An earthquake with an estimated magnitude of 6.0 jolted central Tokyo on Monday morning — the strongest temblor to shake the capital since the Great East Japan Earthquake three years ago.
No major damage was reported, but the Fire and Disaster Management Agency said 16 people were injured in the Tokyo area.
The quake struck at 5:18 a.m. and measured lower 5 on the Japanese seismic intensity scale to 7 in the Otemachi business district in Chiyoda Ward, the Meteorological Agency said.
The magnitude of the quake was initially reported as 6.2.
The focus was 162 km below the seabed off Izu Oshima Island, the agency said. It did not trigger a tsunami.
The intensity was the strongest in Chiyoda since the upper 5 logged from the 9.0-magnitude quake that struck off the coast of Tohoku in March 2011.
Monday’s temblor along the Pacific plate likely has little to do with the major quake that experts predict will strike directly beneath Tokyo or in the Sagami Trough south of the capital, said Yohei Hasegawa, director of the Meteorological Agency’s Earthquake and Tsunami Observation Division.
Aftershocks generally do not follow a quake of this depth, Hasegawa said, but he urged people to prepare for the possibility of an aftershock of 3 or 4 on the Japanese scale.
Those injured in the quake included a 66-year-old woman in Kawasaki who collapsed and suffered a broken bone, local authorities said.
Four people were injured in Yokohama after they were struck by falling objects. Eight others were injured in Tokyo, one in Tokorozawa, Saitama Prefecture, and two in Ichikawa and Kisarazu, in Chiba Prefecture.
