Rayleigh waves
[ˈreɪli weɪvz]
nounpl: N/A (plural form)
ondas de Rayleigh
1. A type of surface seismic wave that travels along the Earth's surface, causing both vertical and horizontal particle motion in the direction of wave propagation. Named after physicist Lord Rayleigh.
Rayleigh waves are responsible for much of the damage caused by earthquakes because they travel slower than body waves but carry significant energy.
As ondas de Rayleigh são responsáveis por muito dos danos causados por terremotos porque viajam mais lentamente que as ondas de corpo, mas carregam energia significativa.
2. Elastic waves that propagate along the free surface of a solid medium, with amplitude decreasing exponentially with depth into the material.
In seismology, Rayleigh waves are detected by seismometers and used to measure earthquake magnitude.
Em sismologia, as ondas de Rayleigh são detectadas por sismógrafos e usadas para medir a magnitude de terremotos.
Rayleigh waves are a fundamental concept in seismology and geophysics, studied extensively in both Brazilian and international universities. The term is used identically across Portuguese-speaking countries in scientific and academic contexts. Understanding Rayleigh waves is crucial for earthquake engineering and hazard assessment, particularly important in seismically active regions like parts of Brazil and Portugal.
