Fig. 2 - The width of the cataclastic band and the sharpness of faults tend to decrease moving from strike-slip (SS), normal faults (NF) to thrust faults (TF). Above, three examples from the Mesozoic carbonate rocks of the Dolomites (northern Italy). Thrusts are generally associated to sharper, continuous faults with respect to normal and strike-slip faults, characterized by multiple and anastomosed faults. This structural variation could explain why the coseismic slip along thrust faults shows higher double couple.
