A large pile of liquefaction silt at a dump on Breezes Road. The photographer comments, "Breezes Road and Anzac Drive have recently opened but are now home to a brand new range of hills thanks to mountains of silt that have been collected by the hard working construction guys that have done a sterling job on the road there".

Liquefaction surrounds a car on Hendon Street in St Albans, near the corner with Hills Road. In the background, 'keep clear' tape cordons off the front of a property.
Large piles of liquefaction silt at a dump on Breezes Road. One of the piles is covered with black plastic and weighted down with tyres. Trucks and diggers are adding more silt to the piles. The photographer comments, "Breezes Road and Anzac Drive have recently opened but are now home to a brand new range of hills thanks to mountains of silt that have been collected by the hard working construction guys that have done a sterling job on the road there".

Numerous rockfalls released during the 2010–2011 Canterbury earthquake sequence affected vital road sections for local commuters. We quantified rockfall fatality risk on two main routes by adapting a risk approach for roads originally developed for snow avalanche risk. We present results of the collective and individual fatality risks for traffic flow and waiting traffic. Waiting traffic scenarios particularly address the critical spatial-temporal dynamics of risk, which should be acknowledged in operational risk management. Comparing our results with other risks commonly experienced in New Zealand indicates that local rockfall risk is close to tolerability thresholds and likely exceeds acceptable risk.
A photograph of staff from Abseil Access in the car park outside their office on Quakers Quay in Woolston. The staff are standing next to a trailer full of rocks which they have gathered from the Port Hills. The rocks will be painted and used to define the boundaries of Rock on Eastside, an outdoor lounge and art space on the corner of Linwood Avenue and Aldwins Road.
A view down Manchester Street, looking south. The road is noticably buckled, and rubble from damaged buildings can be seen beyond the cordon fence. The photographer comments, "Today I ... went for a walk along the cordon to the north of Christchurch CBD which runs about one street back from Bealey Avenue. The soldiers manning the cordon seemed happy for me to take photos but I couldn't see much of the city from the barrier ... what you can see shows there's obviously a lot of damage. The roads are swollen and raised in many place. The once flat CBD will now feature plenty of hills as well as natural traffic calming features".
A photograph of Anderson and Hill Sports Power on the corner of St Asaph and Colombo Streets. Wire fences have been placed across the street as a cordon. In the background, rubble from earthquake-damaged buildings and crushed cars line the left side of the road. There is also foliage from a fallen tree.
The greater Wellington region, New Zealand, is highly vulnerable to large earthquakes. While attention has been paid to the consequences of earthquake damage to road, electricity and water supply networks, the consequences of wastewater network damage for public health, environmental health and habitability of homes remain largely unknown for Wellington City. The Canterbury and Kaikōura earthquakes have highlighted the vulnerability of sewerage systems to disruption during a disaster. Management of human waste is one of the critical components of disaster planning to reduce faecal-oral transmission of disease and exposure to disease-bearing vectors. In Canterbury and Kaikōura, emergency sanitation involved a combination of Port-a-loos, chemical toilets and backyard long-drops. While many lessons may be learned from experiences in Canterbury earthquakes, it is important to note that isolation is likely to be a much greater factor for Wellington households, compared to Christchurch, due to the potential for widespread landslides in hill suburbs affecting road access. This in turn implies that human waste may have to be managed onsite, as options such as chemical toilets and Port-a-loos rely completely on road access for delivering chemicals and collecting waste. While some progress has been made on options such as emergency composting toilets, significant knowledge gaps remain on how to safely manage waste onsite. In order to bridge these gaps, laboratory tests will be conducted through the second half of 2019 to assess the pathogen die-off rates in the composting toilet system with variables being the type of carbon bulking material and the addition of a Bokashi composting activator.
