And this is from 2016
Since the 1920s, excessive pumping of groundwater at thousands of wells has caused land to subside, or sink, by as much as 8.5 meters (28 feet) in sections of California’s San Joaquin Valley
Several trouble spots that were identified in 2015 have continued to subside at rates as high as 0.6 meters (2 feet) per year. |
Well, the whole valley was covered in water at one point in history. I have a shark's tooth that was supposedly recovered at an oil well site. It only makes sense when I remember the number of long gone relatives that worked the oil patch back during WWII and even before that. IIRC, the production in the San Joaquin was ramped up during the war.
Maybe when the seas rises and the land sinks, that new waterfront property in CA everyone talks about when the coastline falls into the sea after the "Big One," actually takes another form.
