A collapsed section of the Cranmer Courts on the corner of Montreal Street and Kilmore Street. Safety fences have been erected around the building to prevent the public getting close enough to it to be endangered by falling masonry in the event of another earthquake.

A photograph of the photocopy template for the Christchurch City Council's green sticker. The sticker was used by the Civil Defence after the 2010 and 2011 earthquakes to indicate that a building had been inspected and that 'no structural or other safety hazards' were found.

This thesis investigates life-safety risk in earthquakes. The first component of the thesis utilises a dataset of earthquake injuries and deaths from recent earthquakes in New Zealand to identify cause, context, and risk factors of injury and death in the 2011 MW6.3 Christchurch earthquake and 2016 MW7.8 Kaikōura earthquake. Results show that nearly all deaths occurred from being hit by structural elements from buildings, while most injuries were caused by falls, strains and being hit by contents or non-structural elements. Statistical analysis of injured cases compared to an uninjured control group found that age, gender, building damage, shaking intensity, and behaviour during shaking were the most significant risk factors for injury during these earthquakes. The second part of the thesis uses the empirical findings from the first section to develop two tools for managing life-safety risk in earthquakes. The first tool is a casualty estimation model for health system and emergency response planning. An existing casualty model used in New Zealand was validated against observed data from the 2011 Christchurch earthquake and found to underestimate moderate and severe injuries by an order of magnitude. The model was then updated to include human behaviour such as protective actions, falls and strain type injuries that are dependent on shaking intensity, as well as injuries and deaths outside buildings. These improvements resulted in a closer fit to observed casualties for the 2011 Christchurch earthquake. The second tool that was developed is a framework to set seismic loading standards for design based on fatality risk targets. The proposed framework extends the risk-targeted hazard method, by moving beyond collapse risk targets, to fatality risk targets for individuals in buildings and societal risk in cities. The framework also includes treatment of epistemic uncertainty in seismic hazard to allow this uncertainty to be used in risk-based decision making. The framework is demonstrated by showing how the current New Zealand loading standards could be revised to achieve uniform life-safety risk across the country and how the introduction of a new loading factor can reduce risk aggregation in cities.

The partially demolished facade of the historic Blackwell's Department Store on the corner of Raven Quay and Williams Street in Kaiapoi. Black tarpaulins have been draped over the demolished section in an attempt to weather proof it, and the base of the building is enclosed in a safety fence.

A view across Worcester Street in Linwood to a block of shops, including Easy Traders Whiteware and Furniture. Masonry, structural components and the Easy Traders building's veranda have collapsed onto the road. The whole back section of the shops has also collapsed. The site is enclosed by a safety fence.
