  The Quaternary geodynamics of the Central Mediterranean region is controlled
by the migration of narrow orogenic belts within the slow Nubia-Eurasia plate
convergence. As testified by the occurrence of major volcanic and seismic
events, the Eastern Sicilian Margin is presently one of the most active
regions. Using a Permanent-Scatterer approach, we process Sentinel-1 satellite
images acquired from 2015 to 2020 to provide an island-wide quantification of
surface displacements at a high spatiotemporal resolution. We then convert the
calculated mean surface velocities along the ascending and descending satellite
line of sight into the ITRF2014 reference frame by using GNSS velocity data
derived from regional stations. The resulting pseudo-3D velocity field mainly
highlights a general uplift of about $1.5 \pm 0.5$ mm/yr of the
Nebrodi-Peloritani range and its differential motion with respect to mainland
Sicily along the Cefal\`u-Etna seismic zone. Permanent/Persistent-Scatterer
(PS) vertical velocities in the Eastern Hyblean region reveal a long wavelength
eastward down-bending of the margin, including the inferred epicentral area of
the 1693 Noto earthquake. Compared to Quaternary coastal uplift rates, these
results confirm the relative low activity of Western Sicily, a potential slow
uplift of South-Central Sicily and a significant discrepancy along the Eastern
Hyblean margin were PS-derived vertical velocities that appear 2-3 mm/yr lower
than the Quaternary rates. Over the 2015--2020 timespan, transient processes
are also captured, notably on Mount Etna, showing both magmatic pressurization
uplift and collapse of the eastern flank, but also all over Sicily where
numerous gravitational mass movements and anthropogenic ground subsidence are
detected.
