A scientific team from the Hellenic Authority for Geological and Mineral Research (EAGME), consisting of Mr. M. Xenakis, Ms. E. Stefanou, and Mr. P. Trimis from the Department of Geothermal and Thermal Mineral Resources (GEOTHE), recently visited the island of Ikaria following an invitation from the Municipality of Ikaria and in collaboration with the DAFNI Network.
The purpose of the mission was to carry out extensive surface and subsurface temperature measurements across the island, aiming at an initial assessment of Ikaria’s geothermal status.
The measurements included temperature profiling of springs and wells, thermal imaging to detect known and unknown hot discharges, water sampling, and radon measurements.
From the collected data, as well as previous findings, it has been confirmed that along the coastal zone from Lefkada to Agia Kyriaki, temperatures of up to 59°C have been recorded in thermal discharges. These results are considered encouraging indicators for the identification of geothermal potential that could support various direct uses of geothermal energy.
However, to achieve this, targeted scientific investigations are required, such as geophysical surveys and specialized sampling. If subsequent studies confirm the geothermal interest, exploratory drilling could follow at selected sites to better determine the qualitative and quantitative characteristics of the geothermal potential available for utilization.
In the northern part of Ikaria, in the area of Avlaki, minor thermal anomalies of up to 28°C were also detected, which require further investigation to determine possible coastal and submarine thermal discharges.
The scientific fieldwork was carried out as part of the Subproject “Actions for the Rational and Sustainable Utilization of Geothermal Energy - GEOTHERM” under the Project “Studies and Research Supporting the Energy Sector of Industry and Entrepreneurship - OPYGEC,” implemented by the GEOTHE Department of EAGME and funded by the Operational Programme “Competitiveness, Entrepreneurship, Innovation” (EPAnEK).
