Fig. 2.

A bird’s eye view of the flight path over Shinmoe-dake in the May survey, seen from the southwest, where the base station was located. The colors of the flight path indicate the raw total magnetic field, with warmer colors corresponding to higher intensities. Note that along the majority of the flight path, the flight altitude was lower than the highest elevation of the Shinmoe-dake summit. That is why we had to use Eq. (3) rather than Eq. (2).
