Abstract Stromboli, the northernmost island of Aeolian archipelago, is known for its persistent volcanic activity over last several centuries and cone which, on clear days, surmounted by a gas plume rising from summit. The hosts two settled areas: village Stromboli ( c. 500 inhabitants) to NE that Ginostra 40 SW, both situated along coast. In summer number residents grows considerably, reaching 5000 people. This paper provides description present reassesses hazards basis data new monitoring...
Textures, petrography and geochemical compositions of products emitted during the onset 2011–2012 submarine eruption (15 October, 2011) off coast El Hierro have been investigated to get information on interaction mechanism between first rising magma crust as well storage plumbing systems beneath volcano. Studied consist 5–50 cm bombs with an outer black greenish, vesicular bulk basanite composition containing pumiceous xenoliths (xenopumices). Our results show that xenopumices are much more...
Abstract Stromboli volcano (Italy), always active with low energy explosive activity, is a very attractive place for visitors, scientists, and inhabitants of the island. Nevertheless, occasional more intense eruptions can present serious danger. This study focuses on modeling estimation their inter-event time temporal rate. With this aim we constructed new historical catalog major explosions paroxysms through detailed review scientific literature last ca. 140 years. The includes calendar...
In December 2015, four violent explosive episodes from Mt. Etna's oldest summit crater, the Voragine, produced eruptive columns extending up to 15 km a.s.l. and significant fallout of tephra a hundred vent. A combined textural compositional study was carried out on pyroclasts three deposits sampled volcano at 6 14 crater. Ash fractions (Φ = 1-2) were investigated because these grain sizes preserve magma properties unmodified by post- emplacement processes. Results used identify processes...
Abstract In this study, we combine reconstructions of volcanological data sets and inputs from a structured expert judgment to produce first long‐term probability map for vent opening location the next Plinian or sub‐Plinian eruption Somma‐Vesuvio. past, volcano has exhibited significant spatial variability in location; can exert control on where hazards materialize (particularly pyroclastic density currents). The new mapping been performed through (i) development maps with Gaussian kernel...
Over the past decades, significant efforts have been made to understand nature, dynamics and evolution of volcanic systems. In parallel, continuous demographic expansion extensive urbanization areas increased exposure our society these natural phenomena. This increases need improve capacities accurately assess projected hazards their potential socioeconomic environmental impact, Antarctica sub-Antarctic islands are no exception. More than a hundred volcanoes identified in Antarctica, some...
Abstract. Identifying key environmental changes is important to understand the processes that govern Earth’s climate system and all its interacting components. Micropaleontological proxies are one of most used proxies, being able connect abundances species in physiochemical characteristics environment. In this context, foraminifera have been extensively due their preservation potential. However, little attention has paid properties whole foraminiferal community that, turn, can be depict a...
The 10 February 2022 pyroclastic avalanche at Mt. Etna represents a significant example of high-mobility granular flow occurring basaltic volcanoes. While such phenomena are typically associated with more explosive volcanic systems, their occurrence underlines relevance for hazard assessment in environments dominated by effusive and mildly eruptions.This study focuses on triggered the gravitational collapse Southeast Crater’s (SEC) during an intense lava fountaining episode. event...
Gravity-induced pyroclastic density currents (PDCs) can be produced by the collapse of volcanic crater rims or due to gravitational instability materials deposited in proximal areas during explosive activity. These types PDCs, which are also known as “glowing avalanches”, have been directly observed, and their deposits widely identified on flanks several volcanoes that fed mafic intermediate magmas. In this research, suitability landslide numerical models for simulating gravity-induced PDCs...
<p>A shallow water eruption started on October 10, 2011, ~2 km south off the coast of El Hierro (Canary Islands, Spain). The lasted about five months and ended by early March 2012. Three unrest preceded this event with more than 10,000 localized earthquakes up to 6 cm vertical ground deformation. In Canary is first be monitored network Instituto Geográfico National (IGN) since very beginning seismic unrest. This provided unprecedented time series that include geophysical (seismic...
Abstract We present a paleomagnetic and rock magnetic data set from two long sediment cores collected Bellsund Isfjorden contourite drifts located on the eastern side of Fram Strait (western Spitsbergen margin). The gave opportunity to define behavior past geomagnetic field at high latitude constrain palaeoclimatic events that occurred in time framework spanning marine isotope stage 3 Holocene. A high‐resolution age model was reconstructed by coupling 26 radiocarbon ages relative...
Abstract We report the discovery of an important new cryptotephra within marine sediments close to Cape Hallett (northern Victoria Land), in western Ross Sea, Antarctica. The is fully characterized for its texture, mineralogy and major- trace-element data obtained on single glass shards. On basis geochemical composition, unequivocally correlated with proximal deposits explosive eruption poorly known Mount Rittmann volcano, situated northern Land. also a widespread tephra layer, which was...
Open conduit volcanoes like Stromboli can display elusive changes in activity before major eruptive events. Starting on December 2020, volcano displayed an increasing activity, that 19 May 2021 led to a crater-rim collapse, with pyroclastic density currents (PDCs) spread along the barren NW flank, entered sea and ran across it for more than 1 km. This episode was followed by lava flow output from crater rim lasting few hours, another phase of June 2021. These episodes are potentially very...
We present the results of tephrochronology study a 14.49 m long marine sediment core (TR 17–08) collected in Edisto Inlet, Ross Sea (Antarctica). The contains four cryptotephra layers at 55–56, 512–513, 517–518, and 524–525 cm depth, which have been characterised by detailed description texture, mineral assemblage, single glass shards major trace element geochemistry. age model investigated sedimentary sequence, based on radiocarbon dating, indicates that topmost correlates with widespread...
