Overview

• Aftershocks from the July 31 tremor have waned, allowing rescue teams to prepare drones and remote-operated machinery for debris removal in the collapsed Andesita tunnels.
• The collapse, triggered by a magnitude 4.2–5 earthquake, killed one miner, identified as Paulo Marín Tapia, and injured nine others.
• Five workers remain uncontactable nearly 18 hours after the incident at depths of about 900 meters.
• Codelco has halted copper extraction in the affected zone, evacuated 3,000 personnel, and kept its concentrator and smelter operations running.
• The state miner has postponed its second-quarter financial report and launched an investigation into whether the seismic event was natural or mining-induced.
