Brief comment:

Adopted from the Sierra de Almenara-Sierra de Hinojar segment. Striae measurements at La Escarihuela site (Roquero et al., 2019). Booth-Rea et al. (2004) provide evidence of major left-lateral component in a wide deformation (~12 km) and complex zone.

Brief comment:

45 km (onshore) to 60 km (onshore and offshore) is the total length of the segment. Note that 10 km is the max length of single faults included in the shear zone of the segment (10-15 width). García-Mayordomo (2005), p.185 and Table 3.12.

Basis for association :

Spatial correlation (weak)

Brief comment or references :

Additionaly, earthquakes hypocenters at dephts corresponding to the lower crust (h>13 km) in the area could be related to the Palomares Fault Zone, as this is a deep tectonic structure. García-Mayordomo, J. (2005), fig. 4.23, p.294 and 297.
