Ground deformation refers to changes in the shape or elevation of the Earth's surface caused by various natural processes, such as volcanic activity, tectonic plate movement, or groundwater extraction. It can manifest as subsidence (sinking of the ground) or uplift (rising of the ground) and may pose risks to infrastructure and the environment. Monitoring and studying ground deformation are crucial for understanding geological processes and mitigating hazards.
Increased seismic activity such as earthquakes. Eruption of lava, ash, and gases. Ground deformation or changes in ground temperature.
Deformation associated with earthquakes is measured using a combination of methods, including seismometers, GPS geodesy, and satellite imagery. Seismometers detect ground shaking during an earthquake, while GPS geodesy provides precise measurements of ground displacement over time. Satellite imagery, particularly from synthetic aperture radar (SAR), can capture surface deformation before and after seismic events. Together, these methods offer a comprehensive understanding of tectonic movements and the deformation patterns associated with earthquakes.
Deformation is a change in the shape or size of a material due to stress or strain. It can be caused by external forces such as pressure, tension, or shearing forces acting on the material, leading to a rearrangement of its atomic structure. Deformation can result in a temporary change (elastic deformation) or a permanent change (plastic deformation) in the material.
Anelastic deformation is a type of deformation in materials where they exhibit some degree of recovery after the stress is removed, similar to elastic deformation. However, anelastic deformation involves some permanent rearrangement of the material's structure, causing it to not return completely to its original shape. This behavior is typically seen in materials like polymers and some metals.
There are generally three main types of deformation: elastic, plastic, and brittle. Elastic deformation occurs when a material returns to its original shape after the stress is removed. Plastic deformation involves a permanent change in shape due to applied stress, while brittle deformation leads to fracture without significant deformation. Each type responds differently to stress and strain depending on the material properties and environmental conditions.

it is deformation below recrystalization temperature.
Two kinds of deformation are plastic deformation, where the material changes shape permanently due to stress, and elastic deformation, where the material returns to its original shape after stress is removed.
Elastic deformation is recoverable deformation. As such, when the load that caused the deformation is removed the material will return to it's original shape.
Elastic deformation is the temporary distortion experienced by a material under stress, where the material returns to its original shape once the stress is removed. This deformation is reversible and does not cause permanent changes to the material's structure.

Brittle objects typically do not undergo plastic deformation due to their inability to sustain significant deformation before fracturing. Instead, brittle materials tend to fracture with minimal or no plastic deformation.
