Residents in northeastern Japan were shaken after a powerful earthquake struck the region late Wednesday, serving as a poignant reminder of the mega-quake that brought death and widespread devastation to the Tohoku region just over 11 years earlier.

Tsunami warnings rang out Wednesday night in Miyagi and Fukushima prefectures, which were both devastated by the March 11, 2011, quake and tsunami. People were then forced to flee to the safety of higher ground as tsunami surges caused destruction along the coast.

On Wednesday night, buildings were damaged as walls and ceilings were shaken, while millions of homes, including some in parts of Tokyo, were left without power as local authorities scrambled to grasp the extent of the damage.
