| Research Abstract |
To determine in-situ stress states in scientific active-fault deep drilling projects and to develop stress measurement techniques in deep ocean drillings, we determined the stress orientation distribution in the southwest Japan subduction zone in an ocean drilling project "Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE)" and found a stress anomaly cased by fault rupturing during the 1999 Taiwan Chi-Chi earthquake in "Taiwan Chelungpu-fault Drilling Project (TCDP)". At the same time, we successfully applied a core-based method called anelastic strain recovery (ASR) method to deep ocean drillings.
