Residents of two North Island, New Zealand, communities were surveyed in March 1995 to measure their understanding of volcanic hazards. This was repeated in November 1995, following the Ruapehu eruptions of September‐October 1995. Both communities were subjected to intense media coverage during the 1995 Ruapehu eruption. Whakatane was spared any direct effects, whereas Hastings experienced the hazard directly, in the form of ash falls. Only Hastings’ respondents showed a significant change in threat knowledge and perceived volcanic risk. While experiencing the direct and indirect impacts of the 1995 Ruapehu eruption may make subsequent warnings and information releases more salient, thereby enhancing the likelihood of engaging in successful protective actions or other forms of response, the characteristics of hazard impacts may increase susceptibility to a “normalisation bias”, reducing future community preparedness.

Purpose – The research was carried out in order to study the composition of minerals, content of total-K, total-Ca, total-Mg, and exchangeable of K, Ca, Mg in volcanish ash from Sinabung volcano eruption.

Design/Methodology/Approach – The volcanic ash material in amount of 5 kg was collected from the depth of 0–20 cm and 21–41 cm. Mineral composition was determined by using line counting method; total contents of K, Ca, and Mg were measured by HCl 1N extraction, and exchangeable of K, Ca, and Mg was measured by NH₄OAc 1N pH 7.0 extraction.

Purpose – The results depicted in volcanic ash layer at the depth of 0–20 cm found some minerals such as plagioclase (34%), hypersthene (9%), augite (3%), hornblende/amphibole (5%), and volcanic glass (1%). These minerals were also found in different amounts at a depth of 21–41 cm. Hypersthene and amphibole were higher and augite was lower at a depth of 0–20 cm than 21–41 cm. The total content of K, Ca, and Mg was found to be 2.27%, 8.12%, and 2.28%, respectively, at a depth of 0–20 cm. The exchangeable of K, Ca, and Mg was found in an amount of 1.89 me/100 g, 20.71 me/100 g, and 1.62 me/100 g, respectively. The total content of K, Ca, and Mg was not available to plants but could potentially be as a source of plant nutrient after weathering while exchangeable form can be uptaken by plant directly.

Research Limitations/Implications – Based on the composition of the minerals, total, and exchangeable of K, Ca, and Mg that the material of volcanic ash, it could potentially be used as source of fertilizers.

Originality/Value – The composition of primary minerals contained in volcanic ash and to know the amount of elements K, Ca, and Mg-associated minerals either in total or exchange.

This paper summarizes research involving a multidisciplinary team of volcanologists and social scientists. It describes collaboration in relation to social and physical risk and vulnerability following the Mount Ruapehu eruptions of 1995‐1996. This work stresses a key role for such multidisciplinary teams in reducing the social impact of volcanic hazards through assisting communities, organizations, and individuals following an eruption and, importantly, during quiescent periods. We present an overview of a multidisciplinary approach and related research. In stressing the role of the physical science community in managing societal hazards and risk, the paper addresses how this role can be enhanced through collaboration with social scientists and others. The emphasis here is the facilitation of volcanological knowledge and expertise in threat communication, mitigation, community development, emergency planning, and response management. Our research has examined mechanisms for integration, multi‐disciplinary training, and preparing volcanologists for the social demands encountered in playing an active crisis management role. One area of overlap that can tie together disciplines and assist the public is the idea that volcanic activity and the related uncertainties are, at their essence, simply problems that with increasingly integrated efforts likewise have increasingly attainable solutions.

Uneven distribution and mistarget beneficiaries are among problems encountered during post-disaster relief operations in 2010 Mount Merapi eruption. The purpose of this paper is to develop an empirically founded agent-based simulation model addressing the evacuation dynamics and to explore coordination mechanism and other promising strategies during last-mile relief delivery.

An agent-based model which was specified and parameterized by empirical research (interviews and survey) was developed to understand the mechanism of individual decision making underlying the evacuation dynamics. A set of model testing was conducted to evaluate confidence level of the model in representing the evacuation dynamics during post-disaster of 2010 Mount Merapi eruption. Three scenarios of last-mile relief delivery at both strategic and operational levels were examined to evaluate quantitatively the effectiveness of the coordination mechanism and to explore other promising strategies.

Results indicate that the empirically founded agent-based modeling was able to reproduce the general pattern of observable Internal Displaced Persons based on government records, both at micro and macro levels, with a statistically non-significant difference. Low hazard perception and leader-following behavior which refuses to evacuate are the two factors responsible for late evacuation. Unsurprisingly, coordination through information sharing results in better performance than without coordination. To deal with both uneven distribution and long-term demand fulfillment, coordination among volunteers during aid distribution (at downstream operation) is not sufficient. The downstream coordination should also be accompanied with coordination between aid centers at the upstream operation. Furthermore, the coordination which is combined with other operational strategies, such as clustering strategy, using small-sized trucks and pre-positioning strategy, seems to be promising. It appears that the combined strategy of coordination and clustering strategy performs best among other combined strategies.

The significant role of early evacuation and self-evacuation behavior toward efficient evacuation indicates that human factor (i.e. hazard perception and cultural factor) should be considered in designing evacuation plan. Early warning system through both technology and community empowerment is necessary to support early evacuation. The early warning system should also be accompanied with at least 69 percent of the population performing self-evacuation behavior for the effective evacuation. As information sharing through coordination is necessary to avoid redundant efforts, uneven distribution and eventually to reduce unmet demand, the government can act as a coordinating actor to authorize the operation and mobilize the resources. The combination of coordination and another strategy reducing lead time such as clustering analysis, thus increasing responsiveness, is seemly strategy for efficient and effective last-mile relief distribution.

Literature on coordination is dominated by qualitative approach, which is difficult to evaluate its effectiveness quantitatively. Providing realistic setting of the evacuation dynamics in the course of the 2010 Mount Merapi eruption, the empirically founded agent-based model can be used to understand the factors influencing the evacuation dynamics and subsequently to quantitatively examine coordination mechanisms and other potential strategies toward efficient and effective last-mile relief distribution.

Despite striving for resilience and a sustainable urban future, European cities face a multitude of crisis caused by both natural and human-induced risks. This paper asks two key questions: How have cities experienced and managed crises situations they encountered? and What are the plans and actions for embedding sustainability at a local level within a clear decision-making structure? Hence, it aims to examine urban resilience in the context of urban crisis and the associated health concerns that took place because of crisis situations, while identifying sustainable urban development initiatives and strategies that were conceived and implemented beyond crisis.

An evidence-based analytical approach is undertaken following two lines of inquiry. The first is case-based and identifies 11 cities that have experienced crisis situations and a further 10 cities that have instigated urban resilience strategies. The second is theme-based and engages with identifying strategies relevant to sustainable urban development at city and project levels. The outcomes of the two lines of inquiry are verified by mapping the lessons learned from the analysis to recent international guidance and a further co-visioning workshop with 6 experts.

The evidence-based analysis reveals key lessons which were classified under two primary types of findings: (a) lessons learned for a future urban resilience resulting from the 1st line of Inquiry (case-based) and (b) lessons learned for a future sustainable urban development resulting from the 2nd line of inquiry (theme-based). The verified lessons provide four areas that can be utilised as key priorities for future urban resilience and sustainable urban development including (a) Governance, effective communication, and decision making for city resilience and urban sustainability; (b) the social dimension of resilience and participatory practices for sustainable urban development; (c) from implicit strategies for health to positive impact on health; and (d) diversification of initiatives and localisation of sustainable development endeavours.

There is always limitation on what a bibliometrics analysis can offer in terms of the nature of evidence and the type of knowledge generated from the investigation. This limitation manifests in the fact that the analysis engages with the body of knowledge but not based on engaging physically or socially with the contexts within which the cases took place or through empirical investigations including systematic observations, focused interviews, and attitude surveys. While the study does not generate empirical findings, the rigour of the bibliometrics analysis offers a credible and reliable evidence on how cities experienced and managed crises situations and their current plans and priority actions for embedding and localising sustainable development measures.

This research conveys significant implications for policy, practice, and action in that it crystalises the view that understanding urban resilience and sustainability, at the city or urban level, requires coupling the two. The findings offer a solid foundation for a more contextualised, evidence-based examination of urban resilience and sustainability during and beyond crisis. Highlighting urban and health challenges that emerged from experienced crisis situations, how these were managed and developing an understanding of sustainable urban development and local resilience strategies elucidate insights that can be adopted and acted upon by city councils and built environment practitioners.

The analysis provides comprehensive insights into urban resilience and sustainable urban development at both city and continental Europe scales in the form of key lessons that represent the first step towards developing rudiments for building a better urban future. Little is known about resilience and sustainability at these scales. The originality of this work lies in the breadth and depth for capturing an inclusive understanding of urban resilience and sustainable urban development based on systematic inquiry and scrutinising the body of knowledge emerged over the past 2 decades.

Corpus Linguistics is the study of large, computer‐held bodies of text, or ‘corpora’. In the last five years, this approach to language study has become increasingly popular among linguists, and developments in computing technology and software and in storage mechanisms like CD are making it possible even for the individual PC user. The aim of the linguist is to describe the language, and corpus linguistics reflects the shift in academic focus from the brain to the text as the appropriate source of information. A description derived by introspection will tend to be idiosyncratic and partial, since no individual has total awareness of how they or others use language. A description based on the observation of appropriate corpus data, on the other hand, can provide a broader view of language use, including statements about the relative typicality of individual features based on their frequency of occurrence in the corpus.

The purpose of this paper is to highlight the importance of a comprehensive global database on volcanic unrest (WOVOdat) as a resource to improve eruption forecasts, hazard evaluation and mitigation actions.

WOVOdat is a centralized database that hosts multi-parameter monitoring data sets from unrest and eruption episodes of volcanoes worldwide. Its online interface (https://wovodat.org/) allows interactive data analysis and comparison between volcanoes and eruption styles, which is needed during volcanic crises, as well as to perform basic research on pre-eruption processes, teaching and outreach.

WOVOdat aims to standardize and organize the myriad of monitoring data types at the global scale. Users can compare changes during a crisis to past unrest episodes, and estimate probabilities of outcomes using evidence-based statistics. WOVOdat will be to volcanology as an epidemiological database is to medicine.

The success of eruption forecast relies on data completeness, and thus requires the willingness of observatories, governments and researchers to share data across the volcano community.

WOVOdat is a unique resource that can be studied to understand the causes of volcanic unrest and to improve eruption forecasting.

WOVOdat is the only compilation of standardized and multi-parameter volcano unrest data from around the world, and it is freely and easily accessible through an online interface.

While a considerable body of work concerning citizens’ perceptions of risk for volcanic hazards has been done in the United States and New Zealand, no comparable study has focused on residents near Italy’s two major volcanoes: Vesuvio and Etna. This survey study, involving 174 participants, focused on various measures of risk perception, feelings of personal vulnerability to the volcanic threat, and confidence in government officials’ preparedness for potential eruptions. Although it was expected that due to a recent eruption of Etna, residents there would have higher levels of perceived risk than those at Vesuvio, findings mostly demonstrated the reverse. Additionally, residents living in the highest risk areas at Vesuvio demonstrated low levels of awareness concerning evacuation plans and low levels of confidence in the success of such plans.

This paper seeks to review the geophysical threats generated by volcanic activity and reports on the technological and social management techniques available to counter those threats.

The information presented was derived from a review of case studies of response to volcanic eruptions in the USA, Europe and Japan. The studies reviewed included both technical papers from geologists and volcanologists and research by social scientists.

The unique relationship between human settlements and volcanoes was described. This was done in the context of special features of volcanic hazards that set them apart from other natural hazards: time frame, multiple impacts, magnitude of destructive potential and predictability. Based on pairing geophysical threats with human safety concerns, three critical social management techniques were described: public education, access controls and evacuation systems. The social science and geophysical principles that underlie the effectiveness of these techniques are described.

The review brings together the results of numerous case studies over the years and highlights the hazard management issues that were common across them. Then, with respect to each of the techniques identified, a critique of issues associated with implementation was conducted that draws upon both the geophysical literature and social science literature. In particular, patterns of citizen resistance to public education, access controls and evacuation are described and approaches to implementation that minimize such resistance are suggested.

There are many discussions in the geophysics literature of the types and nature of volcanic eruptive behavior. In the social science literature there are discussions of public education strategies for hazards, controlling access to dangerous locations and evacuation systems. This paper pairs geophysical threats with appropriate techniques for protecting populations, specifically within the unique context of volcanic eruptions. There is also discussion of common problems that have arisen when the different techniques have been used in the past and suggestions for ways to avoid those problems. The paper is aimed at professional emergency managers and planners who are faced with managing dangers to populations from volcanicity.
