[S-SS06] [EE] From Earthquake Source and Seismicity Parameters to Fault Properties and Strong-motion Assessment

Wed. May 24, 2017 3:30 PM - 5:00 PM Poster Hall (International Exhibition Hall HALL7)

convener:Takahiko Uchide(Research Institute of Earthquake and Volcano Geology, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology (AIST)), Bogdan Enescu(Department of Geophysics, Kyoto University), Hiroki Sone(University of Wisconsin-Madison)

Recent development of seismic networks has expanded our capability to study the characteristics of individual earthquake sources and seismicity. Those characteristics will be clues to enhance our understanding of fault properties and hence the characteristics of future earthquakes and resultant strong motion. These studies are feasible even during the interseismic period, since small earthquakes occur much more frequently than large ones. Recent advances in data analysis methods have also contributed to reduce uncertainties and bias in the earthquake parameters.

We would like this session to be a good opportunity to share recent updates of studies of earthquake parameters: macroscopic source parameters (e.g., stress drop, radiated energy, moment tensor, and magnitude) and seismicity parameters (e.g., b-values of Gutenberg-Richter's law, ETAS parameters). Comparisons between finite fault models of large earthquakes and earthquake parameters of collocated small earthquakes are also within the scope of this session. We also invite contributions investigating the source physics behind earthquake parameters by, for example, numerical simulation and laboratory experiments, and studies applying earthquake parameters for strong-motion assessment.
