This paper discusses the seismic performance of the standard RC office building in Christchurch that is given as a structural design example in NZS3101, the concrete structures seismic standard in New Zealand. Firstly the push-over analysis was carried out to evaluate the lateral load carrying capacity of the RC building and then to compare that carrying capacity with the Japanese standard law. The estimated figures showed that the carrying capacity of the New Zealand standard RC office building of NZS3101:2006 was about one third of Japanese demanded carrying capacity. Secondly, time history analysis of the multi-mass system was performed to estimate the maximum response story drift angle using recorded ground motions. Finally, a three-dimensional analysis was carried out to estimate the response of the building to the 22nd February, 2011 Canterbury earthquake. The following outcomes were obtained. 1) The fundamental period of the example RC building is more than twice that of Japanese simplified calculation, 2) The example building’s maximum storey drift angle reached 2.5% under the recorded ground motions. The main purpose of this work is to provide background information of seismic design practice for the reconstruction of Christchurch.

The Canterbury region of New Zealand experienced four earthquakes greater than MW 6.0 between September 2010 and December 2011. This study employs system dynamics as well as hazard, recovery and organisational literature and brings together data collected via surveys, case studies and interviews with organisations affected by the earthquakes. This is to show how systemic interactions and interdependencies within and between industry and geographic sectors affect their recovery post-disaster. The industry sectors in the study are: construction for its role in the rebuild, information and communication technology which is a regional high-growth industry, trucking for logistics, critical infrastructure, fast moving consumer goods (e.g. supermarkets) and hospitality to track recovery through non-discretionary and discretionary spend respectively. Also in the study are three urban centres including the region’s largest Central Business District, which has been inaccessible since the earthquake of 22 February 2011 to the time of writing in February 2013. This work also highlights how earthquake effects propagated between sectors and how sectors collaborated to mitigate difficulties such as product demand instability. Other interacting factors are identified that influence the recovery trajectories of the different industry sectors. These are resource availability, insurance payments, aid from central government, and timely and quality recovery information. This work demonstrates that in recovering from disaster it is crucial for organisations to identify what interacting factors could affect their operations. Also of importance are efforts to reduce the organisation’s vulnerability and increase their resilience to future crises and in day-to-day operations. Lastly, the multi-disciplinary approach to understanding the recovery and resilience of organisations and industry sectors after disaster, leads to a better understanding of effects as well as more effective recovery policy.

The Prime Minister Chris Hipkins today announced an additional three hundred and one million dollar boost for the rebuild of earthquake damaged Christchurch schools, and said the programme in Christchurch may be a template for repairing flood damaged schools in the North Island. Some schools are still waiting to be repaired more than a decade after the devastating quakes. On his first visit to Christchurch since becoming Prime Minister, Chris Hipkins visited one of the schools still in the midst of its rebuild process, and to celebrate the progress being made. Our reporter Rachel Graham and videographer Nate McKinnon went along.

A photograph of the base of the Townsend Telescope, still attached to a piece of rubble. The rubble is from the Observatory tower at the Christchurch Arts Centre. The tower collapsed during the 22 February 2011 earthquake and the rubble spilled into the courtyard in front. A digger was used to clear the rubble away from the building.

A photograph of the earthquake damage to the Christchurch Chinese Methodist Church on Papanui Road. The gable walls have crumbled, bricks spilling onto the ground. The tower has been removed and braced on the ground in front. Cordon fencing has been placed around the building. Parts of the fence have been decorated with hearts and the word 'love'.

Motoko Kakubayashi joins us from Toyko where they are also about to mark a significant anniversary. A few weeks after the 2011 Christchurch earthquake, a magnitude 9.0 earthquake hit the east coast of Japan, triggering a tsunami that destroyed large parts of the coast, including damage to the Fukushima Dai-ichi Nuclear Power Plant. More than 15,000 lives were lost, more than 2000 still remain missing. In one afternoon, half a million people became homeless, and the search for family and friends at evacuation shelters began.

A digitally manipulated image of a statue of the Virgin Mary in a broken window of the Cathedral of the Blessed Sacrament. The photographer comments, "Before the February 2011 earthquake the statue above was facing into the Cathedral looking down a corridor, but after it had turned 180 degrees to point towards the window. The statue of Mary turning like this gave a sign of hope for the people of Christchurch. It was amongst one of the most photographed things after the earthquake until it was removed".
