Session ID#: 13507

Session Description:
Macroscopic earthquake source parameters (in a broad sense; e.g., stress drop, radiated energy, moment tensor, and magnitude) from seismic data reflect physics of fault rupture process and fault properties such as stress on the fault and fault strength. Consequently the source parameters are useful for investigating rupture process and fault properties, and hence assessing earthquake hazard. Modern seismic networks enable us to analyze large number of earthquakes and study their spatial and/or temporal trends. To further promote this research, we need both accurate estimations of source parameters and appropriate interpretation. This session aims to expand the capability of earthquake source parameter studies to give us better knowledge on, for example, earthquake rupture dynamics, fault properties, tectonics, and seismic hazard assessment. We welcome theoretical, numerical, observational, and experimental contributions to improve the estimation and interpretation of source parameters.
