Abstract
New findings about the deep origin of the geothermal fields and volcanic centres of the North Evian Gulf area, Central Greece, were arisen by combining a three-dimensional traveltime inversion study of a microseismic dataset recorded of 37 portable stations together with a Curie depth point analysis based on aeromagnetic data. A possible magma chamber can be presumed by the detection of a low seismic velocity volume with high Poisson ratio values at depths below 8 km and the Curie point depth estimation at about 7-8 km depth as well. Besides, the analysis gave information about how the main large tectonic structures (NW-SE) and other important NE-SW faults can facilitate the hydrothermal flux of the local geothermal field.
