Variations of low temperature fumaroles as a tool for detecting changes in volcanic activity state: a brief overview [PDF]

open access: yesAdvances in Geosciences, 2020
Fumarolic fields, especially those with near-surface soil temperature <100 ∘C, are very common features of active or quiescent volcanoes, with both open or closed conduits.

Attenuation of short-period seismic waves at Mt Vesuvius, Italy [PDF]

open access: yesGeophysical Journal International, 1999
We analysed short-period seismograms from about 250 very local events recorded by a network of high dynamic range short-period seismic stations deployed on Mt Vesuvius to estimate the site-corrected short-period seismic attenuation. We calculated QC− 1, the inverse of the quality factor for coda waves, for short lapse times (12 s), and QP− 1 and QS− 1,

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...

Late Holocene landscape evolution of the Gulf of Naples (Italy) inferred from geoarchaeological data

open access: yesJournal of Maps, 2017
The mapping of landforms in the Gulf of Naples is fundamental to understanding the recent evolution of this perithyrrenian basin controlled by several systems of Quaternary faults and characterised by the presence of the Campi Flegrei and Somma Vesuvius ...

New magnetotelluric soundings in the Mt. Somma-Vesuvius volcanic complex: preliminary results

open access: yesAnnals of Geophysics, 2000
During 1997 ten magnetotelluric (MT) soundings were recorded in single-site mode above the Mt. Somma-Vesuvius volcanic area. A first campaign of MT measurements was carried out, during spring, by the researchers of the University of Padua with their MSPM

Exploring the Transferability of Image‐Based Algorithms for River Plastic Detection: The Value of Small Mixed Data Sets

open access: yesWater Resources Research, Volume 62, Issue 4, April 2026.
Abstract Using large image data sets has been the conventional strategy to improve object detection, but it increases annotation effort and training cost and does not guarantee robust transfer to new sites. Here we quantify the value of a small, diverse training set for floating macroplastic detection by jointly evaluating performance, computational ...

Seismic activity and thermal regime of low temperature fumaroles at Mt. Vesuvius in 2004-2011: distinguishing among seismic, volcanic and hydrological signals

open access: yesAnnals of Geophysics, 2013
Seismological, soil temperature and hydrological data from Mt. Vesuvius are collected to characterize the present-day activity of the volcanic/hydrothermal system and to detect possible unrest-related phenomena. We present patterns of seismicity and soil

Landslide Character and Hydrological Thresholds for Slope Failure Initiation on Volcanic Scoria Slopes: Case Study From Mt Hobson/Ōhinerau, Auckland, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Rainfall‐induced landslides involving on Auckland Volcanic Field scoria cones are highly unusual, compared with widespread landsliding in the surrounding Auckland clay‐rich residual soils. Indeed, while Auckland can suffer from thousands of rainfall‐induced shallow landslides from severe storms at subdecadal timescales, these are usually limited to ...

Decoding Past Microbial Communities Shifts Induced by Natural and Anthropogenic Disturbance Events Through Extracellular DNA

open access: yesMolecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT Coastal marine ecosystems face escalating threats from multiple anthropogenic stressors, including the release of industrial contaminants. Despite decades of industrial activity impacting marine ecosystems, long‐term effects on microbial communities and related key ecological functions remain unclear.

Magnetic measurements at Naples in the XIX century

open access: yesAnnals of Geophysics, 1997
Measurements of elements of the Earth's magnetic field started in Naples in 1837 by the Astronomical Observatory. Declination and inclination daily averages were regularly published from 1840. In 1839 Macedonio Melloni was called in Naples by the Bourbon
