Big quake rattles Tokyo, 17 injured

A strong 6.0-magnitude earthquake shook buildings in Tokyoearly Monday, lightly injuring 17 people, but officials stressed there was no risk of atsunami.Tokyo inhabitants -- set to enjoy a national holiday -- were woken shortly after dawnby the quake, which jolted the densely-built apartments and office blocks.Local media said 17 people injured themselves as they stumbled while trying to takecover, with a 74-year-old Tokyo woman dislocating her shoulder.Some objects fell from shelves and furniture wobbled, an AFP reporter saw.The epicentre of the quake -- which hit at 5:18 am (2018 GMT Sunday) -- was near IzuOshima island southwest of central Tokyo, the Japanese meteorological agency said.The US Geological Survey said the quake had a magnitude of 6.0, revised upwardsfrom 5.8, and struck at a depth of 155 kilometres (96 miles).It was the biggest tremblor felt in the Japanese capital since the 9.0-magnitudequake that hit northern Japan in March 2011, unleashing a killer tsunami andtriggering the Fukushima nuclear crisis.Japan Meteorological Agency said quakes of such depth do not usually cause manyaftershocks, but warned the public that moderate aftershocks are possible for thenext few days.A number of train lines were automatically stopped as the quake struck, but wererestarted again a short time later. The Nuclear Regulation Authority said regional nuclear facilities avoided damage,including the crippled Fukushima Daiichi plant.Three of the reactors at the plant went into meltdown after a huge 9.0-magnitudeearthquake sparked a massive tsunami in March 2011.The wave destroyed vast swathes of the coastline as it smashed into Japan's northeast, killing more than 18,000 people.Japan is situated at the meeting place of several of the Earth's tectonic plates andexperiences a number of relatively violent quakes every year.But strict building codes frequently mean that even powerful quakes that mightwreak havoc in other countries can pass without much damage.
