Shatsky Upland is an underwater elevation in the Pacific Ocean east of Japan . The base of the hill lies at a depth of 5500-6000 m, the summit surface is at a depth of 2400-300 m. The hill is elongated in a northeast direction. It consists of several arrays (Ori, Tamu, Shirshova). Its length is 1700 km, and the maximum width is 500 km [1] . Elevation studies were carried out by the courts of the USSR Academy of Sciences in the 1970s and 1980s. (" Dmitry Mendeleev ", etc.)
In 2013, it was established that the Tamu massif, located in the Shatsky Upland, is the largest volcano on Earth and one of the largest in the solar system [2] .
Presumably, the hill formed between the Late Jurassic and Early Cretaceous periods at the junction of three tectonic plates : Pacific , Farallon and Izanaga [3] . The hill is named after the Soviet geologist N. S. Shatsky [4] .
