Here, we use 39 SAR backscatter images from the COSMO-SkyMed satellite to measure the extent and surface properties of lava flows from the 2017 to 2019 eruption of Erta 'Ale volcano, Ethiopia. Using pairs of SAR backscatter images, we produce change difference images and map the flow outlines. We observe both increases and decreases in backscatter, which we attribute to differences in surface roughness. These manual-derived flow maps produced detailed outlines that are consistent with results obtained from other datasets, such as coherence. We then apply a sequential analysis technique, CUSUM, to corrected backscatter timeseries and find that it can automatically identify flows with an accuracy of 88%. Automated detection provides an objective and repeatable alternative to manual mapping. We find that at least four pre-eruption acquisitions are required as a baseline to achieve a robust classification. Our results demonstrate that SAR backscatter timeseries analysis can be used to characterise lava flow emplacement and surface evolution in remote volcanic environments.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-026-01984-8.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"88 6","pages":"60"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13156144/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147870255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The event produced a short-lived sustained eruption column, with ash dispersal and fallout primarily towards the north and east of the volcano, and the formation of two new craters at Hayli Gubbi's summit. Ash from the northern lobe has a basaltic (trachy)andesitic composition. The eruption was preceded, in July 2025, by a dyke intrusion originating from neighbouring Erta Ale volcano, migrating over 30 km southward and intercepting Hayli Gubbi where inflation occurred. Renewed ground deformation started again in Erta Ale ~ one month before the Hayli Gubbi eruption during which a sudden reservoir contraction and a new collapse caldera was formed. Synchronous deformation signals suggest both volcanoes are structurally coupled. Intense degassing continues at Hayli Gubbi during the months after the eruption. We provide the first accounts of the eruption's development, assembling on-the-ground observations, geophysical and geochemical data and satellite imagery to characterize the physical features of the eruption and its impact. Whilst impact remained limited, partly due to low exposure in the remote region, the eruption did cause disruption to international air traffic.

Accurate ash dispersal forecasting is crucial for hazard mitigation, yet current models primarily rely on eruption source parameters, such as particle size distribution, while largely neglecting evolving atmospheric ash distributions. Turbulence-driven particle interactions generate dense clusters that travel faster than isolated particles, shortening the residence time of fine ash and potentially boosting collision and aggregation rates. These processes remain poorly constrained. Here, we present an experimental framework to quantify clustering in controlled ash columns over particle volume fractions <i>φ</i> = 10^-5-10^-2. Using Laacher See ash (1000-63 µm), we vary particle size distributions and release rates, acquire high-speed laser-illuminated videos for particle tracking, and apply Voronoi tessellation to quantify preferential concentration. We find that particle-driven convection intensifies with decreasing size, while varying <i>φ</i> modulates clustering across all sizes < 500 µm. Clustering produces strongly inhomogeneous distributions within the column, enhances particle-particle interactions, and likely promotes aggregation. It also affects settling, as smaller particles within clusters can settle faster than larger, unclustered ones, thus challenging traditional assumptions that link particle size to settling velocity. Incorporating these dynamics into dispersal models, and accounting for their signatures in remote-sensing retrievals, should improve forecast accuracy and refine our understanding of volcanic ash transport and deposition.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-025-01933-x.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"88 2","pages":"15"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12823729/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146054997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deformation also informs on volcano flank instability, which presents a major hazard in the event of a complete or partial collapse of the edifice, which may further trigger a tsunami if the volcano is located near the sea. We explore InSAR datasets to investigate surface deformation of 20 potentially hazardous coastal volcanoes in Southeast Asia. We find that over 90% of them exhibit signs of persistent or episodic surface deformation. Most volcanoes experience line-of-sight (LOS) increase with displacement rates spanning a broad range and reaching up to 29 cm/yr at Ruang. These are either steady, or experience distinct acceleration periods, lasting for several months to years following increased volcanic activity measured as the volcanic radiative power (VRP) and reported periods of unrest or eruptions. We attribute the majority of observed deformation to gravity-driven processes and cooling of young surface deposits. Analysis of displacement components shows subsidence for all cases of LOS increase, coupled with varying horizontal displacements showing either (i) convergence, representing inwards displacements of the flanks due to volume loss by gravitational compaction and cooling contraction, (ii) divergence, representing outwards spreading due to instability of the volcano flanks via surficial downslope flank creep or fault sliding or (iii) near-unilateral horizontal displacements across most of the edifice, representing sliding via a deep detachment fault. We suggest that the horizontal component of InSAR deformation on volcanic edifices may be used to quickly assess the dominant deformation patterns. Applying this concept, we identify potential flank instability at four volcanoes (Anak Krakatau, Lewotobi, Sirung and Ulawun), which may pose future collapse hazards. This work offers new insights into the types and rates of volcano flank deformation, demonstrates a direct link between increased volcanic activity levels and deformation rates, and provides an improved comparative basis to other volcanic regions worldwide.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-025-01915-z.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"88 1","pages":"4"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12700928/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145758450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In continental monogenetic settings, these eruptions can occur on short timescales and with short notice after long quiescence. Their deposits are often quickly destroyed or buried as the eruption progresses, limiting understanding of eruption triggers and hazards uniquely garnered from these tephra layers and lavas. The ~37 ka Budj Bim Volcanic Complex (BBVC) in the active intracontinental monogenetic Newer Volcanics Province (NVP), southeastern Australia (~4.5 Ma to present), is a rarely preserved volcanic fissure system that provides new insight on how magma ascent dynamics impact eruptions. The BBVC comprises a 2.2 km long array of basaltic scoria cones, spatter cones, an elongate open crater with steep inward-sloping walls and a substantial lava-tube-fed flow field. Newly logged eruption sequences, petrography and geochemical analysis reveal five eruption stages, involving vent-shifting along a dyke-fed fissure, and rapid changes in eruption styles between Strombolian and micro-Plinian activity interspersed with concurrent and intermittent phreatomagmatism. The eruption culminated in the establishment and then breach of an elongate lava lake, feeding the > 30 km long culturally significant Tyrendarra lava flow (UNESCO World Heritage site). The BBVC eruption would have evolved similarly to the 2014-2015 Bárðarbunga-Holuhraun fissure eruption in Iceland, but with increased complexity due to its intraplate continental setting and feeder dyke interaction with aquifers and near-surface faults, resulting in greater level of phreatomagmatism and explosion depths potentially down to 320 m. This finding must be considered to improve future eruption scenario assessments in the NVP and builds new understanding of complex volcanic fissure eruption behaviour that can be applied to similar systems around the world.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-026-01967-9.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"88 4","pages":"45"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13038471/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147610688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigate how soil alteration influences near-surface gas flow by combining in situ petrophysical measurements with horizontal and vertical subsurface gas-concentration profiles at the Rotokawa geothermal field, New Zealand. These data are compared against unoccupied aerial system (UAS) thermal surveys of collapse structures across the field. Soil permeability at Rotokawa ranges from 8.7 × 10^-14 to > 6.5 × 10^-13 m², highlighting strong meter- to decimeter-scale heterogeneity in shallow soil properties. Pumice-rich horizons are the main conduits for CO₂ and CH₄ flow, whereas clay-rich horizons locally act as semiconfining layers that promote CO₂ accumulation and lateral diversion (leading to concentrations of > 4 × 10⁴ ppm). Since CO₂ does not condense under near-surface conditions, the clay layers promote horizontal flow along permeable beds until gas encounters a high-permeability escape route or collapse-related discontinuity. Collapse structures locally disrupt and reorganize flow by acting as conduits or sinks that focus, capture, or redistribute gases near their margins. The gas profiles reveal patterns consistent with a shallow gas-steam decoupling zone in which steam condensation may contribute to sealing processes, as previously observed in steam-heated geothermal systems worldwide. These coupled effects of soil type and structural and alteration controls explain the spatial heterogeneity of surficial degassing at Rotokawa and provide a framework for interpreting evolving degassing patterns in similar steam-heated geothermal systems. In the context of the reported decrease in diffuse CO₂ emissions at Rotokawa, progressive shallow sealing and gas refocusing may have contributed to apparent changes in emission patterns, alongside reservoir processes, recharge variability, environmental effects, and methodological uncertainty.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-026-02002-7.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"88 7","pages":"73"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13287163/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148320832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that fissure locations are heavily influenced by topography, including features parallel to fissure strike and features formed during previous eruptions. The maximum fire-fountain heights ranged from 56 m during the January 2024 eruption to 133 m during the August 2024 eruption. Variations in fire-fountain heights in a single eruption between different fissure segments, and through time, appear to primarily be controlled by surface vent size and dike pressurisation, both of which increase mass eruption rate and lead to higher fountains. Understanding the controls on fissure location highlights areas most vulnerable to future fissure opening, which can help inform ongoing hazard assessment and risk mitigation. Digital video capture of future eruptions from multiple angles would augment monitoring and help refine models of fire-fountain evolution.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-026-02006-3.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"88 8","pages":"89"},"PeriodicalIF":2.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13356074/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148431549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decompression experiments were carried out to elucidate the kinetics of H₂O bubble nucleation on crystals of different sizes. Samples used were mixtures of hydrated rhyolitic melt and populations of augite or hornblende crystals of < 20 µm or 20-40 µm. We found that bubbles nucleated on surfaces of both types of crystals at supersaturation pressures ≤ 10 MPa, which is a small fraction of the supersaturation needed to homogeneously nucleate H₂O bubbles in the melt. Very small crystals (< 5-10 µm) will nucleate only ~ 1 bubble, whereas on larger crystals, the number of bubbles that nucleate at a given supersaturation increases with an increased crystal surface area. In addition, the number of bubbles that nucleate on crystals of a given surface area increases with increasing supersaturation, indicating that the distance between nucleation sites decreases with increased supersaturation. We propose that the closer spacing of nucleation sites at higher supersaturation arises from the competition between bubble nucleation rate and the rate of H₂O diffusion. Based on these results, we develop a modified heterogeneous nucleation rate equation that accounts for the control of crystal surface area on heterogeneous bubble nucleation and the resulting bubble number density generated.
