A 6.2-magnitude earthquake struck off a coast near Tokyo on Saturday, the Japan Meteorological Agency said, saying there were no fears of a tsunami.
Large buildings in the capital trembled and train service was temporarily halted when the quake struck at a depth of 50 kilometers at 7:03 p.m. (7:03 a.m. Argentine time) in Pacific waters off the Japanese prefecture of Chiba.
The United States Geological Survey also reported the earthquake, which it measured at the same magnitude, according to the AFP news agency.
The Japanese nuclear authority did not detect any anomaly in the region’s nuclear plants.
Just before Tokyo residents felt the tremor, Japan’s advanced earthquake detection system asked television stations to warn of a potentially strong quake.
“It was like being on a boat floating on the water, rocking from side to side that seemed to last for more than 30 seconds,” an NHK presenter said after the tremor.
In early May, a 6.3-magnitude earthquake struck the Ishikawa region (center), killing one person and injuring 49.
The country still remembers the magnitude 9.0 underwater earthquake that struck northeast Japan in March 2011, triggering a tsunami that left 18,000 people dead or missing.
The 2011 tsunami triggered the meltdown of three reactors at the Fukushima nuclear plant, causing Japan’s biggest disaster since World War II, and the most serious nuclear accident since Chernobyl.
