Abstract. Since 1990, natural hazards have led to over 1.6 million fatalities globally, and economic losses are estimated at an average of around USD 260–310 billion per year. The scientific policy communities recognise the need reduce these risks. As a result, last decade has seen rapid development global models for assessing risk from scale. In this paper, we review literature on hazard assessments scale, specifically examine whether how they examined future projections hazard, exposure,...
Volcanoes can produce far-reaching hazards that extend distances of tens or hundreds kilometres in large eruptions, certain conditions for smaller eruptions. About a tenth the world's population lives within potential footprint volcanic and are regularly lost through activity: fatalities were recorded 18 last 20 years. This paper identifies distance distribution around volcanoes activities victims at time impact, sourced from an extensive search academic grey literature, including media...
Abstract. Regional volcanic threat assessments provide a large-scale comparable vision of the posed by multiple volcanoes. They are useful for prioritising risk-mitigation actions and required local through international agencies, industries governments to prioritise where further study support could be focussed. Most regional studies have oversimplified hazards their associated impacts relying on concentric radii as proxies hazard footprints focussing only population exposure. We developed...
Fast-moving lava flows during the 2014–2015 eruption of Fogo volcano in Cape Verde engulfed 75% (n = 260) buildings within three villages Chã das Caldeiras area, as well 25% cultivable agricultural land, water storage facilities and only road into area. The had a catastrophic impact for close-knit communities Chã, destroying much their property, land livelihoods. Volcanic risk assessment typically assumes that any object - be it building, infrastructure or agriculture path flow will...
Abstract Cataloguing damage and its correlation with hazard intensity is one of the key components needed to robustly assess future risk plan for mitigation as it provides important empirical data. Damage assessments following volcanic eruptions have been conducted buildings other structures hazards such tephra fall, pyroclastic density currents, lahars. However, there are relatively limited quantitative descriptions caused by lava flows, despite number communities that devastated flows in...
Abstract. Cities near volcanoes expose dense concentrations of people, buildings, and infrastructure to volcanic hazards. Identifying cities globally that are exposed hazards helps guide local risk assessment for better land-use planning hazard mitigation. Previous city exposure approaches have used the centroid represent an entire city, assess population proximity volcanoes. But can cover large areas populations may not be equally distributed within their bounds, meaning a accurately...
Cities near volcanoes expose dense concentrations of people, buildings, and infrastructure to volcanic hazards. Identifying urban centres exposed hazards at a global scale supports local risk assessments, better land-use planning, hazard mitigation. Previous approaches dominantly relied on city centroids assess population exposure proximity volcanoes, overlooking the spatial variability distribution within margins. In this research, firstly, we propose novel framework rank 1,106 cities...
This study introduces a unified framework for evaluating the physical impacts of earthquakes and volcanic eruptions on buildings, leveraging upon existing capabilities OpenQuake engine earthquake risk assessment various packages computing hazard footprints. We illustrate new scenario module using two case studies: VEI (Volcanic Explosivity Index) 3-4 eruption Nevado del Ruiz volcano in Colombia 6 Mount Pinatubo Philippines, employing methods simulating footprints tephra fall, lava flows,...
Abstract Tephra from large explosive eruptions can cause damage to buildings over wide geographical areas, creating a variety of issues for post-eruption recovery. This means that evaluating the extent and nature likely building future is an important aspect volcanic risk assessment. However, our ability make accurate assessments currently limited by poor characterisation how perform under varying tephra loads. study presents method remotely assess increase quantity data available developing...
The dichotomy between probabilistic and scenario-based volcanic hazard assessments stems from their opposing strengths weaknesses. quantification of uncertainty lack bias in the former is balanced against temporal narrative communicability latter. In this paper we propose a novel methodology to bridge two, deriving pseudo-probabilistic estimate suite dynamic scenarios covering multiple hazards transitions eruptive style, as designed for emergency management purposes, monogenetic field. We...
Disaster risk research's reliance on past events has proved inadequate when it comes to extreme events. This shortcoming stems from limited records (for example, due the vast differences in timescales between geological processes and human records) dynamic nature of all three components -- drivers change hazard (e.g., climate change), exposure urban growth), vulnerability aging infrastructure). paper provides a framework for modeling key unrealized through downward counterfactual changes...
Pyroclastic density currents (PDCs) that escape their confining channels are among the most dangerous of volcanic hazards. These unconfined PDCs capable inundating inhabited areas may be unprepared for these hazards, resulting in significant loss life and damage to infrastructure. Despite ability cause serious impacts, have previously only been described a limited number specific case studies. Here, we carry out broader comparative study reviews different types PDCs, deposits, dynamics as...
Hazard assessments for long-dormant volcanoes, where information is rarely available, typically have to be made rapidly and in the face of considerable uncertainty often poor information.
