Powerful 7.3 Magnitude earthquake just hit offshore Japan and Japan issued a Tsunami warning. The USGS initially had the earthquake at 7.3 M but appears to have changed it to a 6.9 M while moving it closer to shore, presumably increasing nearshore tsunami risk. The USGS removed all reference to the 7.3 M earthquake before we could get a screenshot. Without time and coordinates it is impossible to know if there was a 7.3 M followed by a 6.9 M or if it is the same earthquake. Below is the screenshot showing the 7.3 M and Tsunami Warning from Japan Meteorological Agency. How could Fukushima Nuclear Power Stations evacuate the shore immediately?

Here are the USGS shake estimates showing that it apparently hit the Fukushima reactors as a VI (or is it VI 1/2?), as well as possibly impacting other nuclear power stations.

TOKYO (Reuters) – 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.
Not only are the Fukushima reactors and missing corium (melted nuclear fuel) potentially at risk, but the huge containers of radioactive water. Note small dots which are huge containers of radioactive water onsite.
