Lateral slip rate of Alhama de Murcia fault (SE Iberiam Peninsula) based on a morphotectonic analysis: comparison with paleoseismological data

To define the seismic potential of the left-lateral strike-slip Alhama de Murcia fault (SE Iberian Peninsula), we calculated its slip rate by measuring offset linear features of known age using a morphotectonic analysis. The Lorca-Totana section of the fault yielded a minimum slip rate of 1.0 ± 0.2...
