Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It involves measuring seismic waves, which are generated by a variety of sources including tectonic movements, volcanic activity, and man-made explosions. Seismologists analyze these waves to understand the internal structure of the Earth, the occurrence and characteristics of earthquakes, and the processes that cause seismic events. The discipline encompasses the development of instruments such as seismographs, methodologies for analyzing seismic data, and the assessment of earthquake risk and mitigation strategies. Overall, seismology plays a critical role in enhancing our understanding of geological processes and in reducing the impact of earthquakes on society.
