Large volcanic eruptions on Earth commonly occur with a collapse of the roof crustal magma reservoir, forming caldera. Only few such collapses per century, and lack detailed observations has obscured insight into mechanical interplay between eruption. We use multiparameter geophysical geochemical data to show that 110-square-kilometer 65-meter-deep Bárdarbunga caldera in 2014-2015 was initiated through withdrawal magma, lateral migration 48-kilometers-long dike, from 12-kilometers deep...
The 2014–2015 Holuhraun eruption in Iceland, emitted ∼11 Tg of SO2 into the troposphere over 6 months, and caused one most intense widespread volcanogenic air pollution events centuries. This study provides a number source terms for characterisation plumes large fissure eruptions, Iceland elsewhere. We characterised chemistry aerosol particle matter (PM) gas plume, its evolution as plume dispersed, both via measurements modelling. was sampled at eruptive vent, two populated areas Iceland....
We present a synthesis of diverse observations the first recorded eruption Nabro volcano, Eritrea, which began on 12 June 2011. While no monitoring volcano was in effect at time, it has been possible to reconstruct nature and evolution through analysis regional seismological infrasound data satellite remote sensing data, supplemented by petrological erupted products brief field surveys. The event is notable for comparative rarity historical eruptions region caldera systems general,...
This paper discusses disaster risk reduction (DRR) in the context of emerging geographical ideas about topologies and assemblages. It focuses on role expert advice DRR resulting political epistemological issues. The critical geography disasters still struggles to communicate with persistent scientific technical-rational approaches hazard assessment. Furthermore, recent studies have shown potential for be (mis)used purposes. Assemblage theory might useful opening up this hybrid area research,...
The 2014–2015 Bárðarbunga fissure eruption at Holuhraun in central Iceland was distinguished by the high emission of gases, total 9.6 Mt SO2, with almost no tephra. This work collates all ground-based measurements this extraordinary cloud made under particularly challenging conditions: remote location, optically dense SO2 column amounts, low UV intensity, frequent clouds and precipitation, an extensive hot lava field, developing ramparts, high-latitude winter conditions. Semi-continuous flux...
This article builds on previous work that has sought to link assemblage theory with the study of disaster risk. Specifically, we propose existing idea a ‘disaster risk management assemblage’ can be used in two ways. The first is an overall approach analysing second conceptualise assemblages as objects study. These are assemblages, or apparatuses, seek manage – but also create disasters-in-the-making. We go explore how these ideas empirical research and they help us imagine doing differently.
This paper presents the results of empirical research on Montserrat, in British West Indies, undertaken 2008–2010. It highlights challenges managing a crisis that evolved from acute to chronic over period fifteen years. In particular, considers evolution science and policy years its social cultural context. discusses relationship between different types evolving knowledges, interaction them. Finally, reflexive model is introduced draw attention some science–policy interface under high...
Paektu volcano (Changbaishan) is a rhyolitic caldera that straddles the border between Democratic People's Republic of Korea and China. Its most recent large eruption was Millennium Eruption (ME; 23 km3 dense rock equivalent) circa 946 CE, which resulted in release copious magmatic volatiles (H2O, CO2, sulfur, halogens). Accurate quantification volatile yield composition critical assessing volcanogenic climate impacts but challenging, particularly for events before satellite era. We use...
The transition from a response-based paradigm to an anticipative, prevention-based approach remains stubborn challenge in Disaster Risk Reduction (DRR). Whilst the United Nations Office for (UNDRR) has advocated latter since International Decade Natural 1990s, many countries have been slow move response-focused preventative one. policy guidelines successfully informed national DRR policies various countries; however, their further translation down regional and local level is full of complex...
Lonquimay is ranked as the 12th most dangerous volcano in Chile. Several settlements are located within 20 km with a diverse mix of residents and livelihoods. Conservation areas growing tourist economy sit alongside Indigenous groups farming. These have varied ways knowing volcanoes volcanic landscapes; this knowledge generated through lived experience, memories, collectively held imaginaries. This paper presents data collected from semi-structured interviews community members living near...
Abstract Background The overlap between physical and mental health is a common challenge for older adults, many live with co-occurring disorders. Different service models have been adopted; however, the majority provide specialist input to adults needs in acute hospital trusts. Few are available providing comprehensive secondary healthcare settings. Furthermore, little information regarding specific facing people receiving healthcare. aim of this qualitative study was determine facilitators...
Resilience plays a critical role in reducing risk and preventing disasters by enabling communities to withstand recover from the impacts of hazards. While resilience is at heart disaster reduction literature, there lack consistency defining factors that influence it. The ‘risk perception paradox’ presents phenomenon where individuals may recognise hazard poses significant threat, yet do not take action protect themselves; ‘trust’ one factor has been...
This Progress Report reviews the geographical literature concerning environmental hazards and risk focussing particularly on areas that require enhance interdisciplinary working between human physical geographers. Although there are still substantial gaps disciplinary siloes, is a growing recognition critical work vital. Key include early warning, urban planning, hazard mapping, scientific advisory processes, communication institutional geographies. We review some of this work, examine...
In this paper, we use insights from science studies to elucidate the nature of advisory in context disasters, particularly those involving geophysical hazards. We argue that there are some key differences between disaster and issues most discussed studies: they both time- space-specific constitute major social, economic scientific shocks. suggest disasters require flexible structures maximise co-production social order, present a framework for this. aim increasing resilience natural hazards...
Abstract. Early warning systems have the potential to save lives and improve resilience. However, barriers challenges remain in disseminating communicating early information institutional decision-makers, community members individuals at risk, including unequal access, insufficient understanding, inability act on information. Research was undertaken analyse understand current flood system Nepal, considering available data forecasts, flows, dissemination, decision-making for action. Data were...
An exceptional opportunity to sample several large blocks sourced from the same region of growing Soufrière Hills lava dome has documented a significant increase in presence mafic enclaves host andesite during course long‐lived eruptive episode with phases. In 1997 (Phase I) inclusions comprised ∼1 volume percent erupted material; 2007 III) deposits their volumetric abundance increased 5–7 percent. A broader range geochemically distinctive types occurs amongst enclaves. Crystal‐poor...
The 2010 eruption of Eyjafjallajökull volcano, and the social consequences across world, demonstrated some key issues in volcanological science its application. Scientists several nations were called upon to advise governments, justify models give guidance about likely future activity. This is symptomatic many other fields: scientists increasingly have a role governance, their work may be driven by questions that arise as result. article considers different national contexts challenges faced...
Eruptions at the Icelandic volcanoes of Eyjafjallajökull (2010) and Grimsvötn (2011) produced plumes ash posing hazards to air traffic over northern Europe. In imposing restrictions on traffic, regulators needed balance dangers accidents or aircraft damage against cost inconvenience travelers industry. Two surveys examined how members public viewed necessity imposed their trust in different agencies as estimators level risk. Study 1 was conducted with 213 British citizens (112 males, 101...
