A one kilometer long and eight meters deep large crack in the Costa de Hermosillo, Mexico is baffling the locals and officials of La Candelaria.
The crack formed on August 17, 2014. Although social networkers believe it was created by an earthquake at the San Andres Fault, a geologist from the University of Sonora indicates that the ground has probably collapsed because of a stream of groundwater.
As shown in one of the pictures, this large earth crack has three perpendicular trenches. Maybe from side streams. Moreover at some places it is still covered. The soil in the area is very unstable, which makes the investigations more difficult.
