New earthquake strikes 90 miles from Fukushima plant

Japan has been rattled by a strong aftershock and tsunami warning nearly a month after a devastating earthquake and tsunami flattened the north-eastern coast.

The US Geological Survey gave the preliminary magnitude as 7.4 and it struck off the eastern coast 60 miles from Sendai and 90 miles from the stricken Fukushima nuclear plant. It was about 215 miles from Tokyo.
