A video capturing an aftershock from the Canterbury earthquake on 22 February 2011, 1:04pm. After the 6.3 magnitude earthquake at 12:51pm, Ben Post set up his camera on a tripod and left it running. The movement of the water in the fish tank during the quake suggests that the shaking is up and down. The camera also shows this effect; due to the lightweight material of the tripod, the camera is shaken about more than the surroundings.

Text reads 'Pet of the day... ' Below is a notice tacked to a wall which has an image of a cat wearing spectacles on it. Text reads 'LOST. Large moggy, last seen roaming in Christchurch. Answers to the name of "Gerry" or "Dinners ready". Has a loud purr, looks cuddly but can turn...' Context: This is a reference to Gerry Brownlee, the Minister for Earthquake Recovery. When National announced its offer based on the 2007 rating valuation to red-zone property owners on 23 June, Gerry Brownlee specifically told people who had made improvements between the time of the valuation and the September quake to 'keep their receipts'. The offer from CERA dated August 19 now says quite clearly that people can only seek an adjustment to the purchase price if the rating valuation is based on an incorrect floor area, or if 'you have received a code compliance certificate for consented building work undertaken after the rating valuation and that work increased the floor area of your house'.

The cartoon shows two images of cars nose-down in ditches, the first is caused by 'liquifaction' and the second by 'stupifaction'. Context: there was another large aftershock on Boxing Day in Christchurch which resulted in quite a lot of liquefaction. There is always concern over the Christmas holidays about drinking while driving. Other Titles - Liquefaction Quantity: 1 digital cartoon(s).

The Old Lyttelton Post Office, opened in 1874, showing damage after a series of earthquakes hit Christchurch and Lyttelton over the last 9 months. In the shadow of a broken house, Down a deserted street, Propt walls, cold hearths, and phantom stairs, And the silence of dead feet — Locked wildly in one another's arms I saw two lovers meet. ...

Currently there is a worldwide renaissance in timber building design. At the University of Canterbury, new structural systems for commercial multistorey timber buildings have been under development since 2005. These systems incorporate large timber sections connected by high strength post-tensioning tendons, and timber-concrete composite floor systems, and aim to compete with existing structural systems in terms of cost, constructability, operational and seismic performance. The development of post-tensioned timber systems has created a need for improved lateral force design approaches for timber buildings. Current code provisions for seismic design are based on the strength of the structure, and do not adequately account for its deformation. Because timber buildings are often governed by deflection, rather than strength, this can lead to the exceedence of design displacement limitations imposed by New Zealand codes. Therefore, accurate modeling approaches which define both the strength and deformation of post-tensioned timber buildings are required. Furthermore, experimental testing is required to verify the accuracy of these models. This thesis focuses on the development and experimental verification of modeling approaches for the lateral force design of post-tensioned timber frame and wall buildings. The experimentation consisted of uni-direcitonal and bi-directional quasi-static earthquake simulation on a two-thirds scale, two-storey post-tensioned timber frame and wall building with timber-concrete composite floors. The building was subjected to lateral drifts of up to 3% and demonstrated excellent seismic performance, exhibiting little damage. The building was instrumented and analyzed, providing data for the calibration of analytical and numerical models. Analytical and numerical models were developed for frame, wall and floor systems that account for significant deformation components. The models predicted the strength of the structural systems for a given design performance level. The static responses predicted by the models were compared with both experimental data and finite element models to evaluate their accuracy. The frame, wall and floor models were then incorporated into an existing lateral force design procedure known as displacement-based design and used to design several frame and wall structural systems. Predictions of key engineering demand parameters, such as displacement, drift, interstorey shear, interstorey moment and floor accelerations, were compared with the results of dynamic time-history analysis. It was concluded that the numerical and analytical models, presented in this thesis, are a sound basis for determining the lateral response of post-tensioned timber buildings. However, future research is required to further verify and improve these prediction models.

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 woman sits reading a newspaper with reports about the Japanese earthquake and the latest news on Christchurch post-earthquake. Her husband has just put a Jerry Lee Lewis record on the turntable and the song 'Whole lotta shakin' goin' on' is playing; he says Didn't I always say this guy was ahead of his time?' Context - The Christchurch earthquakes of September 4 2010 and February 22 2011 as well as the Japanese earthquake and tsunami of 11 March 2011. Quantity: 1 digital cartoon(s).
