Okhotsk-Chukotka Volcanic Belt

Okhotsk-Chukotka Volcanic Belt

The Okhotsk-Chukotka Volcanic Belt (OCVB) is a Cretaceous volcanic belt in northeastern Eurasia. It is one of the largest subduction-zone related volcanic provinces in the world, stretching some 3200 km and comprising about 2 million km3 of volcanic and plutonic material. The volcanism within the volcanic belt was related to the subduction of the ancient Kula Plate, which moved in a northward direction about 55 million years ago.
