Web27 de mar. de 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 … WebAn introduction to the receiver function analysis technique that is common in global seismology.
