You can think of this in the same way that satellites work to find your location for the GPS in your car. An earthquake happens and it is picked up on 3+ seismometers. These seismometers measure the waves that the earthquake produced and the velocity at which they are traveling and you look at where all the seismometer calculations run together. You have the epicenter of your earthquake.

Seismometers help by detecting and measuring seismic waves caused by earthquakes or other sources of ground motion. By providing data on the intensity and location of seismic events, seismometers help scientists monitor and study Earth's seismic activity, improve earthquake early warning systems, and assess potential risks to infrastructure and communities.

Seismometers are instruments that measure ground motion during an earthquake. They detect the movement of the ground caused by seismic waves passing through the Earth. The data recorded by seismometers can help scientists analyze and characterize earthquakes.
Earthquakes are detected and measured using seismometers or seismographs.
Seismometers, strain gauges, tiltmeters, creep meters, high precision GPS, Terrestrial laser scanning equipment and synthetic aperture radar amongst other things are equipment used by scientists to monitor earthquakes and the resultant deformation.Seismometer

Seismometers are interested in the vibrations of the Earth, for different reasons. Some may be interested in the geological process. Some in the response of buildings and other structures. Seismometers can respond to very low frequencies, down towards 1 milli-Hertz. And up to a few hundred Hertz. These machines do not 'use' frequencies, they merely record what is naturally happening.
Scientists use seismometers to study earthquakes. Seismometers are instruments that detect and record the vibrations caused by seismic waves during an earthquake. These devices help researchers analyze the location, magnitude, and effects of earthquakes.
Typically, at least three seismometers are needed at a given place to fully record the motions arising from earthquake waves. With three seismometers, data can be used to triangulate the epicenter and determine the magnitude of the earthquake. More seismometers can provide more detailed and accurate information about the seismic event.
