A 7.0-magnitude earthquake struck in seas off far northern Japan and far eastern Russiaon Friday, but no damage was expected. The Japan Meteorological Agency said sea changes were possible. No tsunami warnings have been issued.
The tremor struck around midday in the Pacific Ocean at a relatively shallow depth of 10km (6.2 miles). The US Geological Survey measured a stronger 7.2 magnitude. Japan and Russia both claim some of the sparsely populated islands in the remote region.
The epicentre was 58 kilometers (160 miles) east-northeast of Kuril'sk, Russia, and 528km (328 miles) northeast of Nemuro, Japan.
The nearest land is the volcanic islands of Urup, Iturup and Sumushir. Hokkaido officials said the islands were not under Japanese control.
The area is about 1,500km (930 miles) northeast of Tokyo.
