This is the basement, part of concrete molding from a section above tore through this section ripping the rebar inside the above floor along with it.  

The terra cotta tile dangling above is a piece from the roof above.  That particular piece traveled over 200 feet and landed in a web of tangled rebar.  The rebar is encased in the concrete pulling down.  {Rebar is a common steel bar or mesh of steel wires commonly used as a tension device in reinforced concrete and reinforced masonry structures, to strengthen and hold the concrete in compression. The surface of the rebar may be patterned to form a better bond with the concrete}.

The sound of this sudden decaying moment was deafening.  Although it wasn't heard, one can only imagine, the amount of skill (welders) to put the maze of rebar together.  Certain countries will reuse the rebar, and sold for its worth in weight as scrap.
