Depends on how this satellite was created.
Like with Moon - it's more about that part of Earth crust was thrown into orbit, giving remaining plates free space to move. Normally planetary crust is more rigid and have way less activity since all plates are tightly coupled and there's there's nowhere to move. By removing one of places rest was given ability to shuffle around, moving back and forth.

Like Mars have two satellites, but since his crust is "unbroken" - nothing happening there.
