Research Abstract

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.
