I suppose all of that could have contributed, but no doubt therell be a full enquiry.Some allegations that the complex has been sinking the last few years since it was built on a former swamp 40 yrs ago. A new building is going in across the street & the navy made a 3.39 size earthquake seismic event with artillery practice not too far away a couple of weeks ago.
Awful, awful stuff. Hope they find more survivors & not more dead.
Just awful for the families and friends of those whove died.
