Three years after the giant sinkhole, residents of a mining town in Chile are still haunted by it

Residents of Tierra Amarilla, a mining town in the Chilean Desert, are hoping that a recent court ruling will ease their fears over a huge sinkhole which opened up near their homes three years ago but remains unfilled.

This month, a Chilean environmental court ordered Minera Ojos del Salado owned by Canada's Lundin Mining to repair environmental damages related to its Alcaparrosa Copper Mine, which it is believed to have caused the sinkhole to appear in 2022.

The company is required to fill the sinkhole and protect the water supply in the area. The cylindrical crater was originally 64 meters (210 feet) deep and 32 metres (105 feet) wide on the surface.

This has brought some relief to the residents of Tierra Amarilla, a region in central Atacama in Chile that is arid. They fear that if they don't fix it soon, this gaping hole will swallow more land.

Rudy Alfaro's home is located 800 meters away from the sinkhole. "We have lived in fear ever since it happened," he said. She said that a health center and preschool were also nearby.

We were afraid that it would grow, expand and move towards the houses.

She said that the sinkhole emitted dust clouds during a recent earthquake. This caused more anxiety.

The court confirmed that the Chilean environmental regulator had ordered the closure of the Alcaparrosa small mine in January. It also confirmed the "irreversible damage" to an aquifer which allowed water to drain into the mine, causing it to weaken the rock surrounding the mine.

Rodrigo Saez said, "This is harmful to an area which is already hydrologically stressed."

Lundin has said that it will work closely with the authorities to implement remediation. (Writing and editing by Rosalba o'Brien, Daina Beth Solon)
