noun
Rayleigh wave
A type of surface seismic wave that travels along the Earth's surface, causing both vertical and horizontal ground motion. Technical term used in seismology and geophysics.
レーリー波は地震の表面波の一種で、地盤を上下に揺らす。
Rayleigh waves are a type of seismic surface wave that shake the ground up and down.
Surface waves include both Rayleigh and Love waves; レーリー波 is a specific subtype.
Named after the British physicist Lord Rayleigh (John William Strutt), who predicted the existence of these waves in 1885. The Japanese term is a direct borrowing from English 'Rayleigh wave', with the katakana rendering レーリー reflecting the English pronunciation.
