“…Since no direct information about the resolution and covariance of the final solutions can be obtained when using a conjugate gradient method such as LSQR, only tests with synthetic data can provide some insight on the solution quality. The advantage of such tests is that they provide an overall estimation of the effect of not only data quality but also model parameterization and damping on the solution quality (Kissling et al, 2001). In the present study, we have chosen to perform "checkerboard" tests (Spakman, 1988;Humphreys and Clayton, 1988;Papazachos and Nolet, 1997a).…”

“…Given a linearized seismic inverse problem, one very rough estimate of the illumination of the model space is given by the hit count, which sums up the number of rays which contribute to the solution at a node. This estimate, together with the evaluation of the diagonal elements of the resolution matrix (RDEs), which quantify the amount of independence of a model parameter solution, indicate the resolving power of the data set in the model [Haslinger et al, 1999;Kissling et al, 2001]. RDEs are strictly dependent on the choice of damping factors: the larger these are, the lower becomes the value of RDEs.…”

.[1] A new image of Mount Vesuvius and the surrounding area is recovered from the tomographic inversion of 693 first P wave arrivals recorded by 314 receivers deployed along five profiles which intersect the crater, and gravity data collected in 17,598 stations on land and offshore. The final three-dimensional (3-D) velocity model presented here is determined by interpolation of five 2-D velocity sections obtained from sequential integrated inversion (SII) of seismic and gravity data. The inversion procedure adopts the ''maximum likelihood'' scheme in order to jointly optimize seismic velocities and densities. In this way we recover velocity and density models both consistent with seismic and gravity data information. The model parameterization of these 2-D models is chosen in order to keep the diagonal elements of the seismic resolution matrix in the order of 0.2-0.8. The highest values of resolution are detected under the volcano edifice. The imaged 6-km-thick crustal volume underlies a 25 Â 45 km 2 area. The interpolation is performed by choosing the right grid for a smoothing algorithm which prepares optimum models for asymptotic ray theory methods. Hence this model can be used as a reference model for a 3-D tomographic inversion of seismic data. The 3-D gravity modeling is straightforward. The results of this study clearly image the continuous structure of the Mesozoic carbonate basement top and the connection of the volcano conduit structure to two shallow depressions, which in terms of hazard prevention are the regions through which magma may more easily flow toward the surface and cause possible eruptions.
