According to a Reuters report on the 8th, the sinkhole discovered on July 30 near a copper mine in Chile is getting bigger and bigger in recent days, “enough to engulf the Arc de Triomphe in Paris, France”.
It is reported that at the beginning of the discovery, the diameter of the tiankeng was about 25 meters; more than a week later, the diameter of the tiankeng has increased to 50 meters. This tiankeng is 200 meters deep and has accumulated water at the bottom. In addition to deploying tiankeng drainage operations, the authorities have also asked the copper mine to completely suspend production, and will soon launch an investigation into the underground operations of the copper mine.
Chile’s geological department said it would initiate a “sanctioning procedure,” but gave no details.
