Rayleighaaltoja
Rayleighaaltoja, the Finnish term for Rayleigh waves, refer to a type of seismic surface wave that travels along the interface between two media, typically the Earth's crust and its underlying mantle. The waves were first described in 1885 by Lord Rayleigh, who demonstrated that such waves result from the combined effects of shear and compressional motion within a homogenous elastic medium.
These waves are characterized by elliptical particle motion at the surface, with both vertical and horizontal
In the field of earthquake engineering, Rayleighaaltoja are a major contributor to ground motion that promotes
Overall, Rayleighaaltoja remain a foundational concept in both natural hazard assessment and applied physical sciences, bridging
