[S-CG40] Science of slow-to-fast earthquakes

Tue. May 28, 2024 5:15 PM - 6:45 PM Poster Hall (Exhibition Hall 6, Makuhari Messe)

convener:Aitaro Kato(Earthquake Research Institute, the University of Tokyo), Asuka Yamaguchi(Atomosphere and Ocean Research Institute, The University of Tokyo), Yohei Hamada(Japan Agency for Marine-Earth Science and Technology), Akemi Noda(Meteorological Research Institute, Japan Meteorological Agency)

Growing evidence of geophysical observations has demonstrated that earthquake faults host a broad spectrum of slip modes from slow to unstable fast slip, which may lead to complexity in the nucleation process, rupture behavior, and slip & energy distribution. This discovery has boosted up vigorous discussions about the connection between slow and fast earthquakes including large earthquakes. How and when does a slow earthquake become a fast earthquake? To answer this fundamental question, it is particularly important to proceed further interdisciplinary research through the integration of geophysics, seismology, geodesy, geology, and physics. Developments of measurement technology, application of information science and statistical methods to seismic big-data and utilization of high-performance computing are required as key ingredients in accelerating the integration. This session encourages presentations shedding light on geophysical observations, data analysis, field studies, laboratory experiments, numerical modeling, and theoretical studies. We also welcome contributions from cutting-edge science and technology fields that explore development of novel measurements, data-driven analysis, and large-scale computation etc., those are relevant to slow and fast earthquakes.
