Deborah Nation recalls how it was in the Sound Archives and Radio New Zealand offices in Christchurch on the day of the February earthquake. The building on the corner of Durham and Chester Street West has been condemned. Please be aware that the first sounds of this report may be upsetting, especially to listenners who experienced the earthquake.
The insurance industry says overseas insurers have become wary of New Zealand after Monday's earthquakes in Christchurch and higher premiums across the country are now almost inevitable.
Liquefaction during the 4th September 2010 Mw 7.1 Darfield earthquake and large aftershocks in 2011 (Canterbury earthquake sequence, CES) caused severe damage to land and infrastructure within Christchurch, New Zealand. Approximately one third of the total CES-induced financial losses were directly attributable to liq- uefaction and thus highlights the need for local and regional authorities to assess liquefaction hazards for present and future developments. This thesis is the first to conduct paleo-liquefaction studies in eastern Christchurch for the purpose of de- termining approximate return times of liquefaction-inducing earthquakes within the region. The research uncovered evidence for pre-CES liquefaction dated by radiocarbon and cross-cutting relationships as post-1660 to pre-1905. Additional paleo-liquefaction investigations within the eastern Christchurch suburb of Avon- dale, and the northern township of Kaiapoi, revealed further evidence for pre-CES liquefaction. Pre-CES liquefaction in Avondale is dated as post-1321 and pre-1901, while the Kaiapoi features likely formed during three distinct episodes: post-1458 and possibly during the 1901 Cheviot earthquake, post-1297 to pre-1901, and pre-1458. Evaluation of the liquefaction potential of active faults within the Can- terbury region indicates that many faults have the potential to cause widespread liquefaction within Avondale and Kaiapoi. The identification of pre-CES liquefac- tion confirms that these areas have previously liquefied, and indicates that residen- tial development in eastern Christchurch between 1860 and 2005 occurred in areas containing geologic evidence for pre-CES liquefaction. Additionally, on the basis of detailed field and GIS-based mapping and geospatial-statistical analysis, the distribution and severity of liquefaction and lateral spreading within the eastern Christchurch suburb of Avonside is shown in this study to be strongly in uenced by geomorphic and topographic variability. This variability is not currently ac- counted for in site-specific liquefaction assessments nor the simplified horizontal displacement models, and accounts for some of the variability between the pre- dicted horizontal displacements and those observed during the CES. This thesis highlights the potential applications of paleo-liquefaction investigations and ge- omorphic mapping to seismic and liquefaction hazard assessments and may aid future land-use planning decisions.
Environmental assessment in New Zealand is governed by the provisions of the Resource Management Act (RMA) 1991. The Act requires persons wishing to undertake certain activities to apply for resource consent from their local or regional council - a procedure termed the Resource Consent Process. The key component of a resource consent application is an Assessment of Environmental Effects (AEE) report; a statement of the environmental effects of a proposed activity. Problems arise when environmental assessments are complicated by uncertain and abnormal circumstances such as natural hazards. Natural hazards (including earthquakes, floods, tsunami, and coastal erosion) can be catastrophic to an environment. If hazards are not avoided or successfully mitigated, they can result in serious consequences to proposed development and to the environment which the proposal relates. The aim of this study is to assess the adequacy of the resource consent process (as outlined in the Resource Management Act 1991) for dealing with proposed development affected by natural hazards. This study reviews the context of the resource consent process for dealing with natural hazards to identify potential issues in the assessment process. Guidance criteria for assessing natural hazards (termed Natural Hazard Assessment) are developed to evaluate against two resource consent applications affected by natural hazards. The findings of the consent process review and case study evaluation are discussed to determine the adequacy of the consent process for dealing with natural hazards. From the review of the consent process it was evident that the process has a number of problems for accommodating natural hazards into the assessment. Although many important traits are provided for in the process, such traits are not always reflected in environmental assessments. Evaluation of two resource consent applications against the process of Natural Hazard Assessment (NHA) showed that these consent applications did not adequately detail key information relating to natural hazards. Many problems evident in these applications were not amended by the Consent Authorities in the review process and subsequently consent was granted to information-deficient applications. Problematic issues identified in this study include: • A distinct lack of guidance (legal or otherwise) for the applicant and Consent Authority regarding the boundaries of inclusion of an effect; • Deficiencies in planning documents are reflected in AEE reports, the review of the consent application and in the end-decision; • Under-utilisation of "experts" throughout the consent process; • Minimal identification and account for the degree of uncertainty throughout the consent process; • Resource consents are being granted even though information in consent applications, and the means for assessing the information is deficient. These issues reflect that decisions are not being made based on all elements involved in a potential hazard. Subsequently, the resource consent process is not adequate for dealing with all aspects of natural hazards. The Natural Hazard Assessment process provides educated assessment criteria to assess development affected by natural hazards. By accounting for the problems evident in the consent process, the introduction of a three-tier identification, risk and vulnerability assessment, and evaluation process to account for uncertainties, Natural Hazard Assessment provides a platform for a thorough assessment of natural hazards. The application of the principles of Natural Hazard Assessment to the consent applications affected by natural hazards showed that many key issues were not covered in the assessment under the consent process. The nature of a natural event is that one may not occur in a given region over many lifetimes, however they will occur at some stage and planning and environmental assessment needs to provide for the associated hazards. Implementation of Natural Hazard Assessment is needed to help provide answers for the problems experienced in the resource consent process. Natural Hazard Assessment would allow decision-makers to make informed judgements on the situation at hand, leading to better planning and land-use options. Change to current practice is needed, as following the current path of environmental assessment will be the hazard in the end.
