“…This volcano gave its name to the Strombolian explosive activity, with mild explosions typical of basaltic explosive volcanism, that often feature at the summit of Yasur (Vanuatu), Piton de la Fournaise (La Réunion), Shishaldin (Alaska), Fuego (Guatemala), Nyiragongo (R.D. Congo), Masaya (Nicaragua), Turrialba (Costa Rica), Etna (Italy), Kilauea (Hawaii), and several other open conduit basaltic volcanoes [15][16][17][18][19][20][21][22][23][24].…”

Variable Magnitude and Intensity of Strombolian Explosions: Focus on the Eruptive Processes for a First Classification Scheme for Stromboli Volcano (Italy)

Strombolian activity varies in magnitude and intensity and may evolve into a threat for the local populations living on volcanoes with persistent or semi-persistent activity. A key example comes from the activity of Stromboli volcano (Italy). The “ordinary” Strombolian activity, consisting in intermittent ejection of bombs and lapilli around the eruptive vents, is sometimes interrupted by high-energy explosive events (locally called major or paroxysmal explosions), which can affect very large areas. Recently, the 3 July 2019 explosive paroxysm at Stromboli volcano caused serious concerns in the local population and media, having killed one tourist while hiking on the volcano. Major explosions, albeit not endangering inhabited areas, often produce a fallout of bombs and lapilli in zones frequented by tourists. Despite this, the classification of Strombolian explosions on the basis of their intensity derives from measurements that are not always replicable (i.e., field surveys). Hence the need for a fast, objective and quantitative classification of explosive activity. Here, we use images of the monitoring camera network, seismicity and ground deformation data, to characterize and distinguish paroxysms, impacting the whole island, from major explosions, that affect the summit of the volcano above 500 m elevation, and from the persistent, mild explosive activity that normally has no impact on the local population. This analysis comprises 12 explosive events occurring at Stromboli after 25 June 2019 and is updated to 6 December 2020.

“…Pyroclastic flows are frequently produced by eruptive activity of Volcán de Fuego [Naismith et al 2019]. However, the estimated 15.1 million cubic meters of pyroclastic flow material deposited in Las Lajas on 3 rd June [Albino et al 2020] was exceptionally large for a single eruption. It was more than double the average volume of pyroclastic flows registered since 1999 [Ferres and Escobar-Wolf 2018].…”

Volcán de Fuego (Guatemala) is an active stratovolcano capable of large (VEI~ě2) explosive eruptions like that of 3 rd June 2018, which triggered pyroclastic flows that devastated the community of San Miguel Los Lotes and caused hundreds of fatalities and severe long-term socioeconomic impacts. Future volcanic risk mitigation efforts are likely to involve temporary evacuation of local communities, the success of which requires cooperation between locals, scientists, and decision-makers. However, locals' experiences of eruptive activity, and how these experiences influence their responses to evacuation, have not been studied in detail. In 2019 we conducted an investigation of these themes through qualitative research methods involving semi-structured interviews that focussed on direct experience as opposed to volcanic risk perception. We found substantial differences between scientists' and locals' observations of Fuego's activity. Furthermore, a clear disparity emerged between communities on Fuego's west and east flanks in terms of direct prior experience of eruptions and communication with authorities. These findings have serious implications for future evacuation efforts at Fuego and at other highly populated active volcanoes. Resumen El Volcán de Fuego (Guatemala) es capaz de erupciones catastróficas como la del 3 de junio de 2018, cuando flujos piroclásticos destruyeron la comunidad de San Miguel Los Lotes y causaron numerosos muertos e impactos socioeconomicos severos en el largo plazo. Al futuro, la mitigación del riesgo volcánico implicará la evacuación de las comunidades locales, cuyo éxito requiere la cooperación entre autoridades y la población. Sin embargo, se sabe poco sobre cuales son las experiencias de actividad eruptiva de estos grupos, y cómo estas experiencias afectan sus respuestas a la evacuación. En 2019 realizamos una investigación de estos temas y encontramos diferencias significativas entre las observaciones científicas y de la población de la actividad de Fuego. Además, surgió una disparidad entre las comunidades en diferentes flancos del volcán en términos de la experiencia vivida de las erupciones anteriores y de la comunicación con autoridades. Estos resultados tienen implicaciones para los futuros esfuerzos de evacuación en Fuego y en volcanes análogos.

“…On 27 May 2010, Pacaya (Guatemala) experienced the collapse of materials deposited in a ravine (Figure 5C) after a flank eruption (300 m below the summit), causing both a directed blast and debris avalanche, which were then followed by enhanced explosive activity (the most intense eruption since 1964; Wardman et al, 2012;Bollasina, 2014). More recently, a similar valley-infill collapse at Fuego (Guatemala) on 3 June 2018, affected Barranca Las Lajas (Figure 5D; 15 × 10 6 m 3 ), and the hot avalanche mixed with PDCs traveled about 12 km to San Miguel de los Lotes, killing hundreds of people (Albino et al, 2020). Collapse scars from small-scale landslides of this type have distinctive parallel FIGURE 2 | Basaltic volcanism in arc settings.…”

Volcanic Lateral Collapse Processes in Mafic Arc Edifices: A Review of Their Driving Processes, Types and Consequences

et al. 2021

Volcanic cones are frequently near their gravitational stability limit, which can lead to lateral collapse of the edifice, causing extensive environmental impact, property damage, and loss of life. Here, we examine lateral collapses in mafic arc volcanoes, which are relatively structurally simple edifices dominated by a narrow compositional range from basalts to basaltic andesites. This still encompasses a broad range of volcano dimensions, but the magma types erupted in these systems represent the most abundant type of volcanism on Earth and rocky planets. Their often high magma output rates can result in rapid construction of gravitationally unstable edifices susceptible both to small landslides but also to much larger-scale catastrophic lateral collapses. Although recent studies of basaltic shield volcanoes provide insights on the largest subaerial lateral collapses on Earth, the occurrence of lateral collapses in mafic arc volcanoes lacks a systematic description, and the features that make such structures susceptible to failure has not been treated in depth. In this review, we address whether distinct characteristics lead to the failure of mafic arc volcanoes, or whether their propensity to collapse is no different to failures in volcanoes dominated by intermediate (i.e., andesitic-dacitic) or silicic (i.e., rhyolitic) compositions? We provide a general overview on the stability of mafic arc edifices, their potential for lateral collapse, and the overall impact of large-scale sector collapse processes on the development of mafic magmatic systems, eruptive style and the surrounding landscape. Both historical accounts and geological evidence provide convincing proofs of recurrent (and even repetitive) large-scale (>0.5 km3) lateral failure of mafic arc volcanoes. The main factors contributing to edifice instability in these volcanoes are: (1) frequent sheet-like intrusions accompanied by intense deformation and seismicity; (2) shallow hydrothermal systems weakening basaltic rocks and reducing their overall strength; (3) large edifices with slopes near the critical angle; (4) distribution along fault systems, especially in transtensional settings, and; (5) susceptibility to other external forces such as climate change. These factors are not exclusive of mafic volcanoes, but probably enhanced by the rapid building of such edifices.
