Japan: Tsunami warning for north-east after earthquake

A tsunami warning has been issued for north-eastern Japan after an earthquake with a magnitude of 7.4 struck off the east coast of Honshu.

The tsunami is predicted to have a wave 1m (3ft) high. Those in the warning zone should move to high ground, Japanese TV said.
The area was ravaged by an earthquake and tsunami last month which severely damaged the Fukushima nuclear plant.
Thursday's quake was 118km (78 miles) north of Fukushima, 40km offshore.
The Tokyo Electric Power Company (Tepco), which operates Fukushima, says it is checking on the situation at the damaged plant following the latest earthquake.
The quake was strong enough to shake buildings in Tokyo.
