All over the world, the basements have become intensive exploitation territories, dug to their limits to meet energy and industrial needs. In some cases, this underground pressure ends up going up to the surface, upsetting the lives of those who live above. This is precisely what the mining collapse reveals in Chile, at the heart of a region already weakened by the lack of water and geological instability.
Over 800 meters separate the house of Rudy Alfaro from the crater, yet the anxiety has never left it. The presence of a health center and a nursery school in the immediate perimeter of the area accentuates collective fear. Some children, according to local testimonies relayed by Reuters, even demonstrate stress -related disorders.
With each seismic shock, the abyss releases clouds of dust that revives anxiety. Part of the population now hesitates to renovate their housing or invest in the local economy. This psychological instability has been installed at the same time as the geological fault, without one or the other having yet found a final solution.
The mining collapse in Chile reveals a problem of access to water
At the heart of this disaster is a much larger problem. The collapse was not caused by a natural event, but by the intensive extraction of the basement in an arid region. According to Discovery Alert, the water contained in a nearby aquifer has gradually been drained by the mine tunnels. This invisible phenomenon would have weakened the rocks, to the point of provoking the gigantic subsidence.
The impact is all the more serious since the Atacama region is among the driest in the world. The regional water director Rodrigo Saez said that this water loss is added to an already critical hydrological stress. The damaged aquifer provided part of the drinking water and irrigation needs for the city and its surroundings.
In September 2025, a court decision confirmed the irreversible nature of the damage suffered by this water table. The judges demanded that Lundin Mining, a Canadian company owner of Minera Ojos del Salado, initiates a process of filling the crater and puts in place water protection measures.
But the restoration of a water balance is not limited to filling a hole. It involves decades of surveillance, complex engineering works and rigorous monitoring of water quality throughout the watershed.
Why the population requires reform of environmental regulation
In Tierra Amarilla, distrust of the authorities and mining companies has turned into a political requirement. Since the incident, residents have requested an overhaul of the environmental control system. The initial inaction, combined with the period of three years before corrective measures were imposed, dug a chasm, this time in confidence.
Euronews recalls that the Chilean geological authorities suspended the operations of the AlcaParrosa mine in August 2022, without stopping the extension of the crater in the following months. The lack of transparency around responsibilities, as well as uncertainty about the future of the site, strengthens the feeling of abandonment.
Beyond the local case, the case illustrates the limits of an economic model which favors short-term profitability. Justice has recognized that the damage caused to the ground and water required a paradigm shift. From now on, several NGOs are demanding the establishment of buffer zones between mining farms and residential areas, but also the implementation of faster compensation mechanisms.
As natural and industrial earthquakes are multiplying, the population remains on the alert. Because in this region where the earth continues to tremble, it is no longer only the jolts that are scary, but the lack of lasting response.
