthquake hazard and risk assessment study: options and issues
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. See Object Overview for background and usage information.

Earthquake hazard and risk assessment study Stage 1 Part A: Earthquake source identification and characterisation
Earthquake hazard and risk assessment study Stage 1 Part A: Earthquake source identification and characterisation
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.

Earthquake hazard and risk assessment study Stage 1 Part B: Probabilistic seismic hazard assessment and earthquake scenarios for the Canterbury region, and historic earthquakes in Christchurch
Earthquake hazard and risk assessment study Stage 1 Part B: Probabilistic seismic hazard assessment and earthquake scenarios for the Canterbury region, and historic earthquakes in Christchurch
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.

Updated probabilistic seismic hazard assessment for the Canterbury region
Updated probabilistic seismic hazard assessment for the Canterbury region
This study updated the 1999 Earthquake hazard and risk assessment study Stage 1 Part B: Probabilistic seismic hazard assessment and Earthquake scenarios for the Canterbury region, and historic earthquakes in Christchurch report. It incorporated new fault data, a new distributed seismicity model and new methods for estimating Modified Mercalli intensities. See Object Overview for background and usage information.

Canterbury region earthquake source identification and characterisation
Canterbury region earthquake source identification and characterisation
This study updated and superseded Earthquake hazard and risk assessment study Stage 1 Part A: Earthquake source identification and characterisation (Pettinga et al, 1998). It compiled and tabulated all relevant available information on earthquake sources in Canterbury and updated the active faults database with new fault locations and information.
