Geothermal Resource Exploration in Magmatic Rock Areas Using a Comprehensive Geophysical Method

Figure 3

Comparison of the underground current distribution stimulated by the ground wire source and the loop source in a uniform half space; the left diagram is simulated by using a ground wire source, whereas the right diagram is simulated by using a loop source. (E)1 represents horizontal current, (E)2 represents vertical induced current, and (H)1 represents vertical magnetic field.
