Tokyo - Japanese authorities have registered more than 80 aftershocks near the eastern country's Fukushima prefecture, after the recent powerful earthquake, local media reported on Wednesday.
On Tuesday, the Japan Meteorological Agency said a 7.3-magnitude earthquake has hit the eastern part of the country's coast near the province of Fukushima and issued a tsunami warning.
Soon after that the agency had updated the magnitude of the tremor to 7.4.
The tsunami warning was later lifted.
According to the NHK broadcaster, a total of 82 aftershocks had been registered in the region and meteorologists warned that they could continue during the next week.
Japan is a seismically active region. In March 2011, a 9.0-magnitude offshore earthquake triggered a 46-foot tsunami that hit Japan's Fukushima nuclear power plant, leading to the leakage of radioactive materials and the shutdown of the plant.
