I'm a webcam watcher. I watch the Tepco and TBS-JNN cams.
The Tepco webcam is located at the plant whereas the TBS-JNN cam is located on a distant hillside and is focused in on the plant.
It is true that those cams' feeds are censored and sometimes the Tepco webcam cam runs "safe" old loops to censor viewers' observations of ongoing events at the plant.
But not every major event at the plant is censored by the TBS-JNN and Tepco webcam operators.
Recently, a lot of events have been broadcasted.
The events recorded by the TBS-JNN cam here are simply terrifying: a strange blaze, a sharp blast of light and then a purple glow.http://www.youtube.com/watch?v=6zDFlI0GzQQ
Then, we had unprecedented night-time steam and/or smoke releases visible on the Tepco webcam from June 29 - July 1.
Here's a sample that is particularly disturbing because you can see that units 1 and 2 are spewing steam/smoke that is obviously highly radioactive because of the distortions/pixillation. These units rarely emit such plumes.
And the space near unit 4 looks very bad based on the steam/smoke releases from that area
We haven't had releases like this visible since June of 2011
June 26 2011 http://www.youtube.com/watch?v=-NkmSGTzzYI
Another big, recent event was the criticality recorded and available here:
The early morning hours from 24.06.2012
So, it seems to me that the situation is not stable and that Tepco's recent efforts to knock down parts of unit 4 must either:
have been prompted by some severe emergency
have caused caused some severe emergency
I believe everyone at risk of exposure to Fukushima plumes should be paying attention now.
