[M-IS08] Interdisciplinary studies on pre-earthquake processes

Sun. Jun 6, 2021 1:45 PM - 3:15 PM Ch.22 (Zoom Room 22)

convener:Katsumi Hattori(Department of Earth Sciences, Graduate School of Science, Chiba University), Dimitar Ouzounov(Center of Excellence in Earth Systems Modeling & Observations (CEESMO) , Schmid College of Science & Technology Chapman University, Orange, California, USA), Jann-Yenq LIU(Department of Space Science and Engineering, National Central University, Taiwan), Qinghua Huang(Peking University), Chairperson:Peng Han(Southern University of Science and Technology, Shenzhen, China), Xuemin Zhang(Institute of Earthquake Forecasting, China Earthquake Administration)

The year 2021 is the memorial year of the 2011 Tohoku Earthquake (M9.0). For the past decade, we have advanced our knowledge of precursors and earthquake preparation processes.
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, enhancing a better understanding of the tectonic activity. The session anticipates talks that include but is 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 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.
