Seismic Interferometry

Seismic interferometry is a technique that uses recordings of natural or artificial seismic waves to create detailed images of Earth's subsurface structures. By analyzing how waves emitted from one point are received at another, scientists can reconstruct the signals as if a source was placed directly at different locations. This method allows geophysicists to study underground features—such as oil reservoirs, fault lines, or mineral deposits—without needing to inject signals at every point. Essentially, it leverages existing seismic data to 'interfere' and generate new insights, improving our understanding of Earth's interior efficiently and non-invasively.
