This article analyzes the physical properties of surface waves and their significance in seismology. Surface waves are generated as a result of the impact of mechanical objects on the surface and consist of a combination of longitudinal and transverse oscillations. The article provides a detailed description of the characteristics of Rayleigh and Love waves, the conditions of their propagation, and how they move along the Earth’s surface during an earthquake. It is noted that Love waves have a dispersive nature and that the particle motion of Rayleigh waves takes the form of a retrograde ellipse. Additionally, the article discusses the propagation of global surface waves across the Earth during earthquakes and their importance in seismic records.
