Fig. 3: Posterior probability density (PPD) profiles.
From: Progressive underplating of mafic material at mid-crustal depth beneath Ischia volcano, Italy
PPD of the velocity with depth (panels i) for the stations IOCA (a) and IMTC (b), solid white line for the mean model, dashed lines mark the 95% confidence interval, and background color for the full PPD. Panels ii show the interface distribution at depth (IF-DIS). The fit between observed and synthetic RFs for the three Gaussian parameters (red for the observed and black for the synthetic RF) is shown in panels iii for Gaussian filter 8, iv for Gaussian filter 4, v for Gaussian filter 2. c Sketched interpretation of the velocities at depth for IOCA (c i) and IMTC (c ii).
