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...
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...
Understanding past eruption dynamics at a volcano is crucial for forecasting the range of possible future eruptions and their associated hazards risk. In this work we use numerical models to recreate footprints pyroclastic density currents (PDCs) tephra fall from three Gede volcano, Indonesia, with aim gaining further insight into these identifying suitable source parameters hazard risk assessment. has largest number people living within 100 km any worldwide, exhibited recent unrest...
Abstract. Regional assessments provide a large-scale comparable vision of the threat posed by multiple sources and are useful for prioritising risk-mitigation actions. There is need such from international, regional national agencies, industries governments to prioritise where further study support could be focussed. Most existing studies on volcanic activity have relied concentric radii as proxies hazard footprints focused only population exposure, often using indices make first-order...
Abstract. In the wake of a volcanic eruption, rapid assessment building damage is paramount for effective response and recovery planning. Uninhabited aerial vehicles, UAVs, offer unique opportunity assessing after with ability to collect on demand imagery safely rapidly from multiple perspectives at high resolutions. this work, we established UAV-appropriate tephra fall state framework used it label ~50,000 bounding boxes around ~2,000 individual buildings in 2,811 optical images collected...

Uncrewed aerial vehicles, UAVs, offer unique opportunity assessing after with ability to collect on-demand imagery safely rapidly from multiple perspectives at high resolutions. this work, we established UAV-appropriate tephra fall state framework used it label ∼50 000 bounding boxes around ∼2000 individual buildings in 2811 optical images collected during...
Abstract We present FlowDIR, a MATLAB tool that rapidly and objectively quantifies future travel direction probabilities for topographically controlled hazardous flows, based on analysis of summit topography. FlowDIR can achieve probabilistic forecasts directions in minutes provides basis choosing the starting co-ordinates required by empirical flow models. In this work we describe development perform sensitivity to determine influence input parameters forecasted probabilities, demonstrate...
Effective risk management requires accurate assessment of population exposure to volcanic hazards. Assessment this at the large-scale has often relied on circular footprints various sizes around a volcano simplify challenges associated with estimating directionality and distribution intensity However, date, values obtained from have never been compared modelled hazard footprints. Here, we compare estimates calculated concentric radii 10, 30 100 km those simulation dome- column-collapse...
