2D kernel-based imaging of coda-Q space variations in the Gargano Promontory (Southern Italy)

Crustal seismic attenuation in the Gargano Promontory (Southern Italy) was inferred by analyzing coda waves of about one hundred small magnitude earthquakes recorded by the OTRIONS local seismic network. Coda attenuation Qc was computed using the Sato (1977) model, i.e. the assumption of single back-scattering, at different lapse times and at different frequencies. Average Qc is comparable with the same quantity measured in the adjacent area of...
