In the top frames two children shout 'four point one', 'three point six', and 'five point two' and in the frame below it is seen that they are responding to bumps in the road as their mother drives through Christchurch streets. Context - The children have become expert at guessing the seismic intensity of earthquakes in Christchurch and are now applying them to bumps in the road. Colour and black and white versions available Quantity: 2 digital cartoon(s).

The cartoon shows Gerry Brownlee, the Minister for Earthquake Recovery, walking towards a spa wearing swimming togs and with a blow-up toy around his waist. Context: The cartoon illustrated an article entitled 'Sutton candid about struggles'. Cera boss Roger Sutton received politicians in the empty Centennial Park spa pool after the February earthquake when he was still head of lines company Orion. Quantity: 1 digital cartoon(s).

Text reads 'Uses for Christchurch rubble?...' The cartoon shows a bridge made partially of earthquake rubble leading from Lyttelton Harbour to Diamond Harbour on Banks Peninsula. Someone in a van says 'At long last... A bridge to Diamond Harbour!' And someone else says 'And somewhere to fish!' Context - Rubble from the earthquake may be used for the construction of watersides and bridges. This cartoon is a fanciful use for Christchurch earthquake rubble. Currently a ferry connects Diamond Harbour to Lyttelton, on the harbour's northern shore. In combination with buses from Lyttelton to downtown Christchurch, this allows residents of Diamond Bay to commute to the city. Quantity: 1 digital cartoon(s).

Text reads 'Refugees told they're not welcome in NZ...' The cartoon shows a boat full of refugees, which has tattered sails, one bearing the words 'We need a home'. A helicopter flies by and someone says 'False alarm! They're Christchurch residents trying to get out!' Context - A boat full of Sri Lanken Tamils supposedly want to come to New Zealand as refugees has been told by Prime Minister John Key that they are 'not welcome'. The pm has been accused of 'scaremongering' and that he 'has misjudged his response'. (Nelson Mail 13 July 2011). Also a reference to the plight of many people in Christchurch whose houses have been condemned by the earthquakes of 2010 and 2011. Quantity: 1 digital cartoon(s).

Much of the CBD is still cordoned off and without power (as you should be able to spot) as a result of the damage caused by February's deadly earthquake. This photo clearly shows the extent of the lean that the Hotel Grand Chancellor is now on. Apparently it is out by 1m at the top leaning east. Demolition will start about mid June and is expec...

A photograph of the earthquake damage to the Canterbury Provincial Chambers on Durham Street. One of the entrance ways has crumbled, and the rubble has fallen in front. An inner door can be seen, now leading to nowhere.

The 4th of September 2010 Mw 7.1 Darfield (Canterbury) earthquake had generated significant ground shaking within the Christchurch Central Business District (CBD). Despite the apparently significant shaking, the observed structural damage for pre-1970s reinforced concrete (RC) buildings was indeed limited and lower than what was expected for such typology of buildings. This paper explores analytically and qualitatively the different aspects of the "apparent‟ good seismic performance of the pre-1970s RC buildings in the Christchurch CBD, following the earthquake reconnaissance survey by the authors. Damage and building parameters survey result, based on a previously established inventory of building stock of these non-ductile RC buildings, is briefly reported. From an inventory of 75 buildings, one building was selected as a numerical case-study to correlate the observed damage with the non-linear analyses. The result shows that the pre-1970s RC frame buildings performed as expected given the intensity of the ground motion shaking during the Canterbury earthquake. Given the brittle nature of this type of structure, it was demonstrated that more significant structural damage and higher probability of collapse could occur when the buildings were subjected to alternative input signals with different frequency content and duration characteristics and still compatible to the seismicity hazard for Christchurch CBD.

The 22 February 2011, Mw6.2-6.3 Christchurch earthquake is the most costly earthquake to affect New Zealand, causing 181 fatalities and severely damaging thousands of residential and commercial buildings, and most of the city lifelines and infrastructure. This manuscript presents an overview of observed geotechnical aspects of this earthquake as well as some of the completed and on-going research investigations. A unique aspect, which is particularly emphasized, is the severity and spatial extent of liquefaction occurring in native soils. Overall, both the spatial extent and severity of liquefaction in the city was greater than in the preceding 4th September 2010 Darfield earthquake, including numerous areas that liquefied in both events. Liquefaction and lateral spreading, variable over both large and short spatial scales, affected commercial structures in the Central Business District (CBD) in a variety of ways including: total and differential settlements and tilting; punching settlements of structures with shallow foundations; differential movements of components of complex structures; and interaction of adjacent structures via common foundation soils. Liquefaction was most severe in residential areas located to the east of the CBD as a result of stronger ground shaking due to the proximity to the causative fault, a high water table approximately 1m from the surface, and soils with composition and states of high susceptibility and potential for liquefaction. Total and differential settlements, and lateral movements, due to liquefaction and lateral spreading is estimated to have severely compromised 15,000 residential structures, the majority of which otherwise sustained only minor to moderate damage directly due to inertial loading from ground shaking. Liquefaction also had a profound effect on lifelines and other infrastructure, particularly bridge structures, and underground services. Minor damage was also observed at flood stop banks to the north of the city, which were more severely impacted in the 4th September 2010 Darfield earthquake. Due to the large high-frequency ground motion in the Port hills numerous rock falls and landslides also occurred, resulting in several fatalities and rendering some residential areas uninhabitable.

Text across the top of the cartoon reads 'Mayor in Nepal' Christchurch Mayor Bob Parker climbs a snowy slope towards 'Mt Junket'; he is followed by sherpas carrying candles, dining table and wine glasses. Bob Parker says 'I am focused on the summit and they don't get much bigger than this!' Context - Bob Parker gave the keynote address at a United Nations-sanctioned symposium in Nepal on disaster-risk reduction. The UN and the United States Government paid Parker's costs. The disaster risk symposium featured speakers from Pakistan and Haiti - two countries struck by large earthquakes.(The Press 15 February 2011) Quantity: 1 digital cartoon(s).

Text across the top of the cartoon reads 'always design in context' There is a globe, small in the context, with a little message reading 'you are here' pointing, perhaps, to New Zealand or even more specifically, Christchurch; the globe is being threatened from all sides by forces of nature represented by the hand of god reaching out of clouds. Context - the Christchurch earthquakes of 4 September 2010 and 22 February 2011 and the idea that buildings must be designed in the context of their environment - NZ being earthquake-prone. Perhaps also the idea of 'design in context' in a broader sense. Quantity: 1 digital cartoon(s).

A photograph of members of Civil Defence and other organisations helping with the emergency response to the Canterbury earthquakes. They are standing on the corner of Montreal and Gloucester Streets outside the Christchurch Art Gallery. The Art Gallery served as the headquarters for the Civil Defence after the 22 February 2011 earthquake.
