| Abstract | In geothermal field was tomogaphically using data. This study led to the of a anoinaly. located at a depth about 7 kin. presence of a deep body is in this paper by a inagnetotelluric investigation to determine the electrical of the This conclusion is based upon the expectation that a body rise to an increase in electrical conductivity. An MT survey was carried and recordings of the electromagnetic fields made at sites two and also at the distant site of Capraia Island. The use of a remote island as a ret'erence location allowed the of interference caused by a nearby electric railway. 4 technique was that simultaneously solved for the frequency train impedance and naturally occurring impedance. This separated the train effect from the natural UT signals. All the data were analyzed in this fashion and were used as input to inversion modelling. results of inversions were consistent with the results of seismic tomography and other data |
