Figure 16. 3D Model of the lithosphere structure of the Sea of Okhotsk. Upper - the Okhotsk
Sea floor relief. Middle - Moho relief. Lower - relief of the asthenosphere. The
asthenosphere in the upper mantle of the Sea of Okhotsk is located at a depth of 50-70 km
and beneath the Northwestern Pacific Basin it is revealed at a depth of 100 km. Diapirs of
partial melting come off the asthenosphere, reaching a depth of 25-30 km beneath the Tatar
Strait Trough, Deryugin Basin and Kuril Basin and causing active tectonic regime manifested
in volcanic, seismic and hydrothermal activity. Red color in the asthenosphere shows area of
magma formation beneath the sedimentary basins.
