WebSurface waves are the result of P- and S-waves interacting with the surface of the Earth. These waves are dispersive , meaning that different frequencies have different … WebBody waves (to some extent) and especially surface waves show dispersive characteristics during propagation. In Dr. Christopher Liner's book [Elements of Seismic Dispersion (2012)], this phenomenon is quickly attributed to propagating seismic energy being frequency-dependent.I've heard this phrase for a long time, and I am still unsure how to …
WebRayleigh waves involve interaction between P and 5 waves at a free surface; thus we must further explore the nature of body-wave reflection coefficients at the free surface. We consider the two cases shown in Figure 4.1, for incident P and incident SV plane waves impinging on a free surface. A free surface requires the tractions to vanish at x 3 = 0; σ … WebUSGS Earthquake Hazards Program, responsible for monitoring, reporting, and researching earthquakes and earthquake hazards
WebGround shaking is a term used to describe the vibration of the ground during an earthquake. Ground shaking is caused by body waves and surface waves. As a generalization, the severity of ground shaking increases as magnitude increases and decreases as distance from the causative fault increases. Although the physics of seismic waves is complex ...
