Peut-on stopper ces “gouffres” immenses et destructeurs ?

LUCAS EXPLAINS. Lately, I've come across several images of these sinkholes that suddenly open up and seem bottomless... In particular, this impressive hole that appeared in Guatemala and led to the disappearance of three people. The appearance of these holes, which cause significant damage to infrastructure, seemed quite mysterious to me. As I looked into the subject, I discovered that these very real phenomena also affect French municipalities. Behind all this, there are fascinating natural phenomena... but also human actions. Let me tell you about them.
