A powerful earthquake has struck central Japan, destroying buildings, knocking out power to tens of thousands of homes and prompting residents in some coastal areas to flee to higher ground.
The quake with a preliminary magnitude of 7.6 triggered waves of about 1m (3 feet) along Japan’s west coast and neighbouring South Korea on Monday, with authorities saying larger waves could follow.
The Japan Meteorological Agency (JMA) issued tsunami warnings for the prefectures of Ishikawa, Niigata and Toyama. A major tsunami warning – the first since the March 2011 earthquake and tsunami that struck northeastern Japan – was initially issued for Ishikawa but later downgraded.
