The GPS can be used to measure the horizontal and vertical location of various locations on land. After an earthquake, GPS measurement are repeated, showing how far, if any, the land has moved as a result.

A seismometer would measure earthquakes, but there is no such activity on the moon to measure.

I was confused about this too, I'm not quite sure but I think they measure the movement with GPS, they move about a centimeter per year. But the some people say that the motion is different and that you use a Seismometer, the same thing used to measure earthquakes.
global positional system (GPS) is used for finding tracks like tracking earthquakes or navigation too.
Tiltmeters use laser technology and GPS equipment to measure the slope of the ground level very accurately. If there is an abnormal, sudden tilt in the ground, there is a chance that an earthquake is on its way.

Two separate systems used to measure earthquakes are important for accuracy. More than one system to measure gives scientists an accurate measurement of an earthquakes strength.
A seismometer is used to measure the strength of earthquakes.

Seisomographs measure earthquakes.
