Here's why:
* Seismic Waves: These are the waves that travel through the Earth's interior and are generated by earthquakes, volcanic eruptions, or other disturbances.
* Crustal Movements: Seismic waves are essential for understanding how the Earth's crust moves, deforms, and interacts with the mantle.
* Earthquakes: Seismologists study earthquake waves to understand their origins, propagation, and effects on the Earth's surface.
While other fields like geology and geophysics also contribute to understanding the Earth's crust, seismology specifically focuses on the wave phenomena that drive crustal movements.
