These plates are often grouped with an adjacent principal plate on a tectonic plate world map. For purposes of this list, a microplate is any plate with an area less than 1 million km 2 . Some models identify more minor plates within current orogens (events that lead to a large structural deformation of Earth's lithosphere ) like the Apulian ...
Around 23 million years ago, western Japan was a coastal region of the Eurasia continent. The subducting plates, being deeper than the Eurasian plate, pulled parts of Japan which become modern Chūgoku region and Kyushu eastward, opening the Sea of Japan (simultaneously with the Sea of Okhotsk) around 15-20 million years ago, with likely freshwater lake state before the sea has rushed in.

A map depicting the Japan Trench and its surrounding connections to other relevant trenches. The map was created using GeoMapApp. Topographic map of central Japan, showing location of trenches, tectonic plates and boundaries. The Japan Trench is an oceanic trench part of the Pacific Ring of Fire off northeast Japan.
Obduction zones occurs when the continental plate is pushed under the oceanic plate, but this is unusual as the relative densities of the tectonic plates favours subduction of the oceanic plate. This causes the oceanic plate to buckle and usually results in a new mid-ocean ridge forming and turning the obduction into subduction. [citation needed]
Japan has 111 active volcanoes. That is 10% of all active volcanoes in the world. Japan has stratovolcanoes near the subduction zones of the tectonic plates. During the 20th century, several new volcanoes emerged, including Shōwa-shinzan on Hokkaido and Myōjin-shō off the Bayonnaise Rocks in the Pacific. [18]
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
