ARRAY ANALYSIS OF AIR-GUN SEA-SHOTS RECORDS FOR IMAGING THE HIGHLY HETEROGENEOUS CRUST BENEATH CAMPI FLEGREI CALDERA (ITALY)

Abstract

An extended active survey SERAPIS (Seismic Reflection Acquisition Project for Imaging Structure)was performed on September 2001 in the Gulfs of Naples and Pozzuoli.The aim of experiment is providing new insights on the Campi Flegrei caldera structure and investigating its feeding system (Fig.1). In the Solfatara crater (Fig.2)was deployed an array of 28 vertical-componentand 4 three-component sensors with an aperture of about 0.2km. There ceivershada natural frequency of 1Hz. About 3000 air-gunsea-shots wereshot(Fig.3). In figure 4 are shown examples of there corded wave form s.
