[M-IS09] Interdisciplinary studies on pre-earthquake processes

Sun. May 25, 2025 5:15 PM - 7:15 PM Poster Hall (Exhibition Hall 7&8, 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)

This session summarizes a multi-year research effort on precursors and earthquake preparation processes. We expand the interdisciplinary discussion on earthquake predictability by presenting the latest progress in studying the physically based pre-earthquake phenomena. New observations from space and ground have provided new evidence, which may enhance 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 to:

-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.
- AI or machine learning approach to earthquake forecast.
