Fig. 4.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 both JMA and ISC data performed by the GS method. (a) Hypocenters relocated by using the GS method. Symbols are the same as those in Fig. 2. (b) Distribution of the sum of squares of residuals (SSR) for the mainshock calculated by using the GS method.Back to article page
