鄂霍次克海形成于中新世晚白垩世火山弧和边缘盆地的位置。中新世有两个火山弧：千岛群岛和萨哈林岛。在鄂霍次克海西部的库页岛弧下，有不少于200公里的洋壳被俯冲。鄂霍次克海的相当一部分，对应于科学院和海洋研究所的上升，在俯冲过程中下沉约1000米，其沉积盖层经历了折叠，一直持续到现在。与此同时，千岛弧后的千岛盆地也发生了张开。目前，鄂霍次克海是太平洋、北美、欧亚和阿穆尔四个岩石圈板块的交汇区。鄂霍次克海微板块位于它们之间，它与这些板块的相互作用产生了该地区目前的特征。
The Sea of Okhotsk was formed in Miocene time at the site of the Late Cretaceous volcanic arc and marginal basin of this region. Two volcanic arcs existed in the Miocene: the Kuril and the Sakhalin. No less than 200 km of oceanic crust have been subducted under the Sakhalin arc in the western part of the Sea of Okhotsk. Considerable parts of the Sea of Okhotsk, corresponding to the Academy of Science and Institute of Oceanology rises, subsided about 1000 m during the subduction process and their sedimentary cover experienced folding, which continues to the present time. At the same time there occurred the opening of the Kuril Basin behind the Kuril arc. At present, the Sea of Okhotsk is a region of the junction between four lithosphere plates: the Pacific, North American, Eurasian and Amurian. The Sea of Okhotsk microplate is located between them and its interaction with these plates has produced the present pattern of features in the region.
