Since the 1970's, about 50 radio-isotopic ages have been determined on Etna volcanics using different techniques: Th-U and K/Ar.Unfortunately, these cannot be readily used to constrain new stratigraphic setting of volcano, because uncertainty in sample locations or, sometimes, large errors affecting calculated ages. For this reason a program dating applying 40Ar/39Ar incremental heating technique date groundmass basaltic samples has carried out from 2002.Forty (22 which are publication) were...
On 21 May 2023, a hidden eruption occurred at the Southeast Crater (SEC) of Etna (Italy); indeed, bad weather prevented its direct and remote observation. Tephra fell toward southwest, two lava flows propagated along SEC’s southern eastern flanks. The monitoring system Istituto Nazionale di Geofisica e Vulcanologia testified to occurrence. We analyzed seismic infrasound signals constrain temporal evolution fountain, which lasted about 5 h. finally reached Etna’s summit weeks later found an...
In July and August 2019, two paroxysmal eruptions dramatically changed the morphology of crater terrace that hosts active vents Stromboli volcano (Italy). Here, we document these morphological changes, by using 2259 UAS-derived photographs from eight surveys Structure-from-Motion (SfM) photogrammetric techniques, resulting in 3D point clouds, orthomosaics, digital surface models (DSMs) with resolution ranging 8.1 to 12.4 cm/pixel. We focus on evolution volcanic features volume changes upper...
Volcanic Ballistic Projectiles (VBPs) ejected during explosive eruptions represent a significant hazard to people approaching the craters of active volcanoes. Recently, several models have been proposed simulate trajectories VBPs, thus contributing assessing associated hazards. However, these mostly rely on field data, which may not be readily available. Indeed, often large size and weight VBPs make their transportation laboratory for detailed physical measurements extremely challenging....
Mount Etna, one of Europe's most active volcanoes, has experienced a variety eruption settings throughout its history, including summit, flank, and eccentric eruptions. In this study, we provide detailed analysis the structures formed during 1947 eruption, which occurred along NE Rift, drawing on historical accounts, archival images, contemporary field drone data. Photogrammetric processing 1932 1954 aerial photos enabled us to identify map before in order focus effects direction dyke...
We present a 1:10,000 scale map of the coseismic surface ruptures following 26 December 2018 Mw 4.9 earthquake that struck eastern flank Mt. Etna volcano (southern Italy). Detailed rupture mapping is based on extensive field surveys in epicentral region. Despite small size event, we were able to document faulting for about 8 km along trace NNW-trending active Fiandaca Fault, belonging Timpe tectonic system volcano. The mapped are characterized most cases by perceivable opening and dominant...
UAVs have become a useful tool for natural hazard monitoring. In volcanic areas, they allow wider observations of the eruptive behaviour, with no risk operator. The SfM technique enables obtaining orthoimages lava flows and DEM in short time. These data are also to estimate flow volumes mass output rate characterizing an eruption. We present results ten UAV surveys made during after 30 May – 6 June 2019 eruption Etna volcano, projecting time context back until 1999. Orthoimages taken on...
On 16 November 2006 a flank collapse affected the unstable eastern slope of South‐East Crater (SEC) Mount Etna. The occurred during one paroxysmal events with sustained strombolian activity that characterized August–December eruption and was triggered by erosion loose, hydrothermally altered material steep south‐east sector SEC from outpour lava. produced debris avalanche involved both lithic juvenile resulted in deposit emplaced on volcano up to 1.2 km away source. total volume estimated be...
We provide a database of the surface ruptures produced by 26 December 2018 Mw 4.9 earthquake that struck eastern flank Mt. Etna volcano in Sicily (southern Italy). Despite its relatively small magnitude, this shallow caused about 8 km faulting, along trace NNW-trending active Fiandaca Fault. Detailed field surveys have been performed epicentral area to map and characterize their kinematics. The show dominant right-oblique sense displacement with an average slip 0.09 m maximum value 0.35 m....
Abstract At active volcanoes recurring eruptive events, erosive processes and collapses modify the edifice morphology impact monitoring hazard mitigation. Etna volcano (Italy) between February October 2021, 57 paroxysmal events occurred from South-East Crater (SEC), which is currently its most summit crater. Strombolian activity high lava fountains (up to 4 km) fed flows towards east, south south-west, caused fallout of ballistics (greater than 1 m in diameter) within 1–2 km SEC. The...
Infrasound is increasing applied as a tool to investigate magma dynamics at active volcanoes, especially open-vent such Mt. Etna (Italy), which are prodigious sources of infrasound. Harmonic infrasound signals have been used constrain crater dimensions and track the movement within shallow plumbing system. This study interprets remarkable systematic change in monotonic preceding lava fountaining episode on 20 February 2021. We model changing tones (0.7 3 Hz fundamental frequency) rise column...
Determining the volume of various types products a highly frequent active volcano can be very difficult, especially if most them are deposited on growing volcanic cone. The New South-East Crater (NSEC) Mt Etna, Italy, may considered one best case studies because tens paroxysmal episodes which it produced in last few years. On 25-26 October 2013, lava fountain at NSEC magma jets up to 500 m high, maximum ~8 km high column, multilobate flow field 1.3 1.5 long, and almost 30 growth height...
In this body of work, we showcase a historic virtual geotrail on the eastern flank iconic Mt. Etna volcano (Italy), along series outstanding geological sites and features subsequent to an important eruption that took place in 1928. A geohistoric account such major eruption, is great interest, since it only event 1669 have caused destruction town (Mascali) region. Volcanologists, educators, lay public, tourists explorers can now access “virtual geostops” belonging geotrail, “visitors”...
