A photograph of the earthquake-damaged Observatory tower at the Christchurch Arts Centre. The photograph was taken using a cellphone camera. The top of the tower collapsed during the 22 February 2011 earthquake. The rubble from the tower has been cleared and a tarpaulin has been placed over the top of the broken tower. Tyres have been placed on the tarpaulin to hold it down. A temporary roof has also been constructed over the tower to keep out the rain.

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. ...

Context - the fragility of the world from a New Zealand point of view seen in the light of the Christchurch earthquakes of 4 September 2010 and 22 February 2011 and the Japanese earthquake and tsunami of 22 February 2011 and the present threat of a nuclear catastrophe caused by damaged nuclear power plants. Quantity: 1 digital cartoon(s).

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.
