During many years the analysis of some geophysical results of Charles Darwin was being carried out in Department. Darwin has connected almost 200 years ago results of catastrophic earthquakes with vertical movement of a surface of the Earth. Usually this movement less horizontal movement and its influence on destruction of cities is not considered. Earthquake hazard assessment studies were focused usually on the horizontal ground motion. Effects of the strong vertical motion were not, practically, discussed. The margins of safety against gravity-induced static vertical forces in constructed buildings usually provide adequate resistance to dynamic forces induced by the vertical acceleration during an earthquake. However, the earthquake in Christchurch is an example of the vertical seismic shock . The earthquake magnitude was rather small - nearby 6.3. However, the result was catastrophic. The same took place in 1835. It allowed to Darwin to formulate a few great ideas. Charles Darwin has explained qualitatively results of an interaction of huge seismic waves with volcanoes and the nature of volcanism and seismicity of our planet. These important data of Charles Darwin became very actual recently. It is possible to tell also the same about tsunami and extreme ocean waves described by Charles Darwin. Therefore this data were analyzed using modern mechanics, mathematics and physics in Department. In particular, the theory of catastrophic waves was developed based on Darwin's data. The theory tried to explain occurrence, evolution and distribution the catastrophic waves in various natural systems, since atoms, oceans, surfaces of the Earth and up to the very early Universe. Some results of the research were published in prestigious magazines. Later they were presented in two books devoted to Charles Darwin's anniversary (2009). Last from them was published in Russian (2011). We give here key ideas of this research which is a part of interdisciplinary researches of Department. Some ideas are discussed. Not less important purpose is very short historical review of some researches of Darwin. In particular, we underline Darwin' priority in the formulation of the bases of Dynamics Earth.

The paper discusses modelling of cyclic stress-strain behaviour of soil, in particular a simple model that can produce a desired stiffness and hysteretic damping for a given strain level as observed in laboratory testing is formulated. The unloading-reloading relationship is developed for total stress seismic site response analysis with appropriate damping at large strain. The constitutive model employs a hyperbolic equation as the backbone curve, and uses a modification of the extended Masing unloading-reloading relationship leading to correct measured modulus reduction and damping curves simultaneously. A quasi-static cyclic loading of increasing amplitude is used to demonstrate the model’s performance and its capability to allow improved modelling of the magnitude of energy dissipation based on an experimental program on native sandy soils from Christchurch, New Zealand.

A protest sign painted on a fence shows a bulldozer labelled "Govt." driven by a woman (presumably representing Education Minister Hekia Parata) running over a sheep labelled "Chch schools", next to the words "Every time you close a school you have to build a jail - Mark Twain." The photographer comments, "Due to the earthquakes in Christchurch and parents leaving the area to give their children a quieter and more education friendly life a lot of the local schools especially in the East of Christchurch are to be closed or amalgamated. This was a decision by the government without consultation with any other authorities. Mark Twain actually said 'Every time you stop a school, you will have to build a jail'".

The focus of this paper is to identify potential benefits of community involvement in master planning in the post-earthquake recovery context in Christchurch; and to identify considerations for planners involved in the design of master planning processes that involve the community. Findings are based on the results of an information sharing event on these topics convened by The Habitat Project in December 2011, and a review of the relevant literature.

A laminated sign for the 2011 Festival of Flowers attached to a wooden planter. The plants in the planter are dry and dead. The photographer comments, "The theme for the 2011 Festival of Flowers was 'burst! of water'. The Christchurch February earthquake came and water and sand called liquefaction burst out of the ground all around the area. Ironically the plants for the festival were left unattended in the cordoned off red zone and they would have loved a little burst of water".

A digitally manipulated image of two chairs sitting among rubble. The photographer comments, "There is a strip of land that has been declared as the red zone. This means that the houses facing towards the tidal estuary must be abandoned as they are on land that has been declared uneconomic to repair after the Christchurch earthquakes. These chairs are at the front of one of these properties that will be bulldozed. These seem to be saying come hell or high water we will not be moved".

Organisations locate strategically within Business Districts (CBDs) in order to cultivate their image, increase their profile, and improve access to customers, suppliers, and services. While CBDs offer an economic benefit to organisations, they also present a unique set of hazard vulnerabilities and planning challenges for businesses. As of May 2012, the Christchurch CBD has been partially cordoned off for over 14 months. Economic activity within the cordoned CBD, which previously contained 6,000 businesses and over 51,000 workers, has been significantly diminished and organisations have been forced to find new ways of operating. The vulnerabilities and resilience of CBDs not only influences outcomes for CBD organisations, but also the broader interconnected (urban/regional/national) system. A CBD is a hub of economic, social, and built infrastructure within a network of links and nodes. When the hub is disrupted all of the people, objects, and transactions that usually flow into and out of the hub must be redirected elsewhere. In an urban situation this means traffic jams in peripheries of the city, increased prices of commercial property, and capital flight; all of which are currently being faced in Canterbury. This report presents the lessons learned from organisations in CBDs affected by the Canterbury earthquakes. Here we focus on the Christchurch CBD; however, several urban town centres were extensively disrupted by the earthquakes. The statistics and discussion presented in this report are based on the results of an ongoing study conducted by Resilient Organisations (www.resorgs.org.nz). The data was captured using two questionnaire surveys of Canterbury organisations (issued November 2010 and May 2011), interviews with key informants, and in-depth case studies of organisations. Several industry sectors were sampled, and geographic samples of organisations in the Christchurch CBD, Lyttelton, and the Kaiapoi town centre were also collected. Results in this report describing “non-CBD organisations” refer to all organisations outside of the Christchurch CBD, Lyttelton, and Kaiapoi town centres.

Depending on their nature and severity, disasters can create large volumes of debris and waste. Waste volumes from a single event can be the equivalent of many times the annual waste generation rate of the affected community. These volumes can overwhelm existing solid waste management facilities and personnel. Mismanagement of disaster waste can affect both the response and long term recovery of a disaster affected area. Previous research into disaster waste management has been either context specific or event specific, making it difficult to transfer lessons from one disaster event to another. The aim of this research is to develop a systems understanding of disaster waste management and in turn develop context- and disaster-transferrable decision-making guidance for emergency and waste managers. To research this complex and multi-disciplinary problem, a multi-hazard, multi-context, multi-case study approach was adopted. The research focussed on five major disaster events: 2011 Christchurch earthquake, 2009 Victorian Bushfires, 2009 Samoan tsunami, 2009 L’Aquila earthquake and 2005 Hurricane Katrina. The first stage of the analysis involved the development of a set of ‘disaster & disaster waste’ impact indicators. The indicators demonstrate a method by which disaster managers, planners and researchers can simplify the very large spectra of possible disaster impacts, into some key decision-drivers which will likely influence post-disaster management requirements. The second stage of the research was to develop a set of criteria to represent the desirable environmental, economic, social and recovery effects of a successful disaster waste management system. These criteria were used to assess the effectiveness of the disaster waste management approaches for the case studies. The third stage of the research was the cross-case analysis. Six main elements of disaster waste management systems were identified and analysed. These were: strategic management, funding mechanisms, operational management, environmental and human health risk management, and legislation and regulation. Within each of these system elements, key decision-making guidance (linked to the ‘disaster & disaster waste’ indicators) and management principles were developed. The ‘disaster & disaster waste’ impact indicators, the effects assessment criteria and management principles have all been developed so that they can be practically applied to disaster waste management planning and response in the future.

In this paper we introduce CityViewAR, a mobile outdoor Augmented Reality (AR) application for providing AR information visualization on a city scale. The CityViewAR application was developed to provide geographical information about the city of Christchurch, which was hit by several major earthquakes in 2010 and 2011. The application provides information about destroyed buildings and historical sites that were affected by the earthquakes. The geo-located content is provided in a number of formats including 2D map views, AR visualization of 3D models of buildings on-site, immersive panorama photographs, and list views. The paper describes the iterative design and implementation details of the application, and gives one of the first examples of a study comparing user response to AR and non-AR viewing in a mobile tourism application. Results show that making such information easily accessible to the public in a number of formats could help people to have richer experience about cities. We provide guidelines that will be useful for people developing mobile AR applications for city-scale tourism or outdoor guiding, and discuss how the underlying technology could be used for applications in other areas.

Two aluminium drink cans which have split open. The photographer comments, "We had around 24 cans of diet coke in the top of the fridge when the devastating 6.1 earthquake hit Christchurch in New Zealand. The shaking caused one of the front feet of the fridge to fold, which made the fridge tip forward and causing the door to open. After all the shaking the cans had already when they flew out and hit the ground a lot of them exploded. These two cans show the explosive pressure that occurred best".

A digitally manipulated image of a shop window. A vase is visible in the window, and the sillhouette of a mannequin in the background. The photographer comments, "The title came from the pot and the E on the window. This is a building that has been off limits since the Christchurch earthquake. The E was sprayed on the window by rescue teams after searching the building and finding it was empty. This is a very old wooden building that looks OK from the front, but terrible from the side as the previously adjoined building has been demolished.

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".

A poster advertising performers Maryrose Crook, Purple Pilgrims and Thje. The photographer comments, "Maryrose Crook, Purple Pilgrims, Thje. Saturday 26 Feb (2011). HSP 9PM $5. HSP stands for High Street Project. Here is the introduction for her concert 'Maryrose Crook's spectral voice and calenture tunes float through New Zealand giants, The Renderers' psychic country-punk and splatter rock, and emerge in her solo encounters with horripilated grace and filigree menace. Purple pilgrims' wraithish hymns evolve through a braided field of curled nautical drone and distant littoral roar, abstract thrums and change-rung celestial rustle'. She was supposed to perform on 26 February, but I am guessing the concert was cancelled due to the major earthquake in Christchurch on the 22nd. The horrendous quake made the venue at 84 Lichfield Street out of limits due to it being in the dangerous earthquake red zone. It looks like she next performed on the 17 May at the Loons in Lyttelton".

Large cracks run through the brick cladding of this house in Wainoni. The photographer comments, "During the numerous earthquakes in Christchurch the land which ran alongside the Avon river on Avonside Drive slumped towards the waterway. Houses which were wooden framed and had an external brick veneer started to sink into the liquefied soil. This caused the brick walls to crack, but the houses' occupants though shook up were saved by the wooden framework from the houses collapsing on them".

Digitally manipulated image of graffiti on a brick building on St Asaph Street. The graffiti depicts a sticking plaster over a broken section of the wall, with the words "I'll kiss it better". The photographer comments, "After the 22 February 2011 earthquake in Christchurch band aid plasters starting to appear in different parts of the city on damaged buildings. A year later most can still be seen. This one was once a whole plaster, but it has slowly broken up where it crossed the gap. The red bricks seen to symbolise the terrible wounds caused to the City and it's people".

Graffiti on a wooden wall depicts a child pointing at a site across the street and reads "I remember when the Kazbah was over there." The photographer comments, "A local street artist has commemorated Christchurch's deadliest earthquake. The anniversary is tomorrow. Where the photograph was taken was the site of the Ozone Hotel, which has now gone as well. For some of us who live and work in the East of Christchurch the earthquake was not what happened in the City as we were almost unaware of it. We had no water, toilets and most of all no electricity for weeks. For myself petrol was low and with tales of all the petrol stations on our side of town being damaged we could not take the chance of venturing out on severely damaged roads to find no petrol and the possibility of not getting home. We walked around and saw the damage that was local to us. TJ's Kazbah was one that stood out. A building that had a beauty with its round tower standing proud and always looked well kept - it was now collapsed. Its tower, which was once pointing towards the sky was laying on its side. It had kept its shape, but had a lightning shaped crack through it. The one thing that kept us feeling almost normal through the coming weeks was The Press our daily paper still being delivered even though the Press building and staff had suffered so badly themselves.
