Shake, Wave
You're trying to use your fingers to cause a landslide so you have to shake the earth. You probably won't succeed, but the best you can do is to shake your hands on the dirt as hard as you can. It looks like you're trying to wave at the ground now.
Imagine shaking your fingers at the dirt. Do you think you can shake the dirt hard enough to cause a landslide (spoilers, no).

You think you finally got the earth to shake but when you look down it's just your shins (しん). Darn you shins, I thought I made some progress. Hey wait... why won't you stop?!
Imagine your shins shaking, your hands are waving, and they won't stop. No! You shouldn't have tried to start a landslide. This was a bad idea!
