Mar 20 (NHK) - A magnitude 6.9 earthquake hit northeastern Japan on Saturday evening. Officials in Miyagi Prefecture say some people are injured. A tsunami advisory was issued for the prefecture, but it was lifted after about an hour and a half.
The Meteorological Agency is warning that further jolts as strong as the initial one could occur over the next week or so.
The quake registered an intensity of 5-plus on the Japanese seismic scale of zero to 7 in parts of Miyagi Prefecture.
Some municipalities in the Tohoku region have opened evacuation centers. Some people moved to higher ground.
No abnormalities have been reported at nuclear power plants in the Tohoku region, including the Fukushima Daiichi plant.
The Meteorological Agency believes this was an aftershock from the massive quake that hit the region in 2011.
