A man reading a newspaper wails and sobs when he discovers that Christchurch will not be hosting any Rugby World Cup games. The newspaper is covered with real disaster news like the Japanese earthquake and potential nuclear disaster, economy problems , and 'aftershock anxiety'. Context - The Christchurch earthquakes of 4 September 2010 and 22 February 2011 that have led to the decision that because of the amount of damage to the venue plus infrastructures and accommodation for visitors the Rugby World Cup will not be played in Christchurch. Quantity: 1 digital cartoon(s).

A video of an interview with Helen and Edna Yates about their Worcester Street house which is to be demolished due to earthquake damage. The 96-year-old identical twins lived in the house for 95 years before it was damaged in the 22 February 2011 earthquake. The video includes footage of Helen and Edna visiting the house before it is demolished.

In the period between September 2010 and December 2011, Christchurch was shaken by a series of strong earthquakes including the MW7.1 4 September 2010, Mw 6.2 22 February 2011, MW6.2 13 June 2011 and MW6.0 23 December 2011 earthquakes. These earthquakes produced very strong ground motions throughout the city and surrounding areas that resulted in soil liquefaction and lateral spreading causing substantial damage to buildings, infrastructure and the community. The stopbank network along the Kaiapoi and Avon River suffered extensive damage with repairs projected to take several years to complete. This presented an opportunity to undertake a case-study on a regional scale of the effects of liquefaction on a stopbank system. Ultimately, this information can be used to determine simple performance-based concepts that can be applied in practice to improve the resilience of river protection works. The research presented in this thesis draws from data collected following the 4th September 2010 and 22nd February 2011 earthquakes. The stopbank damage is categorised into seven key deformation modes that were interpreted from aerial photographs, consultant reports, damage photographs and site visits. Each deformation mode provides an assessment of the observed mechanism of failure behind liquefaction-induced stopbank damage and the factors that influence a particular style of deformation. The deformation modes have been used to create a severity classification for the whole stopbank system, being ‘no or low damage’ and ‘major or severe damage’, in order to discriminate the indicators and factors that contribute to ‘major to severe damage’ from the factors that contribute to all levels of damage a number of calculated, land damage, stopbank damage and geomorphological parameters were analysed and compared at 178 locations along the Kaiapoi and Avon River stopbank systems. A critical liquefiable layer was present at every location with relatively consistent geotechnical parameters (cone resistance (qc), soil behaviour type (Ic) and Factor of Safety (FoS)) across the study site. In 95% of the cases the critical layer occurred within two times the Height of the Free Face (HFF,). A statistical analysis of the geotechnical factors relating to the critical layer was undertaken in order to find correlations between specific deformation modes and geotechnical factors. It was found that each individual deformation mode involves a complex interplay of factors that are difficult to represent through correlative analysis. There was, however, sufficient data to derive the key factors that have affected the severity of deformation. It was concluded that stopbank damage is directly related to the presence of liquefaction in the ground materials beneath the stopbanks, but is not critical in determining the type or severity of damage, instead it is merely the triggering mechanism. Once liquefaction is triggered it is the gravity-induced deformation that causes the damage rather than the shaking duration. Lateral spreading and specifically the depositional setting was found to be the key aspect in determining the severity and type of deformation along the stopbank system. The presence or absence of abandoned or old river channels and point bar deposits was found to significantly influence the severity and type of deformation. A review of digital elevation models and old maps along the Kaiapoi River found that all of the ‘major to severe’ damage observed occurred within or directly adjacent to an abandoned river channel. Whilst a review of the geomorphology along the Avon River showed that every location within a point bar deposit suffered some form of damage, due to the depositional environment creating a deposit highly susceptible to liquefaction.

A photograph of an earthquake-damaged building on Acton Street. The closest section of the outer wall has collapsed, the bricks and other rubble spilling onto the pavement in front. A boat which was being stored inside has toppled over and is now sticking out of the building. Several cars, also stored inside the building, are visible.

A photograph of the earthquake damage to The Burrito Company on Armagh Street. The front window has smashed, the glass spilling onto the floor and footpath outside. USAR codes have been spray-painted on the door and window to the side. A red sticker on the door indicates that the building is unsafe to enter.

A photograph of the lens of the Townsend Telescope. The lens is the most crucial component of the telescope. Despite damage to the surrounding parts, the lens was unharmed during the 22 February 2011 earthquake. Because of this, the telescope can be restored.

Former Chancellor Rex Williams addressing students inside the UCSA's "Big Top" tent. The tent was erected in the UCSA car park to provide support for students in the aftermath of the 22 February 2011 earthquake. The students have spent the day clearing liquefaction from Christchurch properties as part of the Student Volunteer Army.

As a man stands up to his knees in liquefaction as Christchurch rocks in another aftershock he reads a newspaper which has one headline reading 'More severe aftershocks in Christchurch' and a second headline that reads 'I have an unshakeable belief in New Zealanders says next Gov. Gen.'. Context - Two earthquakes and hundreds of aftershocks have hit Christchurch, the first on 4 September 2010 and a second more devastating one on 22 February 2011. The new Governor General is Lieutenant General Jerry Mateparae; he takes over the role from incumbent Sir Anand Satyanand in August 2011. Quantity: 1 digital cartoon(s).

The Cranmer Court demolition started today in Christchurch. The 1876 building was originally a Normal School and was in a derelict state in the early 1980s when it was rescued and converted into apartments. The heritage-listed building was red-stickered after the February 2011 earthquake.

An earthquake-damaged bridge, the approach to which has slumped. The photographer comments, "Due to lateral spread and the land slumping the road leading to this bridge has moved down greatly. Just imagine making the street lamps upright and how much that section of road would rise up at the end. When you go over bridges in the east side of Christchurch it is quite a climb up and a big drop down on the other side. The bridges in most cases coped very well, but not so the land leading to them".

Our programme this morning is completely devoted to the aftermath of yesterday's Christchurch earthquake. Civil Defence says rescue teams in Christchurch are still recovering people alive who have been trapped in buildings in the city overnight. The emergency department at Christchurch Hospital is extremely busy with many seriously injured people. After an emergency cabinet meeting yesterday, the Prime Minister flew to Christchurch to view the aftermath of the quake first hand. Numerous stories, some of survival, others more tragic are emerging in the aftermath of the quake.

RNZ is launching a new podcast today marking the tenth anniversary of Christchurch earthquake. It's called Fragments: Firsthand accounts of the February 2011 earthquakes. The podcast features interviews done with quake survivors recorded in the months following the devastating earthquake recorded by locals Julie Hutton and Sandra Close. RNZ checked in with some of the people Hutton and Close spoke to ten years on from the disaster. Katy Gosset produced and presented the podcast. An earlier version of this article failed to reference the work from Julie Hutton and Sandra Close.
