How do geologist track earthquakes?

Geologists track earthquakes using a network of seismometers, which are sensitive instruments that detect and record ground motion caused by seismic waves. These devices measure the intensity, duration, and frequency of vibrations, allowing scientists to determine the earthquake's location, depth, and magnitude. Data from multiple seismometer stations are analyzed to create seismograms, which provide insights into the earthquake's characteristics and help assess potential impacts. Additionally, geologists may use GPS technology to monitor ground deformation, which can indicate tectonic activity.
