WebNov 1, 2024 · Trench-parallel subduction of mid-ocean ridges occurs frequently in plate motion history, such as along the western boundary of the Pacific plate in the early Cenozoic and along the eastern boundary of the Pacific plate at present. Such subduction may strongly alter the surface topography, volcanic activity and slab morphology in the mantle, … Web[1] We present the results of an onshore–offshore wide-angle refraction and reflection experiment off Miyagi, in the central Japan Trench forearc region. There are two rupture zones of large interplate earthquakes here: the landward rupture zone and the trenchward rupture zone.

WebMost seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. ... This is called subduction. Subduction causes deep ocean trenches to form, such as the one along the west coast of South America. The rocks pulled down under the continent begin to melt. Sometimes the molten rock rises to the surface, ...
