WebMay 20, 2015 · Analysis of receiver functions for 58 stations in northern Japan Anisotropy is located in both the upper and lower crust Anisotropy displays E-W orientation in the lower crust 1 Introduction Seismic anisotropy is the rock property describing the variation of the speed of seismic waves with the propagation direction at a given point. WebMar 27, 2024 · The receiver function (RF) technique is an effective method for studying crustal structure. For a single station, the average 1-D crustal structure is usually derived by stacking the radial RFs from all back-azimuths, whereas structural variations (such as dipping discontinuities or anisotropy) can be constrained through analysis of waveform …
Lower crustal anisotropy or dipping boundaries? Effects on receiver …
WebSep 15, 2014 · The receiver function analysis technique isolates teleseismic mode conversions originating at velocity contrasts beneath a seismic station. We show that dipping isotropic contrasts as well as small (<10%) anisotropy generate first-order (i.e. Moho-sized) arrivals in receiver functions. WebIn recent years, P -to- S (or Ps) receiver functions (RFs) have been widely used to resolve complex media, such as dipping interfaces and layered anisotropy. Receiver functions represent P -to- S conversions at seismic discontinuities and can be expressed into a radial and a transverse component (Langston 1977; Vinnik 1977 ). hies leaflet

WebOct 1, 2024 · The crustal anisotropy mainly develops due to structural features such as faults, layering, flat mineral alignment, and regularly oriented cracks in the upper crust (e.g., Crampin, 1981; Mainprice et al., 2000; Boness and Zoback, 2006; Brownlee et al., 2024 ). WebDec 7, 2016 · Crustal anisotropy is crucial to understanding the evolutionary history of Earth's lithosphere. Shear wave splitting of Moho P -to- S converted phases in receiver functions (RFs) have been often used to study crustal anisotropy.
