Japan’s meteorological agency said the quake was considered to be an aftershock from a magnitude-9.0 earthquake – the most powerful ever recorded in Japan – that struck almost 10 years earlier, and killed at least 15,000 people.
NHK reported minor damage and injuries in Fukushima prefecture, but said more than 800,000 people had been left without power.

The earthquake raised fears for the Fukushima Daiichi Nuclear Power Plant in Ōkuma, where major damage caused during the 2011 quake caused reactor meltdowns. However, the plant’s operator, TEPCO, said “no abnormalities” were found. Credit: Hiroki Suzuki via Storyful
