Fig. 2From: Aeromagnetic survey in Kusatsu-Shirane volcano, central Japan, by using an unmanned helicopterData residual between observed value and synthetic value by the optimal magnetization intensity model in Fig. 3. Standard deviation of data misfit is estimated as 12.7 nT. The closed circle with “Y”, square with “K”, triangle with “M” are the crater lake Yugama of Mt. Shirane, Kagamiike-kita crater, and the main crater of Mt. Motoshirne, respectivelyBack to article page
