This session is dedicated to the integrated monitoring of active faults through multi-parameter networks and Near-Fault Observatories (NFOs), with the goal of improving our understanding of crustal deformation processes, fault mechanics, and the seismic cycle in near-source environments. We welcome contributions that combine high-resolution seismic monitoring (dense local networks, temporary deployments, microseismicity and repeating earthquakes) with geodetic, geophysical, and hydrogeochemical observations (GNSS, InSAR, strainmeters, tiltmeters, borehole sensors, fiber-optic sensing, groundwater level and temperature, geochemical tracers and gas emissions) to investigate fault behavior across a wide range of temporal scales, from slow deformation and fluid migration to earthquake nucleation and rupture.Particular emphasis is placed on studies based on continuous, long-term observations of well-instrumented fault systems, highlighting how integrated near-fault datasets provide key constraints on stress accumulation, fault zone properties, fluid–fault interactions, and deformation partitioning. Contributions addressing methodological advances, observatory design, and cross-disciplinary data integration are also encouraged. Relevant topics include:
- Near-Fault Observatories and integrated multi-parameter monitoring strategies for active faults;
- microseismicity, fault zone structure, and seismic clustering in near-source regions;
- joint seismic–geodetic–hydrogeochemical observations of crustal deformation and fluid processes;
- slow deformation, fluid-driven processes, and transitions between aseismic and seismic behavior;
- observational constraints on physical models of fault mechanics, fluid–fault interactions, and the seismic cycle.
The session aims to promote the exchange of experiences from different tectonic settings and to strengthen the link between observational infrastructures and process-oriented studies of active fault systems.
