The expert system GEO 2.5 has been applied to the analysis of geophysical and geological data from Costa Pica.
Geophysical data consist of seismic tomography, Bouguer anomalies, seismic catalogue (RSN-ICE, 1984-1993) and seismic historical catalogue. Among the geological data, faults, lineaments, topography and a structural zonation of the region concerned have been used. Many other features have been obtained through the calculation of statistical functions of the original data such as nearness, density, length and b-value, other functions were secondary derivatives and modulus of horizontal gradient.

Abstract
Geophysical data consist of seismic tomography, Bouguer anomalies, seismic catalogue (RSN-ICE, 1984-1993) and seismic historical catalogue. Among the geological data, faults, lineaments, topography and a structural zonation of the region concerned have been used. Many other features have been obtained through the calculation of statistical functions of the original data such as nearness, density, length and b-value, other functions were secondary derivatives and modulus of horizontal gradient.File in questo prodotto:
