We report on the 3 D‐magnetic structure model of Io To based on the airborne geomagnetic surveys in January 2007 and December 1998. We used a 3 D‐magnetic tomography inversion method where the volcanic edifice was sliced into three horizontal layers (above 250m, 250 ‐ 750m, 750 - 2500m in depth) and horizontally divided into prisms with a mesh size of1km ×1km. We assumed that each prism possessed a homogeneous magnetization, and analyzed the intensity of the magnetization of each prism using a conjugate gradient method for calculation. The result showed a characteristic feature that the magnetization intensities in the central part of layers 2 and 3 are lower than a circumference part. The result may suggest participation of magma.Journal
