A 6.9-magnitude earthquake shook northeastern Japan on Wednesday, though no major damage was reported, according to CNN.
The Japanese Meteorological Agency issued a brief tsunami advisory for a half-meter wave, which was called off a short while after the agency issued it. The quake hit 170 miles off the east coast of Japan. According to CNN, the police said there were no reports of damage.
The earthquake happened just three days after the first anniversary of the Tohoku earthquake and subsequent tsunami, which left 19,000 people dead or missing and triggered a nuclear crisis in Fukushima.
