MT as a tool for geothermal exploration : a case study from Southern Tuscany

In this paper we will present the results of a study focused on the acquisition, processing and modelling of magnetotelluric (MT) data for the geophysical characterization of two geothermal areas located in the Southern Tuscany. Issues related to the noise characterization of the areas, robust processing, and modelling of the data will be addressed, highlighting also the limitations of such method due to the high cultural EM noise level.
