Japan: Powerful earthquake hits north-east

A powerful earthquake has hit north-east Japan, exactly a month after the devastating earthquake and tsunami.

The 7.1-magnitude tremor triggered a tsunami warning, and forced the evacuation of workers from the crippled Fukushima nuclear plant.

The epicentre of the quake was in Fukushima prefecture, and struck at a depth of just 10km (six miles).

The BBC's Roland Buerk in Otsuchi said that despite being far from the epicentre he too felt the quake.
