a The magnetic anomaly in the area of Figure 14 from which the linear trend has been removed. The original data are a portion of the Aeromagnetic Anomalies Database of Japan (Nakatsuka and Okuma, 2005). b The magnetic anomaly recovered by the optimal model in Fig. 23. The coordinate system of these figures is UTM, and the color scale indicates the magnetic anomaly in nT
