From: Multiridge Method for Studying Ground-Deformation Sources: Application to Volcanic Environments
Multiridge and ScalFun methods: the Okmok volcano case. (a,b) LOS deformation in the E-W and N-S profiles evaluated from Fig. 7(b). (c,d) The results of the Multiridge method applied to the E-W and N-S profiles; (c) 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); (e,f) the results of the ScalFun method applied to the central cyan multiridge subsets reported in (c,d), where \(\chi \) represents the value of the field corresponding to the selected ridge.
