When Edward Gibbon Wakefield developed his theory of colonisation in c.1827 (while imprisoned for abducting a young woman) he envisioned for New Zealand the formation of an idealised English rural society, in which all hard-working labourers could aspire to rural … Continue reading →
As New Zealand remembers the disaster a decade on, here is a look back at the devastation.
In the last two decades, New Zealand (NZ) has experienced significant earthquakes, including the 2010 M 7.2 Darfield, 2011 M 6.2 Christchurch, and 2016 M 7.8 Kaikōura events. Amongst these large events, tens of thousands of smaller earthquakes have occurred. While previous event and ground-motion databases have analyzed these events, many events below M 4 have gone undetected. The goal of this study is to expand on previous databases, particularly for small magnitude (M<4) and low-amplitude ground motions. This new database enables a greater understanding of regional variations within NZ and contributes to the validity of internationally developed ground-motion models. The database includes event locations and magnitude estimates with uncertainty considerations, and tectonic type assessed in a hierarchical manner. Ground motions are extracted from the GeoNet FDSN server and assessed for quality using a neural network classification approach. A deep neural network approach is also utilized for picking P and S phases for determination of event hypocentres. Relative hypocentres are further improved by double-difference relocation and will contribute toward developing shallow (< 50 km) seismic tomography models. Analysis of the resulting database is compared with previous studies for discussion of implications toward national hazard prediction models.
Today RNZ's Midday supervising producer, Denise Garland, looks at two brand new podcasts. Collapse is a podcast from Stuff, all about the Christchurch earthquakes in the lead up the to 10th anniversary of the devastating quake on February 22nd. She also looks at NZ Wars - Stories of Tainui from RNZ which over the three episodes covers the war of Waikato in the 1860s, the great war for New Zealand, a defining conflict of New Zealand.
Our weekend panellists, Jane Clifton and Richard Harman look at the 10th anniversary of the Christchurch earthquake, riding bikes on the footpath, vaccines, and the New Zealand 'terrorist' arrested at the border in Turkey.
As part of the New Zealand Archaeology Week, Clara recently gave a talk entitled, Elixirs, Ointments and Tonics: Medicine in Nineteenth Century Christchurch. This talk was part of the event, Beneath Our Feet: Archaeological Stories of Place. The talks from … Continue reading →
It’s very easy to think of 19th century New Zealand as being a place isolated from the rest of the world. Yet as we research and investigate colonial Christchurch, we are constantly being reminded of the connections that existed between … Continue reading →
As a bit of preface for this blog, for anyone not reading it on or around the 20th of August, 2021, New Zealand is back into a full lockdown and the whole country has gone a bit silly. So, in … Continue reading →
Major earthquakes, such as the Canterbury and Kaikoura events recorded in New Zealand in 2010 and 2016 respectively, highlighted that floor systems can be heavily damaged. At a reduced or full scale, quasi-static experimental tests on structural sub-assemblies can help to establish the seismic performance of structural systems. However, the experimental performance obtained with such tests is likely to be dependent on the drift protocol adopted. This paper provides an overview of the drift protocols which have been assumed in previous relevant experimental activities, with emphasis on those adopted for testing floor systems. The paper also describes the procedure used to define the loading protocol applied in the testing of a large precast concrete floor diaphragm as part of the Recast floor project at the University of Canterbury. Finally, major limits of current loading protocols, and areas of future research, are identified.
<b>Construction and Demolition (C&D) waste contributes to over 50% of New Zealand’s overall waste. Materials such as timber, plasterboard, and concrete make up 81% of the C&D waste that goes into landfills each year. Alongside this, more than 235 heritage-listed buildings have been demolished in Christchurch since the 2011 earthquakes. This research portfolio aims to find a solution to decrease C&D waste produced by demolishing heritage buildings.</b> With the recent announcement of The Cathedral of the Blessed Sacrament’s demolition, this will be another building added to the list of lost heritage in Christchurch. This research portfolio aims to bridge the relationship between heritage and waste through the recycling and reuse of the demolished materials, exploring the idea that history and heritage are preserved through building material reuse. This research portfolio mainly focuses on reducing construction and demolition waste in New Zealand, using the design of a new Catholic Cathedral as a vessel. This thesis will challenge how the construction and design industry deals with the demolition of heritage buildings and their contribution to New Zealand’s waste. It aims to explore the idea of building material reuse not only to reduce waste but also to retain the history and heritage of the demolished building within the materials.
This study analyses the success and limitations of the recovery process following the 2010–11 earthquake sequence in Christchurch, New Zealand. Data were obtained from in-depth interviews with 32 relocated households in Christchurch, and from a review of recovery policies implemented by the government. A top-down approach to disaster recovery was evident, with the creation of multiple government agencies and processes that made grassroots input into decision-making difficult. Although insurance proceeds enabled the repair and rebuilding of many dwellings, the complexity and adversarial nature of the claim procedures also impaired recovery. Householders’ perceptions of recovery reflected key aspects of their post-earthquake experiences (e.g. the housing offer they received, and the negotiations involved), and the outcomes of their relocation (including the value of the new home, their subjective well-being, and lifestyle after relocation). Protracted insurance negotiations, unfair offers and hardships in post-earthquake life were major challenges to recovery. Less-thanfavourable recovery experiences also transformed patterns of trust in local communities, as relocated householders came to doubt both the government and private insurance companies’ ability to successfully manage a disaster. At the same time, many relocated households expressed trust in their neighbours and communities. This study illuminates how government policies influence disaster recovery while also suggesting a need to reconsider centralised, top-down approaches to managing recovery.
New Zealanders are paying too much for house and contents insurance, according to a new survey. Consumer NZ's price comparison survey shows climate and natural hazard risk is being factored in, and is more expensive than ever. Quotes for a large house differed by more than $3,000 across Auckland, Hamilton, Wellington, Christchurch, and Dunedin, and there's a more than $2,000 difference between the cheapest and most expensive policies on offer for a standard-sized house. If you live somewhere with a higher chance of earthquakes - such as Wellington or Christchurch - you'll be charged more for insurance. The cost of house and contents insurance has risen by 5.6% this year, over the past ten years it's gone up 150%. Kathryn is joined by Consumer NZ's Gemma Rasmussen and Katrina Shanks Chief Executive of Financial Advice New Zealand, which represents independent and professional financial advisors.
Monday marks ten years since the Christchurch earthquake shattered New Zealand's second largest city. One-hundred-and-eighty five people lost their lives when a magnitude 6.2 quake shook the city apart. David Berry was one of the first responders in the city centre as part of Urban Search and Rescue. He speaks to Corin Dann.
Te Pae, Christchurch's near $450 million convention centre, has been officially opened this afternoon with a pōwhiri and unveiling by Mayor Lianne Dalziel and Minister Megan Woods. Billed as a legacy for the city, it replaces the old centre which was demolished following the Canterbury earthquakes. Niva Chittock is at the ceremony and joins Lisa with the details.
Sam Johnson founded the Student Volunteer Army from a Facebook page in response to the Christchurch earthquakes. Sam spoke with Karyn on air ten years ago today, and he shares his memories including how the Student Volunteer Army has grown into a nationwide movement.
Thousands of people in Christchurch and around the country paused at 12.51 on Monday afternoon to mark a decade since the February 22 magnitude 6.3 earthquake which claimed 185 lives. It was 10 years ago today when an ordinary Christchurch day turned to hell for so many. But in contrast to the harrowing scenes and sounds of that day, today a large peaceful crowd gathered at the Civic Memorial Service on the banks of the Avon River under large oak trees. Reporter Sally Murphy and cameraman Nate McKinnon were there.
In the years that have followed the devastating Christchurch earthquake, there have been many stories of the struggles people have faced. Tonight we bring you the tale of the little school in Christchurch's east that took on Wellington's big decision makers and won. Redcliffs School finally reopened last year, after spending the best part of a decade battling for its survival. Our reporter Nick Truebridge and cameraman Nate McKinnon caught up with Redcliffs' principal Rose McInerney to reflect on a tumultuous last 10 years.
Just one CTV employee who was in the building during the February 22 earthquake managed to escape before it came down. For Maryanne Jackson, the pain of losing 16 colleagues has been compounded by the lack of accountability following the catastrophic collapse that killed 141 people. She sat down with Checkpoint reporter Nick Truebridge and cameraman Nate McKinnon.
A Christchurch man with terminal cancer is using his final days to battle his insurance company, a decade on from the deadly earthquakes. Brian Shaw owns an apartment that's in a block of 11. They were all damaged in 2011. Shaw is a building consent officer. He says getting technical reports and chasing a settlement with insurer Vero has already cost the unit owners about $400,000, and they still have not even made it to court. On Friday morning he will be protesting outside Vero's Christchurch office, along with other unhappy customers.
Motoko Kakubayashi joins us from Toyko where they are also about to mark a significant anniversary. A few weeks after the 2011 Christchurch earthquake, a magnitude 9.0 earthquake hit the east coast of Japan, triggering a tsunami that destroyed large parts of the coast, including damage to the Fukushima Dai-ichi Nuclear Power Plant. More than 15,000 lives were lost, more than 2000 still remain missing. In one afternoon, half a million people became homeless, and the search for family and friends at evacuation shelters began.
Matthew McEachen should have had most of his life ahead of him when he died on February 22, 2011. The 25-year-old was a talented artist and designer, putting his skills to good use at the Southern Ink tattoo shop on Colombo St. But when the earthquake struck, Bruce, Jeanette and Sarah McEachen lost their much-loved son and older brother. Ten years on, Matti's legacy lives on. Checkpoint reporter Nick Truebridge and cameraman Nate McKinnon with his story.
A mental wellbeing programme for primary and intermediate school students will be expanded to five more district health board areas. Mana Ake started in 2018 in Canterbury and Kaikōura, and was a response to the ongoing trauma some tamariki were experiencing following the earthquakes. Now more year 1 to 8 pupils will receive extra help if they're struggling. Our reporter Kirsty Frame was at the announcement in Auckland.
In less than a minute, Christchurch and its people will be changed forever. Produced by Katy Gosset and Justin Gregory.
Little is known about The Wizard of New Zealand who took centre stage in Christchurch's Cathedral Square from the 70s until the Christchurch earthquakes in 2011, which saw the city in a state of disrepair. A man who challenged political, social and cultural ideology, The Wizard posed provocative questions in this public space, much to the delight, and sometimes dismay, of passersby. But the background to why The Wizard was there in the first place has been something of a mystery... until now. Sonia Yee finds out more in this episode of Eyewitness.
A Christchurch couple in a long running dispute over the insurance payout for their earthquake damaged home have reached an out-of-court settlement with Southern Response. The class action was brought on behalf of former AMI Insurance/Southern Response policyholders who believe the company misled them into settling their claims for less than their policies entitled them to. The lawyer for Brendan and Colleen Ross, Grant Cameron, talks to Max Towle about the settlement.
Sir Richard Hadlee is seeking public support to fund the final 1.6 million dollars needed to open an indoor training facility that will bear his name in Christchurch's Hagley Park. The multipurpose venue will cost close to 5 million to construct. It will be the first indoor cricket training facility in the city since the earthquakes, and Sir Richard hopes that it will be open in 100 days time - for the start of next year's women's cricket World Cup. Hadlee, who was diagnosed with Colorectal cancer in 2018, told Felicity Reid it's a project that he's proud to be involved in. And he's also got a few thoughts on how the Black Caps will fare in India when the first Test starts tomorrow.
After lengthy construction and Covid-19 delays, a centrepiece in Christchurch's earthquake rebuild will finally open its doors today. The $475 million convention centre called Te Pae is already booked to host 150 events next year, but they're not expected to be money-makers. Reporter Jean Edwards took a tour.
Panellists Neil Miller and Zoe George discuss a breakthrough in multi-storey buildings for earthquakes with Ben Moerman, a PHD student from the University of Canterbury studying Civil Engineering.
Victorian Authorities are warning residents of significant aftershocks following on from the magnitude 5.8 earthquake which shook Melbourne around 9am yesterday, causing significant structural damage across the city. The University of Melbourne's Dr Mark Quigley is a professor of tectonics, who became a familiar voice and face through the Christchurch quakes. Our producer Matthew Theunissen asked him how yesterday's quake compared to those he experienced in Christchurch.
The Afghanistan President has fled the country, there's chaos at the airport and streets are blocked with cars trying to leave the city, the death toll from a devastating 7-point-2-magnitude earthquake in Haiti rises to more than 700, and there are still no arrests after one teenager was killed and another two injured in a stabbing at a Christchurch party.
