Just off Japan Coast (past 24 hours ): A 7.3 (with 1 meter Tsunami), followed by a 6.2 and half dozen 5.0+ Earthquakes. Fukushima NPP temporarily evacuated. No evidence of significantly rising Radiation Levels. (Dec 7, 2012 – 9:45am Pacific Standard Time – Update)

TV News Report: 7.3 Quake Hits Japan, Small Tsunami, Reactor 4 Spent Fuel Pool Still Standing:

The quake was an aftershock of the 9.0 Quake of March 11, 2011 (= Part 1 of my ‘One Year Later’ 2-part overview of the quake, tsunami and ongoing nuclear disaster, full of info, videos, etc.)  

  • !–> A following report mentioned that the other nuclear reactor site, not Daiichi (I), but Daina (II), just to the north, showed an abnormality, (See Dec 7, 2012 Ex-SKF report, “Slight Rise in Pressure in #Fukushima II (Daini) Nuke Plant Reactor 1 Bldg After Dec 7 M7.3 Quake“, from which this quote: “TEPCO’s manager Masayuki Ono explained “It’s not very serious”, even though he acknowledged the company did not know the cause of the pressure rise.”  (If I may weigh in on that, Mr. Manager, when anything happens in a nuclear reactor or spent fuel pool and you don’t have the slightest clue why it’s happening, THAT all by itself is SERIOUS.)  Additional info about that has been compiled by Washington’s Blog, HERE.  (By the way, “Washington’s Blog” may not be the fastest to post, but when it’s significant, the site sure includes some of the most excellent resources shortly after.  They dig for facts and perspectives that add something of value, something I appreciate!).

Eureka, CA – Dec 7, 2012 (with the above updated in Dec 8)  I’m sipping coffee in an old masonry building downtown.  The entrance has a sign which clearly states:

This is an unreinforced masonry building.
You may not be safe inside or near an unreinforced masonry building
during an earthquake.’

I was asleep on the other side of the Pacific Ocean, but apparently a massive 7.3M (on the Richter Scale) Earthquake struck off the east coast of Japan at 0:18 minutes after midnight Pacific Standard Time (18:18 JPT, or 08:18 UCT – you can use the Time Zone Converter to find out it was in your location).
