You have to basically land right next to them, and you cannot slam attack or it won't trigger. Do a 'hard landing' without sliding or meleeing and it will trigger. If it hits them, it knocks over everything except things specifically with knockdown immunity, like some bosses.

The damage seems to be blast damage, but it may be raw physical damage. I have never seen a impact hammer trigger from it, so I doubt its impact damage like some people think.
