20170918_6084_7D2-41 Demolition still happening (260/365) Six ½ years after the earthquakes there are still a few demolitions taking place. This one is a block of council owned flats. Whether the whole complex is being demolished or not I don't know., but here the centre block of three is being demolished. The green grass is what was sections...
Tens of thousands of landslides were generated over 10, 000 km2 of North Canterbury and Marlborough as a consequence of the 14 November 2016, MW7.8 Kaikōura Earthquake. The most intense landslide damage was concentrated in 3500 km2 around the areas of fault rupture. Given the sparsely populated area affected by landslides, only a few homes were impacted and there were no recorded deaths due to landslides. Landslides caused major disruption with all road and rail links with Kaikōura being severed. The landslides affecting State Highway 1 (the main road link in the South Island of New Zealand) and the South Island main trunk railway extended from Ward in Marlborough all the way to the south of Oaro in North Canterbury. The majority of landslides occurred in two geological and geotechnically distinct materials reflective of the dominant rock types in the affected area. In the Neogene sedimentary rocks (sandstones, limestones and siltstones) of the Hurunui District, North Canterbury and around Cape Campbell in Marlborough, first-time and reactivated rock-slides and rock-block slides were the dominant landslide type. These rocks also tend to have rock material strength values in the range of 5-20 MPa. In the Torlesse 'basement' rocks (greywacke sandstones and argillite) of the Kaikōura Ranges, first-time rock and debris avalanches were the dominant landslide type. These rocks tend to have material strength values in the range of 20-50 MPa. A feature of this earthquake is the large number (more than 200) of valley blocking landslides it generated. This was partly due to the steep and confined slopes in the area and the widely distributed strong ground shaking. The largest landslide dam has an approximate volume of 12(±2) M m3 and the debris from this travelled about 2.7 km2 downslope where it formed a dam blocking the Hapuku River. The long-term stability of cracked slopes and landslide dams from future strong earthquakes and large rainstorms are an ongoing concern to central and local government agencies responsible for rebuilding homes and infrastructure. A particular concern is the potential for debris floods to affect downstream assets and infrastructure should some of the landslide dams breach catastrophically. At least twenty-one faults ruptured to the ground surface or sea floor, with these surface ruptures extending from the Emu Plain in North Canterbury to offshore of Cape Campbell in Marlborough. The mapped landslide distribution reflects the complexity of the earthquake rupture. Landslides are distributed across a broad area of intense ground shaking reflective of the elongate area affected by fault rupture, and are not clustered around the earthquake epicentre. The largest landslides triggered by the earthquake are located either on or adjacent to faults that ruptured to the ground surface. Surface faults may provide a plane of weakness or hydrological discontinuity and adversely oriented surface faults may be indicative of the location of future large landslides. Their location appears to have a strong structural geological control. Initial results from our landslide investigations suggest predictive models relying only on ground-shaking estimates underestimate the number and size of the largest landslides that occurred.
Tax, water and housing concerns were all debated at length by Bill English and Jacinda Ardern in last night's TVNZ leaders debate. The debate came just an hour after shock 1 News Colmar Brunton poll put Labour out in front. There have been fires and explosions at a flood damaged chemical plant near Houston forcing the evacuation of people in nearby homes. A block of flats in Aro Street has been evacuated after a large slip has come down behind it. After heavy rains and flooding a Mumbai building has collapsed, killing at least 23 people. Biosecurity officials say they expect to decide by the end of the year whether they will need to order the destruction of dairy herds to wipe out a cow disease that's broken out in the South Island. It's been revealed that not a single one of New Zealand's 315 police buildings constructed before 2011 have had a full earthquake safety check. People who've bought houses in Canterbury since the September 2010 earthquake and are still battling with insurance companies over repairs, have been told that if they want to take the matter to court, today is their last chance. The Government has begun urgent talks with Australia over the Queensland's state government's "discriminatory" trade policy which takes effect today. Trade Minister Todd McClay joins us.
There have been dramatic scenes at the America's cup in Bermuda with Team New Zealand capsizing at the start of its second race of the day against the Bristish team Ben Ainslie Racing. Our America's Cup correspondent Todd Niall was at the Team New Zealand base. Transport Minister Simon Bridges has been caught trying to block an Official Information request for details about a proposed new 50 million dollar Auckland railway line. Kiwirail argued it was legally required to release the information, but the idea of releasing that information was making Mr Bridges 'extremely uncomfortable.' A man believed to be an Algerian student has attacked a police officer with a hammer outside Notre-Dame Cathedral in Paris. Our correspondent Peter Allen says there is still a heavy police presence. The Labour Party says the government is short changing the health sector to the tune of $2.3 billion. The party's leader Andrew Little says funding hasn't kept up with the growing population and changing demographic. The United States secretary of state Rex Tillerson used a fleeting visit to Wellington yesterday to emphasise the importance of the Asia Pacific region and denying the US is stepping back from involvement here. Foreign affairs minister Gerry Brownlee says the US pulling out of the TPP doesn't prove anything. The immediate aftermath of the devastating 2011 Christchurch earthquake and its ongoing impact on residents' mental health is being described as a recovery of two halves. The latest wellbeing survey from the Canterbury District Health Board shows that one in five people, predominantly those living in the eastern suburbs, say they experience stress most or all of the time. Nicky Wagner, the Minister supporting Greater Christchurch Regeneration, says the city has a good quality of life when compared to the rest of the country, despite a new survey showing one in five people say they experience stress most or all of the time. Ms Wagner, says 82 per cent have a good or very good quality of life in Christchurch, which compares with 81 percent nationwide. She says the east side of the city is very low lying and suffered the most damage and work is still being down in that area.
