We present a method to estimate seismic depth uncertainty (DU) from velocity in a vertical transverse isotropy (VTI) medium that is based on normal moveout (NMO) travel-time calculations and a detectability criterion. We provide the mathematical derivation and demonstrate the method using the synthetic 3D SEAM model. The result demonstrates the accuracy and robustness of the method for successful depth uncertainty estimation.
