Abstract:

The Ventas de Zafarraya fault scarp (N 36° 57´ 700, W 4° 07´ 500) in southern Spain (Prov. of Granada) reflects recent activity along a major fault in the central Betics. Two major “open fractures” of 8 and 7 km length were described here after the destructing „Christmas event“ (25.12.1884) of Arenas del Rey in the Granada Basin. E-W striking active structures from El Chorro (Prov. of Málaga) to Ventas de Zafarraya, accompanied by NW-SE structures, e.g., along the NE flank of the Torcal massif are associated with the fault trace.
Two paleosols have been dated with the 14C-method (AMS), yielding ages of 2315 ± 30 years BP and 2940 ± 140 years BP, which bracket the seismic quiescence period of > 600 years of soil formation and accumulation. A careful and preliminary interpretation of the geological trench mapping and the dating results in the detection of three paleoseismic events.
The calculation of the rupture length suggests M = 6.5 for the 1884 earthquake.
