Description: An increasing number of continent earthquakes indicate that major earthquakes primarily occur along boundary tectonic zones. Therefore, understanding the deformation of these tectonic zones and fault movements is an important foundation for recognizing the patterns of earthquake generation. With the application of modern advanced technologies, the precision and resolution of data from topographic surveys, geophysical investigations, and dating methods have significantly improved, providing more reliable information and new perspectives for studying tectonic zone deformation and fault movements. This session focuses on the research of tectonic zone deformation, deep structure, and the relationship between fault movements and earthquake generation patterns. We welcome colleagues to present new methods, data, and insights to jointly discuss and deepen our understanding of scientific issues related to the mechanisms of tectonic zone deformation, fault movements, and earthquake generation patterns.

Description: Large earthquakes within plate interiors, although less common than earthquakes at plate boundaries, have killed more people than interplate earthquakes. Large intraplate earthquakes have occurred in mainland China and other parts of the world, such as Australia, the central and eastern United States, and continental Europe. This session explores seismicity and seismogenic sources, and their connection to crustal and mantle structure. This session aims to promote the sharing of new interdisciplinary data and results to help elucidate the deep structure, mechanisms and processes of moderate-to-strong earthquakes within plate interior. We encourage studies from multiple disciplines, including, but not limited to, geology, geophysics, geodesy and geodynamics.

Description: The mechanism of strong earthquake is always an important frontier scientific problem pursued by seismologists. In recent years, with the progress of new observation techniques and theories, such as high-density network, deep well observation and optical fiber sensing, scientists have more data support and new perspectives on the understanding of the occurrence process of strong earthquakes. The study gradually revealed the diversity of earthquake nucleation and rupture modes, such as pre-slip versus cascade phenomena, and subshear versus supershear rupture. Meanwhile, with big data and lessons learned from recent earthquakes, there is an ongoing progress of physics-based earthquake source models, providing reasonable estimates of the magnitude and likelihood of earthquake rupture. This session welcomes presentations on all aspects of these exciting frontier research areas.

Description: Accurate earthquake risk assessment is the foundation for the effectiveness of operational earthquake defensive measures, which demands quantitative and refined forecast of strong earthquakes. Mid-long term probabilistic forecast and numerical forecast of earthquakes can satisfy the requirements. With the development of earthquake observation and exploration, theory and technology, the physical model of the earthquake source has gradually improved, the mechanism of strong earthquake propagation became clearer, and numerical simulation technology of the dynamic process of strong earthquake propagation has gradually matured. The mid-long term probabilistic forecast and numerical forecast of earthquakes have preliminary scientific, model, technical, computational and data conditions. This section is focused on, but not limited to, the theory, methods, and practices of mid-long term probabilistic forecast and numerical forecast of earthquakes. Special attention is paid to the establishment of comprehensive probability models for earthquakes, the scientific understanding and numerical simulation of dynamic effects at different scales during the process of strong earthquake preparation and occurrence, and the numerical simulation of in-situ recurrence of strong earthquakes.

Description: Whether there exist earthquake precursors for earthquake forecasting" is one of 125 scientific questions raised by Nature in 2005 that need to be addressed in the coming decades. The nearly 50 years of earthquake prediction practice in China has shown that obvious earthquake precursory anomalies do exist before strong earthquakes. However, the identification of earthquake precursory anomaly is still extremely difficult. In detection of earthquake precursory anomaly, all of the non-tectonic factors affecting the observation need to be excluded firstly. Meanwhile, the abnormal change of the observation data needs to be explained by the related seismogenic process. This session focuses on but not limited to using various data analysis, numerical simulation, model building and other methods to explore the identification methods and techniques of various observations, as well as the possible physical mechanism of pre-earthquake anomalies.

It is hoped to significantly enhance the technical readiness level (TRL) of the existing methods of OEF and SHA - the empirical, the statistical, the physics-based, and the numerical, making earthquake forecast and SHA more contributive to the society for disaster risk reduction (DRR). Roles of test sites for earthquake forecast and sociological problems associate with OEF and SHA are also taken into consideration.

Description: Earthquake forecast is a practice-oriented problem crossing the border of natural science, engineering, and social sciences. This character had been recognized shortly after the Haicheng earthquake by the disciplines of seismo-sociology and earthquake countermeasures. Planning the systems engineering of earthquake forecast at the national and global scales plays an important role for future developments. In this regard different countries/regions have accumulated rich experiences and lessons which are in need of further exchange, discussion, systemization and formulation.
