| Research Abstract |
Mode of energy dissipation by an large earthquake is examined by using drilled core penetrating the Chelung-pu Fault, being activated by 1996 Chi-chi earthquake, Taiwan. Total dissipated energy was simply assumed as sum of heat energy by friction and fracture energy by pulverization of mineral grains contained in the slip zone. Progress of analysis clarified, however, chemical process, such as dissolution-precipitation is dominantly activated by grain comminution. Dynamic chemical process activated by reaction between intra-slip zone fluid and comminuted grains is an as-yet-unrecognized factor. We are trying to solve chemical process during seismic slip.
