Additional Information ideas
We could add a section outlining the data that was found relating to the subsidence located in the Merced and Fresno areas as mentioned in the articles below. It would help connect this article to other sources such as GPS, InSAR, etc.

The second article has some more information of subsidence data through the use of extensometers. Could have more useful information to support the importance and general use of an extensometer in relation to groundwater compaction.

The third source has some general information that I believe could be added. The portion where it mentions how many were made and what years (like a timeline) they were constructed could be useful.
