A powerful earthquake has struck off Japan's north-eastern coast, shaking buildings in Tokyo and forcing people out of their homes, witnesses said. Japan issued its most serious tsunami warning, saying a wave as high as 6m (20ft) could strike the coast near Miyagi prefecture. US officials said the 8.8-magnitude quake struck about 250 miles (400km) from Tokyo at a depth of 20 miles. TV pictures showed a wave crashing into the Pacific coast. The surge of water carried cars and ships as it surged through a coastal town.
