[S-SS30] Earthquake Source Processes and Physics of Earthquakes

Mon. May 25, 2015 2:15 PM - 4:00 PM A05 (APA HOTEL&RESORT TOKYO BAY MAKUHARI)

Convener:*Ryosuke Ando(Graduate School of Science, University of Tokyo), Yuko Kase(Active Fault and Earthquake Research Center, AIST, GSJ), Chair:Bogdan Enescu(筑波大学大学院生命環境科学研究科　), Takahiko Uchide(Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology)

The goal of this session is to integrate theoretical, experimental, and observational perspectives to define what is known about earthquake source processes. We solicit submissions that address such issues as pre-, co-, and post-seismic processes, earthquake cycles, laboratory experiments on elementary processes, numerical models based on frictional laws, estimates of in situ stress field.
