Text at top left reads 'Don't forget rubbish day' The cartoon is a large wheelie bin stacked high with debris from 'old dunger buildings'. Someone in a damaged house nearby says 'Good riddance!' 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. Earthquake Recovery Minister Gerry Brownlee may or may not have actually used the words 'old dungers' to describe some of Christchurch's heritage buildings that are not worth keeping but he might as well have done because many people believe that this is the way he thinks. Debate about which heritage buildings should be kept and which demolished has begun along with debate about how the city should be rebuilt. Quantity: 1 digital cartoon(s).

Topics - the latest twist in the Kim Dotcom saga is that the police have announced they're investigating the Government Communications Security Bureau's illegal surveillance of the internet mogul. New research has shown that membership of all mainstream Christian denominations has fallen to historic lows - except for Catholicism. New research has uncovered the role underground rock structures played in stopping the September 2010 Christchurch earthquake from linking up with the Port Hills faultline and causing greater damage to Christchurch.

Seismic retrofitting of unreinforced masonry buildings using posttensioning has been the topic of many recent experimental research projects. However, the performance of such retrofit designs in actual design level earthquakes has previously been poorly documented. In 1984 two stone masonry buildings within The Arts Centre of Christchurch received posttensioned seismic retrofits, which were subsequently subjected to design level seismic loads during the 2010/2011 Canterbury earthquake sequence. These 26 year old retrofits were part of a global scheme to strengthen and secure the historic building complex and were subject to considerable budgetary constraints. Given the limited resources available at the time of construction and the current degraded state of the steel posttension tendons, the posttensioned retrofits performed well in preventing major damage to the overall structure of the two buildings in the Canterbury earthquakes. When compared to other similar unretrofitted structures within The Arts Centre, it is demonstrated that the posttensioning significantly improved the in-plane and out-of-plane wall strength and the ability to limit residual wall displacements. The history of The Arts Centre buildings and the details of the Canterbury earthquakes is discussed, followed by examination of the performance of the posttension retrofits and the suitability of this technique for future retrofitting of other historic unreinforced masonry buildings. http://www.aees.org.au/downloads/conference-papers/2013-2/

The Townsend Observatory is located in the Arts Centre of Christchurch, in what used to be Canterbury College (now University of Canterbury). The Townsend telescope itself is a historic 6-inch Cooke refractor built in 1864 for early Christchurch colonist, Mr James Townsend, and gifted by him to Christchurch College in 1891. At the same time, the Canterbury Astronomical Society handed over its funds to the College to help erect an observatory. The College used this, and money it had set aside for a medical school, to build a biological laboratory with an attached observatory tower, which was completed in 1896. The Biology Building and Observatory Tower was the last major design by architect Benjamin Mountfort. Mr Walter Kitson was appointed custodian of the telescope and regular public open nights commenced. and continued until 2010, with the telescope being operated by students of the Department of Physics and Astronomy, University of Canterbury. The Observatory Tower was badly damaged in the 4 September 2010 earthquake and collapsed in the 22 February 2011 earthquake. The telescope was badly damaged by the collapse, but, amazingly, the optics were found entirely intact. The Department of Physics and Astronomy plans to restore the Townsend Telescope so that it can be returned to a replica Observatory Tower in its central city home, enabling the people of Christchurch, and visitors, to enjoy views of the night sky through this beautiful and historic telescope once again.

The Amuri Earthquake of September 1, 1888 (magnitude M = 6.5 to 6.8) occurred on the Hope River Segment of the Hope Fault west of Hanmer Plains. The earthquake was felt strongly in North Canterbury and North Westland and caused considerable property damage and landsliding in the Lower Hope Valley. However, damage reports and the spatial distribution of felt intensities emphasize extreme variations in seismic effects over short distances, probably due to topographic focusing and local ground conditions. Significant variations in lateral fault displacement occurred at secondary fault segment boundaries (side-steps and bends in the fault trace) during the 1888 earthquake. This historical spatial variation in lateral slip is matched by the Late Quaternary geomorphic distribution of slip on the Hope River Segment of the Hope Fault. Trenching studies at two sites on the Hope Fault have also identified evidence for five pre-historic earthquakes of similar magnitude to the 1888 earthquake and an average recurrence interval of 134 ± 27 years between events. Magnitude estimates for the 1888 earthquake are combined with a. strong ground motion attenuation expression to provide an estimate of potential ground accelerations in Amuri District during-future earthquakes on the Hope River Segment of the Hope Fault. The predicted acceleration response on bedrock sites within 20 km of the epicentral region is between 0.23 g and 0.34 g. The close match between the historic, inferred pre-historic and geomorphic distribution of lateral slip indicates that secondary fault segmentation exerts a strong structural control on rupture propagation and the expression of fault displacement at the surface. In basement rocks at depth the spatial variations in slip are inferred to be distributed within zones of pervasive cataclastic shear, on either side of the fault segment boundaries. The large variations in surface displacement across fault segment boundaries means that one must know the geometry of the fault in order to evaluate slip-rates calculated from individual locations. The average Late Quaternary slip-rate on the Hope Fault at Glynn Wye Station is between 15.5 mm/yr and 18.25 mm/yr and the rate on the subsidiary Kakapo Fault is between 5.0 mm/yr and 7.5 mm/yr. These rates have been determined from sites which are relatively free of structural complication.

Text reads 'Could the wrecking ball be used on structures outside Christchurch?' The cartoon shows Minister for the Reconstruction of Christchurch Gerry Brownlee as the wrecking ball on a crane; he says 'let the fun begin'. To one side is a large house crowded with people which represents 'the welfare state' and is surrounded by a barrier on which are printed the words 'Fiscal emergency'. Context - Gerry Brownlee is seen by many as rather too quick to demolish heritage buildings in his rush to rebuild Christchurch. The wrecking ball idea also suggests that the National government is likely to wreck the welfare state in its efforts to sort out economic problems. Quantity: 1 digital cartoon(s).

A local developer is looking to reshape Ashburton's triangle, the historic retail centre of the town. Robert Grice owns a number of buildings on Victoria Street that require earthquake strengthening and he wants to redevelop the existing shops into a new mixed use hospitality precinct named The Ash. Jonathan also discusses an attempt to add quarter of a million dollars to ECan's annual plan budget which has been labelled a "slap in the face" by Environment Canterbury councillor Ian Mackenzie. And a hold-up of plumbing parts and red tape at the border means the Staveley Ice Rink won't be open to skaters and curlers until at least mid-June.

Christchurch's historic Theatre Royal will reopen for business in November, with bookings about to open for the first show, the Royal New Zealand Ballet season of "A Christmas Carol" The 106-year old theatre has been closed for almost four years because of earthquake damage in the 2010 and 2011 earthquakes. The $40million rebuild and restoration project will be completed over the next five months and on 17 November 2014, the 'Grand Old Lady' of New Zealand theatre will reopen her doors for performances. With so few venues for performance left in the city, including the Town Hall out of commission indefinitely, the rebuild of the Theatre Royal is very good news for Christchurch audiences Chief executive Neil Cox explains the process of getting oldest Edwardian theatre in the country back in use and mounting the large scale theatrical productions it has been famous for.
