A tsunami warning, with the threat of waves of up to 3 meters, was issued Monday evening for Iwate Prefecture, Aomori Prefecture and Hokkaido in northern Japan after a quake struck off the coast of Iwate.

An NHK anchor urged local residents to move to higher ground, away from rivers and coastlines, calling on people to “remember the 3/11 disaster.”

“Tsunami! Evacuate!” flashed on NHK in English for viewers who don’t speak Japanese. “Don’t turn back.”

The quake, which struck at a depth of 10 kilometres at 4:53 pm, registered a 7.4 magnitude, according to the Japan Meteorological Agency.

Shaking was felt as far away as Tokyo, where buildings swayed for several minutes. (Japan Times)
