Only one continuous GPS receiver was working in Calabria fifteen years ago. It was, and still is, on the roof of the Istituto Tecnico per Geometri A. Righi of Reggio Calabria thanks to the pioneering initiative of Prof. Francesco Guarnaccia. Thereafter, INGV started to install a cGPS network at national level (RING) and today there are more than 40 cGPS working in Calabria, including the stations of the network maintained by the Regional Civil Protection and other initiatives carried out like those by the University of Calabria and the international geodetic consortium Unavco that complement the current picture of the geodetic infrastructure. Results are of great impact for the comprehension of the active tectonics of the Calabrian Arc, including some important hints of the strain accumulation and release on faults. In this contribution, I will resume the main results enhancing the aseismic deformation detected during the long seismic swarm on Pollino Range in 2011--2014, and the intriguing strain rate field derived from the GPS velocity field when compared to seismic deformation.
