COPIAPO, CHILE — A massive sinkhole near the Alcaparrosa copper mine was first seen late last month close to Tierra Amarilla which is a town in Copiapo, Chile. It measured 82 feet in diameter and 650 feet in depth. After a couple of weeks, the sinkhole has now opened up to 119 feet in diameter.

All operations of the Alcaparrosa mine have been temporarily suspended.

Sinkholes form over time, but they often open up very abruptly. According to USGS, a sinkhole is “a depression in the ground that has no natural external surface drainage.”
