Subsidence, as a geophysical phenomenon, refers to the downward vertical displacement or gradual sinking of the Earth’s surface relative to a reference datum, driven by processes that reduce support in the underlying materials. Mechanisms include natural compaction of sediments, dissolution of soluble rocks (e.g., karst), tectonic extension, crustal loading and unloading, and anthropogenic drivers such as groundwater, hydrocarbons, or geothermal fluid extraction, as well as mining-induced void creation. Subsidence is quantified using geodetic and remote sensing techniques (e.g., GNSS, InSAR) and significantly influences stress fields, surface drainage, infrastructure stability, and hazard assessment in both natural and urban environments.
Around a quarter of the U.S. food supply is grown in California's Central Valley. Most of its crops, like rice, fruit trees and nut trees, are water-intensive and require extensive groundwater pumping during droughts. Over ...

As seismic waves travel through Earth, they gradually lose energy, a process called attenuation. That energy loss doesn't happen uniformly—some features in the crust sap far more energy from seismic waves than others. Researchers ...
