Analysis of their deposits provides valuable insights into their internal dynamics and informs numerical simulations of pyroclastic density currents which underpin many volcanic hazard assessments. We present PDCD-DAT, a global database of pyroclastic density current deposit characteristics compiled from peer-reviewed literature. The database includes both quantitative datasets (e.g., grain size, density, bedform dimensions, thickness) and qualitative descriptors (e.g., sedimentary structures, lithofacies). PDCD-DAT includes data from 85 source publications, covering 97 eruptions or eruptive phases, and 214 individual depositional units from 55 globally distributed volcanoes. Eruptions recorded in the database range from VEI 1-8. We highlight examples of potential applications of the database, which include (i) comparison of single deposit case studies to global datasets, (ii) informing input parameters and conditions for numerical and analogue models of pyroclastic density currents, (iii) validation of numerical and analogue models against a wide variety of natural case study deposit architectures, and (iv) estimating hazard impact metrics of pyroclastic density currents from past eruptions. We show that the database represents a useful tool for improving our ability to model pyroclastic density currents, predict their associated hazards, and understand the relationships between the internal dynamics of pyroclastic density currents and the properties of their deposits. PDCD-DAT is integrated with the FlowDat Mass Flow Database, which provides a sustainable platform for the database. We aim for PDCD-DAT to be expanded in the future through addition of pyroclastic density current deposit datasets from new field studies conducted by the volcanology research community.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1186/s13617-026-00167-6.</p>","PeriodicalId":37908,"journal":{"name":"Journal of Applied Volcanology","volume":"15 1","pages":"9"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13158253/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147934178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Garibaldi (<i>Nch'</i> <i>k</i> <i>ay')</i> volcano, British Columbia, Canada.","authors":"Sara Osman, Thomas J Jones, Yannick Le Moigne, Melanie Kelman","doi":"10.1186/s13617-026-00173-8","DOIUrl":"10.1186/s13617-026-00173-8","url":null,"abstract":"<p><p>Following explosive volcanic eruptions, hazard from tephra fall can be widespread. Based on the geological record of past eruptions and risk to population and infrastructure, Mt. Garibaldi volcano (<i>Nch'</i> <i>k</i> <i>ay'</i>) in British Columbia has been assigned the highest threat ranking of any Canadian volcano. However, until this contribution no hazard map exists for the volcano. In our study, we formed a government-university partnership and modelled tephra dispersion for Volcanic Explosivity Index (VEI) 3 and VEI 4 scenarios for Mt. Garibaldi to produce probabilistic tephra fall hazard maps. We found significant tephra impacts (loads ≥ 0.1 kg m^- 2 which can cause skid risks on roads and disrupt airports) extend over 810 km² for the VEI 3 scenario and 9360 km² for VEI 4 (with 50% probability of exceedance). Tephra loads that may cause infrastructure damage (≥ 1 kg m^- 2) cover 250 km² and 1670 km² for the VEI 3 and VEI 4 scenarios, respectively. We combined our results into a single tephra ground accumulation hazard map and information brief. This is the first probabilistic volcanic hazard map using well-constrained source parameters for a Canadian volcano. Further work with emergency managers, will build on this map, toward consideration of appropriate mitigation measures.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at https://doi.org/10.1186/s13617-026-00173-8.</p>","PeriodicalId":37908,"journal":{"name":"Journal of Applied Volcanology","volume":"15 1","pages":"14"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13582183/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148991803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Disaster researchers increasingly use participatory research methods to recognize and amplify these missing voices. Arts-based participatory methods promise both empowerment for local people and opportunity for researchers to work creatively and reflexively. They also present challenges of participation and representation. This paper describes the process of co-producing a \"zine\" describing local people's experiences of eruptions of Fuego volcano (Guatemala) and the impacts of these eruptions that caused disaster. The zine is narrated by local people and is illustrated by the researcher (me) who conducted semi-structured interviews of residents to better understand their experiences. The motivations for this project are explored together with lessons learned in turning participatory research design into practice. Taking a constructively critical perspective on my process, I document challenges I encountered in community participation and representation and discuss how they may be addressed in project design and execution. I also describe the tensions and value in occupying both researcher and artist roles. This paper describes an open method of research exploration where the opportunities and limitations of visual representation to contribute to shared and widening understandings of volcanic disaster experience is documented and reflected upon.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1186/s13617-025-00149-0.</p>","PeriodicalId":37908,"journal":{"name":"Journal of Applied Volcanology","volume":"14 1","pages":"1"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11807920/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the load may be reduced significantly by tephra sliding on pitched roofs. We present small-scale laboratory tests to investigate tephra sliding behaviour on metal, fibre cement sheet and tile roofing. We tested 10–30 cm thicknesses for dry and wet deposits of pumice, scoria and basaltic ash. We found that tephra did not slide on roof pitches ≤ 15° for coarse-grained deposits and ≤ 12° for dry ash. Thin deposits of wet ash were stable at pitches ≤ 30°. In addition, tephra was mainly shed on pitches ≥ 32° for metal roofs and ≥ 35° for fibre cement and tiles. Using these results, we have produced an initial set of sliding coefficients for tephra for simply pitched roofs that can be used to help prioritise roofs for clearing during an eruption and assist in designing roofs to withstand tephra fall.","PeriodicalId":37908,"journal":{"name":"Journal of Applied Volcanology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135635248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FlowDIR can achieve probabilistic forecasts of future travel directions in minutes and provides a basis for choosing the starting co-ordinates required by empirical flow models. In this work we describe the development of FlowDIR, perform a sensitivity analysis to determine the influence of input parameters on forecasted probabilities, and demonstrate its effectiveness in the retrospective forecasting of travel directions for block-and-ash flows and lava flows at three volcanoes with different summit morphologies (Shinmoedake, Colima and Merapi). In all case studies, the higher probability flow directions identified using FlowDIR agreed with the travel direction of historically observed flows. Given its intuitive outputs and rapid execution time, FlowDIR can be used to supplement existing modelling strategies for hazard assessment of topographically controlled hazardous flows prior to and during crisis. We demonstrate this by coupling FlowDIR output probabilities with an empirical hazard model to estimate probability of block-and-ash flow inundation at Gede volcano, Indonesia.","PeriodicalId":37908,"journal":{"name":"Journal of Applied Volcanology","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136098186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
