A massive Two-mile crack is found
in the Arizona desert, as Giant fissure in the earth is spotted for the first
time using drone technology. This is first ever time, when AZGS had used drone
footage to review the fissures in this way. The huge crack formed between March
2013 and December 2014, and it is thought the fissure may have grown after
heavy rains in the fall of 2014. They’re experimenting with drone technology as
a tool for mapping fissures and other surface features like, landslides masses.
It seems a fresher crack, and could have been an underground void that reached
the surface after a monsoon in 2016.
The fissures, which are fairly
common in the Arizona desert, formed after 'extensive groundwater withdraws in
the Sonoran Desert. Moreover, a cluster of the cracks subsists around Eloy, and
in Cochise, La Paz, Maricopa, Pima and Pinal Counties, with the first having
opened up near Eloy in 1929. The giant fissures are precarious to people
off-roading and riding ATVs in the area, and also pose a risk to roaming
livestock who can fall in and get stuck. Therefore, it is also unsafe to stand
near the edge of a fissure due to the risk that it could suddenly cave in.
