[S-SS06] Fault Rheology and Earthquake Physics

Tue. May 23, 2023 10:45 AM - 12:00 PM 302 (International Conference Hall, Makuhari Messe)

convener:Michiyo Sawai(Chiba University), Shunya Kaneki(AIST), Ryo Okuwaki(University of Tsukuba), Yumi Urata(National Institute of Advanced Industrial Science and Technology), Chairperson:Shunya Kaneki(Disaster Prevention Research Institute, Kyoto University), Yumi Urata(National Institute of Advanced Industrial Science and Technology)

The goal of this session is to integrate theoretical, experimental, observational, and numerical perspectives from various fields such as seismology, geodesy, geology, mineralogy, and so on, to define what is known about earthquake source processes and the physical and chemical elementary processes of faulting. This session welcomes studies that address such issues as pre-, co-, and post-seismic processes, the rheology of seismogenic faults and fault rocks, laboratory experiments on elementary processes, numerical models based on frictional laws, and estimates of the stress field in the seismogenic zones. We also welcome studies on fault-zone drilling projects and in situ stress measurements.
