|Abstract: ||Elastic parameters derived from seismic reflection data provide
information on the lithological contrast at an interface and support the geological
interpretation.We present a method to estimate elastic parameter contrasts
at a given interface in a 1-D layered medium from PS-to-PP amplitude ratios.
The method is applied to synthetic data to demonstrate its possibilities and limitations.
First results for real data acquired in the Campi Flegrei caldera (southern
Italy) reveal a gas-bearing layer at around 3 km depth and indicate a strong
negative velocity contrast at 7.5 km depth, possibly related to the presence of
