A strong earthquake with a magnitude of 7.5 struck off the eastern Russian coast to the north of Japan, the US Geological Survey said on Tuesday, but no tsunami warning was issued by Japanese authorities. The quake was measured very deep at around 580 km (360 miles) below the earth's surface. Japanese television said the quake was measured at 7.3.

There were no immediate reports of damage or injuries. The quake hit the coast just before 1 p.m. local time on Tuesday. It was centered in the Pacific Ocean 100 miles east of Poronaysk, Russia, at a depth of more than 388 miles. In Japan, the Meteorological Agency reported that there was no risk of a tsunami from the quake. It said the quake was mildly felt on the northern Japanese island of Hokkaido and in the northeastern section of Honshu, Japan's main island.
