Liquefaction hazard in the Wellington Region

GD Dellow, ND Perrin & WF Ries
The greater Wellington Region has a higher annual probability of damaging ground shaking than most of the rest of New Zealand. This means that the region is exposed to all of the effects of strong earthquake shaking including fault rupture, ground movement, liquefaction and landslides. This report deals specifically with the liquefaction hazard in the greater Wellington Region. Liquefaction is a process that leads to a soil suddenly losing much of its strength, most commonly...

Using RiskScape to inform section 32 assessments under the Resource Management Act 1991

ES Grace, NA Horspool, J Williams, S-L Lin & R Paulik
Land use planning decisions in New Zealand, including those that aim to manage levels of risk from natural hazards, are regulated by the Resource Management Act 1991 (RMA). The RMA includes a requirement to quantify costs and benefits of proposed policy options. A project has been undertaken to determine whether RiskScape, a risk modelling tool, can offer a means of quantifying costs and benefits relating to risk management options in the manner required by section...

Characterising New Zealand butter using bulk and molecular multi-isotope analyses

KM Rogers, AM Philips, AG Immers, J Cooper, M Sim & J Fitzgerald
Food fraud is now a serious problem worldwide and the various methods of disguising the origin and authenticity of lower quality products for economic gain is increasing. For some time, stable isotopes have been employed as a tool of choice to determine origin and farming methods of agricultural and animal products. The Ministry for Primary industries (MPI) commissioned GNS Science to investigate a selection of New Zealand and overseas sourced butter to understand key differences...

Uses of sea level rise information by local government: Hawke's Bay case study

Sally H. Potter, Emily S. Grace, Ben Payne & Richard H. Levy
The uses of Sea Level Rise (SLR) information at a regional level were investigated between 2015 and 2017, using the Hawkes Bay Region of New Zealand as a case study. This work was carried out as part of the wider ‘Our Rising Tide’ GNS Science Strategic Development Fund project. Workshops were held to find out what information about SLR would be useful for key stakeholders (particularly in terms of impacts), what format would be most...

Chemical compositions of selected sinter samples from the Rotorua Museum

AG Reyes
Eight sinter samples, purportedly from the Pink and White Terraces, were geochemically analysed using neutron activation analysis (NAA). The selection represents a range of colours: violet to red to yellowish red, orangish yellow, nearly white but with faint brownish tints and brownish. Seven of the samples are from the Rotorua Museum collection acquired in 2013 and one is from Mr Blair Polly. Gold and Ag show positive correlation, as do As and Sb. However high...

It identifies three main areas where social media has supported resilient forms of behaviour. The first concerns the role of social media in supporting information-seeking behaviours during crisis events. The second looks at the role of social media in empowering individual and community actors, and in providing a forum...

GWRC flood warning review phase 2 & 3

GS Leonard, RJ Woods, JS Becker & SH Potter
Providing effective flood warning services is a critical role for Greater Wellington Regional Council (GWRC). Currently, flood warning services in the Wellington Region are provided across three parts of GWRC: Flood Protection, Environment Science and Wellington Region Emergency Management Office (WREMO). The current arrangement pre-dates the establishment of WREMO. The current system has not been reviewed recently and has never had a comprehensive review on service provision or delivery. To remedy this, a review of...

New Zealand ShakeOut is a national earthquake drill that was first held on 26 September 2012 at 9:26 am. The New Zealand ShakeOut campaign was based on international ShakeOut drill activities and was organised by the Ministry of Civil Defence & Emergency Management. It focussed on educating New Zealanders about what to do in an earthquake, communicating the ‘Drop, Cover, Hold’ message, and asking people to practice the ‘Drop, Cover, Hold’ action in an official...

Ground motions in New Zealand from Kermadec earthquakes

, &
We use numerical simulations of earthquake ground shaking to test the ability of natural warning to trigger self-evacuation in communities in the north-western North Island that are at risk of tsunami generated along the Kermadec Subduction Zone in the southwest Pacific. In this region, self-evacuation defined as “Long or Strong, Get Gone” is the dominant mechanism for risk mitigation. However, we conclude that many possible earthquakes will not be felt strongly in these regions, including...

This work provides essential information for better understand what happened in the earthquake, and to inform...

Rapid remote sensing data collection

KE Jones, JM Lee, GC Archbald, S Lawson & C Asher
The acquisition of remotely sensed, high resolution, topographic data has been transformed considerably over the past decade by new technology and geospatial processing platforms. Originally developed within the computer vision industry, Structure from Motion (SfM) is a photogrammetric method for creating 3D models of a feature or topography from overlapping two-dimensional photographs taken from many locations and orientations. SfM algorithms search for unique matches of points between two images, determining internal camera geometry and camera...

Auckland electricity outage scenario

JH Kim, NJ Smith & GW McDonald
In the ERI programme we developed a Dynamic Interoperability Input-Output Model (DIIM) to assess the economic impacts of a hypothetical electricity outage scenario in the Auckland region. We apply a hypothetical electricity transmission infrastructure loss scenario, co-developed with Transpower (electricity provider) and Vector (electricity retailer), to test the impacts of a substantial electricity outage in Auckland. The probability of the scenario is highly unlikely, but plausible for the Auckland region. The scenario is fully outlined...

Predicted column heights for carbon dioxide storage in New Zealand based on membrane seal capacity

BD Field
The underground storage of carbon dioxide requires assessments of many factors but particularly of security of storage. One of the main contributors to security of storage is the membrane capacity of seal units. This report uses mercury injection capillary pressure threshold entry pressures to assess the membrane seal capacities and hence column heights of various New Zealand mudstones. Column heights are estimated at in situ conditions for the samples analysed, except that where samples were...
