Among the volcanic processes, the formation of pyroclastic density currents (PDCs) poses a significant threat to residential buildings because of the large dynamic overpressures generated during the explosion. This study introduces a simple mechanics-based method, called STAM-PYR (STructural Assessment Method for PYRoclastic density currents), for the structural assessment of infilled reinforced concrete buildings subjected to PDCs. The STAM-PYR method allows to predict damage evolution as a function of dynamic overpressure intensity, accounting for the contribution of both structural and nonstructural components as well as typical failure modes that can develop in existing RC buildings. Furthermore, it accounts for the variation in the overpressure profile by dynamically updating the load distribution depending on the progressive failure of infill panels and closures. A suitable damage scale is also introduced to facilitate future multi-risk comparisons. The method is exemplified via application to a case study of a typical 1970s RC building, comparing the results to existing literature to demonstrate the enhanced accuracy of the proposed approach in capturing the complex interactions between PDC loadings and building response. STAM-PYR offers a practical and scalable tool to support probabilistic volcanic risk modeling, vulnerability mapping, and emergency planning, especially in urban areas at high risk of explosive eruptions. By enabling a more accurate quantification of structural vulnerability to PDCs, the methodology enhances current capabilities in disaster mitigation, crisis management, and long-term risk-informed land-use strategies.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"124 ","pages":"Article 105546"},"PeriodicalIF":4.2,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study embarks on a mission to assess flood inundation mapping and the impact on agricultural and built-up areas in four districts: Gomati, Sipahijala, South Tripura, and West Tripura, during the severe monsoon floods of August 2024. Harnessing the power of Sentinel-1 Synthetic Aperture Radar (SAR) and EOS 04 MSR SAR data, this study unveil near real-time insights into the flood's extent and effects. By utilizing Google Earth Engine (GEE) and SigmaSAR V3.1, satellite datasets have been processed and analyzed in a very short time. The integration of SAR imagery with Random Forest land use and land cover (LULC) classification techniques proves invaluable for mapping flood inundation and assessing damage. The results reveal that out of 85021.46 ha (ha) of agricultural land, 10,510.32 ha were inundated, with Gomati and West Tripura facing the greatest challenges, where 13 % of the total farmland was flooded. In the realm of built-up areas, 928.72 ha of the total 75180.26 ha were affected, with Gomati District experiencing the most significant inundation, marking 1.5 % of its built-up regions flooded.

SVs' stress was primarily linked to working conditions (e.g., long hours, task overload) and organizational aspects (e.g., unclear responsibilities, communication), alongside task-specific exposure such as encounters with severely injured individuals. These challenges were particularly pronounced among SVs without institutional affiliation (e.g., Red Cross). Only a minority actively sought external help (MHPSS), while most relied on social support, discussions with fellow SVs, and the meaningfulness of their work for coping. On an organizational level, MHPSS availability and working conditions varied widely, as they largely developed independently of authorities and emergency personnel (AEP). Altruistic motivation, well-planned coordination, and individuals with relevant knowledge, particularly regarding AEP, were identified as crucial resources for managing stress and mitigating risk factors. Findings suggest that SVs require better preparation and support for psychosocial stress management, with SV coordinators playing a key role in implementing qualified MHPSS during and after disasters. To effectively address SVs' needs, a transformation in the design and delivery of MHPSS may be necessary.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"124 ","pages":"Article 105534"},"PeriodicalIF":4.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143927635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our approach uses statistical and spatial techniques, including Spearman correlations, bivariate choropleth maps, and regression models. Results show that vulnerability and resilience are related but distinct concepts. The correlation between their indices is weak (r = 0.06), but there are significant correlations between specific elements.

Spatial regressions show a local R² value of 0.74 between the resilience index and vulnerability dimensions. Some elements of vulnerability are also significantly correlated to certain variables related to flash flood risk. These are mostly the exposure component (r = 0.59 for the population at risk) and the institutional dimension (r = −0.48 for the total flood indemnities provided by the insurance company). With a local R² of 0.85, the vulnerability and resilience indices show significant spatial regression with the critical infrastructure at risk.

Interdependencies between infrastructure systems and the environment compound consequences at vulnerable locations but can be harnessed to maximize operational efficiency, recovery capability, and long-term sustainability. Threats, both emergent and systemic, have propagated beyond historical norms, exposing the limitations of hazard-specific resilience approaches. These approaches, by their nature, rely on predefined scenarios that fail to capture the full complexity of cascading failures, novel threat combinations, and the dynamic evolution of risks over time, especially in the cases where environment is affected. This leaves critical gaps in planning, response, and recovery, as systems designed around specific hazards are often unable to adapt to disruptions that fall outside their narrowly defined parameters, resulting in unanticipated vulnerabilities and slower recovery trajectories. We propose a paradigm shift toward threat-agnostic resilience, emphasizing adaptability to unforeseen hazards through modularity, distributedness, diversity, and plasticity. These principles foster system-wide robustness by enabling critical functions to persist despite unpredictable challenges. This framework also accounts for the interdependencies between resilience strategies and environmental outcomes, ensuring that adaptability to unforeseen hazards is balanced with sustainability goals. Resilience characteristics, such as modular design and distributed systems, shape patterns of resource use, energy efficiency, and ecological impacts across systems. By identifying methods to assess and optimize these trade-offs, we provide actionable insights for designing infrastructure that simultaneously enhances resilience and minimizes environmental burdens.

By applying fixed effects models, we find that rainfall shocks, including excess and lack of rain, significantly worsen socioeconomic conditions, pushing poor urban households further down into poverty. These events disproportionately affect women, who are overrepresented in the informal labor market, and households living in highly susceptible areas, where exposure to environmental hazards intersects with economic vulnerability.

To tackle them, a shift in wildfire governance has been advocated: from fighting fire towards a ‘coexisting with fire’ strategy that emphasises fostering long-term, community-led transformations to reduce wildfire risk. This topic has received scant attention, particularly in Southern Europe, a region also grappling with land abandonment and an ageing, dwindling population. This article explores how such transformations unfold at the local level by exploring ten local responses to the catastrophic 2017 wildfires in Portugal, which caused over a hundred casualties and countless damages. Using a collective case study approach and qualitative research methods, the article analyses the practices, motivations, opportunities, and challenges underpinning four groups of initiatives: creating defensible areas around villages, reforesting communal land, goat grazing, and water infrastructures. These aim to simultaneously enhance security, reduce wildfire risk, and revitalise local economies and ecologies. Key elements facilitating these transformations include leadership, particularly by newcomers and local mayors, external funding, and volunteer work. However, challenges such as financial constraints, social conflicts, and land fragmentation challenge the sustainability of these efforts. While context-specific, our analysis suggests that the post-wildfire recovery phase can catalyse significant socioecological transformations in depopulated rural areas of Southern Europe, highlighting the need for further research to support communities in reducing wildfire risk. Ultimately, the study reveals how transforming landscapes and restoring practices of care might bring into being safer, more liveable, less flammable futures in devitalised rural areas amidst the growing threat of wildfires.</div></div>","PeriodicalId":13915,"journal":{"name":"International journal of disaster risk reduction","volume":"124 ","pages":"Article 105536"},"PeriodicalIF":4.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
