An “8-element-gauge” method is one of the stress relief techniques for the in situ stress measurements. Using this method, the measurements have been carried out at twelve sites by the Research Group for Crustal Stress in Western Japan. During the in situ processes and the data analyses for these measurements, many problems have been encountered. These problems were investigated in detail and important ones were settled. Hence the “8-element-gauge” method was significantly improved. Based on the results of the investigations, the stress values were revised into more reliable ones. In addition, characteristics of this method were examined in detail. The examinations show that the stress values are unavoidably affected by systematic errors associated with distinctive eigen vectors of the Jacobian matrix of the observation equation, unless certain conditions, such as properties of rocks, are satisfied. They also show that the stress values for several sites are suspected to include considerable amount of these errors.
