The underlying geological issues hidden beneath Christchurch’s swampy plains meant that the city’s founders and their surveyors who chose this site for their planned city, knew nothing …
The 22 February 2011, Mw6.2-6.3 Christchurch earthquake is the most costly earthquake to affect New Zealand, causing 181 fatalities and severely damaging thousands of residential and commercial buildings, and most of the city lifelines and infrastructure. This manuscript presents an overview of observed geotechnical aspects of this earthquake as well as some of the completed and on-going research investigations. A unique aspect, which is particularly emphasized, is the severity and spatial extent of liquefaction occurring in native soils. Overall, both the spatial extent and severity of liquefaction in the city was greater than in the preceding 4th September 2010 Darfield earthquake, including numerous areas that liquefied in both events. Liquefaction and lateral spreading, variable over both large and short spatial scales, affected commercial structures in the Central Business District (CBD) in a variety of ways including: total and differential settlements and tilting; punching settlements of structures with shallow foundations; differential movements of components of complex structures; and interaction of adjacent structures via common foundation soils. Liquefaction was most severe in residential areas located to the east of the CBD as a result of stronger ground shaking due to the proximity to the causative fault, a high water table approximately 1m from the surface, and soils with composition and states of high susceptibility and potential for liquefaction. Total and differential settlements, and lateral movements, due to liquefaction and lateral spreading is estimated to have severely compromised 15,000 residential structures, the majority of which otherwise sustained only minor to moderate damage directly due to inertial loading from ground shaking. Liquefaction also had a profound effect on lifelines and other infrastructure, particularly bridge structures, and underground services. Minor damage was also observed at flood stop banks to the north of the city, which were more severely impacted in the 4th September 2010 Darfield earthquake. Due to the large high-frequency ground motion in the Port hills numerous rock falls and landslides also occurred, resulting in several fatalities and rendering some residential areas uninhabitable.
The title is 'Gerry BrownLie?' and the cartoon shows the Minister for Earthquake recovery, Gerry Brownlee, saying 'It was NOT a lie. It was a false promise'. Context: Earthquake Minister Gerry Brownlee has apologised for falsely promising red zone homeowners they would be paid out for improvements to their house. Brownlee promised in June that, in some cases, home improvements like new kitchens would be included in the government settlement offer for red zone houses. But the offer is only valid if the improvement has added to the footprint of the house. (Press - 4 September 2011) Alternate version of DCDL-0018758 Quantity: 1 digital cartoon(s).

Questions to Ministers 1. Hon PHIL GOFF to the Prime Minister: Is he satisfied that actions to address the Christchurch earthquake are an adequate response; if not, what are his areas of concern? 2. AMY ADAMS to the Minister of Finance: What reports has he received on the economic impact of the earthquake in Christchurch on 22 February 2011? 3. Hon CLAYTON COSGROVE to the Minister for Canterbury Earthquake Recovery: Is he satisfied with the level of support being offered to the people of Christchurch in the wake of the earthquake on 22 February 2011? 4. NICKY WAGNER to the Minister for Social Development and Employment: What is the Government doing to support Canterbury businesses and employees through the earthquake recovery? 5. Hon ANNETTE KING to the Minister for Social Development and Employment: Is she confident that the Ministry of Social Development has responded adequately to the Christchurch earthquake? 6. METIRIA TUREI to the Minister of Finance: Has he considered raising a temporary levy on income to help fund the rebuilding of Christchurch; if so, how much could it raise? 7. AARON GILMORE to the Minister for Tertiary Education: What work has been done to help the families of tertiary students and tertiary institutions affected by the 22 February 2011 earthquake in Christchurch? 8. Hon JIM ANDERTON to the Minister for Canterbury Earthquake Recovery: Will he ensure that Christchurch homeowners and businesses are able to access insurance cover from existing policies or new cover they require since the 22 February 2011 earthquake? 9. Hon JOHN BOSCAWEN to the Attorney-General: Has he asked the Māori Party to agree to amendments to the Marine and Coastal Area (Takutai Moana) Bill that would make it explicitly clear that customary title holders would not be able to charge individuals for accessing a beach, and require any negotiated settlements to be referred back to Parliament for validation; if so, what response did he receive? 10.

RAHUI KATENE to the Minister for Canterbury Earthquake Recovery: Did he agree with his spokesman's response to the situation for residents in Christchurch East following the earthquake of 22 February 2011, that, "It is apparent, given the scale out there, that there just wasn't sufficient hardware out there, loos and the like", and what urgent actions have been taken to give priority to communities in the eastern suburbs? 12. COLIN KING to the Minister of Civil Defence: Why was a state of national emergency declared on 23 February 2011?
The New Zealand Kellogg Rural Leaders Programme develops emerging agribusiness leaders to help shape the future of New Zealand agribusiness and rural affairs. Lincoln University has been involved with this leaders programme since 1979 when it was launched with a grant from the Kellogg Foundation, USA.At 4.35am on 4th September 2010, Canterbury was hit by an earthquake measuring 7.1 on the Richter scale. On 22nd February 2011 and 13th June 2011 a separate fault line approximately 35km from the first, ruptured to inflict two further earthquakes measuring 6.3 and 6.0 respectively. As a direct result of the February earthquake, 181 people lost their lives. Some commentators have described this series of earthquakes as the most expensive global insurance event of all time. These earthquakes and the more than 7000 associated aftershocks have had a significant physical impact on parts of Canterbury and virtually none on others. The economic, social and emotional impacts of these quakes spread across Canterbury and beyond. Waimakariri district, north of Christchurch, has reflected a similar pattern, with over 1400 houses requiring rebuild or substantial repair, millions of dollars of damage to infrastructure, and significant social issues as a result. The physical damage in Waimakiriri District was predominately in parts of Kaiapoi, and two small beach settlements, The Pines and Kairaki Beach with pockets elsewhere in the district. While the balance of the district is largely physically untouched, the economic, social, and emotional shockwaves have spread across the district. Waimakariri district consists of two main towns, Rangiora and Kaiapoi, a number of smaller urban areas and a larger rural area. It is considered mid-size in the New Zealand local government landscape. This paper will explore the actions and plans of Waimakiriri District Council (WDC) in the Emergency Management Recovery programme to provide context to allow a more detailed examination of the planning processes prior to, and subsequent to the earthquakes. This study looked at documentation produced by WDC, applicable legislation and New Zealand Emergency Management resources and other sources. Key managers and elected representatives in the WOC were interviewed, along with a selection of governmental and nongovernmental agency representatives. The interview responses enable understanding of how central Government and other local authorities can benefit from these lessons and apply them to their own planning. It is intended that this paper will assist local government organisations in New Zealand to evaluate their planning processes in light of the events of 2010/11 in Canterbury and the lessons from WDC.
