Implementing seismic risk mitigation is a major challenge in many earthquake prone regions. The objective of this research is to investigate how property investment market practices can be used to enhance building owners’ decisions to improve seismic performance of earthquake prone buildings (EPBs). A case study method adopted, revealed the impacts of the property market stakeholders’ practices on seismic retrofit decisions. The findings from this research provide significant new insights on how property market-based incentives such as such as mandatory disclosure of seismic risks in all transactions in the property market, effective awareness seismic risk program and a unified earthquake safety assessment information system, can be used to enhance EPBs owners seismic retrofit decisions. These market-based incentives offer compelling reasons for the different property market stakeholders and the public at large to retain, care, invest, and act responsibly to rehabilitate EPBs. The findings suggest need for stakeholders involved in property investment and retrofit decisions to work together to foster seismic rehabilitation of EPBs.

Earthquakes and other major disasters present communities and their authorities with an extraordinary challenge. While a lot can be done to prepare a city’s response in the event of a disaster, few cities are truly prepared for the initial impact, devastation, grief, and the seemingly formidable challenge of recovery. Many people find themselves overwhelmed with facing critical problems; ones which they have often never had experience with before. While the simple part is agreeing on a desired outcome for recovery, it appears the argument that exists between stakeholders is the conflicting ideas of How To effectively achieve the main objective. What I have identified as an important step toward collaborating on the How To of recovery is to identify the ways in which each discipline can most effectively contribute to the recovery. Landscape architecture is just one of the many disciplines (that should be) invovled in the How To of earthquake recovery. Canterbury has an incredible opportunity to set the benchmark for good practice in earthquake recovery. To make the most of this opportuntiy, it is critical that landscape architects are more effectively engaged in roles of recovery across a much broader spectrum of recovery activities. The overarching purpose of this research is to explore and provide insight to the current and potential of landscape architects in the earthquake recovery period in Canterbury, using international good practice as a benchmark. The research is aimed at stimulating and guiding landscape architects dealing with the earthquake recovery in Canterbury, while informing stakeholders: emergency managers, authorities, other disciplines and the wider community of themost effective role(s) for landscape architects in the recovery period.

Health correspondent Karen Brown visited Christchurch Hospital a week after the disaster that resulted in patients being resuscitated by torchlight. She reviews the immediate impact of the earthquake on the region's health services, how they’re picking themselves up and what lies ahead.

The 4th of September 2010 Mw 7.1 Darfield (Canterbury) earthquake had generated significant ground shaking within the Christchurch Central Business District (CBD). Despite the apparently significant shaking, the observed structural damage for pre-1970s reinforced concrete (RC) buildings was indeed limited and lower than what was expected for such typology of buildings. This paper explores analytically and qualitatively the different aspects of the "apparent‟ good seismic performance of the pre-1970s RC buildings in the Christchurch CBD, following the earthquake reconnaissance survey by the authors. Damage and building parameters survey result, based on a previously established inventory of building stock of these non-ductile RC buildings, is briefly reported. From an inventory of 75 buildings, one building was selected as a numerical case-study to correlate the observed damage with the non-linear analyses. The result shows that the pre-1970s RC frame buildings performed as expected given the intensity of the ground motion shaking during the Canterbury earthquake. Given the brittle nature of this type of structure, it was demonstrated that more significant structural damage and higher probability of collapse could occur when the buildings were subjected to alternative input signals with different frequency content and duration characteristics and still compatible to the seismicity hazard for Christchurch CBD.
