Abstract
In recognition of the earthquake threat to Canterbury, and its statutory responsibilities, Environment Canterbury initiated a comprehensive, staged multi-year earthquake hazard and risk assessment study programme in 1997. In this paper the general framework and philosophy behind Environment Canterbury's Earthquake Hazard and Risk Assessment Programme is outlined. The results of the stage 1A earthquake source characterisation, and stage 1B probabilistic seismic hazard assessment for the Canterbury region are presented in companion papers in this volume. The programme participants have ongoing earthquake hazard research projects, and also are involved as practitioners in land-use planning and development of relevance to the Canterbury region. The coordinated programme is primarily designed to facilitate the integration of a diverse range of independent studies, so making relevant earthquake hazard and risk information readily available to a wide range of end-users, including other professionals (engineers and scientists), planners, civil defence and emergency management staff, utility operators, and developers. In addition the programme provides up to date, relevant information for public education and awareness purposes. The first stage of the programme has been completed, and includes identification and characterisation of earthquake sources, probabilistic hazard assessment, and formulation of earthquake scenarios. The long-term staged study programme will address the earthquake hazard, the risks posed, possible mitigation options and mitigation implementation methods available.
