I'm not so sure. They were definitely taken before 2014, as there are no plumes of steam, but in the first picture below you can see what looks like a 'lot' of twisted steel girders, and in the second, the wall towards the top of the picture looks like it's 'leaning inwards', although the steel girders look intact, apart from next to where the wall appears to be leaning inwards. Could these be the two that the roofs 'blew off'?
Also, where the 'jib' of the red and white crane is in the first picture could be directly over the 'spent fuel storage tank', which is situsted on the top floor, and which they have been trying to lift the 'spent fuel rods', along with 'unused MOX fuel' from?
I'd need to re-read the earlier thread to be sure, I think. Then again, I could be completely mistaken, although I don't think 'construction work' is underway, as the girders in the first picture look far to twisted, etc.
EDIT: Also, if you look closely at other areas of the site on 'google maps' you can see '2013 GOOGLE' in various places in the images. I'll try to post a pic.
(Magnified 400%)
I'm not sure how reliable this is, but I believe it was towards the end of 2013 that they started lifting the fuel rods out.

I think you are right, Ash. I wasn't sure what I was looking at.
I've just noticed on the Google Earth Toolbar, that if you click on the Clock Symbol on the toolbar at the top of the page, a slider comes up which you can drag backwards through a sequence of dates on which aerial images were produced. On 3-12-11 (i.e. UK March 12th 2011) a large part of the view is obscured by what looks like steam or cloud.

EDIT: This is incorrect. 1-4 ARE correct, 5 and 6 are not as portrayed below Ok, I've done a bit of research, and I'm as confident as I can be that this is what we are looking at in these pictures. I've numbered the reactors from 1 to 6:
I've read this morning that Caesium 137 has been detected (back in December) in groundwater 25 meters underneath reactor 4, which is where most of the MOX fuel is, I think. This does suggest, possibly that 'corium' is melting it's way down towards the water table, although I can't rule out other explanations:
Reactor 3 is, I think, the one that is generally accepted is in 'meltdown', although, I think, maybe either 1 or 2 (or both) are also in 'meltdown'.
I'll have to go back and re-read earlier reports later, and then add/correct information to try to build up a better picture of what we can reasonably be certain of.

It looks to be a few hundred yards from Reactor 3 to the water in that dock.

I suppose the reactor may have a cellar or basement or cavity of some sort below ground level. Perhaps the tunnels we have heard about recently connect to these.

It's possible. It's also possible that the caesium 137 came from one of the other reactors, but I'm sure I've read stories that confirm that Tepco was originally saying that the concrete foundations under #4 were cracked, and also stories that a meltdown has occurred in #4 and that the 'corium' has burned down through the concrete, as traces from MOX were also detected, and this can only have come from #4. I'm sure the story says 'groundwater 25 metres under #4', which seems as if it sounds like it's underneath any foundations. 'Groundwater' is a pretty specific term, and I don't think Tepco would use it if they could get away with saying anything else.

"The Tokyo Electric Power Company (TEPCO) will first block the flow of tainted water between the damaged buildings and the tunnels. Workers will begin burying pipes in the ground to carry refrigerants in January, NHK TV network reported. In April, they are set to start draining the contaminated water from the tunnels." Source:
Nowhere have I seen the reason for this refrigeration mentioned, but my guess is that they hope to stop the seepage underground by freezing the earth solid. The tunnels would not then be 'drained', but ice might be chopped out of them with automated mining equipment on the lines of tunnel boring machines. Let's hope that they haven't forgotten that water expands as it freezes.
Near the end of the article 'basements' are mentioned, so perhaps these are spaces below the reactors in which corium or water has accummulated.

That's exactly the reason they are planning to try this, although it's never been attempted on anything like this scale before. I'm sorry I don't have any links, but it's some time since I read that they were contemplating this. A number of 'authorities' pointed out the problems associated with attempting this on this scale, expansion being one. Most of the comments I read at the time weren't very hopeful, and it was seen more as 'At least we're trying something, and we can say as much, and then make the usual excuses when it doesn't work.'
I didn't see any mention of them then trying to 'remove' any ice or frozen ground, they seem to see it as an 'end in itself'. It certainly won't stop corium from boring down to the water table, which is a much more serious threat than leakage into the Pacific.
The idea of the 'ice wall' around the reactors is simply to 'contain' the radiation until they can come up with 'another idea'.
