From: High resolution seismic data coupled to Multibeam bathymetry of Stromboli island collected in the frame of the Stromboli geophysical experiment: implications with the marine geophysics and volcanology of the Aeolian Arc volcanic complex (Sicily, Southern Tyrrhenian sea, Italy)

Figure 5

Sketch diagram according to the geodynamic model of Malinverno and Ryan 1986 (modified after Malinverno and Ryan 1986). 1: the evolution of the arc-trench system (A) is related to the velocity of the slab retreatment (Vr) and to the dipping angle (θ). In a fixed reference system with respect to the subducting plate (B) the velocities which determinate the tectonic style are: vc (velocity of convergence among plates), v’r (velocity of retreatment of the overthrusting plate). When the convergence does not exist (vc = 0) it verifies extension in the overthrusting plate in order to balance the retreatment of the subduction (C); 2) development of a basin, reflected by the outwards arc migration. 1: continent; 2: continental margin; 3: oceanic sector; 4: active subduction zone; 5: subduction zone not still active. The stages A, B and C indicate the time evolution.
