A video of an interview with John Laurenson, Principal at Shirley Boys' High School, about the Government announcement of a possible merger of Shirley Boys' and Christchurch Boys' High Schools. Laurenson explains that the government has retracted this statement and that Shirley Boys' will be rebuilt. He also talks about how the announcement has upset the Shirley community.

A video of a press conference with Minister of Education Hekia Parata about the Ministry's decisions for secondary schools in Christchurch. Earlier in the day Parata announced that all secondary schools will stay open, and that Avonside Girls' High School and Shirley Boys' High School will share a new site.

After years of disruption caused by the Christchurch earthquakes, two schools have finally started moving into their new state of the art facilities. Avonside Girls' High School and Shirley Boys' High School have begun moving students into their new shared but separate campus on the grounds of the old QEII Park in north New Brighton. Some of the features include, a moveable gym, bike stands with spanners and air pumps, and a rock climbing wall. It will be the first time in New Zealand two single-sex schools have been on the same site. Guyon Espiner speaks to Avonside Girls' High principal Sue Hume and Shirley Boys' High School principal John Laurenson.

On February 22, 2011, a magnitude Mw 6.2 earthquake affected the Canterbury region, New Zealand, resulting in many fatalities. Liquefaction occurred across many areas, visible on the surface as ‘‘sand volcanoes’’, blisters and subsidence, causing significant damage to buildings, land and infrastructure. Liquefaction occurred at a number of sites across the Christchurch Boys High School sports grounds; one area in particular contained a piston ground failure and an adjacent silt volcano. Here, as part of a class project, we apply near-surface geophysics to image these two liquefaction features and determine whether they share a subsurface connection. Hand auger results enable correlation of the geophysical responses with the subsurface stratigraphy. The survey results suggest that there is a subsurface link, likely via a paleo-stream channel. The anomalous responses of the horizontal loop electromagnetic survey and electrical resistivity imaging highlight the disruption of the subsurface electrical properties beneath and between the two liquefaction features. The vertical magnetic gradient may also show a subtle anomalous response in this area, however the results are inconclusive. The ground penetrating radar survey shows disruption of the subsurface stratigraphy beneath the liquefaction features, in particular sediment mounding beneath the silt ejection (‘‘silt volcano’’) and stratigraphic disruption beneath the piston failure. The results indicate how near-surface geophysics allow the characteristics of liquefaction in the subsurface to be better understood, which could aid remediation work following liquefaction-induced land damage and guide interpretation of geophysical surveys of paleoliquefaction features.

This promotional travelogue, made for the Christchurch City Council, shows off the city and its environs. Filmed at a time when New Zealand’s post-war economy was booming as it continued its role as a farmyard for the “Old Country”, it depicts Christchurch as a prosperous city, confident in its green and pleasant self-image as a “better Britain” (as James Belich coined NZ’s relationship to England), and architecturally dominated by its cathedrals, churches and schools. Many of these buildings were severely damaged or destroyed in the earthquakes of 2010 and 2011.

A video of an interview with Arts Centre CEO Andre Lovatt about the restoration of the Arts Centre after the 22 February 2011 earthquake. The video also includes a tour of the Arts Centre, including the Boys' High School swimming pool and gymnasium which was exposed after another building was demolished.

As part of a seismic retrofit scheme, surface bonded glass fiber-reinforced polymer (GFRP) fabric was applied to two unreinforced masonry (URM) buildings located in Christchurch, New Zealand. The unreinforced stone masonry of Christchurch Girls’ High School (GHS) and the unreinforced clay brick masonry Shirley Community Centre were retrofitted using surface bonded GFRP in 2007 and 2009, respectively. Much of the knowledge on the seismic performance of GFRP retrofitted URM was previously assimilated from laboratory-based experimental studies with controlled environments and loading schemes. The 2010/2011 Canterbury earthquake sequence provided a rare opportunity to evaluate the GFRP retrofit applied to two vintage URM buildings and to document its performance when subjected to actual design-level earthquake-induced shaking. Both GFRP retrofits were found to be successful in preserving architectural features within the buildings as well as maintaining the structural integrity of the URM walls. Successful seismic performance was based on comparisons made between the GFRP retrofitted GHS building and the adjacent nonretrofitted Boys’ High School building, as well as on a comparison between the GFRP retrofitted and nonretrofitted walls of the Shirley Community Centre building. Based on detailed postearthquake observations and investigations, the GFRP retrofitted URM walls in the subject buildings exhibited negligible to minor levels of damage without delamination, whereas significant damage was observed in comparable nonretrofitted URM walls.
