Seismic waves are primarily categorized into two types: body waves and surface waves. Among body waves, primary waves (P-waves) exhibit particle motion in the same direction as wave propagation, while secondary waves (S-waves) have particle motion perpendicular to the direction of propagation. In contrast, surface waves, which travel along the Earth's surface, also involve particle motion but have more complex motion patterns. Therefore, both P-waves and S-waves exhibit distinct particle motion related to their propagation.
