Japan Residents Urged To 'Run Away!' Over Tsunami Warning
Coastal residents in Japan have been ordered to flee to higher ground after a strong earthquake with preliminary magnitude of 7.3 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 a tsunami advisory for much of the rest of north-east Japan's Pacific coast.
Tsunamis of up to 90 centimetres were recorded about an hour after the 6 am (0800 AEDT) earthquake.

Fukushima prefecture is home to the nuclear power plant that was destroyed by a huge tsunami following an offshore earthquake in 2011.
The operator of the plant said there were no abnormalities observed at the plant, Japanese public broadcaster NHK said.
The US Geological Survey measured the magnitude at 6.9. The earthquake shook buildings in Tokyo, 240 kilometres.
The meteorological agency said the quake struck at a depth of 10 kilometres.
NHK has urged people to evacuate immediately, reminding them of the devastating 2011 quake that killed about 18,000 people.
There were no immediate reports of damage or injury.
