An earthquake with a magnitude of 6.1 jolted Kuril Islands at 10:25:00 GMT on Sunday, the GFZ German Research Center for Geosciences said.
The epicenter, with a depth of 212.5 km, was initially determined to be at 48.80 degrees north latitude and 152.45 degrees east longitude.
The Kuril-Kamchatka Arc extends approximately 2,100 km from Hokkaido, Japan along the Kuril Islands and the Pacific coast of the Kamchatka Peninsula, until terminating at its intersection with the Aleutian arc south of the Commander Islands, Russia. It marks the region where the Pacific plate subducts into the mantle beneath the Okhotsk mircoplate, a proposed regional subdivision of the larger North America plate. This subduction is responsible for the generation of the Kuril Islands chain, volcanoes along the entire arc, and the deep Kuril-Kamchatka Trench. Relative to a fixed North America plate, the Pacific plate is moving northwest at a rate that increases from 79 mm/yr near the northern end of the arc to 83 mm/yr adjacent to Hokkaido.
