GroundMoving

GroundMoving refers to the movement and deformation of the ground surface and near-surface layers caused by external forces. It covers rapid motion from seismic shaking as well as slow deformation from processes like settlement, creep, and landslides. Researchers quantify GroundMoving by tracking displacement, velocity, and acceleration over time using a range of sensors and imaging techniques.

Causes are natural and anthropogenic. Natural causes include earthquakes, landslides, soil liquefaction, frost heave, permafrost thaw, and volcanic activity. Human activities such as excavation, mining, heavy loading, groundwater withdrawal, and reservoir-induced changes can also drive GroundMoving. The timescales span from seconds during earthquakes to days, months, or years for gradual movement or settlement.

Measurement and analysis rely on multiple methods. Seismic networks and GNSS receivers capture rapid and long-term motions, while InSAR and tiltmeters provide spatially resolved deformation data. GroundMoving is analyzed with geotechnical and geophysical models to predict responses of soils, rocks, and engineered structures, including elastoplastic behavior and dynamic soil-structure interaction.

Applications and implications include informing building codes, infrastructure design, and disaster preparedness. Monitoring GroundMoving supports maintenance planning for roads, railways, and foundations, and guides land-use decisions in prone areas. Mitigation strategies focus on proper foundation design, slope stabilization, drainage management, controlled compaction, and strategic avoidance of high-risk zones.
