Plate convergence is a tectonic phenomenon in which two lithospheric plates move toward each other, driven primarily by mantle convection, slab pull, and ridge push forces. At convergent boundaries this motion produces either subduction, where denser oceanic lithosphere descends into the asthenosphere, or continental collision, where buoyant continental crust resists subduction and thickens to form orogenic belts. Plate convergence governs large-scale crustal deformation, metamorphism, magmatism, and the generation of volcanic arcs and accretionary prisms, and it is a primary control on seismicity, including megathrust earthquakes, through elastic strain accumulation and release along plate interface zones.
A chain of remote islands and underwater volcanoes between Alaska and Kamchatka has revealed a much older chapter in Earth's tectonic history than previously known. Along the Aleutian Arc, the Pacific Plate dives beneath ...
