3m high Tsunami predicted!
Revised to 6.9:
An earthquake with a preliminary magnitude of 7.3 hit northern Japan on Tuesday, the Japan Meteorological Agency said, generating a tsunami that hit the nation's northern Pacific coast.
The U.S. Geological Survey initially put Tuesday's quake at a magnitude of 7.3 but down graded it to 6.9.
The earthquake, which was felt in Tokyo, was centered off the coast of Fukushima prefecture at a depth of about 10 km (6 miles) and struck at 5:59 a.m. (2059 GMT) the agency said.
A 60 cm (2 foot) tsunami had been observed at Fukushima's Onahama Port and a 90 cm (3 foot) tsunami at Soma soon after, public broadcaster NHK said. The region is the same that was devastated by a tsunami following a massive earthquake in 2011.
A tsunami warning of up to 3 meters (10 feet) has been issued.
One woman suffered cuts to her head from falling dishes, Kyodo news agency reported, citing fire department officials.
