http://masw.com/files/DAL-03-A.pdf WebRayleigh waves are characterized by vertical motion of the ground surface, like waves on water, while Love waves are characterized by horizontal motion. Both Rayleigh and Love waves are about 10% slower than S-waves (so they arrive later at a seismic station). Surface waves typically have greater amplitudes than body waves, and they do more damage.

WebJun 5, 2024 · Dunes are associated not only with topographical variation but also with variation in seismic velocities. In the field, Criswell et al. measure a surface wave speed of 120 m/s on an aeolian desert dune, while, more recently, Vriend et al. measure a P wave speed of 200 ± 20 m/s in a near-surface layer and 350 ± 30 m/s in the bulk, with … WebJan 1, 1999 · The frequency-dependent properties of Rayleigh-type surface waves can be utilized for imaging and characterizing the shallow subsurface.

WebAug 31, 2013 · The optimal recording of ground roll requires field configuration and acquisition parameters favorable to planar, fundamental mode Rayleigh waves rejecting all other types of acoustic waves. Rayleigh waves can be treated as horizontally traveling plane wave after they have propagated some distance that is close to the offset from the source … WebS waves, also known as secondary waves, are shear waves that arrive after P waves and have a side-to-side motion. The epicenter is the surface location directly above the focus. Surface waves (yellow concentric lines) travel slower than body waves and along the surface of the Earth generating two types of waves: Love waves and Rayleigh waves.

http://masw.com/files/XIA-99-04.pdf WebThey include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel. They are called primary waves because they are the first type of wave to arrive at seismic recording stations. P waves can travel through solids, liquids, and even gases.
