From: Evidence for a developing plate boundary in the western Mediterranean
Tectonic structures, seismicity and GPS velocities in the region. Active tectonic structures are shown in red (modified after ref. 16), and the currently inactive tectonic structures related to the Miocene subduction process are shown in white (modified after ref. 6). The location of the crustal earthquakes (<30 km) that have occurred in this area since 1916 to today is shown (see legend for details, data from IGN catalogue, http://www.ign.es/). The GNSS velocities in a fixed Eurasian reference frame are shown by the green arrows, together with the ellipses for 95% confidence11. The regional convergence value determined from GPS measurements is shown by the white arrows8. Inset: Location and crustal domains of the study area (cont.: continental). AIFS: Al-Idrissi Fault System, ARFS: Alboran Ridge Fault System, CFS: Carboneras Fault System, FP: Francesc Pagès Bank, NFS: Nekor Fault System, TB: Tofiño Bank, YFS: Yusuf Fault System.
