Abstract

Reflection responses due to a buried explosion and a vertical point force have different characteristics. The difference is twofold: (1) the vertical point force generates shear wave in addition to P-wave; (2) the explosive source generates ghost event (reflection from the free surface) which interferes with the major arrivals. Introduction of viscoelasticity into the medium reduces the seismic amplitudes and broadens the wavelets. In case of a high velocity layer sandwiched between two low velocity structure, converted reflections (especially in the radial component section) can help to resolve partially the thickness of the layer.
