Text at top left reads 'Christchurch display portaloos' Four different styles of portaloo are shown; the "Merivale", the 'Sumner", the "Heritage" and the "Eastsider"; someone inside the 'Eastsider says 'At least I'm open plan AND mobile!' Context - After the tow Christchurch earthquakes and hundreds of aftershocks that have hit Christchurch one of the problems is lack of toilets because of damage to buildings and also damage to sewage systems so many portaloos and chemical toilets have been sent to Christchurch. However many people have resorted to the good old kiwi way and dug long-drops in the backyard. A website 'showusyourlongdrop.co.nz' has been developed by Christchurch man Jason Moore, who was inspired by photographs of Christchurch dunnies uploaded to Facebook. There has been a competition.

The globe is depicted as a hand grenade; the skeletal remains of a hand reach out to 'pull the pin'. 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.

A badly damaged house in Burwood. Parts of the house have moved in different directions, leaving walls and doors misaligned. The photographer comments, "Although this looks like an extreme wide angle shot it is actually a house tilted in every direction at the same time. The earthquake caused the ground to vibrate and compress so much that the sandy soil liquefied and caused the ground to collapse under this modern home".

Glass panels with brass surrounds, stacked inside a building. The photographer comments, "These were brass dividers that were brought inside the building two years ago after the Christchurch earthquake. They have been sitting there abandoned in a restaurant that will be either repaired and reopened at a later date or demolished like the many others of its kind".

Beverly Forrester farms near Harden which is down the road from Hanmer Springs. Road damage means she's cut off from the outside world, apart from her phone Beverly was caught up in the Christchurch earthquake, so the events of the last 24hrs have been quite trying for her.

Churches are an important part of New Zealand's historical and architectural heritage. Various earthquakes around the world have highlighted the significant seismic vulnerability of religious buildings, with the extensive damage that occurred to stone and clay-brick unreinforced masonry churches after the 2010-2011 Canterbury earthquakes emphasising the necessity to better understand this structural type. Consequently, a country-wide inventory of unreinforced masonry churches is here identified. After a bibliographic and archival investigation, and a 10 000 km field trip, it is estimated that currently 297 unreinforced masonry churches are present throughout New Zealand, excluding 12 churches demolished in Christchurch because of heavy damage sustained during the Canterbury earthquake sequence. The compiled database includes general information about the buildings, their architectural features and structural characteristics, and any architectural and structural transformations that have occurred in the past. Statistics about the occurrence of each feature are provided and preliminary interpretations of their role on seismic vulnerability are discussed. The list of identified churches is reported in annexes, supporting their identification and providing their address.

A man representing the South Island stands under an umbrella representing 'hope' to shelter from a bucketload of water representing 'misfortune'. Context - in the last year apart from the usual droughts and floods the South Island has suffered the Pike River Mine disaster on 19 November 2010 in which 29 coal miners were killed, the 7.1 earthquake on 4 September 2010 in which there was a lot of damage but no deaths and now on 22 February 2011 a 6.3 magnitude earthquake which has probably killed more than 200 people (at this point the number is still not known) and caused 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.

The cartoon's title is 'Life in the South Island'. A man wonders aloud to his wife when the 'plague of locusts' will arrive as they have had 'collapsing finance companies, earthquakes' and 'heavy snow damage'. Refers to the collapse of South Canterbury Finance, the earthquake of 4th September, and more recently, heavy snow in Southland that has caused roofs to collapse. Quantity: 1 digital cartoon(s).

The objective of this study is to examine the influence of near-fault motions on liquefaction triggering in Christchurch and neighboring towns during the 2010-2011 Canterbury earthquake sequence (CES). The CES began with the 4 September 2010, Mw7.1 Darfield earthquake and included up to ten events that triggered liquefaction. However, most notably, widespread liquefaction was induced by the Darfield earthquake and the Mw6.2, 22 February 2011 Christchurch earthquake. Of particular relevance to this study is the forward directivity effects that were prevalent in the motions recorded during the Darfield earthquake, and to a much lesser extent, during the Christchurch earthquake. A 2D variant of the Richart-Newmark fatigue theory was used to compute the equivalent number of cycles (neq) for the ground motions, where volumetric strain was used as the damage metric. This study is unique because it considers the contribution and phasing of both the fault-normal and fault-parallel components of motion on neq and the magnitude scaling factor (MSF). It was found that when the fault-normal and fault-parallel motions were treated individually, the former yielded a lower neq than the latter. Additionally, when the combined effects of fault-normal and fault-parallel components were considered, it was found that the MSF were higher than those commonly used. This implies that motions containing near-fault effects are less demanding on the soil than motions that do not. This may be one of several factors that resulted in less severe liquefaction occurring during the Darfield earthquake than the Christchurch earthquake.

A policeman and his dog stop outside a house wrecked in the Christchurch earthquake and phone for assistance saying 'Have found signs of low-life' because he can see 'Christchurch looting in progress'. 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 courage, generosity and 'can do' attitude of the people has been wonderful apart from the antisocial behaviour of a few looters and others taking advantage of the situation.

A major hazard accompanying earthquake shaking in areas of steep topography is the detachment of rocks from bedrock outcrops that subsequently slide, roll, or bounce downslope (i.e. rockfalls). The 2010-2011 Canterbury earthquake sequence caused recurrent and severe rockfall in parts of southern Christchurch. Coseismic rockfall caused five fatalities and significant infrastructural damage during the 2011 Mw 6.2 Christchurch earthquake. Here we examine a rockfall site in southern Christchurch in detail using geomorphic mapping, lidar analysis, geochronology (cosmogenic 3He dating, radiocarbon dating, optically stimulated luminescence (OSL) from quartz, infrared stimulated luminescence from K-feldspar), numerical modeling of rockfall boulder trajectories, and ground motion prediction equations (GMPEs). Rocks fell from the source cliff only in earthquakes with interpolated peak ground velocities exceeding ~10 cm/s; hundreds of smaller earthquakes did not produce rockfall. On the basis of empirical observations, GMPEs and age chronologies we attribute paleo-rockfalls to strong shaking in prehistoric earthquakes. We conclude that earthquake shaking of comparable intensity to the strongest contemporary earthquakes in Christchurch last occurred at this site approximately 5000 to 7000 years ago, and that in some settings, rockfall deposits provide useful proxies for past strong ground motions.
