We present an up-to-date high resolution picture of the on- going crustal deformation field of Iberian region, based on an extensive combination of permanent and non-permanent GPS observations car- ried out since 1999. We detected appreciable deformation along the NW and SE margins of the Iberian Peninsula and along the Gibraltar arc, while on the inner parts of the peninsula, the crustal deformation occurs locally at rate < 15 nanostrain/year. Keywords: GPS, strain-rate, plate motion, Iberia. 1 Introduction The geodynamic setting of the Iberian Peninsula and the surrounding regions in the Mediterranean and the Atlantic is the result of the NW-SE directed convergent proc- ess between the Eurasian and African plates with simultaneous extension and forma- tion of young oceanic basins in a back-arc setting due to the rapid roll-back of narrow slabs of subducting oceanic lithosphere [1]. One of these basins, the Alboran Sea is enclosed on three sides by the westernmost Alpine fold-and-thrust belt, the Betic Mountains to the N and NW and the Rif to W, SW and S. These mountain belts and the basin, together form the Gibraltar Orogenic arc, straddling the present-day Eura- sia-Africa plate boundary (Fig. 1). The region is marked by the occurrence of shallow depth (h < 40 km; Fig. 1) earthquakes of moderate magnitude. Along the Algerian margin, seismicity occurs on regional-scale WSW-ENE-trended structures with prevailing thrust focal mechanism solutions. Along the orogenic Arc and the Alboran Sea, seismicity is distributed over a wide area and occurs also at intermediate depth. Intermediate depth seismicity is focused along a N-S trend across the Alboran Sea and dipping southward from crustal depths beneath the Western Betics to a depth of ~150 km beneath basin centre
