    Gamification for air quality education: A systematic literature review
    (Elsevier B.V., 2025-01-09) Daemei AB; Lovreglio R; Feng Z; Paes D; Miller C
    Air quality is crucial to our health and well-being, as poor air quality can lead to serious health problems such as asthma, allergies, and other respiratory conditions. Educating people about air quality is key to improving awareness and taking action to reduce its negative effects. Gamification offers a creative and engaging way to deliver educational content by incorporating game elements into the learning experience. However, despite its potential, there has been no review of how gamification has been used for air quality education. Thus, this review aims to fill that gap by systematically examining how gamification is applied to air quality education in the built environment. We explored a range of games and applications used to educate the public on air quality. To guide our analysis, we used the Octalysis framework, which focuses on game elements that motivate and engage users. Following the PRISMA guidelines for systematic reviews, we identified 19 relevant papers published between 2009 and 2023. From these, we developed 8 research questions to guide the review process and analyzed the game elements using the Octalysis framework. Our findings show that most studies focus on residential buildings, with a key focus on raising awareness of the health impacts of air pollution and managing asthma. Notably, many of these studies target children, who are more vulnerable to air pollution. We also introduce the first taxonomy for gamification in air quality education, providing a clear structure for future game development in this area. Finally, the review highlights the need to explore other educational topics that could benefit from gamification, and how this approach could improve both indoor and urban air quality, as well as reduce energy consumption.

    Simulation of the 2012 Te Maari debris avalanche: Insight into the failure mechanics and the role of the hydrothermal system
    (Elsevier B V, 2025-09) Vicente J; Mead S; Kereszturi G; Miller C
    Composite volcanoes consist of alternating layers with varying mechanical properties, which contribute to the instability of the flanks. This instability can lead to the onset of mass flows down volcanic slopes, posing significant risks to nearby populations and infrastructures. Tongariro, an active andesite volcano, experienced one of New Zealand's most recent debris avalanches at the Upper Te Maari crater on August 6, 2012. This debris avalanche, initiated simultaneously with a small-magnitude earthquake, released a volume of 7 × 105 m3 of material from the source, which by unloading the pressurised vapour-dominated hydrothermal system, led to a phreatic eruption. This paper aims to better constrain the preparatory and triggering factors, along with the failure mechanics, that led to the 2012 debris avalanche. To achieve this, we applied slope stability finite-element modelling to assess the volcanic slope's sensitivity to varying groundwater, seismic and mechanical conditions. Model results closely match the observed failure when considering the strength of hydrothermally altered rocks subjected to an increased pore pressure at shallow depth. We found that even a relatively minor rise in pore pressure, ≈ 250 kPa in the upper layers, could replicate the observed failure at Te Maari. Our simulations also reveal that this debris avalanche might be a multiple-stage failure involving the progressive sliding of two distinct blocks. These findings enhance our understanding of Tongariro's structure and improve hazard assessments for future potential collapses at Tongariro and other New Zealand volcanoes.

    The communication of volcano information in New Zealand–a narrative review
    (Taylor and Francis Group on behalf of the Royal Society of New Zealand, 2025-02-13) Das M; Becker JS; Doyle EEH; Charlton D; Clive MA; Krippner J; Vinnell LJ; Miller C; Stewart C; Gabrielsen H; Potter SH; Leonard GS; Johnston DM; Tapuke K; Fournier N; McBride SK
    Communication of volcano information is critical for effective volcanic risk management. A variety of information is communicated to inform decisions and guide actions for planning, preparedness, and response. Such information needs to be reliable, and fit-for-purpose across different stages of volcanic activity (quiescence, unrest, short or long-term eruptive stages, and the post-eruptive stage). However, an understanding of communication across these different stages of volcanic activity remains limited. We undertook a narrative review of New Zealand literature to explore what information is communicated about volcanoes, across which stages of activity and by whom. Results highlight that NZ literature only documents certain aspects of volcano information and communication, specifically regarding certain locations, stages of volcanic activity (i.e. quiescence or unrest), or hazards. Literature gaps exist regarding volcano communication during unrest and post-eruptive stages, as well as how volcano information evolves between these phases, and how decision-makers use such information. Additional work would be useful to document existing examples of volcano information for different stages of activity. Further research could help in understanding the information needs of decision-makers during each of these stages to improve information and communication.
