Sister Geopark: “Lesvos Island Geopark”

The San’in Kaigan Geopark and the Lesvos Island Geopark signed a sister-geopark agreement in February 2011.

The San'in Kaigan UNESCO Global Geopark is promoting the building of a network through sister tie-ups with the aim of developing and popularizing geopark activities in cooperation with geoparks around the world.

By forming the sister affiliation with the Lesvos Island UNESCO Global Geopark (Greece), cooperation activities are being conducted in exchanging information on the conservation and utilization of resources, and in introducing and promoting geoparks.

There are many hot springs on the Lesvos Island. This is because the groundwater, heated inside the earth, rises along the fault and springs up as a hot spring.

（３）"The Aegean Sea" was formed by spreading of the ocean

The Aegean Sea is a sea formed by the continent breaking with the movement of the plate. Along with this, the volcano has also moved to its current position.
