Quantitative evaluation of energy taken up by coseismic chemical reaction

点击翻译按钮获取中文摘要

Because determination of the energy budget is key to understanding the physics of earthquakes, quantitative evaluation of the energy taken up by coseismic chemical reaction is important. I performed chemical analysis of fault-rock sample from natural seismogenic faults, and revealed the signals indicating the coseismic reaction were found. By a numerical analysis incorporating thermal property measurement, chemical kinetics, and energy conservation, I evaluated the energy taken up by the reaction.
