| Scope |
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 and 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? What geological and geophysical structural differences distinguish slow earthquakes from fast ones? To answer these fundamental questions, it is particularly important to proceed further global and interdisciplinary research through the integration of geophysics, seismology, geodesy, geology, and physics. Advancements in measurement technology, the application of information science and statistical methods to seismic big data, and the utilization of high-performance computing are required as key ingredients in accelerating the integration. In addition, various subduction zone phenomena, including earthquakes, volcanic eruptions, and surface processes , often occur as a cascading series of events, necessitating a system-wide, integrative approach. This session encourages presentations shedding light on geophysical observations, data analysis, field studies, laboratory experiments, numerical modeling, and theoretical studies, as well as comparative investigations across onshore fault zones and multiple subduction systems. We also welcome contributions from cutting-edge science and technology fields that explore development of novel measurements, data-driven analysis, and large-scale computation that are relevant to our understanding of slow and fast earthquakes and other subduction zone phenomena. This session is organized by the JpGU Science of Slow and Fast Earthquake Focus Group and the SZ4D initiative.
