Geophysicists Find Source Behind “Sudden” Tectonic Plate Movements

Geophysicists from Yale University reveal that the combination of crustal plugs with weakening causes abrupt slab detachment in a few million years, which can account for observed precipitous changes in plate tectonic motion and rapid continental uplift. Yale-led research may have solved one of the biggest mysteries in geology — namely, why do tectonic plates […]
