Supposedly, you use a certain type of seismometer. But in that case, how could a deep earthquake far away register as "higher" than a shallow earthquake that's up close? Sure, the deep earthquake may release more energy, but much of it is dissipated by the time it reaches the seismometer (and the peak ground velocity/acceleration, which is what affects the seismometer, would also be smaller for the deep [but bigger] earthquake).
