Seismic reflection data processing in active volcanic areas: an application to Campi Flegrei and Somma Vesuvius offshore (Southern Italy)

摘要: The Campanian volcanism develops near the sea. Therefore, geophysical study of marine environment is a key to better understanding tectonic evolution and origin in area. An abundance high quality seismic data sector, where little direct information available, critical volcanism. This paper concerns reprocessing reflection dataset acquired Naples Bay processed during 1973. Even though overall was for that time, course their acquisition technological limits have been overcome by new processing. Our aimed at: 1) reduction random noise data; 2) removal unwanted coherent events; 3) spatial aliasing means trace interpolation on Commod Shot Point (CSP) gathering; 4) improvement resolution wavelet with spiking deconvolution algorithms finally 5) reposition reflectors correct locations space-TWT domain dip moveout post-stack time migration. A comparison between old shows sections are characterized much higher S/N ratio. Diffraction hyperbole has collapsed. Reverberations, ghosts multiples removed or greatly attenuated, especially interest, allowing us follow them more detail greater continuity. Furthermore, boosted reprocessing, interpreter evaluate reflector position continuity detail. reinterpretation phase such lines, already an advanced stage, will therefore allow us gain insights into structural setting bay, aim exploring connection tectonics
