Microseismic monitoring has become an important tool for characterizing rock-mass failure, fracture development, fluid-driven deformation, and fault activation in geo-engineering and subsurface energy operations. This Special Issue aims to present recent advances in microseismic acquisition, processing, imaging, interpretation, and integrated geomechanical analysis, with emphasis on both methodological innovation and field-scale applications. Topics of interest include dense and distributed sensing, passive seismic detection, event association, source location and characterization, seismic imaging and inversion, wave-equation-based methods, numerical modeling of elastic and viscoelastic wavefields, machine learning, uncertainty assessment, and real-time monitoring. Applications may cover underground engineering stability and rockburst warning, hydraulic fracturing, oil and gas reservoir monitoring, geothermal development, induced seismicity, carbon dioxide geological sequestration, underground energy storage, reservoir and dam safety, and fault activity. Contributions that integrate microseismic observations with geomechanics, fiber-optic sensing, laboratory experiments, or multiphysics modeling are particularly welcome. The Special Issue seeks to bridge fundamental developments and practical monitoring needs, providing a forum for robust, scalable, and interpretable approaches to subsurface characterization and risk assessment. Original research papers and representative case studies that demonstrate advances in monitoring resolution, reliability, automation, and engineering decision support are encouraged.
