Coastal residents in Japan were ordered to flee to higher ground on Tuesday after a strong earthquake with a magnitude of 7.4 struck off the coast of Fukushima prefecture.

The Japan Meteorological Agency issued a tsunami warning for waves of up to 3 metres in Fukushima and Miyagi prefecture, and a tsunami advisory for much of the rest of northeast Japan's Pacific coast. There were no immediate reports of damage or injury.

Tsunamis of 1.4 metres and 90 centimetres were reported in Sendai and Soma about an hour after the 6 am earthquake, and the tsunami warning area was widened later in the morning.
