Outline of Final Research Achievements |
The objective of this project is to understand the process of intermediate-depth and deep-focus earthquakes from the viewpoint of mineral physics. To evaluate the semi-brittle behavior of slab-forming rocks (i.e., harzburgite), acoustic emission monitoring is essential as well as measurements on strain and stress at high pressures and high temperatures. Such experimental techniques have been developed by Schubnel et al. (2013), who belong to a French-USA international research group. Our measurement system is now applicable to the semi-brittle behavior of rocks as well as the Schubnel's system. Using our measurement system, axial compression experiments on rocks are possible at high pressures and temperatures. Thus, the process of rock failure will be clarified by our group.
