Sakkas et al. (2014): The SE part of the Hellenic Volcanic Arc (HVA), including Kos, Yali and Nisyros islands, is geodynamically very active and of high tectonic unrest. The authors present ENVISAT InSAR data, which show LOS velocity field, with values ranging between -4 to +4 mm/yr, combined with small standard deviation velocity (<1.4 mm/yr) and acceleration (-0.5 to 1.5 mm/yr2) values reveal an almost linear type of ground deformation. The strongest subsidence is associated with local geothermal areas, as well as rural areas due to intense water pumping. Motions along the main faulting zones have also been clearly identified.
