Nea Kameni volcano movement captured by Envisat

Archived data from the Envisat satellite show that the volcanic island of Santorini has recently displayed signs of unrest. Even after the end of its mission, Envisat information continues to be exploited for the long-term monitoring of volcanoes. Santorini is a picturesque Greek island in the south Aegean Sea and the most active volcanic centre in the South Aegean Volcanic Arc. The island is the site of one of history's largest volcanic eruptions, about 3600 years ago. The geological record over the past million years reveals an extensive history of eruptions, with the most recent occurring in 1950. But despite being dormant for over half a century, satellites have detected slight movements. These and other findings were presented at the International Forum on Satellite Earth Observation for Geohazard Risk Management , currently under way in Santorini itself.
