And how does that relate to Millennium tower which has already "sunk a foot and a half"? What if high rise building is anchored through all liquefaction-prone layers but the layers start to shift (they are on slight incline) when they get liquified? I am not expert but I can imagine it is possible that, if the structural support is long enough, just few inches of lateral movement may completely compromise the support.
