Abstract
We demonstrate that near-surface heterogeneities can be im- aged by natural migration of backscattered surface waves in common shot gathers. No velocity model is required be- cause the data are migrated onto surface points with the virtual Green's functions computed from the shot gathers. Migrating shot gathers recorded by 2D and 3D land surveys validates the effectiveness of detecting near-surface heterogeneities by nat- ural migration. The implication is that more accurate hazard maps can be created by migrating surface waves in land sur- veys.
