A strong earthquake has struck off an island chain south of Tokyo, but officials say there is no danger of a tsunami.
Japan’s Meteorological Agency said the earthquake hit this evening and measured a preliminary magnitude of 6.9. It said it was located very deep, about 480 kilometres below the ocean’s surface. Deep earthquakes generally cause less damage.
The agency said it was centred west of the Ogasawara island chain in the Pacific Ocean about 1,000 kilometres south of Tokyo.
Some islands in the chain were shaken strongly by the quake, but it was hardly felt in Tokyo.
Japan sits along the Pacific “Ring of Fire,” the arc of seismic faults around the Pacific Ocean where earthquakes and volcanoes are common.
The epicentre of the quake, which struck at 2219 (AEST), was located near the Ogasawara.
