| Session Description | Recently, a series of unusual earthquake phenomena is under investigation like slow earthquake, these are earthquake like event that releases energy over a period of hours to months, rather than the seconds to minutes characteristic of a typical earthquake. This unusual earthquake phenomenon includes deep episodic tremor, low-frequency earthquakes, very-low-frequency earthquakes and slow slip events. Each of these has been demonstrated to arise from shear slip, just as do regular earthquakes, but with longer characteristic durations and radiating much less seismic energy. Slow seismic events may be useful for better understanding of the plate subduction process and large earthquake generation. In this session, we welcome papers on slow earthquakes. During the fast earthquakes now various necessary information on the kinematics and dynamics of earthquakes are available. In many recent large earthquakes such information includes slip evolution, frictional properties during faulting, fault system geometry and the structure of fault zones. This provides the fundamental knowledge base with which to build an ‘earthquake mechanism’ capable of simulating the earthquake generation process and cycles of earthquake activity. In this session, we welcome papers earthquake simulation models as well as aiming to provide insight on the kinematics and dynamics of earthquake generation and cycles. Seismic waves generated by earthquakes have been interpreted to provide us information about the earth’s structure across a variety of scales. Seismic tomography is promising tool to evolve various heterogeneous structure. In this session, we welcome papers on evolving earth’s structure. |
