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 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."
What's more, this furious groundwater pumping could have long-term consequences. If the land shrinks too much, and for too long, it can permanently lose its ability to store groundwater.
The state's sinking isn't new: California has long suffered from subsidence, and some parts are now a few dozen feet lower than they were in 1925, according to the U.S. Geological Survey.If fracking requires fresh water, it ain't gonna happen in California.
