UPDATE 10.16 CST
The Japan meteorological agency initially issued a tsunami warning for a wave of up to one metre, but that was later lifted.
The warning was issued for a coastal area already torn apart by last month’s tsunami, which is believed to have killed some 25,000 people and has sparked an ongoing crisis at a nuclear power plant.
Announcers on Japan’s public broadcaster NHK told coastal residents to run to higher ground and away from the shore. Residents along the northeast coast were being evacuated.
The U.S. Geological Survey said Thursday’s quake was a 7.1-magnitude and hit 40 kilometres under the water and off the coast of Miyagi prefecture. The quake that preceded last month’s tsunami was a 9.0-magnitude.
