Fig. 2From: Thermal modeling of subduction zones with prescribed and evolving 2D and 3D slab geometriesSchematic diagram of the subduction zone geometry employed in the model when \(D=2\). The inset axis highlights the subdivision of the slab interface above the coupling depth \(d_c\). Extension to \(D=3\) can be envisaged as the extrusion of this geometry in the \(\hat{\varvec{y}}\) directionBack to article page
