Description:
We studied the broader area of Thessaloniki in northern Greece and Chalkidiki and
performed an InSAR campaign to study the surface deformation phenomena that have been known
to exist for at least two decades. Sentinel-1 data (2015–2019) together with drill measurements were
exploited to focus on specific sites of interest. Our results indicate an ongoing displacement field.
At the region of Kalochori and Sindos—where intense subsidence in the 1990s was previously found
to have had a natural surface rebound in the 2000s—a new period of subsidence, caused by the
enlivenment of the groundwater overexploitation, was reported. The uplifting trend of Oreokastro
is still active and subsidence in Anthemountas graben is ongoing; special focus was set on the
Makedonia Airport, where significant displacement is occurring. The study also reveals a new
area at Nea Moudania, that was not known previously to deform; another case corresponding to
anthropogenic-induced surface displacement. Thessaloniki is surrounded by di erent persistent
displacement phenomena, whose main driving mechanisms are anthropogenic. The sensitivity of the
surface displacements to the water trends is highlighted in parts of the study area. Results highlight
the plan of a water resources management as a high priority for the area.
