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.

Ankō Outcrop in the village of Ōshika in Nagano Prefecture is a natural monument of Japan. Japan Median Tectonic Line (中央構造線, Chūō Kōzō Sen), also Median Tectonic Line (MTL), is Japan's longest fault system. [3] [4] The MTL begins near Ibaraki Prefecture, where it connects with the Itoigawa-Shizuoka Tectonic Line (ISTL) and the ...
Boso triple junction . The Boso triple junction (also known as off-Boso triple junction) is a triple junction off the coast of Japan; it is one of two known examples of a trench-trench-trench triple junction on the Earth (the other being the Banda Sea triple junction).
Scientists have known that the collision of the two tectonic plates, which began roughly 60 million years ago, caused the edge of the Eurasian plate to buckle, bulging and twisting into what we ...
The area is associated with large earthquakes in 1662 (M w 7.9), 1941 (M w 8.0), 1961 (M w 7.5), [3] 1968 (M w 7.5) and two in 1996 (M w 6.6 [4] and 6.7 [5]). The Hyūga Sea is interpreted as a transition zone between the highly coupled Nankai Trough in the northeast and weakly coupled Ryukyu Trench further southwest. [ 6 ]
Indo-Australian plate – Major tectonic plate formed by the fusion of the Indian and Australian plates (sometimes considered to be two separate tectonic plates) – 58,900,000 km 2 (22,700,000 sq mi) Australian plate – Major tectonic plate separated from Indo-Australian plate about 3 million years ago – 47,000,000 km 2 (18,000,000 sq mi)
In this area, the Okhotsk Plate is converging to the west-northwest towards the Amur Plate with a velocity of about 9 mm/yr and a maximum convergence rate of 24 mm/yr. [8] The Amur and Okhotsk plates are relatively small plates that are located between the Pacific plate and the Eurasian plate. The Pacific plate converges west-northwest towards ...
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]
