Abstract
Abstract: A preliminary magnetotelluric study consisting of twenty measurements, in the frequency range 128–0.016 Hz, was undertaken on the active volcanic island of Nissyros. Two boreholes identify the existence of high enthalpy manifestations. The results correlate well with the borehole logs and delineate, in a 1-D approximation, the existence and symmetry of a possible geothermal reservoir. Some of the main faulting features were detected as well as an inferred highly conductive zone at the centre of the island.
