Fig. 3.From: Fault plane of the 1964 Niigata earthquake, Japan, derived from relocation of the mainshock and aftershocks by using the modified joint hypocenter determination and grid search methodsRelocated hypocenters using JMA data performed by the GS method. (a) Final hypocenters relocated by using the GS method. The Awashima Uplift Zone (AUZ) is shown by a thick broken line. Symbols are the same as those in Fig. 2. (b) Distribution of the sum of squares of residuals (SSR in s2) for the mainshock calculated by using the GS method.Back to article page
