At least 30 people were injured after a magnitude 7.5 earthquake hit north-eastern Japan on Monday night, forcing thousands of people to evacuate their homes.
The quake occurred at 23:15 (14:15 GMT) at a depth of 50km (31mi), about 80km off the coast of the Aomori region, the Japan Meteorological Agency said. It prompted tsunami warnings which have now been lifted, while waves of 70cm (27in) were seen.
Some train services have been suspended and thousands of homes have been left without power as a result.
