The roots of Mt. Vesuvius deduced from gravity anomalies

Mineralogy and Petrology, 2001
The structures of the Somma-Vesuvius volcanic complex are modelled on the basis of the interpretation of gravity anomalies obtained from data available in the literature and acquired along a new profile along the coastline from Naples to Castellammare di Stabia.

The seismic crises at Mt. Vesuvius during 1995 and 1996

Physics and Chemistry of the Earth, Part A: Solid Earth and Geodesy, 1999
Abstract The seismicity which affects Mt. Vesuvius is, at present, the only clear indicator of the volcano dynamics. In the last years, two periods of increased seismic activity occurred (August–October 1995 and March–May 1996). This seismicity was detected by the 10 analog stations of the Permanent Seismic Network as well as by up to 7 three ...

Combined TEM-MT investigation of shallow-depth resistivity structure of Mt Somma-Vesuvius

Journal of Volcanology and Geothermal Research, 2004
The conductivity structure of the top 2 km of the crust is examined using data from collocated magnetotelluric (MT) and time-domain electromagnetic (TDEM) soundings across the Vesuvius volcano. The MT data were corrected for static shift using dual-configuration TDEM data. The TEM and MT data were jointly inverted to yield 1D models while the TE and TM

A metallogenic survey of alkalic rocks of Mt. Somma-Vesuvius volcano

Mineralogy and Petrology, 2001
Somma-Vesuvius is an alkaline volcano whose products (pumice, scoria and lava) have alkaline (Na2O + K2O) contents between 6 and 16 wt%, Mg number

Small scale shallow attenuation structure at Mt. Vesuvius, Italy

Physics of the Earth and Planetary Interiors, 2006
Abstract We present a high resolution 3D model of S-wave attenuation ( Q S − 1 ) for the volcanic structure of Mt. Vesuvius. Data from 959 waveforms relative to 332 volcano-tectonic earthquakes located close to the crater axis in a depth range between 1 and 4 km (below the sea level) recorded at 6 three-component seismic stations were ...

Thermal and geochemical constraints on the ‘deep’ magmatic structure of Mt. Vesuvius

Journal of Volcanology and Geothermal Research, 2004
Abstract A review of available and new isotopic data on rocks from Mt. Vesuvius together with geophysical and mineralogical data allow us to define a ‘deep’ complex magmatic reservoir where mantle-derived magmas arrive, stagnate and differentiate, and to constrain a thermal model, which describes the history and present state of the reservoir and its

Mechanical Stability Of Mt. Vesuvius Volcano: Effects Of Asymmetries On The Stress Field

Surveys in Geophysics, 2000
The effect of nonaxisymmetric elasticheterogeneities on the mechanical stability of a nearly axisymmetricvolcanic structure, with particular reference to Mt. Vesuvius (Italy) is investigated. This is done solving numerical models using a finite element codein the framework of linear elasticity.

Diagnosis of Time of Increased Probability (TIP) for Volcanic Earthquakes at Mt. Vesuvius

pure and applied geophysics, 2006
The possibility of intermediate-term earthquake prediction at Mt. Vesuvius by means of the CN algorithm is explored. CN was originally designed to identify the Times of Increased Probability (TIPs) for the occurrence of strong tectonic earthquakes, with magnitude M ‡ M0, within a region a priori delimited.

Ground deformations on Mt. Vesuvius from 1977 to 1981

Bulletin Volcanologique, 1981
The results of a ground deformation study (1) of Vesuvius are reported. The study is a part of the geophysical program for the surveillance of this extremely dangerous active volcano.

The geochemical evolution of the Mt. Somma-Vesuvius volcano

Mineralogy and Petrology, 2006
This work integrates new geochemical data with the numerous published analyses on rocks from the Mt. Somma-Vesuvius volcano. New quantitative models for the evolution of magma source regions and magma at different depths are proposed. The origin of the Somma-Vesuvius parental magma is modeled as 0.05–0.1 melt fractions of a MORB-type source composed of
