Subduction System Response to Ribbon Collision: Implications on the Intra‐Plate Force Balance and the Style of Slab Deformation

by
Figure 3 from Rodriguez‐Corcho et al. (2026)

Using three-dimensional numerical models, the authors investigate how a buoyant ribbon of thickened oceanic crust colliding with a subduction zone disturbs stress and strain within the subducting slab and the surrounding plates. They find that the angle of collision creates compartmentalised zones of high and low strain rate around a region of strong vorticity, and … Read more…

5.8 magnitude Mansfield earthquake reflects compressive intraplate stress reactivating deep faults

by

Forces acting along the edges of tectonic plates, particularly compressive forces caused by plate convergence and orogeny, propagate into the interior of plates and cause deformation within continents. Forces acting on the edges of plates include compressive forces due to plate collisions and mountain building, so-called “ridge push” forces caused by the excess gravitational potential … Read more…
