Pourquoi c'est important
Japan experiences frequent earthquakes due to its position on the Pacific Ring of Fire. The Sanriku Coast has a history of major seismic events and tsunamis, including the devastating 2011 Tohoku earthquake.
The epicentre of the quake, which had a depth of 10km (six miles), was off the Sanriku Coast, The Japan News reported. Japan's Meteorological Agency (JMA) issued a tsunami warning for Hokkaido, Aomori and Iwate prefectures, with waves as high as three metres (10 feet) expected. The quake measured an "upper 5" on Japan's seismic intensity scale of zero to 7, strong enough to make it difficult for people to move around. In many cases, unreinforced concrete-block walls collapse. The tremor was strong enough to shake large buildings as far as Tokyo, hundreds of kilometres away. Authorities advised that the waves were already approaching coastal areas, according to national broadcaster NHK.
