A giant crack in the earth in Mexico has raised numerous questions and concerns. The crack was recently spotted on a piece of remote farmland.

Scientists are wondering what could have caused the crack and many people are theorizing that it could have been caused by an earthquake along the San Andreas Fault. They are worried that a strong earthquake could hit the region soon.

Other scientists believe that the crack may have been caused by the collapse of land on an underground stream.

The crack has caused a lot of problems for locals and many of the farmhands that work the land have been forced to go out of their way to get around the crack and avoid the unstable ground around it.

A second crack has also reportedly opened up nearby.

The crack has many locals worried that a large earthquake could strike the area soon.

Geologists at the University of Sonora are currently investigating the crack to determine what caused it. The investigators found that farmers had built up a levee to contain rainwater which had begun to leak, causing an underground stream which undermined the earth above it until it collapsed.

They are still trying to determine if the crack is a result of this stream or if it could really be a sign of an impending earthquake.

Experts are assuring the locals and everyone else worried about the crack, that it is not cause for alarm and that the crack is not likely a sign of an earthquake.

“It’s definitely not a cause for alarm for the population,” Martín Valencia Moreno, the head of the National Autonomous University of Mexico’s Regional Station of the Geological Institute, said. “It’s more something sensationalist and people like to encourage that sort of thing.”

“When a fault is generated the levels generally move and here we see people walking on both sides of the trench, the two levels are still in place, one side isn’t raised and the other hasn’t sunk either,” he added.

What do you think caused the crack?
