A strong 7.0 magnitude earthquake hit off the shores of Japan's southern Pacific island Sunday morning.
The Meteorological Agency says the offshore quake Sunday struck about 230 miles below the sea surface. The agency said there was no danger of a tsunami. There were no immediate reports of damage or injuries.
Northeastern Japan was devastated by a massive earthquake and tsunami on March 11 that left nearly 20,000 people dead or missing. Japan, which lies along the Pacific "Ring of Fire," is one of the world's most seismically active countries.
Aftershocks are expected.
