A powerful earthquake struck central Japan on Monday, triggering warnings for residents to evacuate some areas on its west coast, destroying buildings, knocking out power to thousands of homes and disrupting travel to the region.

The quake with a preliminary magnitude of 7.6 triggered waves of around 1m (3 feet) along parts of the Sea of Japan coast, with authorities saying larger waves could follow.

The Japan Meteorological Agency (JMA) issued tsunami warnings for the coastal 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.

Several houses have been destroyed and army units have been dispatched to help with rescue operations, top government spokesperson Yoshimasa Hayashi told reporters, adding that authorities were still assessing the extent of the damage.

More strong quakes in the area, where seismic activity has been simmering for more than three years, could occur over coming days, JMA official Toshihiro Shimoyama said.

In comments to the press shortly after the quake struck, Prime Minister Fumio Kishida also warned residents to prepare for more disasters.

“Residents need to stay on alert for further possible quakes and I urge people in areas where tsunamis are expected to evacuate as soon as possible,” Kishida said.
