Tectonic Plates are the ground. They are large slabs of earth that float on top of the magma.
Japan is under three tectonic plates
The Pacific Plate is the largest tectonic plate and is covered entirely by the Pacific Ocean.
There were two tectonic plates involved: the Pacific plate and the plate under Northern Honshu (it is unknown which plate is under the island).
Its under the South American Plate
Tectonic
The tectonic plate under parts of Europe and Asia is a continental crustal plate.
The movement of one tectonic plate under another occurs at convergent boundaries. For example, at this boundary denser oceanic crust slides under the lighter continental crust.

The Kamchatka earthquake was on the Pacific plate.

Subduction is the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate.
A destructive plate boundary - a subduction zone.
