Outline of Final Research Achievements |
To investigate the relationship between behavior of seismic fault slipping and stress state in the vicinity of the fault and in the wall rocks, we conducted stress measurements in the ocean scientific drilling project JFAST penetrated into the plate boundary fault which ruptured during the 2011 Tohoku earthquake, and also developed the relative stress measurement techniques. As their results, we obtained the stress profile in the JFAST borehole, and the results enabled us to compare with the stress state spatial distribution in the Nankai Trough subduction zone where is the source region of the Tonankai and Nankai earthquakes. In addition, we determined the three heat transfer properties using the JFAST core samples, and contributed the interpretation on the temperature anomaly detected at depth around the plate boundary in the JFAST borehole.
