A photograph of a Christchurch City Council red sticker. The sticker was used by the Civil Defence after the 2010 and 2011 earthquakes to indicate that a building had been inspected and that serious structural damage had been found. The sticker states that there should be no entry to the building. It also states that 'entry may result in death or injury'.

Two men chat over the fence about the state of their houses after the 4th September earthquake in Christchurch. One of them is complaining about the slow pace of reconstruction of houses after the magnitude 7.1 earthquake on 4 September 2010; the second man thinks they are doing their best. Context - Frustration over the slow rate of processing insurance applications and building inspections after the magnitude 7.1 earthquake on 4 September 2010 which although it resulted in a lot of damage, no-one died. In the cartoon the man's red sticker (meaning the house is uninhabitable) has faded to green after being put on the house after the September earthquake. Three days after this cartoon was published the much more disastrous earthquake of the 22nd February struck and many people died. Quantity: 1 digital cartoon(s).

TJ's Kazbah, New Brighton After the Christchurch Earthquake (2)

Images, UC QuakeStudies

Damage to TJ's Kazbah in New Brighton. The east and north walls and part of the upper floor have collapsed, tipping rubble and the contents of the rooms out onto the street. The photographer comments, "The occupants of the business and rooms all managed to escape alive. A digger was used to make the building safe and then used to sift through the rubble for any surviving belongings. It was a very emotional time for the ex-occupants".

Geotechnical Aspects of the 22 February 2011 Christchurch earthquake

Research papers, University of Canterbury Library

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.

The damaged Knox Church on Bealey Avenue. The brick walls have collapsed, exposing the wooden structure beneath. The photographer comments, "Bealey Avenue is open to traffic, as are many of the side streets, and the damage to buildings along this street is quite impressive and perhaps just a small taste of the damage that lies beyond the cordon ... At the Hagley Park end of Bealey Avenue lies the Knox Church. This church suffered in the first earthquake and featured in the news a fair bit at the time. It's crazy to think that all that appeared to be damaged then were some bricks that had fallen from near the roof. Now, Knox Church is all but a wooden frame holding up a roof. It's eerie to drive past this large church and be able to look straight through it to trees on the other side".
