Citing the new temblor, the government issued a tsunami alert in the country, though it was removed shortly. Fukushima has been jolted mostly over the nuclear radiation leak after the biggest earthquake followed by a massive tsunami in the country in Mar 2011.
However, Tokyo Electric Power Co (TEPCO) sources confirmed that the aftershock caused no further damage to the already crippled Fukushima Daiichi nuclear plant. Cooling-down operations resumed after the fresh quake.
Thursday's quake has hit the north-east coast of Japan, the area that was devastated in the earthquake and subsequent tsunami in Mar 2011. However there has been no reports of any damage in the area or to the nuclear plant that has been crippled by the tsunami earlier.
Approximately 28,000 people died in the Mar 11 catastrophe. The Fukushima nuclear plant has been completely crippled and radiation levels are increasing with traces of it being found in food and air in the nearby regions.
