A gigantic chasm has opened in Chile, near the city of Tierra Amarilla, in the Atacama region. It has a diameter of about 25 meters and is about 200 meters deep. Sernageomin, the Chilean national body of geology and mining, has sent specialized personnel to understand what happened. It is not yet clear whether the local mining excavations have played a role, given that these cavities can also form for completely natural reasons: rainwater can in fact erode the surface layer of the soil causing subsidence. The chasm did not cause damage to people or things, but the event has generated strong concern among the local inhabitants, for fear that it may repeat itself.
