Understanding earthquake source processes requires identifying robust, quantitative factors shared among earthquakes, such as the roles of fault geometry and stress distribution in rupture dynamics, fluid effects over a wide spectrum of faulting behavior, and the energy budget across scales. Insights from geological, seismological, and geodetic observations provide key constraints for quantitative interpretations and modeling of earthquake source processes. Furthermore, clarifying the statistical properties of these quantitative descriptions, such as variability and trade-offs among model parameters, is essential for establishing their generality across natural earthquakes in diverse tectonic settings.

This session aims to advance our understanding of earthquake source processes by focusing on identifying, quantifying, and validating such robust factors through this integrated framework. We welcome studies using any approach toward this goal, including analyses of earthquake catalogs enhanced by ML and DAS, geological observations, numerical modeling, and both small- and large-scale laboratory experiments on earthquake ruptures.
