California Sinking Faster Than Thought, Aquifers Could Permanently Shrink
California is sinking even faster than scientists had thought, new NASA satellite imagery shows.
Some areas of the Golden State are sinking more than 2 inches (5.1 centimeters) per month, the imagery reveals. Though the sinking, called subsidence, has long been a problem in California, the rate is accelerating because the state's extreme drought is fueling voracious groundwater pumping.
"Because of increased pumping, groundwater levels are reaching record lows — up to 100 feet (30 meters) lower than previous records," Mark Cowin, director of California's Department of Water Resources, said in a statement. "As extensive groundwater pumping continues, the land is sinking more rapidly, and this puts nearby infrastructure at greater risk of costly damage." [It's Raining Spiders!
