There are two models which characterize a forearc basin formation and deformation and are dependent on sediment deposition and subsidence (see figure). The first model represents a forearc basin formed with little to no sediment supply. Conversely, the second model represents a basin with a healthy sediment supply. Basin depth depends on the supply of oceanic plate sediments, continentally derived clastic material and orthogonal convergence rates.<ref name="Fuller et al. 2006" /><ref name="Kearey et al. 2006" /> The accretionary flux (sediment supply in and out) also determines the rate at which the sedimentation wedges grow within the forearc.<ref name="Fuller et al. 2006" />

The age of the oceanic crust along with the convergent velocity controls the coupling across the converging interface of the continental and oceanic crust. The strength of this coupling controls the deformation associated with the event and can be seen in the forearc region deformation signatures.<ref name="Kearey et al. 2006" />
