Overview

• A 4.2-magnitude seismic tremor on Thursday caused a section of the El Teniente mine, 100 kilometers southeast of Santiago, to cave in
• Rescuers initially recovered two bodies and by Sunday located the remains of all five workers who had been unaccounted for, concluding the search
• Nine miners sustained injuries during the collapse and crews cleared roughly 20 percent of the blocked tunnels under strict safety measures before ending operations
• Authorities are probing whether the seismic event was a natural earthquake or was triggered by mining activity
• El Teniente reaches 1,200 meters below ground and produced over 350,000 tons of copper last year, making it a linchpin of Chile’s economy and the global market
