    Using citizen data to understand earthquake impacts: Aotearoa New Zealand’s earthquake Felt Reports
    (Massey University, 2021-12) Goded T; Tan ML; Becker JS; Horspool N; Canessa S; Huso R; Jonathan H; Johnston D
    Aotearoa New Zealand's national seismic network, GeoNet, administers Felt Reports, including the Felt RAPID and Felt Detailed databases, which are being collected at present. NZ has a long tradition of using earthquake Felt Reports provided by the public to analyse the damage caused by moderate to large earthquakes. From traditional paper-based Felt Reports to current online reports (using the GeoNet website or a mobile app), researchers have been using such data to obtain a geographical distribution of the damage caused by an earthquake and to assess what actions people take during shaking. Felt Reports include questions on people's reactions, indoor and outdoor effects of earthquake shaking, building damage, and tsunami evacuation. The database of long online Felt Reports (Felt Classic between 2004 and 2016 and Felt Detailed from 2016 to the present) comprises over 930,000 reports from more than 30,000 earthquakes. Current research being carried out using this data includes: 1) updating of the NZ Ground Motion to Intensity Conversion Equation and Intensity Prediction Equation, 2) understanding human behaviour for earthquakes and related hazards such as tsunami, 3) developing a predictive model of human behaviour in earthquakes to estimate injuries and fatalities, and 4) improving public education. This paper summarises the history of NZ earthquake Felt Reports as well as the research currently being carried out using this data. Finally, we discuss how citizen science helps in the understanding of earthquake impacts and contributes to the aim of improving Aotearoa New Zealand's resilience to future events.

    Getting through: Children's effective coping and adaptation in the context of the Canterbury, New Zealand earthquakes of 2010-2012
    (Massey University, 1/06/2017) Tarrant RA; Mooney M; Paton D; Johal S; Johnston D
    Children may experience distress and can become vulnerable as the result of a disaster. However, recent research suggests that children experiencing such adversity can address adversity by employing their capacities to adapt. The present study investigates how children coped effectively with a disaster, the Canterbury, New Zealand earthquakes of 2010-2102, and identifies strategies, processes, and resources that promoted effective coping and adaptation. Semistructured interviews took place with 38 children from three different age groups, with 31 parents, and with 11 teachers and principals from five Canterbury schools. Children were interviewed twenty months after the first earthquake, during an ongoing aftershock sequence, and six selected children were interviewed again sixteen months later. Thematic analysis of interview data identified multiple, inter-connected coping strategies and resources in the children that were fundamental to their post-disaster adaptation. Children coping effectively employed a repertoire of diverse coping strategies in a flexible and pertinent manner. Three key strategies employed by the children were emotional regulation, positive reframing, and problem-solving. Sixteen months later, the children had shifted their focus away from coping with earthquakes to coping with everyday problems. It is expected that findings from this study will contribute to future interventions for promoting effective coping and adaptation by children.
