A 6.1-magnitude earthquake struck off the coast of Japan early Thursday, according to the U.S. Geological Survey (USGS).
The agency's website said it hit about 176 miles southeast of the city of Kamaishi and more than 200 miles east of Fukushima.
The National Oceanic and Atmospheric Administration (NOAA) has not said whether the earthquake could trigger any tsunami activity.
In 2011, a massive earthquake and tsunami caused meltdowns at three reactors in the Fukushima nuclear plant.
This comes just a day after a powerful 7.1-magnitude earthquake rattled Mexico, killing hundreds.
