Northeast coast off Fukushima

Earthquake jolts Japan's northeast coast

There were some reports of fire, the government said, and a number of people sustained injuries, but none of those immediately appeared serious. Public broadcaster NHK said one person had died.

The quake on Wednesday was felt in Tokyo, some 275km away, where the shaking of buildings was long and pronounced. Hundreds of thousands of homes in the capital were plunged into darkness for an hour or more, although power was fully restored by the early hours of Thursday morning.
