MAGNETOLLURGIC MEASUREMENTS ON MILOS, GREECE-GEOTHERMAL EXPLORATION IN AN ACTIVE VOLCANO-TECTONIC ENVIRONMENT.

Objective

A COMMON INTERPRETATION OF DATA OBTAINED FROM SEVERAL GROUPS PARTICIPATING ON THE "EC GEOPHYSICAL PROJECT MILOS" SHOULD LEAD TO AN ASSESSMENT OF THE GEOTHERMAL RESOURCES OF MILOS.
A series of geophysical research projects was carried out on Milos (Greece) to test and improve the various exploration techniques and strategies on the known geothermal reservoir of the island. 8 research teams from 4 countries (France, United Kingdom, Greece and the Federal Republic of Germany) executed field experiments in joint efforts between 1984 and 1988. Magnetotelluric (MT) methods, audio megnetotelluric (AMT) methods and active audio magnetotelluric (AAMT) methods, electric selfpotential methods and seismological methods were applied to achieve a better understanding of the correspondence of the internal structure and goemetry of the geothermal reservoir with the change of relevant physical parameters.

The experimental phase is over and some of the final reports are available. There is a very close relation between the observed field parameters and the seismic activity with the contours of the geothermal reservoir of Milos.

Following the Travale Testsite experiments (1979 to 1983), the Milos Testsite projects within the Commission's third research and development programme is the second venture of this type. The results are in press as Special Issue of GEOTHERMICS, Pergamon Press.
THE NATURAL SOURCE MAGNETOTELLURIC TECHNIQUE WILL BE USED ON THE ISLAND OF MILOS (GREECE) TO DETERMINE THE ELECTRICAL RESISTIVITY TO A DEPTH OF 3=5 KM. ABOUT 40 SOUDINGS WILL BE UNDERTAKEN ON A DENSE NETWORK OF STATIONS.
