Tasas de deformación GPS en la cuenca del Bajo Segura (Cordillera Bética oriental)

We estimate the present deformation rates ofthe Bajo Segura Basin (NE end of the Eastern Betic shear zone), from the analysis of a GPS network with 11 sites. We analyze the data from four observation campaigns carried out between June 1999 and January 2013. We used the 6.2 version ofGIPSY-OASIS soft...

Descripción
Sumario:We estimate the present deformation rates ofthe Bajo Segura Basin (NE end of the Eastern Betic shear zone), from the analysis of a GPS network with 11 sites. We analyze the data from four observation campaigns carried out between June 1999 and January 2013. We used the 6.2 version ofGIPSY-OASIS software to process GPS data in Precise Point Positioning mode (PPP). It is observed a ~N-S shortening in the whole basin, higher in the south, along the Bajo Segura faultzone, with rates varying from West to East between 0.73 and 0.24 mm/yr. In the northern borderofthe basin, along the Crevillente fault zone, N-S deformation rates are lower. However, it is observed a left-lateral movement ofthis faultzone varying between 0.44 and 0.75 mm/yr in the E-W direction
