A major cause of land subsidence is the removal or disturbance of groundwater in soil and between rocks and sand found underground. Because subsidence often makes areas uninhabitable, these conditions can cause water and food insecurity, and potential political issues. To help investigate solutions, researchers are using satellite radar altimetry with creative new techniques to understand how Earth’s complex geophysical processes impact human life.
