Abstract
The automatic interpretation of apparent resistivity curves from horizontally layered earth models is carried out by the curve fitting method of three steps: (1) the observed VES data are interpolated at equidistant points of electrode separations on the logarithmic scale by using the cubic spline function, (2) the layer parameters which are resistivity's and depths are predicted from the sampled apparent resistivity values by SALS system program and (3) the theoretical VES curves from the models are calculated by the Ghosh's linear filter method using Zhody's computer program. Two sounding taken over Takenoyu geothermal area were chosen to test the procedures of the automatic interpretation.
