“…It has been applied for investigating areas of complex geology, such as volcanic and geothermal areas (Di Maio et al, 1998), seismotectonic structures (Caputo et al, 2003;Nguyen et al, 2005), and areas affected by hydrogeologic phenomena and environmental problems (Ogilvy et al, 1999;Lapenna et al, 2005;Soupios et al, 2007;Georgaki et al, 2007;Naudet et al, 2008). It has been also used to locate cavities in the subsoil (El-Qady et al, 2005;Gibson et al, 2007;Crawford et al, 2007;Mitrofan et al, 2008;Soupios et al, 2008).…”

Abstract. This work, carried out with an integrated methodological approach, focuses on the use of near surface geophysics techniques, such as ground penetrating radar and electrical resistivity tomography (ERT), and geomorphological analysis, in order to reconstruct the cave distribution and geometry in a urban context and, in particular, in historical centres. The interaction during recent centuries between human activity (caves excavation, birth and growth of an urban area) and the characters of the natural environment were the reasons of a progressive increase in hazard and vulnerability levels of several sites. The reconstruction of a detailed cave map distribution is the first step to define the anthropic and geomorphological hazard in urban areas, fundamental basis for planning and assessing the risk.

“…Since the kernel s(r) is a known function, we can compute the SPOP value at each node, using a discretised form of the integral in Eq. (5). A positive SPOP value gives the probability with which a positive pole, placed where the SPOP value is computed, can be considered as responsible of the A(r) field, while a negative value gives the probability for a negative pole.…”

Abstract-The 3D probability tomography theory is developed to image polar and dipolar sources of a geophysical field dataset. The purpose of the method is to improve resolution power of buried geophysical targets, using probability as a suitable paradigm allowing all possible equivalent solutions to be included within a single 3D image. The new approach is described by assuming a geophysical field dataset as caused by a discrete number of source poles and dipoles. A few tests are given to show how the combined polar and dipolar tomography can provide a reliable core-and-boundary resolution of the most probable sources of anomalies. An application to the Vesuvius volcano (Naples, Italy) is finally illustrated by analyzing self-potential and geoelectrical datasets collected within the whole volcanic area. A gravity dataset is also analyzed for completeness. The purpose is to get new insights into the Vesuvius shallow structure and hydrothermal system and to outline the features of the deep tectonic depression within which the volcano grew.

“…Further 3-D models, includ ing topography effects, should lead to a more detailed image of the resistivity distribution of Vesuvius. Since the beginning of the 1990s geoelectric techniques such as DC and magnetotellutrics (MT) have been used on Vesu vius [Di Maio et al, 1998]. Both methods show a conductive layer from shallow (1 km) to medium (5 km) depths below the volcanic edifice.…”

“…In further modeling, we plan to integrate the magnetotelluric data from Di Maio et al [1998] and our LOTEM data to obtain a broader depth range for the resistivity distribu tion. Such a joint inversion combines the ad vantages of high MT penetration depth with the high data quality at shallow and medium depths of LOTEM.…”

A newly refined electromagnetic technique has imaged the electrical structure of Vesuvius, and its success indicates it can be a very effective tool in forecasting volcano eruptions. The hope is to be able to gather enough data from active volcanoes to establish an adequate baseline of information for volcano surveillance and to better understand their structure. Known as the long‐offset transient electromagnetic (LOTEM) technique, its development has been made possible by modern modeling algorithms and higher computing power, both lacking in earlier electromagnetic work in the 1970s and 1980s. Such advances allow for analysis of complex topographic and three‐dimensional (3‐D) structures of volcanoes [A. Hördt and M. Müller, unpublished manuscript, 1999].
