If the user clapped their hands, they would just violently shake themselves. It wouldn't really slow them down while falling to an extent good enough to be worth it, but it would cause a great deal of damage that Aura would need to block. So overall, it just fails as a landing strategy.

Combined with Wind Dust, then it could work, if Wind does really give it a blowback effect or something similar. Then it goes from "useless and worthless" to just "impractical".

After all, if the user just threw a Wind Dust crystal below themselves and shot it, the explosion would be miles more effective at slowing their fall, and they would deal severely less damage to themselves than if they directly inflicted an earthquake on themselves.

As for range, I agree with Vedran. 30m is fine. Big enough to be useful, not big enough to be ridiculous, and logically the vibration gets weaker the further away it is from the point where it began, so it wouldn't be so extreme it could level a city.
