At many different earthquake centers. When an earthquake happens the tree nearest earthquake centers record the magnitude and intensity of the seismic waves produced by the earthquake in order to find the origin or epicenter
They do not predict earthquakes.

they check the intensity or magnitude of the earthquake.

Seismographs placed around the planet detect the vibrations and calculate the epicenter using triangulation.
