Because you can hear the audio.
Don't know the composition yet, EVERYTHING on this thing is in French. I took a lot of Latin, but it doesn't make me a good reader of French... the premise is what I was going for anyway. If you want to start comparing the two beyond the type of collapse, I will argue that this building is not an acre in diameter, with 20 acres of floors above it. Massive forces. Massive weight. Chains and weakest links.
Also... the second shot... watch the corner closest to the camera all the way down... and when you cannot see it anymore hit pause, and look at the crane on the ground. You can see it ALMOST all the way to the ground before the dust cloud... and if you listen to the audio you can hear it continue to crush after the dust... and then stop.
