A volcanologist observes that the ground deformation at a monitoring site increased by 12.5 cm over 50 days, measured using satellite radar interferometry. If the uplift rate remains constant, how many centimeters of deformation would be recorded after 180 days?

**The Ground Shifts Beneath Us: What Scientists Observe and What It Reveals** When a volcanologist notices a 12.5 centimeter uplift at a monitoring site over 50 days, measured via satellite radar techniques, it marks more than a technical observation—it’s a window into Earth’s restless processes. This gradual rise in ground level, detected with precision and reliability, speaks to shifting magma beneath the surface, driving subtle yet measurable changes in the crust. As satellite monitoring improves, such data becomes increasingly accessible, sparking widespread interest in how volcanoes respond to subtle pressure and movement. This trend resonates across scientific communities and broader audiences in the U.S., as growing awareness of natural hazards and climate-linked environmental changes fuels curiosity about Earth’s inner workings. **Why this uplift matters now**
In recent years, interest in ground deformation at volcanoes has surged, driven by heightened public awareness of geological risks and advancements in remote sensing technology. Regions with active volcanism—though scattered across the American landscape—now benefit from real-time monitoring systems that detect changes invisible to the human eye. The consistent increase in ground elevation over 50 days reflects natural tectonic forces, not immediate danger, but offers critical
