Multiple geophysical techniques have been applied to geothermal exploration within the Teshikaga area. The three-dimensional inversion of HeliFalcon^® airborne gravity gradiometry (AGG) data has enabled a detailed interpretation of subsurface features. The vertically elongated high-density anomalies beneath lava domes located near Wakoto Peninsula and Mt. Atosanupuri are interpreted as subsurface intrusive bodies, while low-density anomalous feature to the depth represents the Kutcharo caldera structure, which was filled with large scale of low-density pyroclastic materials. Helitem^® electromagnetic data acquired in combination with the AGG data revealed a widespread conductive anomaly west of Mt. Atosanupuri, which may represent the cap rocks to a geothermal reservoir. The distribution of a low magnetic intensity zone matches that of a low-resistivity zone, suggesting that magnetite degradation and demagnetization possibly occur, most likely caused by hydrothermal activities. Integrated interpretation of airborne gravity gradiometer, electromagnetic and magnetic data helps with identification of prospective areas and planning of a drilling program for the development of geothermal energy with greater precision.

Teshikaga地区内的地热勘探已采用了多种地球物理技术。HeliFalcon的三维反转^®航空重力梯度测量（AGG）数据已使地下特征的详细解释。Wakoto半岛和富士山附近熔岩穹顶下方垂直延伸的高密度异常。Atosanupuri被解释为地下侵入体，而在深度上的低密度异常特征则代表了Kutcharo破火山口结构，其中充斥着大规模的低密度热碎屑材料。Helitem ^®结合AGG数据获得的电磁数据显示了Mt.Mt西面的一个广泛的导电异常。Atosanupuri，可能代表了地热储层的盖岩。低磁强度区的分布与低电阻率区的分布相匹配，这表明可能发生磁铁矿退化和退磁，这很可能是由热液活动引起的。机载重力梯度仪，电磁数据的综合解释有助于确定潜在区域并规划钻井计划，以开发更高精度的地热能。
