The failure points were the same walls and slabs not tied properly into columns that's a roof slab hanging off the building cantilevered structures, or structures that were asymmetric, that shook violently and came down, poor building materials, not enough concrete, not enough compression in the blocks, rebar that was smooth, rebar that was exposed to the weather and had rusted away.
