A video of an interview with Graham Price, about the superloo industry in Christchurch. Price talks about servicing portable toilets around Christchurch after the 2010 and 2011 earthquakes. The interview is part of the 'Spilling the Beans' video series which examines the extraordinary lives of ordinary people in Christchurch.
A video of an interview with David Stanley, Director of Canterbury Biltong, about the company's experiences after the 2010 and 2011 earthquakes. This video is part of The Press's 'Up and Running' series, showcasing businesses which have stayed up and running despite the challenges posed by the 2010 and 2011 Canterbury earthquakes.

Damaged seating in the QEII stadium. The photographer comments, "This is the QEII stadium in Christchurch. During the 22 February earthquake the stadium was severely damaged and looks like it will be demolished. Anyone in Bay 3 would have no need of the toilet after this happened".
An old advertising sign exposed by the demolition of an adjoining building. The photographer comments, "'Protect your investment. Paint your property regularly - and save money. Polson's decorators and sign writers.' The building that was adjacent to this one was demolished after the Christchurch earthquake and revealed this fabulous old wall sign.
A digitally manipulated image of an excavator demolishing a house. The photographer comments, "My neighbour I thought was going to be one of the first to be rebuilt in the area after being damaged in the 22 February 2011 earthquake, but the builders have knocked it down and not returned yet".

A photograph of the inside of a fridge in a flat on Poplar Street taken during the Residential Access Project. The project gave residents temporary access within the red-zone cordon in order to retrieve items from their homes. The contents of the fridge have gone mouldy after being left in there for three weeks.
A video of an interview with landscape architect Di Lucas, about her vision for the Christchurch rebuild. Lucas talks about the need to build light buildings by using light materials such as timber. The video is part of The Press's 'Christchurch, one year after February 22, 2011' series.
A photograph of the former site of the Locke family's house at 392 Oxford Terrace. The Locke's house was deconstructed after their land was zoned Red. The photographer comments, "The house was deconstructed and rebuilt on another site". Grass has grown over the site.
A photograph of 386 and 378 Oxford Terrace, taken from across the road. The former site of Doug Sexton's house is on the right, behind the wire fence. Sexton's house was demolished after his land was Red zoned.
A photograph of the former site of a house at 57 Bangor Street. The house was demolished after the land was zoned Red. The houses in the background have also been demolished, so that Oxford Terrace is visible in the distance.
Photograph captioned by Fairfax, "Earthquake damage in central Christchurch after a 6.3 earthquake. Al Nisbet, cartoonist at The Press, emerges from the rubble that collapsed over the desk he took shelter under as the earthquake hit. The debris is from the floor above that pancaked, killing one Press employee".
A photograph of the former site of the house at 466 Oxford Terrace, taken from the site next door. The house was demolished after the land was zoned Red. Wire fencing has been placed around the site as a cordon.

A portaloo ouside an apartment building, on the wall next to it is a red sticker, informing the public the site is dangerous and not to enter. On the other side are spray painted codes left by USAR after it had been cleared. This system was used following the February earthquake to mark buildings that have been checked.

The result of the magnitude 7.1 earthquake at 4.35am on September 4th 2010. The ballustrade of these buildings collapsed onto the Victorian veranda crushing it. Taken 20 days after the quake. Colombo Street in Sydenham, Christchurch - looking towards the City Centre.
All this is "red zone" after the earthquakes and has to be demolished. The roof of my "old" house (now owned by the government) can be seen between the third and fourth river-side houses.

Predicting building collapse due to seismic motion is critical in design and more so after a major event. Damaged structures can appear sound, but collapse under following major events. There can thus be significant risk in decision making after a major seismic event concerning the safe occupation of a building or surrounding areas, versus the unknown impact of unknown major aftershocks. Model-based pushover analyses are effective if the structural properties are well understood, which is not valid post-event when this risk information is most useful. This research combines Hysteresis Loop Analysis (HLA) structural health monitoring (SHM) and Incremental Dynamic Analysis (IDA) methods to determine collapse capacity and probability of collapse for a specific structure, at any time, a range of earthquake excitations to ensure robustness. The nonlinear dynamic analysis method presented enables constant updating of building performance predictions using post-event SHM results. The resulting combined methods provide near real-time updating of collapse fragility curves as events progress, quantifying the change of collapse probability or seismic induced losses for decision-making - a novel, higher resolution risk analysis than previously available. The methods are not computationally expensive and there is no requirement for a validated numerical model. Results show significant potential benefits and a clear evolution of risk. They also show clear need for extending SHM toward creating improved predictive models for analysis of subsequent events, where the Christchurch series of 2010-2011 had significant post-event aftershocks after each main event. Finally, the overall method is generalisable to any typical engineering demand parameter.
