Slab retreat dynamics

Sketch of three different ways to allow for fast subduction trench retreat that are flattening of the slab from side view (top left), curvature of the slab from top view for narrow (top centre) and wide subduction zones (bottom), and partial slab damage (i.e., slab window) from side view (top right). Shown are initial (grey) and end position (black) of the plate and corresponding mantle flow (blue) that displaces mantle material from its initial region (orange) to its final region (green).
