CORRECTION: The massive Central Valley subsidence: is Actually a LOT Worse Than 10 Feet!

CORRECTION: The massive Central Valley subsidence: is Actually a LOT Worse Than 10 Feet! Yesterday’s Daily Data had the right number in mind but the wrong graphic.

The NASA subsidence image used yesterday was only for eight months: May 2014-January 2015.

Actually, the worst subsidence measured was for 1926-1977 and about 28 feet  (more than 8.5 meters). See photo below map for a human-eye view. A ten-foot subsidence would be a hair over 3 meters. See this page for a shocking photo and more data from the U.S. Geological Survey.

And from another perspective. Look at the top of the photo for where the surface was in 1925

Approximate location of maximum subsidence in the U.S., identified by research efforts of Dr. Joseph F. Poland (pictured). Signs on pole show approximate altitude of land surface in 1925, 1955, and 1977. The site is in the San Joaquin Valley southwest of Mendota, CA. See USGS Land Subsidence Monitoring Network for more.
