TOKYO, Feb 14 (NNN-NHK) – At least 30 people were injured, after an earthquake with a magnitude of 7.3 struck, off Fukushima Prefecture in north-eastern Japan, late last night.
The quake was preliminarily measured with a magnitude of 7.1 and was later revised up to 7.3, the Japan Meteorological Agency (JMA) said.
At least 30 people were injured in Miyagi and Fukushima prefectures, according to local authorities.
The temblor occurred at around 11:08 p.m. local time (1408 GMT), with its epicentre at a latitude of 37.7 degrees north, and a longitude of 141.8 degrees east, and at a depth of 60 km, according to the JMA.
So far no tsunami warning has been issued.
The quake logged Upper 6 in some parts of Fukushima Prefecture, on the Japanese seismic intensity scale, which peaks at 7.
Chief Cabinet Secretary, Katsunobu Kato, said, about 950,000 households were left without electricity following the strong earthquake.
The blackout affected 860,000 homes under the area, covered by Tokyo Electric Power Company Holdings Inc. and 90,000 homes, under Tohoku Electric Power Co., Kato said.
Following the quake, the Japanese government set up a task force at the prime minister’s office.
Japanese Prime Minister, Yoshihide Suga, instructed the government to quickly survey the damage, conduct rescue efforts, in areas necessary, and to relay information to the public, as soon as possible.
The quake was also felt in the capital Tokyo, where an intensity scale of 4 was logged, with many reporting that, their houses and furniture underwent strong shaking and some saying they felt dizzy.
Tokyo Electric Power Company said, it found no abnormalities with the reactors at the Fukushima Daiichi and Daini nuclear power plants.
Meanwhile, no abnormality was found at Japan Atomic Power Co.’s inactive Tokai No. 2 nuclear power plant, in the village of Tokai, in Ibaraki Prefecture, according to the operator.
The quake is believed to be an aftershock of the earthquake that triggered a massive tsunami in 2011, in the same area, said Kenji Satake, a professor at the University of Tokyo’s Earthquake Research Institute.
“The 2011 quake was an enormous one, with a magnitude of 9.0, it’s not surprising to have an aftershock of this scale 10 years later,” Satake said.
According to the professor, although the quake was relatively large in scale, with the focus off Fukushima Prefecture, it was unlikely to cause a tsunami, because it had a deep epicentre of about 55 km below the sea surface.– NNN-NHK
