A seismic network of more than 20 broad band stations and two arrays of 10 short period stations each, all working in local acquisition mode, are used to improve the seismic monitoring of Campi Flegrei and Vesuvius for research purposes. Data provided by ... see more

The Campi Flegrei caldera is an active volcanic system associated to a high volcanic risk, and represents a well known and peculiar example of ground deformations (bradyseism), characterized by intense uplift periods, followed by subsidence phases with so... see more

Employing 3D finite element method, we develop an algorithm to calculate gravity changesdue to pressurized sources of any shape in elastic and inelastic heterogeneous media. Weconsider different source models, such as sphere, spheroid and sill, dilating i... see more

The scaling law of the seismic spectrum experimentally calculated at Mt. Vesuvius and Campi Flegrei is used to constrain the estimate of the maximum expected peak acceleration of ground motion.

This paper describes the characteristics of the seismicity in the volcanic Neapolitan area during the year 2000 recorded by the monitoring seismic network of the Osservatorio Vesuviano. In particular, a detailed analysis of the seismicity of Vesuvius is p... see more

The results of an analysis of Dipolar Geoelectrical (DG), Magnetotelluric (MT) and Self-Potential (SP) datacollected over the emerged portion of the Campi Flegrei (CF) caldera (South Italy) are presented. The DG andMT data are from previous surveys, while... see more

The volcanic activity of Campi Flegrei and Ischia ranges between 150 ka and the present. The last eruption at Ischia occurred in 1302 CE, and that in Campi Flegrei in 1538. Eruptions at Ischia were more frequent during Greek and Roman times, whereas Campi... see more

The emergency planning of areas subjected to volcanic risk requires the evaluation of impact induced on different element exposed (people, buildings, infrastructures, economy, etc.) by different volcanic phenomena (precursor earthquakes, ash fall, pyrocla... see more

Employing a 3D finite element method, we develop an algorithm to calculate gravity changes due to pressurizedsources of any shape in elastic and inelastic heterogeneous media. We consider different source models, such assphere, spheroid and sill, dilating... see more
