A significant portion of economic loss from the Canterbury Earthquake sequence in 2010-2011 was attributed to losses to residential buildings. These accounted for approximately $12B of a total $40B economic losses (Horspool, 2016). While a significant amount of research effort has since been aimed at research in the commercial sector, little has been done to reduce the vulnerability of the residential building stock.

An audio recording of a mayoral debate hosted by Generation Zero in partnership with 350 Christchurch. The event was titled Mayoral Debate: a climate-smart Christchurch. It was held on campus at the University of Canterbury on Thursday 22 September, 2016 and was moderated by Catarina Gutierrez of the Ministry of Awesome. The debate was structured as follows: Section 1: Candidates answered set questions sent prior to the event Section 2: Candidates answered set questions they have not seen before Interval Section 3: Candidates answered written questions from the audience (climate-related questions were submitted during the interval and a selection of these were given to the moderator). The audio recording was taken through the University's Echo system.

Geospatial liquefaction models aim to predict liquefaction using data that is free and readily-available. This data includes (i) common ground-motion intensity measures; and (ii) geospatial parameters (e.g., among many, distance to rivers, distance to coast, and Vs30 estimated from topography) which are used to infer characteristics of the subsurface without in-situ testing. Since their recent inception, such models have been used to predict geohazard impacts throughout New Zealand (e.g., in conjunction with regional ground-motion simulations). While past studies have demonstrated that geospatial liquefaction-models show great promise, the resolution and accuracy of the geospatial data underlying these models is notably poor. As an example, mapped rivers and coastlines often plot hundreds of meters from their actual locations. This stems from the fact that geospatial models aim to rapidly predict liquefaction anywhere in the world and thus utilize the lowest common denominator of available geospatial data, even though higher quality data is often available (e.g., in New Zealand). Accordingly, this study investigates whether the performance of geospatial models can be improved using higher-quality input data. This analysis is performed using (i) 15,101 liquefaction case studies compiled from the 2010-2016 Canterbury Earthquakes; and (ii) geospatial data readily available in New Zealand. In particular, we utilize alternative, higher-quality data to estimate: locations of rivers and streams; location of coastline; depth to ground water; Vs30; and PGV. Most notably, a region-specific Vs30 model improves performance (Figs. 3-4), while other data variants generally have little-to-no effect, even when the “standard” and “high-quality” values differ significantly (Fig. 2). This finding is consistent with the greater sensitivity of geospatial models to Vs30, relative to any other input (Fig. 5), and has implications for modeling in locales worldwide where high quality geospatial data is available.

A video of a presentation by Dr Penelope Burns during the second plenary of the 2016 People in Disasters Conference. Burns is the Senior Lecturer in the Department of General Practice at the University of Western Sydney. The presentation is titled, "Recovery Begins in Preparedness".The abstract for this presentation reads as follows: Involvement of primary care doctors in planning is essential for optimising the health outcomes of communities during and after disasters. However, our experience in Australia has shown that primary care doctors have not been included in a substantial way. This presentation will highlight our experience in the Victorian and New South Wales bushfires and the Sydney Siege. It will stress the crucial need to involve primary care doctors in planning at national, state, and local levels, and how we are working to implement this.

he 2016 Building (Earthquake Prone Building) Amendment Act aims to improve the system for managing earthquake-prone buildings. The proposed changes to the Act were precipitated by the Canterbury earthquakes, and the need to improve the seismic safety of New Zealand’s building stock. However, the Act has significant ramifications for territorial authorities, organisations and individuals in small New Zealand towns, since assessing and repairing heritage buildings poses a major cost to districts with low populations and poor rental returns on commercial buildings.

During the 2011 M7.8 Kaikōura earthquake, ground motions recorded near the epicentre showed a significant spatial variation. The Te Mara farm (WTMC) station, the nearest to the epicentre, recorded 1g and 2.7g of horizontal and vertical peak ground accelerations (PGA), respectively. The nearby Waiu Gorge (WIGC) station recorded a horizontal PGA of 0.8g. Interestingly, however, the Culverden Airlie Farm (CULC) station that was very closely located to WIGC recorded a horizontal PGA of only 0.25g. This poster demonstrates how the local geological condition could have contributed to the spatially variable ground motions observed in the North Canterbury, based on the results of recently conducted geophysical investigations. The surficial geology of this area is dominated by alluvial gravel deposits with traces of silt. A borehole log showed that the thickness of the sediments at WTMC is over 76 metres. Interestingly, the shear wave velocity (Vs) profiles obtained from the three strong motion sites suggest unusually high shear wave velocity of the gravelly sediments. The velocity of sediments and the lack of clear peaks in the horizontal-to-vertical (H/V) spectral ratio at WTMC suggest that the large ground motion observed at this station was likely caused by the proximity of the station to the causative fault itself; the site effect was likely insignificant. Comparisons of H/V spectral ratios and Vs profiles suggest that the sediment thickness is much smaller at WIGC compared with CULC; the high PGA at WIGC was likely influenced by the high-frequency amplification caused by the response of shallow sediments.

A video of a presentation by Matthew Pratt during the Resilience and Response Stream of the 2016 People in Disasters Conference. The presentation is titled, "Investing in Connectedness: Building social capital to save lives and aid recovery".The abstract for this presentation reads as follows: Traditionally experts have developed plans to prepare communities for disasters. This presentation discusses the importance of relationship-building and social capital in building resilient communities that are both 'prepared' to respond to disaster events, and 'enabled' to lead their own recovery. As a member of the Canterbury Earthquake Recovery Authority's Community Resilience Team, I will present the work I undertook to catalyse community recovery. I will draw from case studies of initiatives that have built community connectedness, community capacity, and provided new opportunities for social cohesion and neighbourhood planning. I will compare three case studies that highlight how social capital can aid recovery. Investment in relationships is crucial to aid preparedness and recovery.
