AB The Iberian microcontinent and its connected oceanic crust are affected by deformations related to  the  Eurasian-African  plate  boundary.  Active  stress inversions from populations of moment tensor focal mechanisms have been performed around  and  inside  the Iberian peninsula,  using  a  total  of  213  moment  tensor  estimates.  Main results are: 1) The tensorial solutions show better consistency and lower misfits compared to those obtained previously from first P arrival focal mechanisms. 2) Along the Eurasia- Africa  western  boundary,  the  type  of  active  stresses  progressively  changes easternwards from triaxial extension  to uniaxial compression along the Terceira Ridge, the Gloria Fault zone and the Gulf of Cadiz. 3) In the Betics-Alboran-Rif zone, uniaxial extension predominates with Shmax N155ºE trending. 4) In N Algeria, uniaxial compression reappears. 5) The Iberian foreland is currently under strike-slip to uniaxial extension tensorial conditions.
