The weight of the uplifted ocean ridge creates a downward force on the oceanic plate, causing it to be pushed towards a subduction zone. As the plate moves, it eventually descends into the mantle at the subduction zone due to gravitational forces, leading to the formation of a deep ocean trench.
Fukushima is located near a subduction zone, specifically where the Pacific Plate is subducting beneath the North American Plate. This geological setting is responsible for significant seismic activity in the region, including earthquakes and tsunamis. The proximity to the ocean also means that the effects of such geological events can be amplified by the surrounding waters.
Subduction Zone
Moun Cleveland formed as a result of a subduction zone, but is not a subduction zone in and of itself. A subduction zone is a feature that forms volcanoes, not a kind of volcano.
This process occurs at subduction zones, where one tectonic plate descends beneath another plate into the asthenosphere. Subduction zones are typically associated with deep ocean trenches and volcanic arcs.

Ridge push is a gravitation force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone.
A subduction zone forms when one oceanic plate is forced beneath another plate. This process can lead to the formation of volcanic arcs, deep ocean trenches, and seismic activity.

A subduction zone occurs at convergent plate margins where an oceanic plate is going underneath a continental plate or a less dense oceanic plate. A mid-ocean ridge is a divergent plate boundary on the ocean floor with a mountain range and a rift running through the center of it. Sea floor spreading also occurs at mid ocean ridges.
Deep ocean trenches and volcanic arcs form on the ocean floors in a subduction zone. The oceanic plate is forced beneath the continental plate, creating a deep trench. Melting of the subducted plate leads to the formation of magma, which can erupt at the surface to create volcanic arcs.

This is called the subduction zone.
Ridge push is a geological concept where the force of gravity causes oceanic lithosphere to move downhill from a mid-ocean ridge, pushing tectonic plates away from the ridge. This process contributes to plate motion along with other forces like slab pull and mantle convection.
The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.
