A 7.8-magnitude earthquake deep under the ocean off Japan’s southern coast shook buildings in Tokyo on Saturday but no casualties or significant injuries and damage were immediately reported.
No tsunami alert has been issued.
According to the U.S. Geological Survey, the epicenter of the quake was in the Ogasawara Islands, some 860 kilometres south of Tokyo. The depth of the tremor was some 680 kilometres below the ocean floor.
Tokyo Electric Power Co said there were no abnormalities at the crippled Fukushima nuclear power plant following the quake, Reuters reported.
A 9.0-magnitude quake triggered a tsunami in March 2011 that caused nuclear meltdowns at Fukushima and left nearly 20,000 people dead.
