Seismic Collapse Traps Five at Chile's El Teniente Copper Mine
O'HIGGINS REGION, CHILE, AUG 2 – A 4.2 magnitude tremor caused the collapse that killed one miner and trapped five others at Chile's El Teniente copper mine, with rescue teams working amid aftershocks and halted mining operations.
- Thursday at around 5.30 pm, a seismic event caused a collapse at El Teniente copper mine in O'Higgins Region, killing one worker, injuring nine, and leaving five missing.
- Authorities say the collapse followed a “seismic event” of uncertain origin, as Codelco investigates whether natural causes or mining activity caused the tremor.
- Rescuers have struggled to reach miners trapped 900 meters underground, as aftershocks have blocked access, delaying contact efforts for over 18 hours.
- Sernageomin launched an investigation and halted underground operations at El Teniente, while Williams vowed, “We are going to issue a provisional measure to halt operations in the underground sections of El Teniente,” and a yellow alert was issued for Machalí.
- Codelco faces long-term output challenges after the collapse, as the Andesita project, expected to produce 60,000 to 70,000 metric tonnes annually, faces delays despite its planned start this year.
