微小岩石破壊から巨大地震まで適用可能な地震発生物理学の構築

抄録

This manuscript summarizes studies on earthquake source physics by the author, with some explanations of the influence of very large earthquakes in this study field. The author has been working on the whole generation process of earthquakes, from tiny rock failure to mega-earthquakes, mainly using seismic data analysis, also based on elasto-mechanics, fracture criterions, and friction laws. These studies confirmed that earthquakes are characterized by wide scale range, without limitation of specific sizes. There is little difference in the initial processes of dynamic rupture of micro and mega earthquakes. Numerical models for such wide-scale phenomena may require some hierarchal structures, which are also essential to make any prediction and forecast for future earthquakes. The knowledge for earthquake generation must be also utilized to understand other phenomena governed by power laws.
