A receiver function is a geophysical tool used in seismology to analyze the structure of the Earth's crust and mantle beneath a seismic station. It is particularly useful for studying the transition zone between the crust and the underlying mantle, as well as for investigating lithospheric and asthenospheric properties. Here's how it works: 1. **Seismic Wave Propagation**: When an earthquake occurs, it generates seismic waves that travel through the Earth.

A processed record that isolates relative arrival times and amplitudes of converted and reverberated seismic waves by reducing the common source and propagation response. P-to-S conversion and S-to-P conversion at contrasts in seismic velocity can constrain interface depths and sharpness. Interpretation requires a velocity model and checks for crustal multiples, dipping interfaces and seismic anisotropy.
