The southern part of the Iberian peninsula is over a subduction zone that arises from the convergence of the Euroasian plate and African plate. This region is characterized by a complex seismotectonic pattern and moderate seismic activity (see [4]) associated with the convergence between these plates and the limits of this subduction zone are not well determined. In this work the location of the subduction zone between the African and Eurasian plates is studied. A method of classification of functional data is employed in order to determine the limits of this zone. The used data are provided by the SPINA network that consisting of GPS stations located in the southern region of the Iberian Peninsula and Northern Africa. The method of classification used in this work is based on similarity measures. Furthermore, in order to determine the optimal number of groups in each classification, Silhouette coefficient is employed and finally, the results obtained are compared to the experts’ opinion.
