“…Various analysis techniques using gravity gradient tensors have been suggested and discussed (e.g., Zhang et al 2000;Beiki 2010;Martinez et al 2013;Cevallos 2014;Li 2015). These are considered to be so-called inversion techniques.…”

The dips of boundaries in faults and caldera walls play an important role in understanding their formation mechanisms. The fault dip is a particularly important parameter in numerical simulations for hazard map creation as the fault dip affects estimations of the area of disaster occurrence. In this study, I introduce a technique for estimating the fault dip using the eigenvector of the observed or calculated gravity gradient tensor on a profile and investigating its properties through numerical simulations. From numerical simulations, it was found that the maximum eigenvector of the tensor points to the high-density causative body, and the dip of the maximum eigenvector closely follows the dip of the normal fault. It was also found that the minimum eigenvector of the tensor points to the low-density causative body and that the dip of the minimum eigenvector closely follows the dip of the reverse fault. It was shown that the eigenvector of the gravity gradient tensor for estimating fault dips is determined by fault type. As an application of this technique, I estimated the dip of the Kurehayama Fault located in Toyama, Japan, and obtained a result that corresponded to conventional fault dip estimations by geology and geomorphology. Because the gravity gradient tensor is required for this analysis, I present a technique that estimates the gravity gradient tensor from the gravity anomaly on a profile.

“…However, differentiation of the analytic signal amplitude may amplify high frequencies. Zhang et al (2000) employed the Euler's homogeneity equation for interpretation of GGT data and showed that the standard Euler deconvolution can be extended to where B x , B y and B z are the regional values of components of gravity vector g x , g y and g z to be estimated. Their method uses the full GGT and the components of the gravity vector to provide additional constraints on the Euler solutions.…”
