A 7.1 magnitude earthquake rattled Japan on Saturday, causing a landslide and leaving hundreds of thousands without power nationwide.

The quake struck Saturday night with its epicenter off the coast of Fukushima, about 135 miles north of Tokyo, according to the Japan Meteorological Agency.

It registered a strong 6, the second highest level on the seismic intensity scale, in which it is impossible for a person to remain standing or move without crawling, in the southern part of Miyagi and in the Nakadori central and Hamadori coastal regions of Fukushima, the agency said. In Tokyo, the quake registered a 4 on the scale.

In Fukushima and Miyagi prefectures, several residents were transported to hospitals, but there were no early reports of serious injuries.

At least 950,000 homes nationwide were without power by midnight, government spokesman Katsunobu Kato said at a news conference.

The quake comes less than a month before the 10th anniversary of the March 11, 2011, 9.0-magnitude earthquake that triggered a tsunami and meltdown at Fukushima Daiichi Nuclear Power Plant. The 2011 disasters killed nearly 16,000 people, and displaced hundreds of thousands. The operator of the now disabled Fuskushima nuclear power plant said no abnormalities were detected after Saturday’s quake.
