"Further inland in California’s Central Valley, excessive pumping of groundwater for agriculture has caused the land to sink significantly. Since the 1920s, sections of the San Joaquin Valley have sunk by as much as 8.5 meters (28 feet). Groundwater pumping becomes even more problematic during droughts, exacerbating subsidence problems. Data from 2015 showed some spots subsided at rates as high as 600 millimeters (2 feet) per year." https://www.washingtonpost.com/climate-environment/2023/05/30/land-sinking-us-subsidence-sea-level/ https://www.washingtonpost.com/climate-environment/2023/05/3...
