[M-IS04] Interdisciplinary studies on pre-earthquake processes

Sun. May 26, 2024 1:45 PM - 3:00 PM 301B (International Conference Hall, Makuhari Messe)

convener:Katsumi Hattori(Department of Earth Sciences, Graduate School of Science, Chiba University), Jann-Yenq LIU(Center for Astronautical Physics and Engineering, National Central University, Taiwan), Dimitar Ouzounov(Chapman University), Qinghua Huang(Peking University), Chairperson:Katsumi Hattori(Department of Earth Sciences, Graduate School of Science, Chiba University), Peng Han(Southern University of Science and Technology, Shenzhen, China)

We have learned a lot about precursors and earthquake preparation. This session expands the interdisciplinary discussions on the preparation process of earthquake and earthquake predictability by presenting the latest progress in studying the physically based pre-earthquake phenomena. New observations from space and ground have provided evidence that may enhance a better understanding of tectonic activity. The session anticipates talks that include but are not limited to observations and analyses of seismic, electrical, electromagnetic, electro-chemical and thermodynamic processes related to stress changes in the lithosphere, along with their statistical and physical validation. Presentations on the latest observational results associated with major earthquakes obtained by different methodologies are welcomed. The topics of the session are as follows but not limited.

-General discussion on the earthquake preparation process and the physics of pre-earthquake signals
- Theory, modeling, laboratory experiments, computational simulation for generation and propagation of pre-earthquake signals and their connection with the seismic cycle
- Multi-parameter observations, detection, and validation of pre-earthquake signals
- Cross-disciplinary studies, practical and technical approaches for better understanding of earthquake preparation processes and their connection with seismicity.
