Topo-Iberia GPS network: results obtained at UJA Analysis Centre

Abstract

The project ”Geosciences in Iberia: Integrated studies of topography and 4-D evolution Topo-Iberia” (Ref.CSD2006-00041) is supported by the Spanish Ministry for the Economy and Competitiveness. Its objective is to understand the interactions in the Iberian Peninsula (SW Europe) between deep, shallow and atmospheric processes, through a multidisciplinary approach linking Geology, geophysics and Geodesy. As part of this project a network of 26 CGPS (continuous GPS) stations, covering the Spanish part of the Iberian Peninsula (22 stations) and Morocco (4 stations) was established in 2008 to complement other GPS networks already deployed by different Institutions, EPN (EUREF Permanent Network), IGS (InternationalGNSS Service) and regional governmental agencies to monitor crustal deformation due to Nubia and Eurasian tectonic plates. Data analysis is performed at three different analysis centres: Real Instituto y Observatorio de la Armada (ROA), University of Barcelona (UB) and University of Jaen (UJA). The coordinate time series and the velocity field from 2008-2013 computed at UJA analysis centre are presented in this paper. The estimated velocities show the southeast of the Iberian Peninsula is a boundary area between two plates accommodating the relative movements between the Eurasian and Nubia plates.
