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 … 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 ).
