TOKYO: A 6.2-magnitude earthquake struck off Japan’s northeast coast early on Monday morning, the US Geological Survey (USGS) said. The agency said the quake struck at 2:32 am in the Pacific Ocean at a depth of 70 kilometers (44 miles) north east of Japan’s Hokkaido island, close to the disputed Russian-administered Kuril Islands. There were no immediate reports of damage. USGS had earlier given the quake a slightly higher 6.6 magnitude and a shallower 60 kilometer depth reading. The epicenter lay closest to Russian territory, 94 kilometers from the town of Kuril’isk. The nearest Japanese city, Nemuro was located 291 kilometers away from the epicenter. The Kuril islands are at the heart of a long running territorial dispute between Japan and Russia.
