Brief comment: 
In some places the triangular facets are very well conserved and they seem very recent. Locally the Pliocene-Pleistocene sediments are vertical for the effect of the drag of the fault (Sanz de Galdeano et al., 2012).

Quaternary

Brief comment: 
From the displacement observed in the last 1 Ma. If the displacement of the last 5 Ma is considered, vertical slip rate is of the order of 0.16 m/ka. (Sanz de Galdeano et al., 2012).
