A description of the types of surface and body waves produced by earthquakes, the ultimate cause of shaking and damage. These waves travel at different speeds: P-waves are fastest, then S-waves, then Love waves, then Rayleigh. The observed kinetic energy of Love waves is as large as that of Rayleigh waves through the whole period of analysis. … The horizontal shaking of Love waves is particuly damaging to the foundations of structures. 3. The other surface wave form is called a Rayleigh wave. Further details on the characteristics and propagation of Love and Rayleigh waves … Rayleigh Waves. Question 1 1 pts The fastest seismic waves are: O Love Waves Rayleigh Waves O S-waves OP-waves Question 2 1 pts Why was the death toll from the December 26, 2004 Indian Ocean tsunami ten times higher than that from the March 11, 2011 Japan tsunami? This can be done using surface waves (Love and Rayleigh waves) since their properties (dispersion curves, Rayleigh wave ellipticity) are closely linked to the soil structure. 8 observed Love and Rayleigh waves coming from the same direction, concluding that Love waves do originate in the source region. O warning system and evacuation drills in 2011. better building construction in 2011. The speed with which both types of waves circle the globe is truly mind boggling. The wave animations illustrate wave characteristics and particle motion as listed in Table 1. All surface waves travel slower than body waves and Rayleigh waves are slower than Love waves. 1 Love and Rayleigh Waves Whenever an elastic medium is bounded by a free surface, coherent waves arise that travel along that surface; the amplitude of those surface waves decays with increasing distance from the surface (that is to say, in the Earth, with increasing depth). Rayleigh Waves. Rayleigh waves and Love waves. Answer and Explanation: Become a Study.com member to unlock this answer! Learn love waves and rayleigh waves with free interactive flashcards. Exercise Exercise Fill in the blank. The second type of surface wave is known as a Rayleigh wave. In seismology, Love waves (also known as Q waves (Quer: German for lateral)) are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. Get an answer. Love waves d. A surface wave that causes vertical motion. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases. relative proportions of Love and Rayleigh waves in the am-bient vibration wavefield. 0 Answers/Comments. Your email address will not be published. 19 noted that the greater the distance of propagation of Rayleigh waves, the larger the Love wave energy. Surface waves bring the most destruction to structures. Earthquake damage also results from Rayleigh waves, surface waves which deform materials vertically. Surface Waves Surface waves bring the most destruction to structures. They form when S waves interact with the Earth's surface. In the case of Rayleigh waves, the motion is of a rolling nature, similar to an ocean surface wave. They show the dependence of the velocity on layer thicknesses and material properties (elastic constants). Moreover, the SNR of the Rayleigh wave for both the Z–Z and R–R cross-correlations exhibits two peaks that correspond to the 8 s (secondary) and 16 s (primary) microseisms, respectively. Choose from 9 different sets of love waves and rayleigh waves flashcards on Quizlet. Surface Waves: While body waves, such as P-waves and S-waves, are higher in frequency, move faster, … The second type of surface wave was discovered in 1911 by another Englishman, Augustus Edward Hough Love. Rayleigh waves are formed when the particle motion is a combination of both longitudinal and transverse vibration giving rise to an elliptical retrograde motion in the vertical plane along the direction of travel. Answer and Explanation: That is why there are seismic waves that can only propagate through the Earth's crust called surface waves. Love wave is also a seismic surface wave led to the horizontal shifting of the earth during an earthquake. A Rayleigh wave is a seismic surface wave producing the sudden shake in an elliptical motion, with no crosswise or perpendicular motion. Search for an answer or ask Weegy. It moves along the ground just like a wave moves across a lake or an ocean. The correct answer is not displayed for Written Response type questions. Surface waves (Rayleigh and Love waves) travel only along a free surface or along the boundary between two dissimilar solid media. These waves produce only horizontal motion on the Earth's surface shaking the Earth in a side to side motion. The speed with which both types of waves circle the globe is truly mind boggling. “In that case, the source of Love waves would be very close to the source of Rayleigh waves, if not the same location,” Gualtieri said. 1. miikaaa miikaaa Explanation: Love waves have a particle motion, which, like the S-wave, is transverse to the direction of propagation but with no vertical motion. Love waves shake the earth from side to side in circular or elliptical way. Rayleigh waves, R-waves, are named after Lord Rayleigh (John Strutt), an English aristocrat who, in his work as a scientist and mathematician, developed a detailed mathematical accounting of the type of surface wave named after him. Love waves occur in a thin plate, while Rayleigh waves are a combination of transverse and longitudinal waves on the surface of a half … On the other hand, ref.
