Building a Conceptualisation of Citizen-led Low-cost Early Warning Systems


November 2021

 

Chanthujan is an electronics and telecommunication engineering graduate from the University of Moratuwa in Sri Lanka. He has a strong interest in the fields of the Internet of Things (IoT), machine learning and artificial intelligence.

Following the completion of his bachelor’s degree he joined Synopsys Lanka Pvt. Ltd. as an Application Engineer in 2018, and he currently serves as a Senior Application Engineer. After gaining some experience in the industry, Chanthujan began looking for opportunities where he could undertake research to solve real-life challenges while broadening his skills, knowledge and experiences.

 

Chanthujan began his PhD in Emergency Management at Massey University’s Joint Centre for Disaster Research in 2020. Chanthujan’s research is titled ‘Smart Cities, Building a Conceptualisation of Citizen-led Low-cost Early Warning Systems’. Currently, New Zealand’s primary earthquake warning generator is limited in that it can only disseminate post-earthquake information through the GeoNet website and mobile app. This means that there is no official earthquake early warning system available to give advanced warning to the New Zealand public.

Chanthujan’s research will concentrate on developing citizen-led, self-aligning and self-healing IoT-embedded systems that foster low-cost earthquake early warning applications in New Zealand. In this work, he will be applying machine learning techniques to provide advanced warnings of earthquakes accurately, while ensuring that there are no bogus warnings issued.

Chanthujan is working within the Smart Resilient Cities Workstream of the Urban programme and is supervised by Dr Raj Prasanna and Dr Max Stephens.

Modelling the social and economic impacts of a volcanic eruption in Auckland

 


By Robert Cardwell

June 2021

A research team led by University of Auckland PhD candidate and Market Economics researcher Robert Cardwell recently published new research on the simulation of economic and urban development recovery pathways following the eruption of a new volcano in the Auckland region.

The research, published in the Journal of Volcanology and Geothermal Research, demonstrates the capability to simulate not only the direct physical impacts associated with infrastructure and land use destruction and disruption, but also population and business evacuation and relocation. The team also modelled the socio-economic and land use planning implications associated with recovery and also the longer-term growth-related pressures on city development.

Figure 1 shows the impact on value added (the counterpart to Gross National Product at the regional level) of the volcanic eruption scenario over a 20 year period following the eruption compared to a baseline scenario where the eruption did not occur.

 

Figure 1: Eruption and Baseline integrated scenario total value added for industrial and commercial sectors

Figure 2 depicts the difference in development of residential and industrial land use that has occurred by September 2040 in the volcanic eruption scenario compared to the baseline scenario under a ‘Fast Recovery’ scenario.

 

Figure 2: Change in residential and industrial land use between 1st October 2019 and 30th September 2040 in the ‘Fast Recovery’ scenario

Figure 3 depicts the difference between two scenarios at September 2040 where in one scenario the land physically impacted has been remediated within a timeframe of 5 years, and another in which the remediation has taken 10 years.

 

Figure 3: Land use in ‘Fast Recovery’ scenario as at 30th September 2040 vs ‘Slow Recovery’ scenario as at 30th September 2040

The differences between the ‘Fast Recovery’ and ‘Slow Recovery’ scenarios demonstrate how taking longer to remediate the area directly impacted by the volcanic eruption can result in more urban development on the urban-rural boundaries than might have otherwise occurred.

As far as the authors are aware, this research is the first instance of simulation of land use and economic changes over time after a natural hazard event has occurred. The developments demonstrated in this research will enable planning authorities to assess trade-offs with competing objectives in mitigation and redevelopment strategies to respond to volcanic eruptions and other natural hazard events.

The research was co-authored by Robert’s supervisors Assoc Prof Liam Wotherspoon (University of Auckland) and Dr Garry McDonald (Market Economics), with support from Prof Jan Lindsay (also University of Auckland). Funding was provided by the Resilience Challenge Economics and Urban research programmes with support from DEVORA (Determining Volcanic Risk in Auckland).

Post-disaster recovery from a high-impact weather event in Auckland

 

 

 

A bit about me

Anna in the hills of St. Andrew, Jamaica 2019

I am currently a PhD candidate in Disaster Management at Massey University’s School of Construction and the Built Environment.

I am an outgoing nature lover, who loves to read religious books and have a great interest in travelling. I was born in St. Andrew, Jamaica, and was raised within a humble inner-city community in Kencot, Kingston, Jamaica.

I studied a Bachelor of Arts in Geography at the University of the West Indies, Mona Campus in Jamaica and further did post-graduate studies at the University of Auckland, New Zealand, where I successfully completed a Masters of Disaster Management with first-class honours. I believe that women have a pivotal role to play in this sector and so in addition to creating tangible technical outputs for national and regional development, I also mentored young female interns in the field of disaster management, geospatial technologies, and development planning.

My interest in cartography and spatial analysis led me to play a key role in the development of the Negril Risk Atlas in Jamaica under an Enhancing Coastal Resilience Project, currently being used to assist planners when making development decisions in the region. In October 2017, I led a team to successfully execute a national GIS conference which hosted over 500 people.

My favorite phrase is “Never Say I Can’t” because all things are possible with proper planning, great team-work, communication, and great determination.

I love people! And I would like to think that my passion for people and seeing the vulnerable bounce back from increased hardships faced as a result of disasters has led me to this project.

Receiving a PhD scholarship from the Resilience to Nature’s Challenges Urban programme has allowed me to start the journey to becoming a useful expert with skills in resilience and disaster management that will be beneficial to humanity.

My project

My PhD is about post-disaster recovery from high-impact weather events in Auckland. Let’s face it, disasters have no boundaries; they can affect us all at any time in any spatial location. Auckland’s geographic location and unique physical characteristics make the region susceptible to multi-hazards and high weather-related disaster events induced by climate change. This, coupled with the projected population increase in Auckland will proliferate the risk of disasters which may potentially lead to loss of life, destruction of infrastructure, and communities.

Additionally, with the likely threat of climate change projections for New Zealand, by the end of the century, the country is likely to experience higher temperatures, rising seas levels, more frequent extreme weather events, and a change in rainfall patterns.

My research aims to study three or more of the most exposed communities in Auckland to high-impact weather events using existing vulnerability models to ascertain people’s exposure and their vulnerability to high weather events. Secondly, to assess each community’s recovery timeframes, and key factors that make them resilient and recover quickly from disasters. I will also be doing a comparative analysis scenario study of a ‘high impact’ versus ‘low impact’ recovery of coastal communities, with a focus on what makes them resilient, and what needs to be done to make them even more resilient.

 

Next steps

Undertaking this PhD project will include developing a strategic futuristic recovery and resilience plan. It is important to understand that to strategically plan for a resilient nation, as one of the key goals of the Resilience Challenge, it is critical to incorporate resilience as a priority in community planning. This would facilitate the creation of ground-rules for agencies to implement in their strategic recovery planning process. My interest is enhancing Auckland’s capability to quickly recover from disasters, by collaboration among sectors; managing risks, effective response to and recovery from emergencies, and fostering community resilience. With this project underway, I believe it will add value to the resilience and development planning sector.

Smart and Resilient Cities

 

 

 

A bit about me 

 

I was born and raised in Damghan city, which was the capital of Iran during the Parthian Empire. Damghan has many ancient monuments and is a tourist attraction. The city is also famous for its trade in pistachios and ‘kaghazi’ almonds with very thin shells.

At high school I focused on the mathematics and physics stream. Growing up with my profound interest in engineering science, I pursued undergraduate studies in Civil Engineering, and as a fresh graduate, I joined a construction company as a site engineer in Iran. Since I was looking forward to broadening my knowledge and experiences, I decided to pursue my masters studies abroad.

I graduated in Master of Structural Engineering and Construction program from University Putra Malaysia.  Upon completion of my masters, I started working as a research assistant and a lecturer in Malaysia. I spent four years as a research assistant at the University of Malaya with eight patents and seven publications, and a further four years at the Limkokwing University of Creative Technology as a Faculty coordinator and lecturer; teaching undergraduate students, leading the faculty team and providing the full range of student services.

I decided to push myself forward to new experiences and challenges by continuing my studies at PhD level. I started my research at the University of Auckland under the supervision of Professor Suzanne Wilkinson in the broad area of Smart and Resilient Cities, and how these two notions can be compiled. I believe that my interdisciplinary and international background, along with Suzanne’s supervision, will allow me to complete this large-scale project effectively.

 

My project

 

The research aims to propose novel frameworks that could establish and further the idea that resilience could support urban ‘smartness,’ a term that is widely argued as not being easily measured nor quantifiably assessed. While the smart city concept relies on the roll-out of technology to improve urban standards, the idea of resilience prepares the city against any catastrophic events allowing it to absorb, adapt and transform external pressures and improve public safety.

Smart city and urban resilience are both contemporary concepts that evolved to further sustain urban livelihoods, by offering strategic solutions to issues arising from population growth and human activities. Smart cities use technological means to improve city services and enhance the urban system, resulting in the city’s resiliency, which simultaneously determines urban sustainability.

Next steps

 

I am in the first year of my PhD studies. Based on discussions with my supervisor Suzanne, I plan to publish four journal papers in the first year of study by using the proposed frameworks and hypothetical cases. Later on, a comprehensive indicator bank for Smart and Resilient Cities will be proposed and the novel frameworks will be examined in real cities like Auckland, Christchurch, Wellington, Sydney, Melbourne, Toronto and Vancouver.

Q & A with Prof Jan Lindsay

 


 

Q. Tēnā koe Jan. First of all, congratulations on your recent promotion to Professor!

Tēnā koe. Thank you. To be honest it still feels quite surreal! I think it is important to acknowledge that an academic career is built on collaborations – with mentors, students, fellow researchers and teachers, funders…and I wouldn’t have achieved promotion to Professor without the great mahi of all my collaborators. I hope they all realise how much I appreciate them!

Q. How did you get into volcanology? Have you always been fascinated with volcanoes?

Although I grew up in Rotorua surrounded by volcanoes it was only when I hit university that I developed an interest in Earth Science. Ironically, I didn’t do much science at high school and went to university to study languages and linguistics (English and German) with the aim of becoming a teacher! I took two Geology papers in my first year for fun, to fill a gap in my timetable because the description in the prospectus sounded interesting. It didn’t take long before I was hooked – and over the next 3 years converted from a BA to a BSc, and I guess the rest is history. I became specifically interested in volcanoes when I did my MSc on Hauturu – Little Barrier Island volcano in Auckland’s Hauraki Gulf.

Q. I understand you’re the first woman Professor of Volcanology in New Zealand. Do you have thoughts on how can we inspire more girls and women to take up earth sciences, and support them into leadership roles?

There are about 6 or 7 people in Aotearoa New Zealand that would probably identify as Professors of Volcanology, and yes I am the only woman. In Earth Science as a whole it is not much better – I believe I am just one of 2 or 3 active female Earth Science Professors. We actually have a good number of women studying Earth Science and going on to do postgraduate study, but there are so few positions available after students finish their PhD that they often hit a wall and change career path or head overseas. More support for postdoctoral fellowships would make a big difference.     

Q. You’re co-leading the Urban theme for Phase 2 of the Challenge. What drew you to working on a National Science Challenge?

I was only peripherally involved in the first phase of the Challenge, and was really happy when the opportunity came up to join Phase 2 as theme leader for Urban. What drew me to it was the desire to be part of a great team with a great Kaupapa – the Theme leaders across the challenge are all exceptional researchers who are committed to a resilient future for Aotearoa, to nurturing the next generation of researchers, and to enhancing Mātauranga Māori, all things I fully support.

Q. What parts of the Urban research programme are you most excited about?

I am really excited about a new collaboration with law Professor John Hopkins at the University of Canterbury looking at governance around disaster response in the event of an Auckland Volcanic Field eruption. This particular project is co-funded by DEVORA (see below) and is an exciting addition to current research on Auckland’s volcanoes. The premise is if we can front-foot governance structures, laws and plans to be optimised for resilience and recovery we can reduce the shock and impact of a future event.

  Q. You also co-lead the multi-agency, interdisiplinary research programme DEVORA (Determining Volcanic Risk in Auckland). Can you tell us a bit about that?

DEVORA is a multi-agency research programme co-led by myself and Graham Leonard (GNS Science) and funded by EQC and Auckland Council. Our research ranges from fundamental geological, petrological and geophysical studies on the nature of the Auckland Volcanic Field (AVF) to assessment of impacts and risk of a future eruption. The programme has been active for over 10 years and we have made some really important advances in understanding the AVF and the enormous economic, social and physical impacts that an eruption would have. A really important outcome is our whakawhanaungatanga, especially the relationship building between our researchers and Auckland Emergency Management. We also have an active steering committee of representatives from EQC and Auckland Council who help define research priorities, and we put a lot of effort into outreach via community events such as the Auckland Heritage Festival and our Facebook page.

Q. You’ve spent a lot of time studying and working overseas – in Germany, Chile, and the Carribean. How have these experiences influenced your research interests here?

My MSc supervisor Ian Smith used to say that volcanology is the ‘adventure science’, and I have indeed been lucky in my career to have had many adventures around the world. My experience overseas in seeing how people (in general) and authorities (in particular) interact with volcanic hazard and risk information really sparked my interest in volcanic hazard and risk communication, which I now focus a lot on here. For example, I have done field work to assess volcanic hazard in several overseas volcanic regions where authorities have instructed me not to mention to anyone what I was there for. In other places I have seen school children totally embrace the idea that they live on an active volcano and soak up information about their hazard and risk. These sorts of encounters have definitely shaped my research interests back in New Zealand, where I am really interested not only in how volcanoes work but how we might communicate what they might do in the future, for example via hazard maps or eruption forecasting or decision-making tools.   

Q. What are your future aspirations?

Other than to continue to work with an amazing group of students and researchers, I would love to see an increase in participation of Māori and Pasifika researchers in the Earth Sciences and aspire to support initiatives that aim to do just that.

Disaster risk reduction and building code amendment in post-disaster reconstruction in New Zealand

 

 

 

A bit about me 

 

I was born in Owerri, the capital of Imo state which is located in the eastern part of a multi-cultural country in Africa called Nigeria. I gained a bachelor’s degree in civil engineering (B.Eng) and my first master’s degree in structural engineering (first class honours), both from the Federal University of Technology Owerri, Nigeria. My desire to know more about disasters in the built environment and how I can contribute to reducing their impact propelled me to obtain my second master’s degree in Natural Hazards and Risks in Structural Engineering (NHRE) from Bauhaus University Weimar, Germany. I also have several years of working experience as a structural engineer, site engineer and research assistant.

 

 

 
I moved to New Zealand in 2018 to pursue a PhD in Civil Engineering at The University of Auckland and to learn more about disasters. I enjoy playing football, cooking and practising my German language. My interest lies in finding solutions to hazards in the human-built environment.

 

My project

 

My PhD research focuses on the impact of rebuilding New Zealand cities with amended building code compliance documents, with emphasis on Christchurch and Kaikōura. To do this, I will identify the impacts of building code amendments on post-disaster reconstruction, and examine the process of building code amendment and its relationship to disaster risk reduction.

I am using the 2010/2011 Christchurch earthquake and 2016 Kaikōura earthquake as my case studies. The knowledge gained from these case studies will be used to check the preparedness of Auckland and Wellington, particularly in the context of the anticipated ground shaking in Wellington. The aim of this research is to provide recommendations on how to reduce the impact of earthquakes in post-disaster reconstruction and inform building code regulators on how to improve the code adaptation process through a developed framework. My supervisors are Professor Suzanne Wilkinson and Associate Professor Charles Clifton.

 

Next steps

 

My first phase of data collection started in April 2019. This involves administering questionnaires to building code regulators, building and construction industry, building consent authorities, government officials and other stakeholders. The data I obtain will then be validated with existing literature. The aim of this phase is to develop an understanding of the impact of building code compliance document amendments on post-disaster reconstruction.

The second phase of my research will involve conducting semi-structured interviews with the stakeholders. This will focus on using the gained knowledge to check the preparedness and mitigation strategies in place for Wellington.

Although the entire project is challenging, I enjoy exploring New Zealand performance building code and relating it to post-disaster reconstruction processes. I am planning to continue the research work by using knowledge, results, and developed frameworks in other cities globally.

‘Anchor projects’ as cornerstones of city-rebuilding post-disaster

 

 

 

A bit about me 

 

I’m from Sri Lanka, the island paradise of the Indian Ocean. I’m currently a second year Civil Engineering doctoral candidate at The University of Auckland. I initially completed my BA (Honours) in Economics at the University of Colombo whilst also reading for a Professional Post-Graduate qualification in Marketing. I then went to the UK where I did an MSc in Project Management and that led me to my current research in New Zealand in the area of disaster management. I’ve specialised in vastly different subject areas and I strongly believe that this sets me apart from the typical engineer. I believe knowledge in many areas is an added bonus when working in teams because knowing more gives one more control over the process.

 

 

Even though my research focuses on disaster management, there is a huge part of me that loves art, languages and creativity in any form. As a result, I learnt French and then at one point started giving lessons too!  I’m also totally into nature these days. I have fallen for the natural beauty of New Zealand and it has brought out the photographer, voyager and nature lover in me.

 

My project

 

A disaster marks a remarkable turn-around for a country, whether it is economic, social, political or a fusion of all three. Therefore, it is crucial that governments make the best decisions with regard to their post-disaster rebuilding. In the recent past, the world has witnessed cities being rebuilt through key public projects. These are also known as Anchor projects, Priority Projects, Catalyst Projects or Flagship projects. The main objective of these projects is to aid the rebuilding of cities post-disaster. Substantial investment, resources and time are dedicated to these. It is expected that these projects are pioneers in economic regeneration and are focal points in the urban plan following a disaster.

My work is mainly focused on understanding these key public projects that have been undertaken by governments in the developed world following large natural disasters. I’m using the case studies of the 2010-2011 Christchurch earthquakes and Australia’s 2009 Black Saturday Bushfires in Victoria. In Christchurch only a handful of projects out of the proposed 17 have been completed 9 years down the line (see the map of proposed Christchurch Anchor Projects below).

In Australia, although the projects were completed on time, whether they have delivered what was expected remains to be seen. Planning, decision-making, resource management and project portfolio management may have contributed to the negativity surrounding them.

 

Next steps

 

I will start my first phase of data collection in March, 2019. This will involve conducting one on one semi-structured interviews with government officials in both Victoria and Canterbury. I hope to gain an understanding of the planning process and the project management issues. The data gathered will be validated against findings from focus group discussions involving all stakeholders, including government officials, architects, contractors and the end users of these establishments. This phase will shed light on how planning and project management affect the end results of these projects. It is expected that my research will deepen the understanding of the role of anchor projects in post-disaster rebuilding efforts of the government. I will also produce best practice decision-making guidelines for future reference of the respective governments.

I am excited about the potential of this research as one of the few studies focusing on  the role of public projects following a natural disaster. I also hope that the decision-making guidelines I produce will help governments make better decisions around post-disaster planning and government spending.
