The Magnitude 6.0 temblor hit Fukushima Prefecture shortly after daybreak Wednesday, the meteorological agency said. No tsunami alert was issued. Tokyo Electric Power Co., which operates the troubled Fukushima Dai-ichi nuclear power plant, said it has received no reports of damage at the complex due to the quake.
On Tuesday, workers at the plant hooked up power lines to all six of the crippled complex's reactor units, but other repercussions from the massive earthquake and tsunami were still rippling across the nation.
