A strong earthquake with a preliminary magnitude of 5.6 shook northern Japan on Sunday, but there were no reports of damage or injuries.
The quake occurred shortly after 4 p.m. and was centered about 30 miles under the ocean floor off Iwate state, about 310 miles north of Tokyo, the Meteorological Agency said.
The heaviest perceivable shaking occurred along the region’s coastline. There were no reports of damage or injuries and no risk of tsunami, local police official Norichika Sasaki said.
An earthquake of magnitude 5 or higher can damage buildings when centered near heavily populated areas.
Japan is one of the world’s most earthquake-prone countries as it sits atop four tectonic plates, slabs of land that move across the earth’s surface.
