Tsunami warning issued, then lifted after 6.9 earthquake in Japan

A tsunami warning was issued in Fukushima Prefecture in Japan after a massive earthquake Tuesday morning. It was later lifted, without any reports of damage or injuries.

But before the warning was lifted, a tsunami wave 3-10 feet high was expected to hit the coast.

A tsunami wave was spotted 22 kilometers off the coast of Iwaki City in Fukushima Prefecture, CNN affiliate NHK reported.

There was no tsunami danger for the U.S. West Coast after the earthquake.

The magnitude was initially reported at 7.3, but the USGS later downgraded the strength to 6.9. Two aftershocks were reported by USGS, one 5.4 and one 4.8.

News reports from Japan said buildings in Tokyo shook from the earthquake.

"Please do not think that you are safe. Please evacuate to high grounds," the network said. "Even if you live inland please go and evacuate."

All residents along the coast and in low-lying areas are urged to evacuate to higher ground.

Fukushima was the site of the Daiichi nuclear disaster in 2011. Authorities immediately took the nuclear power plants offline.
