agreement with the ~E-W extension previously identified within the Albanian orogen.<br />
Our results show that the 2009 mainshock ruptured a roughly 9 km normal fault at a<br />
depth of 6km, which strikes ~N194 ° E <strong>and</strong> dips with an angle of ~45 ° to the west. The<br />
slip of the mainshock was confined in a single patch of ~9 km × 6 km, the average slip<br />
was 5 cm <strong>and</strong> the peak slip was 18 cm.<br />

The slip model was incorporated in a forward modelling scheme to simulate the ground<br />
motion distribution in the near field. The shakeMap (Fig. 2) obtained from the<br />
distribution of Peak Ground Velocity at phantom stations depicts the mezoseismal area<br />
within the Dibra <strong>and</strong> Bulqiza districts in Albania, in accordance with macroseismic<br />
observations. The region of occurrence of the 2009 sequence together with the<br />
seismogenic region of the 1967 Dibra event, form a roughly NNE-SSW trending<br />
