Interferometric Synthetic Aperture Radar (InSAR) is a remote sensing technique that uses radar signals to generate precise maps of land surface deformation over time. By capturing multiple radar images from slightly different positions, it can measure ground movements with millimeter-level accuracy, making it invaluable for monitoring earthquakes, volcanic activity, and subsidence.

Volcanic activity encompasses the processes and phenomena associated with the eruption of magma, gases, and ash from beneath the Earth's crust to its surface, often forming volcanic landforms. It plays a crucial role in shaping the Earth's landscape, influencing climate, and impacting ecosystems and human societies through both constructive and destructive events.

Volcanic Activity

Subsidence is the gradual sinking or settling of the Earth's surface, often due to natural processes like the compaction of soil or human activities such as groundwater extraction. It can lead to significant infrastructure damage, increased flood risk, and environmental impacts, necessitating careful monitoring and management strategies.
