The epicenter of the quake, which erupted at 11:07 p.m. local time (9:07 a.m. CET), was 73.9 kilometers northeast of Namie, a coastal city 60 miles from Fukushima, according to the United States Geological Survey.
The depth of the earthquake was about 36 miles. According to the state broadcaster NHK, injuries have been reported in Fukushima and Miyagi Prefecture. No tsunami warning was issued for the Saturday earthquake and no abnormalities were reported at the Fukushima nuclear power plant, according to Japanese Cabinet Secretary Katsunobu Kato.
On March 11, 2011, a 9.0 magnitude earthquake struck Japan. More than 20,000 people died or were missing in the quake and tsunami, while hundreds of thousands lost their homes.
The earthquake also caused the country’s worst nuclear disaster: three reactors at the Fukushima Daiichi nuclear power plant melted together, releasing radioactive material into the air. More than 100,000 people have been evacuated from the area.
Around 830,000 households in the Kanto region, which includes the greater Tokyo area, and around 90,000 households in the Tohoku region are without power after Saturday’s quake, Kato added.
Kato also said Prime Minister Yoshihide Suga had directed the government to investigate the damage caused by the quake, carry out rescue operations if necessary, and release information to the public in a timely manner.
In an earlier version of this story, the time of the earthquake was incorrectly stated. It happened at 11:07 p.m. local time.
