It's believed that there is no control at all, and all the people can do is wait and see if the three reactor hulls are holding. If they also melt, or explode, it would have unforeseen consequences. If you compare the upper photo, with former satellite pictures on Google Maps, it's clear what massive forces are at work. Debris on the neighbor buildings, and a lot of buildings at the seaside are completely gone. You can see the remaining ruins from some of them.
Update: Full view of the explosion of reactor 3 [Video] Mind the size of debris falling down from the cloud.
