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
Scientists use a recording instrument called a seismograph to detect ground motions caused by seismic waves from earthquakes.
scientists know the exact spot where an earthquake begins because they use a ritcher scale
The maximum intensity is at the epicenter. It is how the scientists calculate the epicenter.

GPS transmitors are used to detect the slow movement of the tectonic plates.
Scientists use devices called Seismographs to determine the epicenter of an earthquake. If 3 or more seismographs detect an earthquake, seismic wave activity can be measured and quantified and then cross-referenced with other data (the primary and secondary seismic waves) to determine the earthquake's location.
Use a seismograph.
