(a) Length of subduction vs. time, in Model 7. Slab break-off initiates after 130 s beneath northern Adria and is complete after 380 s. (b) rotation of Adria vs. time (black curve = average rotation of the plate; blue and red dotted curves = rotation of northern and southern Adria, respectively). (c) azimuth of the motion of northern Adria vs. time. (d) superficial motion path superimposed above the top view at the end of experiment (600s). Note that the motion of Adria shifts to the NW when the subduction is active, before slab break-off.
