Distribution of highly magnetized lava flows with normal polarity. a geographic distribution, b profile across the spreading axis to the off-axis area including the Kairei field, and c profile across the spreading axis to the off-axis area including the Yokoniwa field. Magnetization intensities of estimations with high coherency (> 0.5 in both x and z directions) and normal polarity (phase of from − 30 to 30 in both x and z directions) are selected and shown as a rainbow-colored circle in (a) and as a black circle in (b) and (c). White circles in (a) show the observed area in which the estimation of absolute magnetization from magnetic anomaly was conducted. The raw data of magnetic anomaly along dive 6K#1331 are cited from Fujii et al. (2016a)
