Figure 11

Magnetic anomaly maps of the Minami-Hiyoshi Seamount area before and after leveling correction. Unnatural anomalies in the northeastern part of the map before correction (A) almost disappear, and the contours generally become smoother after leveling correction using a filtering width of 3 h and a weight distance of 0.1 km (B). The contours are at 50 nT intervals; thicker contours are at 200 nT intervals.
