Since it unknown at this time, what caused this collapse, nothing can be ruled out. I am certain when day dawns in about nine hours, some of the possibilities as to why this happened will be ruled out within twenty-four hours or two working days, or an answer could be found in the same time span.
The cause will be known within a matter of weeks, would be my best guess, from reading this thread, and listening to the news. But I am no expert, so take all I just typed with a grain of salt.
Prayers for all those affected, and extra prayer for the victims and their families.
“The cause will be known within a matter of weeks,”
Bingo. It’s going to take a while. All of the steel is still there so we will know in time.
