1. Incident Overview
On July 31, a 4.2-magnitude earthquake near Rancagua, Chile, caused a collapse at El Teniente – one of the world's largest underground copper mines. As of August 3, the accident has resulted in 6 fatalities (including 5 trapped miners) and 9 injuries. Search and rescue operations have concluded.

Key Facts:
◉ Historic Operation: Century-old mine with 4,500+ km of tunnels
◉ Production Impact: 356,000 metric tons copper output (2024)
◉ Emergency Response: Codelco suspended all operations in affected areas
◉ National Response:

• 3-day national mourning declared by President Boric

• Joint investigation launched (natural vs. induced seismicity)

• Criminal probe into safety compliance

2. Critical Safety Learnings
This tragedy highlights urgent industry vulnerabilities:

⚠️ Early Warning Failure
Abnormal acoustic signals detected days before collapse were not actioned
⚠️ Rescue Limitations
• 90-meter rock drilling challenge
• Continuous aftershocks hindering progress
• Complete communication blackout
⚠️ Structural Risks
Ageing infrastructure compounding geological complexity
