In the Oklahoma City bombing a massive explosion ripped the entire front side and much of the structure off the building. No building is designed to withstand a terrorist with a huge bomb parked just feet from the front of the building.
Imagine that high rise in San Fransisco that is leaning several inches. That has to be a scary place to live, especially now.

that's Millennium Tower at 301 Mission Street- sunk 18 inches and tilted 14 inches overall
I didn't check but I don't think it is built on fill (like most of North Beach). The Miami area is limestone and is getting salt water intrusion as sea levels rise, but I dunno if that figures into this collapse.
The N. bldg. in the center collapses first in the videos, and 'pulls' the other bldg. down.
There has been talk about stuff on the roof, and lots of other things. We'll know more when a forensics team of structural engineers gets in there.
