Forecasting the future path and/or behavior of an active lava flow is challenging because topography is often poorly constrained and lava has a complex rheology and emplacement history. Preserved lavas are an important source of information which, combined with observations of active flows, underpins conceptual models of lava flow emplacement. However, the value of preserved lavas is limited because pre-eruptive topography and, thus, syn-eruptive lava flow geometry are usually not known. Here, we use tree-mold data to constrain pre-eruptive topography and syn-eruptive lava flow geometry of the July 1974 flow of Kīlauea (USA). Tree molds, which are formed after advancing lava encloses standing trees, preserve the lava inundation height and the final preserved thickness of lava. We used data from 282 tree molds to reconstruct the temporal and spatial evolution of the ~ 2.1 km-long July 1974 flow. The tree mold dataset yields a detailed dynamic picture of staged emplacement, separated by intervals of ponding. In some ponded areas, flow depth during emplacement (~ 5 m) was twice the preserved thickness of the final lava (2-3 m). Drainage of the ponds led to episodic surges in flow advancement, decoupled from fluctuations in vent discharge rate. We infer that the final breakout occurred after the cessation of fountaining. Such complex emplacement histories may be common for pāhoehoe lavas at Kīlauea and elsewhere in situations where the terrain is of variable slope, and/or where lava is temporarily perched and stored.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-025-01817-0.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"87 4","pages":"30"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11958447/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143774905","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 extent and success of such mixing ultimately control the physical properties (e.g. density and viscosity) of the magma, the eruptive conditions, and thus the associated hazards. Analogue experimental studies have previously investigated magma interactions in plumbing systems typically with pipe-like or chamber-like geometries (i.e. cylindrical or cuboidal respectively) and immiscible fluids that represent magma mingling. However, these findings are difficult to extrapolate to high aspect ratio geometries typical of dykes that characterise fissure systems. Here, we present results from a high aspect ratio experimental setup to explore magma mixing within dykes. Using an array of miscible fluid pairs, representing magmas of differing composition, we found that flow is initially localised towards the centre of the system and mixing occurs at the interface between the two fluids, spreading laterally out over time. The mixing interface is generally greater, and mixing is more rapid when the starting physical properties of the two fluids are more similar. Furthermore, a dyke-like geometry facilitates mixing to a greater degree relative to a chamber-like system. We explore the implications of the mixing dynamics on diffusive and crystal exchange between magmas, the transport of magmas through the crust, and the evolution of physical and chemical properties of interacting magmas. The mixing ratio trends of our experimental data are similar to near-real time geochemical mixing data from the Kīlauea 2018 eruption, suggesting a future avenue for understanding the complexities of mixing during magma ascent.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-025-01809-0.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"87 4","pages":"29"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11976769/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144013821","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}

These data consist of both continuous and discrete measurements and observations, which are carried out by ground-based networks and remote sensing instruments, or during field surveys and laboratory analyses. Many types of volcanological research are largely based on the accurate sampling of rocks erupted during past and ongoing volcanic activity. Each sample represents a \"physical object\" which should be identified and archived before part of it is removed for analytical purposes. In this context, we recommend assigning the collected samples unique and persistent identifiers, such as the International Generic Sample Number (IGSN). However, although the IGSN allows recording the most essential information of the collected samples (e.g. geographic location, sampling method, and collector), the predefined metadata fields are not exhaustive for volcanic samples, which require additional information such as type and timing of the eruptive event, sample temperature, and texture. Here we design the guidelines necessary to facilitate communication between and search of multiple sample repositories and databases run by disparate institutions. To this aim, we build a metadata model, which integrate the IGSN metadata with supplementary information necessary for the monitoring and research activities carried out by the volcanological community. The long-term curation of collected materials is an important investment for the future. Indeed, these collections are a resource for the production of volcanological data, they reduce the need for repeated sampling, they preserve samples that can no longer be collected, and they allow repeat analyses to be made. The primary aim of this work, based on discussion within the EUROVOLC project, is to provide the basic information for populating a relational database structure in the future for the description of different volcanic samples, physically located in different physical repositories and institutions, in order to facilitate future sharing between different groups of scientists and more complete volcanological studies, by means of the proposed metadata structure.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"87 5","pages":"32"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11982162/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144052895","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 used X-ray computed microtomography to investigate vesicle textures in tephra from the 2021 Tajogaite eruption (La Palma, Spain) and the relationship between these pore network parameters and eruptive style. We report a 3D dataset of pore network parameters for lapilli clasts collected throughout the eruption, associated with different eruptive styles (ash-rich jets, lava fountains, Strombolian activity). In clasts from Strombolian activity, the lower vesicle number density (VND) and tortuosity factor (<i>m</i>) suggests that there are fewer vesicles and that the channels which connect them are less tortuous than in clasts from fountain and ash-rich jet activity, favouring a lower degree of gas-melt coupling and thus, more efficient outgassing. Instead, for clasts of lava fountain and ash-rich jet activity, the higher VND and <i>m</i> suggest a higher number of vesicles connected by more tortuous channels, promoting some degree of gas-melt coupling and thus, less efficient outgassing. However, in clasts from ash-rich jets, the presence of narrower channels, as suggested by the lower throat-pore size ratio, favours a greater degree of gas-melt coupling with respect to fountain activity, leading to magma fragmentation.

This included heightened volcanic tremor, the initiation of a new heating phase at the crater lake Te Wai ā-moe, and increases in gas emissions. The unrest featured highly periodic, low-frequency earthquakes known as 'drumbeats'. These signals have been observed around the world to often precede and/or accompany the ascent of magma and volcanic eruptions. However, Ruapehu did not erupt in 2022. In this work, approximately 43,000 discrete drumbeat events and 89 days of continuous volcanic tremor were identified over the 121-day unrest period. These were analysed in the time, amplitude, and frequency domains. We argue that increases in volcanic tremor, lake temperatures, and gas throughput are the result of magma ascent into the shallow system immediately prior to or contemporaneous with the onset of tremor. We construct a conceptual model for the generation of drumbeat, tremor, and lake temperature signals that consists of shallow magma storage, a gas cavity, a permeable cap, and the crater lake. The presence of repetitive drumbeat earthquakes results from transient sealing and failure within the fracture pathways of the permeable cap. This is driven and regulated primarily by pressure accumulation from persistently degassing magma and the strength of the sealing mechanism.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-025-01823-2.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"87 6","pages":"44"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12089182/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121351","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 eruption ended when fluxes dropped to less than 6% of their fitted maximum value, providing a useful benchmark to compare with other eruptions.

The advent of fibre-optic submarine cables in the 1990s catalyzed a global digital revolution. Today, a network of > 1.7 million kilometres of fibre-optic cables crosses the oceans, carrying more than 99% of all digital data traffic worldwide and trillions of dollars in financial transactions. These arteries of the global internet underpin many aspects of our daily lives, and are particularly important for remote island communities that rely on submarine cables for telemedicine, e-commerce, and online education. However, these same remote communities are often in seismically and volcanically active regions and can be prone to natural hazards that threaten their critical subsea communication infrastructure. This vulnerability was acutely exposed in January 2022, when the collapse of the eruption plume of Hunga Volcano triggered fast-moving density currents that damaged Tonga's only international submarine cable, cutting off an entire nation from global communications in the midst of a volcanic crisis. Here, we present a new comprehensive analysis of damage to subsea communications cables by volcanic events from around the world, and document their diverse impacts. Examples include (i) severing of the telegraph cable crossing the Sunda Strait by a tsunami triggered by the 1883 Krakatau eruption, Indonesia; (ii) ocean-entering pyroclastic density currents, lahars, and landslides during the 1902 eruptions of Mount Pelée, Martinique, that damaged six telegraph cables; (iii) destruction of a cable landing station on Montserrat by a pyroclastic density current in 1997; (iv) submarine slope failure at Kick 'em Jenny, Grenada, that damaged two fibre-optic cables; (v) complete loss of the telecommunications network due to power outages following the 2000 eruption of Miyake-jima, Japan; and (vi) disruption to subsea cables resulting from the 2021 eruption of La Soufrière, St. Vincent. We find that the causes of damage typically relate to secondary hazards that occur not only at the same time as the eruption climax, but also some time after. There does not appear to be an explosivity intensity threshold for cable-damaging events; however, the extent of damage may be related to the original volcano morphology (e.g. steep slopes), spatial location (e.g. near the coast or partially/totally submerged), the eruption size or explosivity, and/or volcanic depositional processes involved. Based on these diverse case studies, we present lessons learned for enhancing telecommunications resilience, and discuss how subsea cables themselves can be used as sensors to improve understanding and early warning of volcanic hazards, potentially filling a monitoring gap for remote island communities.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s00445-025-01832-1.</p>","PeriodicalId":55297,"journal":{"name":"Bulletin of Volcanology","volume":"87 6","pages":"51"},"PeriodicalIF":3.6,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12133983/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144235987","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}

Although several geochronological studies have been carried out in the last three decades, the eruptive history of the central zone of the arc remains poorly documented, preventing analysis of the initiation of volcanism of the whole arc. In this study, we present new K–Ar ages obtained from this central area, referred to as the Quito segment. These results were then incorporated into an updated comprehensive geochronological database of about 250 ages, allowing us to describe, at the arc scale, the spatial and temporal evolution of Quaternary volcanism in Ecuador. About eighty Quaternary volcanoes have been identified in the Ecuadorian Andes, 45 of which have been radioisotopically dated and/or identified as active or potentially active. The volcanic arc developed in three stages, characterized by an increase in the total number of active volcanoes. During the oldest Plio-Early Pleistocene stage, documented volcanic activity was mostly concentrated in the Eastern Cordillera of the Quito segment, with minor effusive eruptions in the southern Back-Arc. Since ~ 1.4 Ma, activity has spread to the surroundings of the Quito segment, and new edifices also appeared in the Western Cordillera and the Inter-Andean Valley. Towards the end of this intermediate stage (i.e., ~ 800 ka), volcanism occurred in isolated areas north and south of the Inter-Andean Valley. Finally, the late and current has been characterized by a remarkable increase in volcanic activity since ~ 600 ka. About 50 volcanoes were active during this stage. The spatial distribution of the Ecuadorian arc volcanism seems to be guided by deep mechanisms (i.e., slab geometry and age, amount and composition (fluids and melts) of slab input, mantle heterogeneities) and old crustal tectonic structures of the Western Cordillera, while neotectonics seems to influence the development of stratovolcanoes.
