A video of a tractor on a farm near River Road in Lincoln. The tractor is making a several passes over a sand volcano with a rotary hoe. This was one of several soil-remediation techniques tested on farms affected by the 4 September 2010 earthquake.

The South New Brighton jetty has been closed for 3 or 4 years (fenced off) then the fence was removed and it was "open", but nothing has happened to it since the earthquakes, but it is closed again now, although it looks like a home made sign!

Well-validated liquefaction constitutive models are increasingly important as non-linear time history analyses become relatively more common in industry for key projects. Previous validation efforts of PM4Sand, a plasticity model specifically for liquefaction, have generally focused on centrifuge tests; however, pore pressure transducers installed at several free-field sites during the Canterbury Earthquake Sequence (CES) in Christchurch, New Zealand provide a relatively unique dataset to validate against. This study presents effective stress site response analyses performed in the finite difference software FLAC to examine the capability of PM4Sand to capture the generation of excess pore pressures during earthquakes. The characterization of the subsurface is primarily based on extensive cone penetration tests (CPT) carried out in Christchurch. Correlations based on penetration resistances are used to estimate soil parameters, such as relative density and shear wave velocity, which affect liquefaction behaviour. The resulting free-field FLAC model is used to estimate time histories of excess pore pressure, which are compared with records during several earthquakes in the CES to assess the suitability of PM4Sand.

Aerial footage of Canterbury and the Christchurch central city after the 4 September 2010 earthquake. The footage shows the earthquake damage to Homebush, St John's Church in Hororata, the railway tracks near Rolleston, and Westende Jewellers on Colombo Street. It also shows flooding in the streets of New Brighton.

A house on Acland Avenue in Avonside that has been abandoned due to damage from the 4 September 2010 earthquake. The house's front garden has become overgrown and weeds have grown up through the cracks in its driveway. Its chimneys have collapsed and have been weather proofed with tarpaulins.

A video of an interview with Andrew Holden, Editor of The Press, about the 4 September 2010 earthquake. Holden talks about the status of the Press Building in Cathedral Square, The Press's temporary offices in the Novotel hotel, and the importance of newspapers in a post-disaster zone.

A photograph of members of the Wellington Emergency Management Office at Cowles Stadium on Pages Road. The stadium was set up by Civil Defence as temporary accommodation for those displaced by the 4 September 2010 earthquake. In the background, members of Red Cross are working at the registration table.

A photograph of St John's Anglican Church in Hororata. The spire of the church, which partially collapsed in the 4 September earthquake, has been boarded up in order to protect the building from rain. This photograph was modelled off an image taken by BeckerFraserPhotos in October 2010.

St Pauls Trinity-Pacific Presbyterian Church on the corner of Cashel and Madras Streets. Scaffolding has been placed around the left dome of the building which was damaged during the 4 September earthquake. Plastic has also been placed over the dome to protect the inside from weather damage.

A photograph of mattresses in Cowles Stadium, still in their plastic wrapping waiting to be unwrapped. The stadium was set up as a Civil Defence Report Centre after the 4 September 2010 earthquake and the mattresses were to be used as beds for those displaced by the earthquake.
