Hot Springs of Loutropolis Thermi

The thermal springs of Loutropolis Thermi have been used since ancient times for curative purposes. At a temperature of 49,9οC, the ferrous hot spring water is very salty due to seawater mixing with hydrothermal water.

The existence of these hot springs is the result of the intersection of two deep faults with WNW – ESE and NNW – SSE orientations which facilitate water moving upwards from great depths. A mixture of rainwater and seawater percolates down into the crust, where it is enriched with minerals and heated. Then it moves up once again through cracks to more shallow depths or up to the surface where it is mixed again.
