Abstract
Seismic interferometry can reconstruct reflection responses by cross-correlation of transmission responses on the surface. An advantage of this method is that we can simulate as many shot records as there are receivers with only one shot record. We applied this method to inverse VSP data acquired by one explosive source in the subsurface at a civil construction site in Mizunami, Japan. From the observed transmission records, shot gathers are reconstructed applying the cross-correlation, and following data processing including poststack migration we obtain a two-dimensional subsurface image. This section is clear enough to evaluate subsurface structures.
