Fortunately, the concept of eruption is now fully embedded in our daily lives, although some afiics tend to trigger manufactured and more harmful eruptions. They also made some smaller eruptions, for instance the famous "village hole" : it looks like a regular hole from the outside but in fact it is a deadly trap. At first it looks like a natural thing with no danger at all.

     But everybody think it's very powerfull. However praiseworthy it may be, they seldom solve problems. At times, I believe it would be faster to call the police directly.
