Acquisition procedures, processing methodologies and preliminary results of magnetic and ROV data collected during the TOMO-ETNA experiment

open access: yesAnnals of Geophysics, 2016
The TOMO-ETNA experiment was devised for the investigation of the continental and oceanic crust beneath Mt. Etna volcano and northeastern Sicily up to the Aeolian Islands, through an active source study.

Volcanic Tremor of Mt. Etna (Italy) Recorded by NEMO-SN1 Seafloor Observatory: A New Perspective on Volcanic Eruptions Monitoring

open access: yesGeosciences, 2019
The NEMO-SN1 seafloor observatory, located 2100 m below sea level and about 40 km from Mt. Etna volcano, normally records a background seismic signal called oceanographic noise.

Application of the Wiener filter to magnetic profiling in the volcanic environment of Mt. Etna (Italy)

open access: yesAnnals of Geophysics, 1996
The frequency-domain Wiener filtering was applied to magnetic anomalies in the volcanic area of Mt. Etna. This filter, under suitable conditions (additive noise, linear processing and mean-square error criterion), can furnish an effective tool for ...

Isochronal maps at Mt. Etna volcano (Italy): a simple and reliable tool for investigating large-scale heterogeneities

open access: yesAnnals of Geophysics, 1997
This paper analyses twelve etnean earthquakes which occurred at various depths and recorded at least by eleven stations. The seismic stations span a wide part of the volcanic edifice; therefore each set of direct P-wave arrival times at these stations ...

Water Vapor Tomography of the Lower Atmosphere from Multiparametric Inversion: the Mt. Etna Volcano Test Case

open access: yesFrontiers in Earth Science, 2021
Space techniques based on GPS and SAR interferometry allow measuring millimetric ground deformations. Achieving such accuracy means removing atmospheric anomalies that frequently affect volcanic areas by modeling the tropospheric delays.

The 1981 eruptive fissure on Mt. Etna: considerations on its exploration and genesis [PDF]

open access: yesInternational Journal of Speleology, 1998
This paper is targeted to an analysis of features common to various fissure caves on Mt. Etna, Sicily. The Authors report the preliminary results of the exploration carried out in the 1981 eruptive fissure, the technical problems met during the ...

Atmospheric anomalies over Mt.Etna using GPS signal delays and tomography of radio wave velocities

open access: yesAnnals of Geophysics, 2007
Due to the prominent topography of Mt. Etna, the use of satellite geodetic techniques may significantly suffer from atmospheric heterogeneities. This problem mainly affects the DInSAR technique.

Assessing the effects of “appeal to authority” in the evaluation of environmental goods. Evidences from an economic experiment in Mt Etna, Italy

open access: yesAestimum, 2020
In this study we aim to assess how public opinion perceives the value of dry-stone walls in the terraced vineyards of Mt Etna (Italy), recently named intangible cultural heritage of Humanity by UNESCO because they are an “example of human manufacture ...

A chemical threshold controls nanocrystallization and degassing behaviour in basalt magmas

open access: yesCommunications Earth & Environment, 2022
Nanocrystallization in experiments on basalt melts and glasses from Mt. Etna and Stromboli is mainly triggered by undercooling-driven oversaturation in TiO2 and FeO, which could bias viscosity measurements and affect magma dynamics during decompression.

Mt. Etna Paroxysms of February–April 2021 Monitored and Quantified through a Multi-Platform Satellite Observing System

open access: yesRemote Sensing, 2021
On 16 February 2021, an eruptive paroxysm took place at Mt. Etna (Sicily, Italy), after continuous Strombolian activity recorded at summit craters, which intensified in December 2020. This was the first of 17 short, but violent, eruptive events occurring
