Seismology is the scientific study of earthquakes and seismic waves that travel through the Earth. These waves are generated by sudden movements of the Earth’s crust, often caused by tectonic plate activity. Seismologists use sensitive instruments called seismometers to measure and record these vibrations. By analysing seismic data, they can locate earthquake epicentres, determine their magnitudes, and study the Earth’s internal structure. Seismology helps us understand natural hazards, improve building designs to withstand earthquakes, and develop early warning systems. It also provides insights into geological processes like volcanic activity and plate tectonics, helping us better understand our dynamic planet.
