A strong and deep 6.7-magnitude earthquake struck off the coast of southwest Japan early Sunday, the US Geological Survey said. No tsunami warning was issued.
There were no immediate reports of injury or damage caused by the earthquake, which had am epicentre 132 kilometres (82 miles) northwest of Naze, Japan.
The quake was relatively deep at 164 kilometres and struck at 12:51 am local time (1551 GMT Saturday), according to USGS.
Japan’s Kyodo News agency reported that the earthquake was felt in Okinawa as well as the island of Kyushu.
Japan sits on the Pacific “Ring of Fire”, an arc of intense seismic activities that stretches through Southeast Asia and across the Pacific basin.
In 2011, a devastating 9.0-magnitude earthquake struck roughly 130 kilometres east of Miyagi prefecture, unleashing an enormous tsunami, triggering the Fukushima nuclear reactor meltdown and killing nearly 16,000 people.
