A year after the first earthquake on 4 September 2010, aftershocks continue to be felt in Canterbury, and they're not always seismic ones. When buildings collapse or are cordoned off, or even just closed for repairs - what happens to the lives and livelihoods of those who used to fill them with noise and energy? Kris Vavasour returns to Lyttelton to catch up with performers and friends, to hear about life in an altered landscape.
International Red Cross Manager Bob McKerrow talks with Deborah Nation about his long career spent helping others. Bob is no stranger to disaster but it's a new experience to see the sufferings of his earthquake-hit home-town of Christchurch.
Between demolition and rebuild stands a time of opportunity in the earthquake ravaged city of Christchurch. Greening the Rubble and Gap Filler are temporary pockets of enterprise which began as early responses and have built in momentum to define the new city.
At least five companies are busy working in and around Christchurch blasting rock on unstable slopes in the hope of reducing danger since the earthquakes. Spectrum's Deborah Nation joins backcountry construction company Solutions 2 Access, as the team blasts rock on the Port Hills above Lyttelton.
With half his life work destroyed by earthquakes, Christchurch conservator Graham Stewart is on a mission to save what is left of Canterbury's remarkable stained glass history.
Stonemason Mark Whyte puts sculpting commissions aside in order to respond to the Christchurch earthquakes and save classic street facades from the 1870s. Across the Red Zone and 3 generations of the Aires family- Bob, Rob and Suzie are at work on the Heritage Hotel which were the old government buildings.
Since the Christchurch earthquakes propelled Paul Fleming from his Chancery Lane shop in central Christchurch, he has begun a business called 'Happy Tours' featuring an immaculate Austin Seven called Myrtle. Myrtle takes Spectrum's Deborah Nation into Christchurch's central city Red Zone. Christchurch poet Helen Jacobs also tours in Myrtle.
'Rekindle' is an initiative started since the earthquakes in Canterbury which provides purposeful work for young people by giving them the opportunity to design and fashion furniture from waste wood. Spectrum's Deborah Nation explores 'Rekindle'.

High demolition rates were observed in New Zealand after the 2010-2011 Canterbury Earthquake Sequence despite the success of modern seismic design standards to achieve required performance objectives such as life safety and collapse prevention. Approximately 60% of the multi-storey reinforced concrete (RC) buildings in the Christchurch Central Business District were demolished after these earthquakes, even when only minor structural damage was present. Several factors influenced the decision of demolition instead of repair, one of them being the uncertainty of the seismic capacity of a damaged structure. To provide more insight into this topic, the investigation conducted in this thesis evaluated the residual capacity of moderately damaged RC walls and the effectiveness of repair techniques to restore the seismic performance of heavily damaged RC walls. The research outcome provided insights for developing guidelines for post-earthquake assessment of earthquake-damaged RC structures. The methodology used to conduct the investigation was through an experimental program divided into two phases. During the first phase, two walls were subjected to different types of pre-cyclic loading to represent the damaged condition from a prior earthquake, and a third wall represented a repair scenario with the damaged wall being repaired using epoxy injection and repair mortar after the pre-cyclic loading. Comparisons of these test walls to a control undamaged wall identified significant reductions in the stiffness of the damaged walls and a partial recovery in the wall stiffness achieved following epoxy injection. Visual damage that included distributed horizontal and diagonal cracks and spalling of the cover concrete did not affect the residual strength or displacement capacity of the walls. However, evidence of buckling of the longitudinal reinforcement during the pre-cyclic loading resulted in a slight reduction in strength recovery and a significant reduction in the displacement capacity of the damaged walls. Additional experimental programs from the literature were used to provide recommendations for modelling the response of moderately damaged RC walls and to identify a threshold that represented a potential reduction in the residual strength and displacement capacity of damaged RC walls in future earthquakes. The second phase of the experimental program conducted in this thesis addressed the replacement of concrete and reinforcing steel as repair techniques for heavily damaged RC walls. Two walls were repaired by replacing the damaged concrete and using welded connections to connect new reinforcing bars with existing bars. Different locations of the welded connections were investigated in the repaired walls to study the impact of these discontinuities at the critical section. No significant changes were observed in the stiffness, strength, and displacement capacity of the repaired walls compared to the benchmark undamaged wall. Differences in the local behaviour at the critical section were observed in one of the walls but did not impact the global response. The results of these two repaired walls were combined with other experimental programs found in the literature to assemble a database of repaired RC walls. Qualitative and quantitative analyses identified trends across various parameters, including wall types, damage before repair, and repair techniques implemented. The primary outcome of the database analysis was recommendations for concrete and reinforcing steel replacement to restore the strength and displacement capacity of heavily damaged RC walls.
Almost 1 million artefacts were discovered in a 'big dig' after the Christchurch earthquakes in 2010 and 2011.
Over 4000 people have reported feeling the quake.
Since the Christchurch earthquakes 15 years ago archeologists have been busy. They've dug up nearly a million artifacts, unearthing and illuminating the city's history.
