Following the 2010/2011 Canterbury earthquakes a detailed campaign of door to door assessments was conducted in a variety of areas of Christchurch to establish the earthquake performance of residential dwellings having masonry veneer as an external cladding attached to a lightweight timber framing system. Specifically, care was taken to include regions of Christchurch which experienced different levels of earthquake shaking in order to allow comparison between the performance of different systems and different shaking intensities. At the time of the inspections the buildings in the Christchurch region had been repeatedly subjected to large earthquakes, presenting an opportunity for insight into the seismic performance of masonry veneer cladding. In total just under 1100 residential dwellings were inspected throughout the wider Christchurch area, of which 24% were constructed using the older nail-on veneer tie system (prior to 1996) and 76% were constructed using screw fixed ties to comply with the new 1996 standards revision (post-1996), with 30% of all inspected houses being of two storey construction. Of the inspected dwellings 27% had some evidence of liquefaction, ground settlement or lateral spreading. Data such as damage level, damage type, crack widths, level of repair required and other parameters were collected during the survey. A description of the data collection processes and a snapshot of the analysis results are presented within. http://15ibmac.com/home/

Following the Christchurch earthquake of 22 February 2011 a number of researchers were sent to Christchurch, New Zealand to document the damage to masonry buildings as part of “Project Masonry”. Coordinated by the Universities of Auckland and Adelaide, researchers came from Australia, New Zealand, Canada, Italy, Portugal and the US. The types of masonry investigated were unreinforced clay brick masonry, unreinforced stone masonry, reinforced concrete masonry, residential masonry veneer and churches; masonry infill was not part of this study. This paper focuses on the progress of the unreinforced masonry (URM) component of Project Masonry. To date the research team has completed raw data collection on over 600 URM buildings in the Christchurch area. The results from this study will be extremely relevant to Australian cities since URM buildings in New Zealand are similar to those in Australia.

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.

A container labelled 'Chch East residents'has landed on the far side of the planet Mars. Others have landed or are descending. People in space suits exit the containers. One of them shakes hands with a green Martian commenting to him that the ground there is solid, it has nice views and the locals are a lot less alien than the insurance agents back home. Context: refers to NASA's exploration of the surface of Mars by the Curiosity rover. The rover landed on Mars in September 2012 and the ongoing problems of earthquake survivors in Christchurch's eastern suburbs. Quantity: 1 digital cartoon(s).

Shows Christchurch's Anglican cathedral receiving extensive treatment including blood, ambulances, scaffold and signs reading 'save!' In the background Christchurch's Catholic Cathedral says it wants its share of attention as well. Context: The focus of repairing the Christchurch Anglican cathedral appeared to draw focus and resources from the equally historic and damaged Catholic Cathedral. Quantity: 1 digital cartoon(s).

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.

This paper provides an overview of the salient aspects of the dense array of ground motions observed in the 4 September 2010 Darfield and 22 February 2011 Christchurch earthquakes. Particular attention is given to inferred physical reasons for the observed ground motions, which include: (i) source features such as forward directivity effects; (ii) The effects of the Canterbury Plains sedimentary basin on basin-generated surface waves, and waveguide effects through the region; and (iii) the importance of local site response as evidenced by observations of large long period amplification and liquefaction. The significance of vertical ground motion intensity is also examined.

A digitally manipulated image of a fallen headstone. The photographer comments, "Since the September 2010 earthquake in Christchurch, New Zealand a lot of the headstones have fallen, but sadly a lot have not been resurrected to their former places".

A sticker produced by SPCA Canterbury for residents to stick on their doors, indicating that there is an animal inside the property. This was produced after the 2010 and 2011 Canterbury earthquakes to help emergency personnel determine whether an animal is inside the building.

The scale of damage from a series of earthquakes across Christchurch Otautahi in 2010 and 2011 challenged all networks in the city at a time when many individuals and communities were under severe economic pressure. Historically, Maori have drawn on traditional institutions such as whanau, marae, hapu and iwi in their endurance of past crises. This paper presents research in progress to describe how these Maori-centric networks supported both Maori and non-Maori through massive urban dislocation. Resilience to any disaster can be explained by configurations of economic, social and cultural factors. Knowing what has contributed to Maori resilience is fundamental to the strategic enhancement of future urban communities - Maori and non-Maori.
