Title: | Analysis of PS-to-PP amplitude ratios for seismic reflector characterisation: method and application | Issue Date: | 2007 | Series/Report no.: | INGV- DPC/V4 PROJECT V4: TASK 2 | Keywords: | Campi Flegrei caldera | Subject Classification: | 04. Solid Earth::04.06. Seismology::04.06.10. Instruments and techniques | 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 partial melt. |
