A magnitude 6.3 earthquake was reported in Japan on Tuesday. The tremors were strong enough to shake some of the buildings in Tokyo.
The quake hit at the depth of 33 kilometers off the coast of Honshu Island, said US Geological Survey.
Neither Japanese nor US authorities didn’t issue a tsunami warning.
No damage or injury from Tuesday's tremor has been reported so far.
Tokyo Electric Power Co says no abnormalities at its nuclear plants in Fukushima have been registered. The facilities, which were severely damaged just a year ago by a magnitude 9 quake and the massive tsunami that followed, became an epicenter of one of the worst nuclear crises in global modern history.
Since that disaster, which took some 20,000 lives in Japan, there has been a five-fold increase in earthquakes in the Tokyo metropolitan area, says the Tokyo University Earthquake Research Institute as reported by Reuters.
