Eight people reported injured after southwest Japan quake

Eight people were reported injured after a 6.3-magnitude earthquake struck off southwestern Japan, but there appeared to be no major damage or tsunami.

The epicentre of the quake, which hit at 11.14pm local time on Wednesday, was located between the islands of Kyushu and Shikoku, the US Geological Survey said.

Japan experiences around 1,500 quakes every year. The vast majority are mild and even larger quakes usually cause little damage.

Japan’s Nuclear Regulation Authority said the Ikata power plant in the area was operating as normal.

“No abnormalities have been detected at the Ikata power plant... and the operation is continuing,” it said.

Government spokesman Yoshimasa Hayashi confirmed there were no tsunami warnings or abnormalities reported at power plants and said authorities were investigating what other damage may have occurred.

There was no report of deaths directly caused by the quake but regional governments and media reported at least eight minor injuries yesterday.

Oita prefecture said two elderly people fell and suffered minor injuries, while local media reported that there were six other small injuries in the Ehime region.

Local television reported that public water pipes burst at a dozen points in Uwajima city.

In Ozu city in Ehime, at least one landslide blocked a road while falling rocks also blocked some roads in Uwajima city.

The late-evening quake shocked residents of the area.

“I was about to go to bed when I felt the rumbling and knew a quake was coming. Then I felt a kind of jolt that I’ve never experienced in my life,” a fisherman from the Ehime region told broadcaster NHK.

“I was a bit panicky,” he said, adding that some small objects fell over in his house, although there was no major damage.

Sitting on top of four major tectonic plates along the western edge of the Pacific’s “Ring of Fire”, Japan is one of the world’s most tectonically active countries.

Japan’s biggest quake on record was a massive 9.0-magnitude undersea jolt in March 2011 off its northeast coast, which triggered a tsunami that left around 18,500 people dead or missing.

The 2011 catastrophe also sent three reactors into meltdown at the Fukushima nuclear plant.

Despite stricter building guidelines, many structures, particularly outside major cities, are old and vulnerable.

This was brought home in the 7.5-magnitude quake on Jan 1 this year that hit the Noto Peninsula and killed more than 230 people, many of them when older buildings collapsed. — AFP
