The Southeast Crater of Mount Etna (Italy) was characterized by a violent eruptive activity between 26 January and 24 June 2000. This produced 64 lava fountain episodes with repose periods from 3 hours to 10 days. We estimated volume about 15–20 × 6 m at least 2–3 tephra. compared the paroxysmal volcanic its associated seismic signature: high number events highlighted strict correlation tremor activity. Seismic characteristics, such as frequency occurrence, duration fountains energy,...
Abstract Two paroxysmal explosions occurred at Stromboli volcano in the Summer 2019, first of which, on July 3, caused one fatality and some injuries. Within 56 days between two explosions, effusive activity from vents located summit area occurred. No significant changes routinely monitored parameters were detected before explosions. However, we have calculated polarization fractal dimension time series seismic signals November 15, 2018 to September 2019 recognized variations that preceded...
Abstract The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is an Italian research institution with focus on earth sciences. Moreover, the INGV operational center for seismic surveillance and earthquake monitoring in Italy a part of civil protection system as expertise seismic, volcanic, tsunami risks.INGV operates National Seismic Network other networks at national scale primary node European Integrated Data Archive archiving distributing strong-motion weak-motion recordings.

Abstract. In this work, we study a Mediterranean cyclone, Helios, which took place during 9–11 February 2023 in the southeastern part of Sicily and Malta, by multiparametric approach combining microseism results with sea state meteorological data provided wavemeter buoy, HF radar, hindcast maps satellite SEVIRI images. The sub-tropical system Helios caused heavy rainfall, strong wind gusts violent storm surges significant wave heights greater than 5 m. We deal relationships between such...
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...
Abstract 3D earthquake locations, focal mechanisms and stress tensor distribution in a 16‐month interval covering the 2018 Mt. Etna flank eruption, enabled us to investigate relationship between magma intrusion structural response of volcano shed light on dynamic processes affecting instability Etna. The likely caused tension flanks volcano, leading significant ground deformation redistribution neighbouring faults at edge Etna's unstable sector, encouraging ESE sliding eastern volcano....
<p>Instrumental seismic catalogues are an essential tool for the zonation of territory and production hazard maps. They also a valuable instrument detailed seismological studies regarding active volcanoes and, above all, interpreting magma dynamics evolution eruptive phenomena. In this paper, we show first instrumental earthquake catalogue Mt. Etna, period 2000-2010, with purpose producing homogeneous dataset 10 years observations. During period, 16,845 earthquakes have been recorded...
The persistent open-vent degassing of Mt. Etna is often punctuated by months-long paroxysmal sequences characterized episodes violent Strombolian to lava fountaining activity. Understanding these gas-fueled transitions from quiescence eruption requires routine measurement gas fluxes. Here, we report SO 2 flux measurements, obtained a permanent UV camera system, collected over two-year-long period spanning two Etna’s New South East Crater (NSEC) in December 2020/April 2021 and May/October...
Seismic site response describes how ground motion changes as seismic waves pass through different types of soil, rock, or structures. This study aims to enhance understanding local in areas with cavities, particularly lava tubes. The tubes is unique and depends on factors such the geological characteristics tube, its size, interaction surrounding materials. Lava tubes, typically cylindrical tunnel-shaped, have dimensions - length, diameter, wall thickness that influence travel around...
Soil radon emissions have been proved as a useful tool for predicting earthquakes and volcanic eruptions furthermore aided in determining the location of active faults. Continuous monitoring was carried out near Southeast Crater Mt. Etna September–November 1998, during period frequent eruptive episodes at that crater. Radon anomalies were detected when accompanying tremor became increasingly intense: no activity observed first five, weaker, episodes, whereas significant spikes preceded...
Abstract We investigated the evolution of seismicity and deformation in unstable eastern flank Etna volcano over a 30 year period (from 1980 to 2012). A significant temporal correlation has been revealed between periods acceleration intensified seismic activity by comparing along northern border (Pernicana fault system) sliding flank. Two marked phases have observed 1984–1986 years following 2002. These two are separated an intermediate phase from 1987 2001, which slowed down dropped...
After a period of mild eruptive activity, Stromboli showed between 2017 and 2018 reawakening phase, with an increase in the activity starting May 2017. The alert level volcano was raised from “green” (base) to “yellow” (attention) on 7 December 2017, small lava overflowed crater rim 15 Between July August monitoring networks recorded nine major explosions, which are serious hazard for because they affect summit area, crowded by tourists. We studied 2017–2018 phase through analysis...
