| Tóm tắt≠ | Receiver Function (RF) analysis is a seismic method that isolates P-to-S wave conversions at crustal and mantle discontinuities using teleseismic records from distant earthquakes. Introduced by Langston in 1979, RF analysis provides a cost-effective way to determine crustal thickness, Poisson's ratio, and upper mantle structure without requiring active seismic sources, making it a workhorse technique in crustal and lithospheric studies. | Seismic Full-Waveform Inversion (FWI) is a computational technique that reconstructs detailed subsurface velocity and impedance models by iteratively fitting synthetic seismic waveforms to observed data. Introduced by Albert Tarantola in 1984, FWI has become the leading method for high-resolution imaging in exploration geophysics, engineering seismology, and subsurface characterization. |
