Abstract: Critical Infrastructures (CI) such as electricity, water, fuel, telecommunication and road networks are a crucial factor for secure and reliable operation of a society. In a normal situation, most of the businesses operate on an individual infrastructure. However, after major natural disasters such as earthquakes, the conflicts and complex interdependencies among the different infrastructures can cause significant disturbances because a failure can propagate from one infrastructure to another. This paper discusses the development of an integrated simulation framework that models interdependencies between electricity and road infrastructure networks of Wellington region. The framework uses a damage map of electricity network components and integrates them with road access time to the damaged components for determining electricity outage time of a region. The results can be used for recovery planning, identification of vulnerabilities, and adding or discarding redundancies in an infrastructure network.

Abstract: Taiwan is located in the collision zones between two continental plates collide. From the perspective of plate tectonics, the paleo-tectonic environment of the Taiwan and its surrounding areas are rather complex and active due to the tectonic compression of the Eurasian Plate and Philippine Sea Plate. This has resulted in frequent earthquakes in Taiwan. In addition, the tropical and subtropical climate drives not only weathering and erosion of surface rocks, but also typhoon or monsoon triggered torrential and heavy rains in summer and autumn. For downstream land subsidence areas with poor discharge capacity, it is therefore often to have serious floods and resulted in large-scale disasters that endanger citizens' lives and property. Affected by climate change, high urban density and overexploitation of land resources, Taiwan has a substantial increase in natural disasters over the last couple of years. As the country is confronted by unfavorable environment and climate conditions, how disaster alerts and information are accurately and timely released has become an important topic for facilitating the evacuation of citizens and dispatch of disaster relief personnel. This study has combined the mobile communications technology to enable our government to, with the Cell Broadcast Service (CBS), instantly send messages to all 4G and 3G (WCDMA) mobile users within the coverage of designated base stations and without being affected by the network congestion through independent channels. This will help timely notify citizens to evacuate and reduce casualties.

Abstract: A set of publications from the online, English-language, Emergency Management (EM) doctrine has been surveyed to identify common topics in Command & Control (C2) at the tactical and operational levels. Jackson's (2013) ontological and epistemological review of the evolution of military doctrine serves as the analytic lens, enabling a link to be made to resilience and agility. The topics identified were mapped to scientific disciplines in C2. The results could be used to draw up a recommended table of contents for comprehensive EM doctrine, to guide the development of curricula for training emergency managers, and to define the user requirements for supporting information systems. In further research, the results should be compared to a similar, ongoing survey of military C2 doctrine.

Abstract: The contemporary world is characterized by several large-scale hazards to human societies and the environments we live in, including the impacts of climate change. This paper outlines theories concerning cognitive psychology and complexity dynamics that help explain the challenges of responding to these hazards and the complex systems which create them. These theories are illustrated with a baseball metaphor, to highlight the need for decision-making strategies which do not rely on comprehensive information where comprehensive information is not available. The importance of tools which can support more efficient uses of limited information is also outlined, as is the way that these tools help combine the computational resources and acquired experience of several minds. Existing research has been used to investigate many of the concepts outlined. However, further research is required to coalesce cognitive theories with complexity theories and the analysis of group-level interactions, towards improving important disaster management decisions.

Abstract: New Plymouth city's water supply infrastructure suffered major damage as Ex-Tropical Cyclone Gita passed over New Zealand on 20 February 2018. By 1950 hours a State of Local Emergency had been declared due to the disruption of the drinking water supply in New Plymouth and power supply across the region. This report focuses on the feedback received by the Taranaki CDEM Group Public Information Management team following activation of the Emergency Mobile Alert (EMA) system on the evening of Wednesday 21 February 2018, to warn people in New Plymouth District that tap water must be boiled. The report gives a practitioner's insight into making the decision to send one of New Zealand's first EMAs and the subsequent handset issues experienced by members of the public with this new system, including various misunderstandings about how the EMA system works.

Abstract: Disasters, when they strike hard, may cause the disruption of many vital services. 'Telecommunications' is being considered one of the vital lifeline services as many disaster relief operations rely on it. Effective communication is dependent on a telecommunication network infrastructure that is working properly. Unfortunately, the infrastructure may be damaged during a disaster causing no-coverage and/or congested network traffic in the disaster-affected areas. In this paper we propose a conceptual framework for building a resilient communication system that not only considers the communications infrastructure but also other driving factors which are necessary for its success. The proposed framework is based on five key pillars, namely: robustness, redundancy, adaptability, agility, and readiness to build capability for developing a resilient communication system. The findings reported in this paper provide some insights into resilient communications that may help network researchers/engineers to contribute further towards developing a robust and resilient communication system capable of coping with disasters.

Abstract: We developed a web application for location recording and rescue request using Twitter (T-Pl@ce). This application helps supported users (e.g., older adults, persons with disabilities, and children) who require support to share their location coordinates via Twitter. Supporting users (e.g., families, relatives, or neighbors) of the supported user can then check the location coordinates of the supported user when required. When the supported user needs to be rescued, he/she can post a rescue request on Twitter by pressing the “Rescue request” button on the application. In this study, we introduce the e-mail notification function to reliably notify a rescue request to the system administrator. In addition, to track the location of the supported user, we introduce a location tracking function. Then, the administrator, the emergency assistance employees (e.g., rescue experts or social workers), or the supporting user can refer to the request and the location tracking page and execute the support and rescue activities.

Abstract: In 2015 Wellington joined the 100 Resilient Cities Organization and began a new chapter in its resilience journey. This journey has seen a strategic focus on the use of data to enable better emergency response and to integrate and inform decision making at all levels. The strategic focus in the resilience strategy of integrating data into governance, adaptation, recovery and community engagement has helped Wellington manage the effects of the 2016 Kaikoura Earthquake, lead engagement on sea level rise and integrate resilience building measures into the city's built environment and communities. This strategic intent has driven the renewal of a city data capability to provision the Risk Reduction, Readiness, Response and Recovery of the city.

(pp. 534–543). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: Nepal is one of the most popular travel destinations because of its natural beauty and Himalayas. Tourism industry contributes significantly to the nation's GDP. However, the 2015 earthquake has created great havoc causing loss of more than 9,000 lives, damaging many buildings including World heritage sites and trekking trails. Despite a substantial amount of foreign aid, overall recovery programs have not been effective. This empirical study focuses on the use of ICT tools for the recovery works in the tourism industry and uses mixed methods engaging tourism associations and organisations. Four 'areas of concerns' regarding ICT use, are identified by using the qualitative analysis and validated through a survey of 198 tourism organisations. The findings show that the earthquake has significantly impacted the industry and the government has not adequately used ICTs in the recovery activities. This study strongly advocates using ICT tools for the post-disaster tourism resilience.

Abstract: Natural and manmade disasters pose a myriad of challenges, which are more severe for individuals with disabilities. Ordinarily to perform daily activities, the disabled get support from assistive technological devices and services; these are commonly disrupted during and after disasters. A proposed solution to support those with visual impairment is a cost-effective wearable 'Smart Cap'. The Smart Cap provides narratives about the surrounding environment while establishing communication between the user (the visually impaired) and a rich online reservoir of knowledge base system capable of vocalising narratives. As a proof-of-concept, this study is implemented using Raspberry Pi, the Amazon Web Services and a P-Cap fitted with a camera. The aim of this research work is to provide an assistive technology to help the visually impaired navigate their way out of any potentially disastrous situation like other citizens would. The proposed system and its usage in disaster situations is an innovative, cost-effective solution specifically addressing the needs of visually impaired persons.

Abstract: Japanese society is aging rapidly, so an increasing number of households currently consists of only elderly single people or couples. We propose a system that uses LINE (a mobile communication application) for sending notices containing information from local governments to elderly or physically disabled people, as well as for efficient monitoring by local governments and social workers of the health conditions and statuses of such people. Our system can be used by anyone who has a smartphone with LINE installed. We have also conducted an operational test of a prototype of our system.

Abstract: Smart Service Queensland (SSQ) is the 'front door' to the Queensland State Government in Australia, providing services and information for citizens and businesses. Services are delivered through online channels, call centres and face-to-face service centres. Rostering to adequately staff the call centres during business as usual demand is well supported using existing workforce planning tools and content management systems alongside real-time telephonic monitoring. However, during times of large scale emergency events, such as floods and tropical cyclones, effective workforce planning heavily relies upon experienced SSQ personnel constantly monitoring and updating call centre staffing levels leading up to and during the disaster event to ensure customer demands are met. Achieving the right balance of call centre servicing without over provisioning is a challenging task. We present a prototype analytics tool that supports the SSQ Forecast Analyst responsible for workforce planning during disaster events and provides initial results of modelling caller behavior during two recent tropical cyclones. The tool provides a single point of reference to a wide collection of relevant datasets, including population demographics and details of the natural and built environment, data feeds describing the emergency event under investigation, relevant social media posts and call centre operations metrics. The tool is an early proof of concept demonstrator highlighting the utility of data integration, web mapping, real-time event monitoring, and predictive modelling.

(pp. 504–515). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: In disasters, several national, international, and non-governmental organisations such as police, health, ambulance, fire and civil defence services are usually involved in the response process. Therefore, it is crucial that responding agencies communicate effectively to avoid fragmentation and duplication in services, to harmonise separate activities, and to clarify roles and responsibilities. Central to communication is information exchange. Effective information exchange enhances not only the appropriateness and success of disaster response, it also ensures timeliness. However, cross-agency communication is extremely challenging especially at times when there are high stress levels, incomplete data, and minimum time to make critical decisions. This paper attempts to specify a 'best-practice' model for cross-agency communication built around the specific information requirements of disaster management and disaster medicine agencies, with the aim of improving the overall quality of healthcare services provided to disaster victims.

Abstract: Following two Major Incident Reviews and a request from WA's governing emergency management body, DFES WA acknowledged that their incident management processes were not supporting seamless communication and collaboration. After identifying their unique needs, DFES implemented two web-enabled platforms: WebEOC, a Crisis Information Management System and Whispir, a multichannel notifications solution. Both systems offer DFES and, in turn, WA communities a level of transparency, collaboration and accuracy not previously available. Recently, six of WA's key government agencies have connected their WebEOC platforms via a single information hub. Through this, they can share and disseminate crucial information within a common operating picture, have complete situational awareness, and rapidly and intelligently prepare for and respond to incidents. WA is the first Australian state to have such a platform implemented and, through these efforts, its agencies are ensuring increased efficiency, collaboration and resiliency for themselves and the wider WA population.

Abstract: Given the rising trend of natural and technological disasters in recent years, the demands for emergency responders are on the rise. One main challenge is how to cost-effectively train emergency responders. In this research, we aim to explore of the usage of Virtual Reality (VR) technology in an emergency healthcare training setting. We start with the following two research questions: (1) how to implement the VR technology to be used in the emergency healthcare training; and (2) how to evaluate the effectiveness of our implementation. To address the question (1), we construct emergency healthcare workflows from reference sources, convert them into process diagrams, and develop a VR software that allows users to carry out the processes in a virtual environment. To address question (2), we design an experiment that collect participants's personal data (features such as Age, Technical background etc.) and the performance data (such as timespan, avatar moving distance, etc.) generated during the training sessions. Ten participants were recruited and each performed three training sessions. We evaluate the data collected and have the following three conclusions: (a) despite the different personal features, the participants, after repeated trainings, can improve their performance with reduced timespan and moving distance; and (b) the technical background plays the most significant role among other features in affecting timespan in our VR-based training.

(pp. 213–222). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: ABSTRACT Victorian temperate forests, characterized by variable wildfire response traits, such an analysis is missing hindering fire impact estimation over large areas on operational basis. To close this gap, we have evaluated 10 remotely sensed indices across eight areas affected by wildfires in 1998, 2006, 2007, and 2009 which comprise 13 forest types. The analysis was carried out at forest type level and as a function of the regeneration strategies (seeders, basal and epicormic reporters) and structure (tree height and canopy cover) with the six forest groups. Index performance was evaluated by (i) examining index response across four fire severity levels, (ii) the separability index, and (iii) the optimality values analysis. A ranking scoring system was used to compare the index performance to distinguish among severity classes. Initial results demonstrated that there hasn't been a consistency of the best indices capacity but there a consistently worse index among forest groups.

(pp. 110–122). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: Most countries are now establishing multi-stakeholder, multi-institutional networks and partnerships to respond to flood disasters. The paucity of research directed towards knowledge transfer in networks keeps some important research questions unanswered. These include (1) how the knowledge of a certain disaster management stakeholder (or a group) is transferred to other stakeholders during the disaster response, and (2) what are the barriers and enablers of knowledge transfer in multi-stakeholder environments. This article analyses knowledge transfer practices employed by a selected local government agency and a community group in Sri Lanka and reflects on the practices with the help of Hedlund's Knowledge Management Model (1994). The grounded theory analysis was used in this study to present the enablers and barriers of knowledge transfer in this context and the findings have a great potential to be used in future research towards developing knowledge management models specific to disaster response.

End-user perceptions of natural hazard risk modeling across policy-making, land-use planning, and emergency management within New Zealand local government.

(pp. 550–560). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: While the development of risk modelling has focussed on improving model accuracy and modeller expertise, less consideration has been given to understanding how risk models are perceived and used by the end-user. In this think-piece, we explore how risk modelling is perceived and used by three different end-user functions for natural hazard risk management in New Zealand local government: policy-making, land-use planning, and emergency management. We find that risk modelling is: valued and used by policy-makers; less valued within land-use planning and not as widely used; and valued within emergency planning but not as widely used. We offer our thoughts as to why this is the case with reference to focus groups and qualitative interviews held with local government natural hazard risk end-users across the Wellington, Hawke's Bay and Gisborne regions of New Zealand. We conclude with recommendations for how risk modelling can be further developed to increase community resilience.

(pp. 416–427). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: Official policies, socioeconomic and demographic factors influence how individuals cope with, and respond to natural disasters. Understanding the impact of these factors in social media crisis communications studies is difficult. This paper focuses on convergence behaviour during social media crisis communication in an environment where the access to commercial social media platforms is highly restricted. This study is designed as a case which analyses 41,745 Tweets communicated during an earthquake event and for the two weeks after. This research aims to understand how different communities use social media services for communication during extreme events. The content of the Tweets shows users' attitudes toward government policies as well as the social difficulties of ethnic groups reflecting on the use of social media in crises communication. The results indicate a “political effect” on this online crisis communication. This behaviour was not expected and has been underreported in the current body of knowledge.

Abstract: Emergency management organisations across the world routinely use social media to reach out populations for preparedness and response to extreme weather events. In this paper we present a preliminary analysis of social media strategies towards vulnerable populations in the State of Victoria (Australia). Using the notion of vulnerability in an emergency management context (e.g. older persons, socially/geographically isolated persons, people with disabilities, refugee/recent migrant communities) we explore whether and how organisations address vulnerable groups with targeted messages. Our initial findings suggest that organisations do not tend to interact directly with these groups. Rather, reliance on 'information brokers' (intermediary organisations and individuals with an expected duty of care) seems to be a preferred strategy.

(pp. 326–338). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: Multiple disaster mobile applications (apps) already exist for public use; however, availability does not automatically translate to continued usage. Limited research has explored whether disaster apps are usable and whether the apps' usability affects users' intent for continued use. The paper presents a work-in-progress study that aims to test a usability-continuance intention model for the specific context of disaster apps. The study theorises seven usability factors that influence continued intention to use. An online usability survey was used to gather user experience data on disaster apps. Initial findings, through structural equational modelling, showed that five of the seven usability factors have a significant relationship to continuance intention. Although the relationships have different weights and directions, key influencers to users' intent to continue usage are app utility, app dependability, interface output, interface input, and interface graphics. The next step of the study will investigate the mediating effects of the factors and the moderating effects of users' experience and technological comfort.

(pp. 200–212). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: Interferometric synthetic aperture radar (InSAR) has been widely used for mapping terrain and monitoring ground deformation. For example, the advanced time series InSAR (TS-InSAR) technique has been increasingly used to measure mm-level urban deformation. Subsidence from underground tunnel excavation has been known for more than a decade in Guangzhou and Foshan in Southern China, but past studies have only monitored the subsidence patterns as far as 2011 using InSAR. In this study, the deformation occurring during the most recent time-period between 2011 and 2017 has been measured using COSMO-SkyMed (CSK). We found that significant surface displacement rates occurred in the study area varying from -35 mm/year to 10 mm/year. A comparison between temporal and spatial patterns of deformations from our TS-InSAR measurements and different land use types in Guangzhou shows that there is no clear relationship between them. A detailed analysis on the sinkhole collapsed in early 2018 has been conducted, suggesting that surface loading may be a controlling factor of the subsidence, especially along the road and highway. Continuous monitoring of the deforming areas is important in order to minimise the risk of land subsidence and prevention of disasters.

(pp. 439–449). Albany, Auckland, New Zealand: Massey Univeristy.
Abstract: Citizens and Emergency Managers need to be able to distinguish “fake” (untrue) news posts from real news posts on social media during disasters. This paper is based on an online survey conducted in 2018 that produced 341 responses from invitations distributed via email and through Facebook. It explores to what extent and how citizens generally assess whether postings are “true” or “fake,” and describes indicators of the trustworthiness of content that users would like. The mean response on a semantic differential scale measuring how frequently users attempt to verify the news trustworthiness (a scale from 1-never to 5-always) was 3.37. The most frequent message characteristics citizens' use are grammar and the trustworthiness of the sender. Most respondents would find an indicator of trustworthiness helpful, with the most popular choice being a colored graphic. Limitations and implications for assessments of trustworthiness during disasters are discussed.

Abstract: In this paper, utilising the core Project AF8 Alpine Fault earthquake scenario, we detail hazard exposure, impacts, and recovery of interdependent critical infrastructure networks across the energy, transportation, water & waste, and telecommunications sectors across the South Island of New Zealand. Asset failures are simulated across each individual network, based on shaking intensities, exposure to co-seismic hazards and estimated component fragilities, which have been further refined and validated through expert elicitation. Network disruptions are then propagated across an interdependent network framework to quantify and delineate the spatial reach of both direct and indirect failures. By incorporating recovery strategies, temporal changes in service levels are quantified to offer insights into expected interdependent network performance and the possible disconnection of communities from the nationally connected networks, otherwise not apparent when studying each infrastructure in isolation.

Abstract: The magnitude 6.3 Christchurch earthquake struck the city at 12:51pm on Tuesday, 22 February 2011. Christchurch Hospital sustained damage following the earthquake which severely strained the hospital's ability to function at regular capacity. Three acute medical wards had to be evacuated immediately after the earthquake and relocated to an older person's health hospital. This insight paper makes a unique contribution to the field of resilience by demonstrating the practical application and positive impact of the Resilience Engineering and shared leadership to team performance in one of the relocated acute medical wards during the initial two years following the earthquake. This paper which is still work in progress was developed from the experiences and reflections of the author, who was a charge nurse manager of one of the relocated wards and led a nursing team during the earthquake, evacuation, and relocation. Taking RE model as a framework for creating resilience in complex and unexpected environment proved to be a very positive experience which created multiple learnings and prompted the team to develop sustained resilience at personal, interpersonal and professional levels. Working on this insight paper prompted the author to explore possible application of Resilient Engineering in health care environment, taking it as foundation principle of developing resilient health care in the context of complex adaptive systems. This transformed onto Ph.D. research which will be submitted to the conference colloquium.
