摘要：

The sensitivity of transversal apparent resistivity to the changes in the electrical resistivity of elements of a two-dimensional (2D) geoelectrical structure is studied by numerical modeling. This sensitivity is found to have a series of specific features, due to which the monitoring of transversal apparent resistivity can serve as a helpful addition to the monitoring of longitudinal apparent resistivity to trace the dynamics of subsurface and shallow crustal elements of the medium. It is shown that the method previously suggested for the inversion of relative changes in apparent resistivity into relative changes in electrical resistivities of the elements of the geoelectrical structure is applicable to the transversal electrical resistivity.
