Recently, a geological survey was conducted in the desert of Arizona and during the survey, the drone used found a roughly 2-mile long crack. While it isn’t the first crevice to form in the area, it certainly is the longest.
The Arizona Geological Survey estimates that the fissure started forming in 2014 after heavy rainfall but that the southern half of the fissure seems to be newer (perhaps as recent as 2016).
The Arizona Geological Survey says:
“Earth fissures are tension cracks that open as the result of subsidence due to severe overdrafts (i.e., pumping) of groundwater. As the ground slowly settles, cracks form at depth and propagate towards the surface, hundreds of feet above. Individual fissures range in length from hundreds of feet to several miles, and from less than an inch to several feet wide. Rainstorms can erode fissure walls rapidly causing them to widen and lengthen suddenly, and dangerously, to form gullies 5- to 15- ft wide and tens of feet deep.”
When will we learn that what we do to the earth HAS actual effects on the environment? When will we understand that our actions have actual consequences?
