It's almost eight years to the day since the first Christchurch earthquake, and as anyone who lives in Christchurch knows, some insurance claims are still in dispute. Dodgy repairs are still being discovered and previously undiscovered damage is being found. Earthquake Commission minister Megan Woods says as problems emerge, people can come back and ask for re-repairs or have their home looked at. But just how much money is in the National Disaster Fund?

Cracks have ripped through external columns of this 7 storey building (corner of Hereford Street / Manchester Street), and efforts are being made to shore up and strengthen it to save it from demolition after it suffered structural damage in the magnitude 7.1 earthquake that struck Christchurch on Saturday 4 September 2010.

A bus tours a city street with destroyed schools either side. The guide points out destruction on the right from earthquakes and on the left from Hekia Parata. Wider context is the ongoing impact of the Christchurch February 2011 earthquake. The implication is that the earthquake caused physical damage to some schools and that the Minister for Education is responsible for destroying others with her announcement of school closures in Christchurch on 18 February 2013.

The cartoon shows the lid of a sewer that has been dislodged allowing cockroaches labelled 'looter' to crawl out. Context - The very severe Christchurch earthquake of 22 February 2011 in which probably more than 200 people died and an enormous amount of structural damage has been done. There are inevitably people taking advantage of the fact that there are many abandoned homes which offer rich pickings. Quantity: 1 digital cartoon(s).

Shows rain falling over two gondolas of people floating past flooded Christchurch damaged houses. One person points to people in balaclavas climbing over the houses and calls out 'And look...the wildlife's returning!'. Context: Heavy rain and flooding hit Christchurch suburbs, including earthquake damaged homes (Newstalk website 14 August 2012). At the same time, wildlife (possums and rare birds) are moving into abandoned suburbs (Stuff 13 August 2012) Quantity: 1 digital cartoon(s).

Canterbury got a big shock this morning with a long and strong earthquake that sent people running for the nearest door frame. While the region seems to have escaped any major damage, it's left locals thankful it wasn't worse. The quake measured 6.0 on the richter scale and was centred 45 kilometes north of Geraldine. Since then, there have been more than 40 aftershocks. Checkpoint producer Anastasia Hedge has been near the epicentre.

The cartoon shows the hands of two people joined in mutual despair and kindness. One represents 'Christchurch' and the other the 'Pike River Mine'. Context - the 7.1 earthquake on 4 September 2010 in Christchurch in which there was a lot of damage but no deaths, the Pike River Mine disaster which occurred on the West Coast on 19 November 2010 and caused the deaths of 29 coal miners and now on 22 February 2011 a 6.3 magnitude earthquake in Christchurch which has probably killed more than 200 people (at this point the number is still not known) and caused much more severe damage. The reason the apparently lesser magnitude quake caused more destruction is because it was very shallow, was in the middle of the day and struck very close to the centre of the city. Colour and black and white versions of this cartoon are available Quantity: 2 digital cartoon(s).

Low Damage Seismic Design (LDSD) guidance material being developed by Engineering NZ is considering a design drift limit for multi-storey buildings of 0.5% at a new damage control limit state (DCLS). The impact of this new design requirement on the expected annual loss due to repair costs is investigated for a four-storey office building with reinforced concrete walls located in Christchurch. The LDSD guidance material aims to reduce the expected annual loss of complying buildings to below 0.1% of building replacement cost. The research tested this expectation. Losses were estimated in accordance with FEMA P58, using building responses from non-linear time history analyses (performed with OpenSees using lumped plasticity models). The equivalent static method, in line with NZS 1170.5 and NZS 3101, was used to design the building to LDSD specifications, representing a future state-of-practice design. The building designed to low-damage specification returned an expected annual loss of 0.10%, and the building designed conventionally returned an expected annual loss of 0.13%. Limitations with the NZS 3101 method for determining wall stiffness were identified, and a different method acknowledging the relationship between strength and stiffness was used to redesign the building. Along with improving this design assumption, the study finds that LDSD design criteria could be an effective way of limiting damage and losses.

Two men sit safe amongst the devastation of an earthquake surrounded by collapsed buildings and crushed cars; one has his head in his hands and the other says 'Remind me what we were all arguing about before all this'. Context - on 22 February 2011 a 6.3 magnitude earthquake struck in Christchurch which has probably killed more than 200 people (at this point the number is still not known) and caused very severe damage. The second man is aware of the relative unimportance of petty squabbles and differences of opinion against the enormity of the earthquake. Quantity: 1 digital cartoon(s).

A digitally manipulated image of the high diving boards at QEII swimming pool. Rubble has fallen on the boards during the demolition of the complex. A sign reads "Poseidon Extreme". The photographer comments, "I do not know what Poseidon Extreme at this swimming pool looked like before the earthquake damaged it, but it looks really radical now during it's demolition. A strange coincidence is that Poseidon is referred to as 'Earth-Shaker' due to his role in causing earthquakes. So the demolition of this pool due to the series of quakes in Christchurch all seems to be foretold by the gods and that sign".

The Canterbury earthquakes, which involved widespread damage in the February 2011 event and ongoing aftershocks near the Christchurch central business district (CBD), presented decision-makers with many recovery challenges. This paper identifies major government decisions, challenges, and lessons in the early recovery of Christchurch based on 23 key-informant interviews conducted 15 months after the February 2011 earthquake. It then focuses on one of the most important decisions – maintaining the cordon around the heavily damaged CBD – and investigates its impacts. The cordon displaced 50,000 central city jobs, raised questions about (and provided new opportunities for) the long-term viability of downtown, influenced the number and practice of building demolitions, and affected debris management; despite being associated with substantial losses, the cordon was commonly viewed as necessary, and provided some benefits in facilitating recovery. Management of the cordon poses important lessons for planning for catastrophic urban earthquakes around the world.

Depicts huge elderly woman with 'CERA' on her dress scolding smaller adult dressed as schoolboy near bustop with sign 'CBD red zone tours' Text reads 'And don't talk to strangers and don't cross the road and remember to eat your lunch..' Context: After the 22 Feburary 2011 earthquake in Christchurch, the central business district (CBD) was marked as a red zone. Red zone areas were deemed unsuitable for habitation due to significant damage and at high risk of further damage from low levels of earth shaking. CERA (Christchurch Earthquake Recovery Authority) ran public bus tours of the Christchurch CBD from November to December 2011. For safety reasons the public was not allowed off the buses as it was a dangerous and active demolition site. Quantity: 1 digital cartoon(s).
