oday’s quake hit about 47km off the shore of Iwate prefecture at 6:51am (local time), the Japan Meteorological Agency said. Much of the coast in the area is still heavily damaged from March’s disasters. The US Pacific Tsunami warning centre said it did not expect a destructive Pacific-wide tsunami. The quake, 32km deep, caused tremors across the northern half of the country, including Tokyo, which is about 524km to the southwest. It was followed by several smaller aftershocks, according to the Japan Meteorological Agency. Japan is located on the Ring of Fire, an arc of volcanoes and fault lines spanning the Pacific Basin, and is regularly hit by earthquakes.
