Two strong quakes jolt northern Japan

The pro-nuclear camp is so certain the technology is safe they must sleep at ease at night and not notice this whole lotta shaking going on.

Apparently a magnitude 6 shake in the Fukushima region will be enough to bring down the nuclear-disaster-waiting-to-happen cooling tank in reactor 4. This is sailing pretty close to the wind.....

Another rude awakening here in Tohoku. Bounced me out of bed, but the wife and baby slept right through it.

Zichi would be able to give a better understanding of the situation in the cooling tank but when you a say a magnitude 6 do you mean a magnitude 6 on the seismic scale or a 6 on the Japanese scale as they are two, totally different things. If you're saying a 6 on the seismic scale, then what depth are you talking about and at what distance.

The problem with the word apparently is it's not actually apparent to anyone.

If the spent fuel rod tank on top of #4 collapses, then we will all be in serious trouble, Tamarama.

Sorry Zichi,

I meant that you would be the best person to comment on #4 as you are very up-to-date on those things. I know that if you say something about the current state of affairs at Dai Ichi then it’s almost certainly very accurate. And a heck of a lot accurate than apparently/some bloke in the pub/I overheard something...

So, in short, I was paying you a compliment, whilst simultaneously questioning the logic/accuracy of the previous post.

weird first one I felt this am was about 0630am...........

Over the last week I've downloaded some iPhone apps that inform you of earthquake details. I assume there are similar, if not the same apps for other phones, etc.

I'm understandably concerned. Sincerely hope another big earthquake does not happen.

makes you wonder if the underneath foundation of the island is slowly weakening itself......

Earthquakes are not a new thing in Japan...

you're behind dude, try to keep up

Not too weird amigos, last year we had a few major quakes, back in March of 2011, right?? So we are in the perfect time frame to have major after shocks of similar magnitudes or worse, just like down in New Zealand. The good people of Christchurch thought everything was cool, but 9 months later?? So, us here in the Higashi Nihon area should not let our guards down, hoping that we will not have major quakes ever again, aint gonna happen. Japan is part of the so called Ring of Fire, just like Alaska, California, Mexico, Peru, Chile, Indonesia, the Philippines etc..and as long as this planet is around, were gonna be a grooving and a shakin, so better to at least be prepared with clean drinking water, food etc..for at least 1 week for your self and family.

It's a little new to see so many quakes in the areas most affected previously on the same day, though. Three good-sizes ones in Sanriku Oki, the site of the big quake, a bunch in Fukushima and other places nearby will understandably make people a little nervous. Those areas haven't stopped shaking, but this many together is a little weird.

Usually major quakes have a magnitude lower quake the following year or so (christchurch had one just a bit after a year, indonesia one as well). We have yet to see anything in the 7.5 to 8.0 range in the same area, so perhaps the latent energy is going off in frequent smaller ones.

Actually, zichi called this one from another post. He saw pink clouds on Sunday evening. There was total cloud cover in Sendai. We(I) couldn't see the sunset up here.

BTW, small earthquakes are prelude for the "big" one. We're do for one, the Miyagi Oki. The last time was in 1978. It happens every +/- 30 years. Did you know that there are at least six fault lines in Miyagi?

I got my frozen steak ready and Country Ma'am cookies on standby.

I didn't make any comment on this post? Anyway, there's no likely possibility of the No4 spent fuel pool collapsing which has been reinforced with concrete and steel.

In total agreement with you - lots of work has been done on the pool support structure.

This report annex http://fukushima.ans.org/inc/Fukushima_Appendix_G.pdf gives the decay heat of the spent fuel pool at Unit 3 as a fourth of the Unit 4 pool, which is at least one good thing.

I don't know much, but I know I do not like nuclear power...

Why are they always so early in the morning? It's unsporting.
