A strong earthquake with a magnitude of 7.5 struck off the eastern Russian coast to the north of Japan.

A strong earthquake with a magnitude of 7.5 struck off the eastern Russian coast to the north of Japan, the U.S. 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, Reuters news agency reported.

Japan's Meteorological agency said the tremor was felt throughout the country's northern island of Hokkaido, but the Pacific Tsunami Warning Center said in a first and final bulletin that a destructive tsunami was not expected.

The earthquake caused a jolt in the Japanese capital Tokyo, AFP journalists said. The area around Japan is regularly hit by powerful quakes and is the site of the convergence of several of the Earth's tectonic plates.
