I derive and analyze an explicit formula for a generalized semblance attribute, which is suitable for velocity analysis of prestack seismic gathers with distinct amplitude trends. While the conventional semblance can be interpreted as squared correlation with a constant, the AB semblance is defined as a correlation with a trend. This measure is particularly attractive for analyzing class II AVO...

The imaging of volcanic systems is a challenging topic that attracts the scientific community’s attention. characterization structures and rock properties by means seismic active methods becoming fundamental for providing ultra-high-resolution images interest. Solfatara Volcano quiescent volcano in Campi Flegrei resurgent nested caldera continuously under investigation monitoring its shallow ac...
