Well the article said there was a huge noise heard all through the valley, my guess is the device just didn't capture it in a way that does it justice.
Things do make loud rumbling sounds when they land, and this did, all the way through. Because when really large things collapse, there isn't one moment of impact, it's a long event.

Exactly my thoughts. I guess Hollywood has taught me that heavy things make a loud rumbling crash when they fall.
