Geologists have created Creep Meters, GPS Satellites, Range/ Laser devices, and Tilt Meters. These instruments help keep track of changes in the land surface and elevation.

The four instruments that are used to detect movement along faults are Tiltmeter, Creep Meter, Laser-Ranging device, and GPS Satellites.

Geologists have developed instruments to measure changes in elevation in tilting of the land surface and ground movements along fault
Geologists can use seismographs to detect hidden faults. When seismic waves encounter a fault, they are reflected off of the fault. Geologists can use this information to chart the location of a depth of a hidden fault.
A fault must be younger than the rock it cuts through.
A sharp cliff caused by sudden movements along dip-slip faults is called an earthquake. It causes the ground to shake for several seconds.
Convergence, divergence and strike slip.
to monitor faults, geologists have developed instruments to measure changes in elevation, tiliting of the land surface, and ground movements along the faults. Geologists use tiltmeters, Creep Meters, Laser- Ranging Devices, and GPS Satellites.
They can't be predicted and that is the problem. Geologists monitor active faults for signs of movement.

Geologists collect data on friction along the side of faults so that they can predict how much pressure is applied on the faults so they can predict how strong the earthquake is.

They map faults, detect changes along faults, and develop a method of predicting earthquakes

GPS itself does not do this. When geologists place recording GPS receivers on opposite sides of the faults that separate the tectonic plates the receivers calculate their positions (just like the GPS navigator in a car does) and when the geologists analyze the collected data they can make maps of plate movements.
Geologists can determine earthquake risk by locating where faults are active and where past earthquakes have occured.
So that geologist can predict how much force of pressure applied on the faults to predict how strong the earthquake.
