From lessons identified to lessons learnt
Purpose This study examines how search and rescue (SAR) organisations operate in practice and identifies recurring patterns in SAR exercise evaluations across Aotearoa New Zealand. Design/methodology/approach A qualitative document analysis was conducted on 98 Category 1 search and rescue exercise (SAREx) evaluation reports produced between 2011 and 2025 across New Zealand Police districts. Analysing reports spanning fourteen years allowed the id…
Navigating scientific modelling and uncertainty
Scientific models have long been used as an important tool in assisting in decision-making in Disaster Risk Management (DRM). However, it is commonly understood that uncertainty in these models significantly influences the integration of model outputs into decision-making processes, presenting a challenge for effective uncertainty communication. This paper explores how scientists in DRM approach modelling and uncertainty. We conducted seventeen i…
Nurturing partnerships to support data access for impact forecasts and warnings
This paper presents a synthesis and theoretical integration of findings from a research project that explored the data needs and sources for implementing impact forecasts and warnings (IFW) for hydrometeorological hazards. Impact forecasts and warnings (IFW) have received global attention in recent years as they offer a novel way of improving the communication of hazards and risks. The fundamental idea behind IFWs is to enable warning services to…
Knowledge, perceptions, and behavioral responses to earthquake early warning in Aotearoa New Zealand
Introduction Aotearoa New Zealand (NZ) experiences frequent earthquakes, with a history of damaging and fatal events, but currently does not have a national, official earthquake early warning (EEW) system. Since April of 2021, Google's Android Earthquake Alert System has operated independently in NZ. While recent work has identified general public support for such a system, it is important to assess public knowledge of EEW as well as typical resp…
The public's perception of an earthquake early warning system
Identifying the Impact-Related Data Uses and Gaps for Hydrometeorological Impact Forecasts and Warnings
Impact forecasts and warnings (IFW) are key to resilience for hydrometeorological hazards. Communicating the potential social, economic, and environmental hazard impacts allows individuals and communities to adjust their plans and better prepare for the consequences of the hazard. IFW systems require additional knowledge about impacts and underlying vulnerability and exposure. Lack of data or knowledge about impacts, vulnerability, and exposure h…
Understanding the social aspects of earthquake early warning
Earthquake early warning (EEW) systems aim to warn end-users of incoming ground shaking from earthquakes that have ruptured further afield, potentially reducing risks to lives and properties. EEW is a socio-technical system involving technical and social processes. This paper contributes to advancing EEW research by conducting a literature review investigating the social science knowledge gap in EEW systems. The review of 70 manuscripts found tha…
Collaborative public service provision archetypes in healthcare emergencies
Purpose This paper examines how the properties and patterns of a collaborative “networked hierarchy” incident command system (ICS) archetype can provide incident command centres with extra capabilities to manage public service delivery during COVID-19. Design/methodology/approach The paper illustrates the case of Sri Lanka's COVID-19 administration during its “first wave” (from 15 February to 1 September 2020). Primary data were collected through…

Micro-theory on knowledge transfer to foster disaster resilience
Although recent literature suggested that knowledge generation and dissemination in social networks influence resilience, research in knowledge transfer and social capital domains have shown a low tendency to integrate into theoretical frameworks. This paper discusses the process of building a micro-theory, which explains the dynamics of knowledge transfer in social networks of disaster responders in Sri Lanka. The proposed theory suggests the as…
Usability factors influencing the continuance intention of disaster apps
Scoping the potential for earthquake early warning in Aotearoa New Zealand
Earthquake Early Warning (EEW) systems are used to detect earthquakes and provide advanced notice of strong shaking intensity, allowing people to take pre-emptive actions that benefit the health of infrastructure and the life-safety of the public. With the advancement of technical research of EEWs, there is also an increasing need to understand EEW's potential impacts on society. In this study, we investigated the perspectives of various sectors …
Enacting “accountability in collaborative governance”
Purpose The paper illustrates how accountability of collaborative governance was constituted in the context of disaster managerial work carried out by the Government, local authorities, and Maori community organisations, after the 2010–2011 Canterbury earthquakes in New Zealand. Design/methodology/approach A case study detailing the communitarian approach to disaster recovery management by a nationalised Maori earthquake response network is contr…
