7.3 magnitude earthquake hits Fukushima prefecture, injures dozens, triggers blackouts
It shook buildings for some time after it hit, shortly after 11:00 p.m. (1400 GMT).
At least two dozen people were injured, according to reports from the Kyodo news agency.
Houses and offices in the capital Tokyo, hundreds of kilometres away, also swayed and shook. No tsunami warning had been issued, the meteorological agency said.
Some 950,000 households were initially without power, government spokesman Katsunobu Kato told a briefing carried on public broadcaster NHK. The blackouts appeared to be concentrated in northeast Japan, including Fukushima and neighbouring prefectures.
There were no irregularities at the Fukushima Daiichi and Daini nuclear power plants, or at the Kahiwazaki-Kariwa nuclear plant, owner Tokyo Electric Power Company Holdings said. ■
