Have you seen building schematics? There are pipes of water, vents, etc. Air pressure changing as the building collapses pushes air pressure down vents/pipes, those things have to go someplace especially in pipes since they are closed systems. Vents would be pusing air out, but eventually it would flow much more than it was designed for and push out greater amounts of air.
To see simply how this works take a garden hose and blow with your mouth from one end, then use a high pressure compressor on the same end and see the difference in how much distance the water goes from the other end.
