Brief comment: 
This fault has associated abundant seismicity, particularly low magnitude earthquakes. The scarp is well conserved (Sanz de Galdeano et al., 2012).

Brief comment: 
Some striae indicate a dextral horizontal strike but it is not possible to know it importance. In any case the throw is the principal feature (Sanz de Galdeano et al., 2012).
