Multiridge and ScalFun methods: spherical source embedded in a heterogeneous medium. (a) Map of the modeled vertical component of the deformation field calculated on a flat surface level of \(\,z=0\). The black dashed line indicates the AA’ trace. (b) AA’ profile of the vertical component of the deformation field. (c) The results of the Multiridge method applied to the AA’ noise profile; the red solid lines, which represent the regression lines, estimate the source position at their intersection, and the black solid line indicates the real source depth. For each regression line we indicate the coefficient of determination (R2); (d) the results of the ScalFun method applied to the central cyan multiridge subset reported in (c), where \(w\) represents the values of the field corresponding to the selected ridge.
