Reconnaissance reports have highlighted the poor performance of non-ductile reinforced concrete buildings during the 2010-11 Canterbury earthquakes. These buildings are widely expected to result in significant losses under future earthquakes due to their seismic vulnerability and prevalence in densely populated urban areas. Wellington, for example, contains more than 70 pre-1970s multi-storey reinforced concrete buildings, ranging in height from 5 to 18 storeys. This study seeks to characterise the seismic performance and evaluate the likely failure modes of a typical pre-1970s reinforced concrete building in Wellington, by conducting advanced numerical simulations to evaluate its 3D nonlinear dynamic response. A representative 9-storey office building constructed in 1951 is chosen for this study and modelled in the finite element analysis programme DIANA, using a previously developed and validated approach to predict the failure modes of doubly reinforced walls with confined boundary regions. The structure consists of long walls and robust framing elements resulting in a stiff lateral load resisting system. Barbell-shaped walls are flanked by stiff columns with sufficient transverse reinforcement to serve as boundary regions. Curved shell elements are used to model the walls and their boundary columns, for which the steel reinforcement is explicitly modelled. Line elements are used to model the frame elements. The steel reinforcement in each member is explicitly modelled. The floor slabs are modelled using elastic shell elements. The model is analysed under short and long duration ground motions selected to match site specific targets in Wellington at the DBE and MCE intensity levels. The observed response of the building including drift profiles at each intesity level, strain localization effects around wall openings, and the influence of bidirectional loading are discussed.

A video about the reactions of animals at the Orana Wildlife Park to the 22 February 2011 earthquake. The video includes an interview with Nieka George, Primate Keeper, about the reaction of the spider monkey Jackie Chan, who had arrived from Wellington Zoo three days prior. It also includes an interview with Aaron Gilmore, Head Keeper of Exotic Mammals, about the reactions of the giraffes. Both species were initially alarmed by the earthquakes, but have got used to them quickly and have barely reacted to the aftershocks in the following weeks.

A video of a presentation by Haydn Read, Programme Director of Smart City Coalition, at the 2016 Seismics in the City Conference. The presentation is titled, "Smart City/Choice City".The abstract for the presentation reads, "'We want to get to the point where people can get amazing information in real-time that helps them make choices about where to swim or what road to take' (Vicki Buck, Deputy Mayor of Christchurch). Real time information and feedback via the Internet of Things. The CCC is now part of Land Information New Zealand's (LINZ) Smart City coalition which aims to test the value of smart city concepts through a series of projects in Christchurch, Auckland, and Wellington."Note that due to technical issues, the final part of this presentation was not recorded.

The 1995 book, “Wellington after the quake: the challenge of rebuilding cities”, is reviewed in light of the 2010/2011 Canterbury, New Zealand, earthquakes. Lessons are drawn related to the difficulties of recovery of complex infrastructure systems after disasters.
