| | Abstract | | After the Great East Japan Earthquake in March 2011, development of a geothermal energy is gathering attention. Although gravity method is generally used in geothermal exploration, we focused on the airborne electromagnetic method because of its ability to detect fault structure and resistivity distribution. An application of 3-D forward modeling of airborne TEM (transient electromagnetic) method for wide survey of geothermal area is presented in this paper. A low resistivity anomaly is set in the homogeneous subsurface as a geothermal reservoir. The calculation result of the simulation showed the highest negative anomaly above the center of the low resistivity anomalous body. These results proved that geothermal reservoir can be detected by airborne TEM method. |
