Authorities in Ibaraki Prefecture on Thursday continued to assess the damage from a strong earthquake overnight that injured two people, disrupted public transportation and caused buildings to sway in Tokyo.
Ibaraki Prefecture is home to two nuclear power plants. No immediate problems were reported at the idled Tokai No. 2 nuclear power plant, Japan Atomic Power Co. said. Tokyo Electric Power Company Holdings Inc., which runs the meltdown-hit Fukushima No. 1 plant in neighboring Fukushima Prefecture, also reported no problems.
The Ibaraki Prefectural Government said the magnitude-6.3 quake shattered windows at a junior high school gymnasium in Takahagi, where the quake registered lower 6 on the Japanese earthquake intensity scale to 7. It also caused the ceiling of an inn to collapse. Although the prefectural government said no one was injured in either case, a man in his 60s was slightly injured by a falling object in the city.
