Seismic waves are categorized into three main types based on their motion and propagation:
Primary waves (P-waves): These are the fastest seismic waves and travel through both solids and liquids. P-waves cause particles to move in the same direction as the wave’s propagation, resulting in a back-and-forth compressional motion. They are responsible for the initial, less intense shaking during an earthquake.
Secondary waves (S-waves): S-waves are slower than P-waves and only travel through solids. They cause particles to move perpendicular to the direction of wave propagation, producing a side-to-side shearing motion. S-waves are responsible for the more intense shaking felt during an earthquake.
Surface waves: These waves travel along the Earth’s surface and are slower than both P-waves and S-waves. Surface waves are responsible for the most damaging and prolonged shaking during an earthquake. There are two types of surface waves:
These seismic waves play a crucial role in our understanding of earthquakes and the Earth’s internal structure.
