The quake off the coast of Aomori and Hokkaido triggered tsunami warnings and evacuations amid fears of 3 metre waves.<\/b>
\nA powerful magnitude 7.6 earthquake shook Japan\u2019s northeast region late on Monday, prompting tsunami warnings and orders for residents to evacuate.
A tsunami as high as three metres (10 feet) could hit Japan\u2019s northeastern coast after an earthquake with an estimated magnitude of 7.6 occurred offshore at 11.15pm local time, the Japan Meteorological Agency (JMA) said.
Tsunami warnings were issued for the prefectures of Hokkaido, Aomori and Iwate, and a tsunami of 40 centimetres had been observed at Aomori\u2019s Mutsu Ogawara and Hokkaido\u2019s Urakawa ports before midnight, JMA said.
The epicentre of the quake was 80km (50 miles) off the coast of Aomori prefecture, at a depth of 50km (30 miles), the agency added.
Japan is one of the world\u2019s most earthquake-prone countries, with a tremor occurring at least every five minutes.
East Japan Railway suspended some train services in the area, which was also hit by the massive 9.0 magnitude quake in March 2011.<\/p>\n
