Amazing that the structure remained as intact as it did. The foundation was
weak, but the building sure wasn't. Lots of the windowpanes weren't even
broken. It looked so undamaged that I thought, after seeing just the first
photo, that it was a fake. Obviously not.

Sorry. I meant to agree with Robert, but my computer hiccupped. So,
I guess I'll re-iterate (again) that it's amazing the building didn't
crumble more.

I suspect that the reason it gives that appearance is because the buildings
collapse was cushioned a bit in the soft mud, allowing the stresses to snap
things sequentially as it fell rather than an explosion where the energy is
applied all at once.

If you are not part of the solution, you are not dissolved in the solvent.

Yeah but . . . (-: Many of the windows didn't even break. That's just
bizarre. I wonder what the "rate of descent" was. I guess if it tipped over
gradually enough there wasn't a big slam at the end, but still, it's a
pretty amazing site. Or sight. Or even cite. Thanks for posting that,
Jeff.
I guess I am used to seeing collapsed buildings in the aftermath of
earthquakes where the buildings fall because they are shaken apart. The
Shanghai building didn't have to endure any pre-collapse shaking and I am
betting the ground gave way slowly and the pilings appear to have bent
before they broke, asborbing both time and energy and moderating the forces
on the building. Still, what a ride that must have been. Sounds like a
project for Disney World. Here are some random EQ photos, FWIW:
