The latest satellite-based radar measurements of the surface of the island group seems to show that some inflation has affected the volcanic complex since the start of the seismic crisis about 10 days ago. Michalis Foumelis, associate professor at the Department of Geology of the Aristotle University of Thessaloniki, reported to a local newspaper that „for some time now we have detected some signs of change in the volcano compared to its previous state of calm.“
The findings are not yet very conclusive and the observed deformation is still relatively weak, but could mean that magma has intruded at shallower levels, raising thus the chance of a new (probably small) volcanic eruption in or near Santorini.
„We were waiting for the other IMPIS networks to confirm that there was something and in turn we contacted the competent authorities, informed them and everything that is now underway began“, Foumelis added.
