Combining seismic reflection with multifold wide-aperture profiling: An effective strategy for high-resolution shallow imaging of active faults

摘要: [1] Shallow imaging of fault zones is a challenging task. We investigate if this issue can be successfully addressed by combining reflection seismics with non-standard multifold wide-aperture profiling, strategy pertaining to crustal scale exploration so far. Near-offset and data are simultaneously recorded along two profiles in small basin crossed an active Southern Italy. Imaging consists multiscale seismic tomography complemented CDP processing near-offset reflections spanning large offset range. By smooth Vp reflectivity images we pinpoint the location yield valuable picture basin. Performance each technique strongly varies surveys depending on local geology. Thus, combined not only yields complementary for enhanced interpretation, but also allows extending range applicability shallow detection, reducing risk unsuccessful investigations.
