Interesting, from the second pic it looks like reactor building 4 was crushed inward at the top by the blast wave from the building 3 explosion, crushing even the concrete structural beams and columns.
You can also see a 60 ft diameter hole in the turbine building from something lofted by the explosion, possibly the top of the secondary containment structure.
