Abstract

One of the applications of seismic interferometry (SI) by cross-correlation is the retrieval of the reflection response of the subsurface from ambient seismic noise recorded at the surface. We apply SI to ambient-noise data recorded in a desert area in North Africa. The retrieved results show distinct coherent events with hyperbolic moveout. We compare the retrieved results with results from an active reflection survey recorded at the same location. We apply standard seismic processing to the retrieved results and obtain a stacked time-migrated reflection profile of the subsurface.
