Temporal evolution of subduction initiation in a global, 3-D spherical numerical experiment showing the cold plates as viscosity isosurfaces (grey) and mantle plumes as a temperature isosurface (red). Individual snapshots highlight the different phases of plume-induced subduction initiation characterised by (a) onset of hot mantle plumes, (b) local lithospheric thinning, (c-d) development of strong lithosphere-asthenosphere boundary topography through shallow horizontal mantle flow and an additional plume pulse, (e-f) plate failure and, finally, (g-h) buoyancy-driven subduction.
