WebAug 9, 2024 · In this study, we analyze the temporal and spatial characteristics of Rayleigh wave microseisms recorded in eastern China. Although some studies investigated the characteristics of microseisms, origins of microseisms related to Rayleigh waves recorded in this region are yet to be studied. WebRayleigh 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 …
WebThe Rayleigh wave characteristics have been separated from the velocity records using the method of time–frequency decomposition. Finally, a collected database of 6-DoF records was used for determining the relation between the rotational ground movement, seismic energy and vibration frequency of the tremor. ... WebSep 30, 2024 · That is, the propagation characteristics of leaky Rayleigh waves on the medium’s surface were not only related to soil moisture, but also other factors, such as surface roughness, porosity, and temperature [71,72,73]. Since this study used a superficial wave, there was a limitation of effective depths to estimate soil moisture (a depth of ...
WebJun 22, 2024 · The 10 s Rayleigh wave attenuation image shows significantly high-attenuation characteristics in the Tarim Basin, Junggar Basin, and Bohai Bay Basin, all of which host thick sedimentary layers, revealing that the distribution of sediment is the main factor leading to the attenuation of seismic waves at a period of 10 s.
WebFeb 24, 2024 · They 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 …
