| 内容記述 | To understand the physical bases of earthquake generation along subducting plate boundaries, it is important to know the physical properties of rocks, asperity distribution, and presence of water at the plate interface. Two seismic experiments in the Japan Trench and the Izu-Bonin Trench revealed a strong correlation for aseismic zone and intense seismic reflections, and the possibility of a low-temperature phase of serpentine at subducting plate boundaries. Serpentine layer or high water contents in the layer may cause intense seismic reflections. Free water and/or low- temperature serpentine mineral may act as a lubricant at the subducting plate boundary, and large earthquakes may be controlled by the presence of these materials. We propose three types of subduction zone around the Japan arc and the Izu-Bonin arc to characterize earthquake generation in each subduction zone. Earthquake occurrence in three typical subduction zones may be controlled by differences in the free water contents of rocks and hydrous minerals along subduction boundaries. Dehydration of hydrous phases brings other conditions related to earthquake generation. | |||||
