日本列島における地震発生メカニズムに関する研究 Earthquake Occurrence Mechanism in the Japanese Islands
At present, a slow earthquake is continuing in the Tokai area. Then, the energy of approximately magnitude of 7.2 is estimated to have released. However, it doesn't find whether or not this slow earthquake develops into the big earthquake. This slow earthquake is supposed to have occurred because a part of the Philippin sea plate comes off. As the result, the extraordinary crustal movement in the Tokai district has been clarified from the GPS observation result. Moreover, recently, the extraordinary crustal movement has occurred in the wide area including Kanto and the central area. In this research, An analysis to clarify the occurrence mechanism of the earthquake in the Japanese Islands was progressed and the movement of the tectonic line in the Japanese Islands was clarified.
