Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract We investigate the role of the elasticity and density of the forearc mantle wedge corner on the stress distribution in the forearc region of subduction zones, using numerical quasi‐2D lithospheric deformation models for the Cascadia, Nankai, NE Japan, and Costa Rica subduction zones. We incorporate the forearc mantle wedge corner as an elastic
