; ; ; ;Mauriello, P.; Istituto per le Tecnologie Applicate ai Beni Culturali, CNR, Roma, Italy ;Monna, D.; Istituto per le Tecnologie Applicate ai Beni Culturali, CNR, Roma, Italy ;Bruner, I.; Istituto per le Tecnologie Applicate ai Beni Culturali, CNR, Roma, Italy; ; In this paper we present the results of an alternating current resistivity survey, with a view to future tomographic processing. Two examples are given to evaluate the validity and the resolution of the method. The first in the Sabine Necropolis of Colle del Forno (Montelibretti, Rome), the second in the Etruscan settlement of Poggio Colla (Vicchio, Florence). All the measurements were carried out utilising current up to 512 Hz and a mobile dipole MN along straight lines, having two fixed current probes A and B. It was found that skin effect is uninfluential in the frequency range adopted. Given the absence of natural or artificial disturbances in the signal (e.g. electrode polarization and self potential), it was possible to perform very fast measurements with two operators only. Moreover, the use of a multiple dipole source configuration allows the calculation of the determinant of the apparent resistivity tensor. In the examples shown, this parameter detects the actual position of buried structures independently of the direction of the electric sources.205 221 - PublicationOpen AccessThe 1930 earthquake and the town of Senigallia (Central Italy): an approach to seismic risk evaluation(1995-11)

This city was almost completely destroyed by an earthquake of IX degree intensity on the Mercalli-Cancani-Sieberg scale (MCS) on October 30, 1930. This quake is the most recent and the best documented. In particular, this shock was characterized by strong differences in the damage levels at a scale of hundreds and tens of metres. The geographic position of Senigallia at the mouth of a river and its soil conditions, similar to many other coastal historical and tourist centres in the region, make this earthquake an important case history, useful for a better understanding of the seismic risk of the entire coastal area. This note reports the first results of a study on the possible causes of the different damage levels. The research started with the history and town-planning evolution of Senigallia, then. the regional or local geological characteristics were considered by geological, geotechnical and geophysical investigations.254 816 - PublicationOpen AccessExamples of application of tensorial resistivity probability tomography to architectonic and archaeological targets(2002)

The 3D tomographic approach, based on the concept of resistivity anomaly source occurrence probability, has been used for the analysis of the invariant parameter related to the trace of the determinant of the apparent resistivity tensor.148 280
