A video of an interview with Martin Bell, Managing Partner at Corcoran French, about the company's experiences after the 2010 and 2011 Canterbury earthquakes. This video is part of The Press's 'Up and Running' series which showcases businesses which stayed up and running despite the challenges posed by the 2010 and 2011 Canterbury earthquakes.

A video of an interview with Peter Townsend, Chief Executive of Canterbury Employers' Chamber of Commerce about the experiences of businesses in the aftermath of the 2010 and 2011 Canterbury earthquakes. Townsend talks about business collaboration in Christchurch, the need for businesses to have a back-up plans, the increase in people working from home, and the importance of businesses understanding their insurance. This video is part of a series about businesses in Christchurch after the earthquakes.

Lincoln University and CBRE, a commercial real estate service provider, have conducted research to investigate the impacts of the Canterbury earthquake on the commercial office market in Christchurch. The 22 February 2011 Canterbury earthquake had a devastating impact on Christchurch property with significant damage caused to land and buildings. As at January 2012, around 740 buildings have either been demolished or identified to be demolished in central Christchurch. On top of this, around 140 buildings have either been partially demolished or identified to be partially demolished. The broad aims of our research are to (i) examine the nature and extent of the CBD office relocation, (ii) identify the nature of the occupiers, (iii) determine occupier’s perceptions of the future: their location and space needs post the February earthquake, and the likelihood of relocating back to the CBD after the rebuild, and (iv) find out what occupiers see as the future of the CBD, and how they want this to look.

This paper examines the consistency of seismicity and ground motion models, used for seismic hazard analysis in New Zealand, with the observations in the Canterbury earthquakes. An overview is first given of seismicity and ground motion modelling as inputs of probabilistic seismic hazard analysis, whose results form the basis for elastic response spectra in NZS1170.5:2004. The magnitude of earthquakes in the Canterbury earthquake sequence are adequately allowed for in the current NZ seismicity model, however the consideration of ‘background’ earthquakes as point sources at a minimum depth of 10km results in up to a 60% underestimation of the ground motions that such events produce. The ground motion model used in conventional NZ seismic hazard analysis is shown to provide biased predictions of response spectra (over-prediction near T=0.2s , and under-predictions at moderate-to-large vibration periods). Improved ground motion prediction can be achieved using more recent NZ-specific models.

The sequence of earthquakes that has affected Christchurch and Canterbury since September 2010 has caused damage to a great number of buildings of all construction types. Following post-event damage surveys performed between April 2011 and June 2011, the damage suffered by unreinforced stone masonry buildings is reported and different types of observed failures are described. A detailed technical description of the most prevalently observed failure mechanisms is provided, with reference to recognised failure modes for unreinforced masonry structures. The observed performance of existing seismic retrofit interventions is also provided, as an understanding of the seismic response of these interventions is of fundamental importance for assessing the vulnerability of similar strengthening techniques when applied to unreinforced stone masonry structures.

Scientists stand before a model that will predict earthquakes. The model is a large arm attached to wires and switches with a thumb that flicks coins '"Heads" we have big quake at five-o-clock... "tails" we don't'. Context: short term predictions (hours to days) are in general unlikely to be possible, at present. Relates to the Christchurch earthquakes which experts have said could go on for years. Quantity: 1 digital cartoon(s).

The cartoon shows the word 'Christchurch' fractured by earthquake. Text above reads 'The new tear(s)'. A second version has the text in the singular 'The new tear'. Context: In spite of Christchurch's great hopes for a new year without earthquakes, there have been numerous quakes and aftershocks. A wordplay on 'new year' and 'new tear' - that is weeping with fear and dismay. Two versions of this cartoon are available Quantity: 2 digital cartoon(s).
