The arc extends about 2,100 km from Hokkaido, Japan, along the Kuril Islands
and the Pacific coast of the Kamchatka, Russia, peninsula to its intersection
with the Aleutian arc near the Commander Islands, Russia. It marks the region
where the Pacific plate subducts into the mantle beneath the Okhotsk
microplate, a part of the larger North America plate. This subduction is
responsible for the generation of the Kuril Islands chain and the deep
offshore Kuril-Kamchatka trench. Relative to a fixed North America plate, the
Pacific plate is moving northwest at a rate that decreases from 83 mm per
year at the arc's southern end to 75 mm per year near its northern edge.

震源深度达625km, 难怪到岩手县盛冈市都有三级的震度...
