 Seismic interferometry

Seismic interferometry is a technique used in geophysics and seismology to extract useful information about the subsurface from recorded seismic data. It relies on the principle that seismic waves, which are generated by various sources (such as earthquakes, explosions, or controlled sources), can be treated as if they interact with the Earth's subsurface structures, allowing researchers to infer the characteristics of those structures.
